Multi-Vendor OI 0
To support multi-vendor OI, DDM-2000 OC-12 R7.0 supports Target ID AddressResolution Protocol (TARP) instead of Lucent Directory Service (LDS).DDM-2000 OC-3 R13.0, FiberReach R3.0, and FT-2000 OC-48 R8.0 also supportTARP, thus Lucent 2000 Product Family OI compatibility is still supported but notOI compatibility with previous releases of DDM-2000 and FT-2000. TARP is theestablished multi-vendor standard for SONET NEs that support TL1 OSinterfaces.
DDM-2000 OC-12 R7.0 is developed to be compatible with any other-vendor NEsthat also support TARP, OSI, IAO LAN, and TL1/X.25 as specified in BellcoreGR-253. In addition, DDM-2000’s TARP Manual Adjacency feature enablesDDM-2000 to operate in networks that include CMISE-based NEs which may notsupport TARP propagation.
DDM-2000’s compatibility with Tellabs TITAN * 5500/S R5.0 DCS, with TITANserving as the TL1/X.25 GNE for DDM-2000 TL1-RNEs, has been confirmedthrough cooperative joint testing. DDM-2000’s compatibility with some other-vendor NEs has also been tested by independent third-parties such as Bellcore.
Because DDM-2000 OC-12 R7.0 is intended to facilitate OS-based centralizedoperations, and because TL1/X.25 OS access is the key standardized multi-vendor OI application, the following Remote NE Status features are not supportedin DDM-2000 OC-12 R7.0:
■ Remote office alarms
■ Remote CIT alarm reports
■ Remote user panel indications
■ TBOS
■ Parallel telemetry.
All of the above features depend on the proprietary exchange of informationamong Lucent NEs in a subnetwork, specifically the communication of eachremote NE’s alarm status to other NEs. Although the Remote NE Status featureswere supported in previous releases of DDM-2000, such Lucent-only operationsfeatures in multi-vendor subnetworks would not include other-vendor NEs, due tothe lack of applicable standards, and thus would be incomplete.

Safety Instructions
Product Safety Labels
Important safety instructions are in this manual. In addition to the instructions onthe following page there are other safety instructions you must follow. Theseinstructions involve lasers, lightwave optical cable and connectors, andprecautions when handling circuit packs to prevent damage from electrostaticdischarge. This manual also contains admonishments in the form of DANGERS,WARNINGS, and CAUTIONS which must be followed at all times.
These admonishments have the following definitions:
■ DANGER indicates the presence of a hazard that will cause death orsevere personal injury if the hazard is not avoided.
■ WARNING indicates the presence of a hazard that can cause death orsevere personal injury if the hazard is not avoided.
■ CAUTION indicates the presence of a hazard that will or can cause minorpersonal injury or property damage if the hazard is not avoided. Thecaution is also used for property-damage-only accidents. This includesequipment damage, loss of software, or service interruption.
Other important safety instructions that you should read are in the "Operation andMaintenance" section of this manual. Only trained personnel should perform theprocedures in that section.
The alert symbol • appears throughout this product and in this manual to alert theuser to the presence of important operating and maintenance (servicing)instructions for the DDM-2000 OC-12 Multiplexer.
Lightwave Safety Guidelines
General Laser Information
Lightwave/lightguide systems, their associated test sets, and similar operationssystems (OS) use semiconductor laser transmitters that emit light at wavelengthsbetween approximately 800 nanometers and 1600 nanometers. The emitted lightis above the red end of the visible spectrum, which is normally not visible to thehuman eye. Although radiant energy at near-infrared wavelengths is officiallydesignated invisible, some people can see the shorter wavelength energy even atpower levels several orders of magnitude below any that have been shown tocause injury to the eye.
363-206-295About This Document
xliv Issue 1 December 1997
Conventional lasers can produce an intense beam of monochromatic light. Theterm monochromaticity means a single wavelength output of pure color that maybe visible or invisible to the eye. A conventional laser produces a small-size beamof light, and because the beam size is small the power density (also calledirradiance) is very high. Consequently, lasers and laser products are subject tofederal and applicable state regulations as well as international standards for theirsafe operation.
A conventional laser beam expands very little over distance or is said to be verywell collimated. Thus, conventional laser irradiance remains relatively constantover distance. However, lasers used in lightwave systems have a large beamdivergence, typically 10 to 20 degrees. Here, irradiance obeys the inverse squarelaw (doubling the distance reduces the irradiance by a factor of 4) and rapidlydecreases over distance.
Lasers and Eye Damage
Light energy emitted by laser and high-radiance LEDs in the 400-1400nm rangemay cause eye damage if absorbed by the retina. When a beam of light enters theeye, the eye magnifies and focuses the energy, magnifying the irradiance. Theirradiance of energy that reaches the retina is approximately 105 or100,000 timesthat at the cornea; and if sufficiently intense, may cause a retinal burn.
The damage mechanism at the wavelengths used in telecommunications isthermal in origin (that is, damage caused by heating). Therefore, a specificamount of energy is required for a definite time to heat an area of retinal tissue.Damage is not instantaneous. It occurs only when one looks at the lightsufficiently long that the product of the retinal irradiance and the viewing timeexceeds the damage threshold. Light energies above 1400 nm would causesurface and skin burns and do not affect the retinal area.
Classification of Lasers
Manufacturers of lasers and laser products in the U.S. are regulated by the Foodand Drug Administration's Center for Devices and Radiological Health (FDA/CDRH) under 21 CFR 1040. These regulations require manufacturers to certifyeach laser or laser product as belonging to one of four major Classes — Class I,II, IIa, IIIa, IIIb, or IV. Lasers are classified according to the accessibly emissionlimits and their potential for causing injury. Lightwave systems are generallyclassified as Class I, because, under normal operation conditions, all energizedlaser transmitting circuit packs are terminated on optical fibers which enclose thelaser energy with fiber sheath, forming a protective housing. Also, covers are inplace over the circuit pack shelves.

Lightwave Safety Precautions
In its normal operating mode, a lightwave system is totally enclosed and presentsno risk of eye injury. It is a Class I system under the FDA/CDRH scheme.
The lightguide cables that interconnect various components of a lightwave systemcan disconnect or break and may expose people to lightwave emission. Also,certain measures and maintenance procedures may expose the technician toemission from the semiconductor laser during installation and servicing. Unlikemore familiar laser devices, such as solid-state and gas lasers, the emissionpattern of a semiconductor laser results in a highly divergent beam. In a divergentbeam, the irradiance (power intensity) decreases rapidly with distance. Thegreater the distance, the less energy will enter the eye and the less potential riskfor eye injury.
Inadvertently viewing an unterminated fiber or damaged fiber with the unaidedeye at distances greater than 5 to 6 inches normally will not cause eye injuryprovided the power in the fiber is less than a few mW at the shorter wavelengthsand higher at the longer wavelengths. However, damage may occur if an opticalinstrument, such as a microscope, magnifying glass, or eye loupe, is used to stareat the energized fiber end.
! CAUTION:Use of controls or adjustments or performance of procedures other thanthose specified herein may result in hazardous laser radiation exposure.

Safety Precautions for Enclosed Systems
Under normal operating conditions, lightwave transmission systems arecompletely enclosed; nonetheless, the following precautions should be observed:
1. Because of the potential for eye damage, technicians should neitherdisconnect any lightwave cable nor splice and stare into the opticalconnectors terminating the cables.
2. Under no circumstances shall lightwave/lightguide operations beperformed by a technician before satisfactorily completing an approvedtraining course.
3. Since viewing lightwave emission directly with an optical instrument, suchas an eye loupe, greatly increases the risk of eye damage, an appropriatelabel must appear in plain view on the front of the main frame or lightguidetermination/interconnection equipment. The label shall read as follows:
NOTICE: UNTERMINATED OPTICAL CONNECTORS MAY EMITLASER RADIATION. AVOID DIRECT EXPOSURE TO THE BEAM. DONOT VIEW THIS BEAM WITH OPICAL INSTRUMENTS.

Safety Precautions for Unenclosed Systems
During service, maintenance, or restoration, a lightwave transmission system isconsidered unenclosed. Under these conditions, follow these practices:
1. Only authorized, trained personnel shall be permitted to do service,maintenance, and restoration. Avoid exposing the eye to emissions fromunterminated, energized optical connectors at close distances. Connectorsassociated with lightwave regenerators are recessed, which limitsexposure distance. However, technicians removing or replacingregenerators should not stare or look directly into the vacant regeneratorslot with optical instruments or magnifying lenses. (Normal eyewear orindirect viewing instruments, such as a FIND-R-SCOPE∗, are notconsidered magnifying lenses or optical instruments.)*
2. Only authorized, trained personnel shall use the lightwave test equipmentduring installation or servicing, since this equipment containssemiconductor lasers. (Some examples of lightguide test equipment areOTDR's, Hand-Held Loss Test Sets, and Feature Finders.)
3. Under no circumstances shall any personnel scan a fiber with an opticaltest set without verifying that all lightwave sources on the fiber are turnedoff.
4. All unauthorized personnel shall be excluded from the immediate area oflightwave transmission systems during installation and service.
Consult ANSI † Z136.1 American National Standard for Safe Use of Lasers forguidance on the safe use of lasers in the workplace.
Electrostatic Discharge (ESD) Considerations
! CAUTION:Industry experience has shown that all integrated circuit packs can bedamaged by static electricity that builds up on work surfaces and personnel.The static charges are produced by various charging effects of movementand contact with other objects. Dry air allows greater static charges toaccumulate. Higher potentials are measured in areas with low relativehumidity, but potentials high enough to cause damage can occur anywhere.

The following precautions should be observed when handling circuit packs inorder to prevent damage by ESD:
■ Assume all circuit packs contain solid state electronic components that canbe damaged by ESD. Use only Lucent Technologies’ manufacturedrecognized circuit packs in this system. Recognized circuit packs are listedin this user/service manual.
■ When handling circuit packs (storing, inserting, removing, etc.) or whenworking on the backplane, always wear a grounded wrist strap or wear aheel strap and stand on a grounded, static-dissipating floor mat. If a static-dissipating floor mat is used, be sure that it is clean.
■ Handle all circuit packs by the faceplate or latch and by the top and bottomoutermost edges. Never touch the components, conductors, or connectorpins.
■ Observe warning labels on bags and cartons. Whenever possible, do notremove circuit packs from antistatic packaging until ready to insert theminto slots.
■ If possible, open all circuit packs at a static-safe work position usingproperly grounded wrist straps and static-dissipating table mats. If a static-dissipating table mat is used, be sure that it is clean.
■ Always store and transport circuit packs in static-safe packaging. Shieldingis not required unless specified.
■ Keep all static-generating materials, such as food wrappers, plastics, andStyrofoam* containers, away from all circuit packs. Upon removal from thebay, immediately put circuit packs into static-safe packages.
■ Whenever possible, maintain relative humidity above 20 percent.

Introduction to the DDM-2000 OC-12Multiplexer 1
The DDM-2000 OC-12 Multiplexer is a single shelf SONET digital multiplexer. Asingle 12-inch shelf supports a mix of digital signal 3 (DS3), electrical carrier 1(EC-1), and optical carrier level 3 (OC-3) signals and multiplexes them into aSONET standard 622 Mb/s optical carrier level 12 (OC-12) rate.
The OC-12 and OC-3 optical lines, all transmission-affecting circuit packs, and the−48 V DC power feeders may be optionally protected. The shelf can be equippedto serve many diverse network applications and supports a variety of operationsinterfaces for current and evolving network operations needs.
The DDM-2000 OC-12 Multiplexer is designed for loop (access), interoffice(transport), and customer location applications. The DDM-2000 OC-12 Multiplexerstarts with many of the proven features of Lucent Technologies’ DDM-1000 andDDM-2000 OC-3 Multiplexers and extends into the future with the flexibility of theSONET standard.
The DDM-2000 OC-12 Multiplexer is designed for easy installation and operation.Installation is simplified with integrated test capabilities and default provisioning.Centralized operation is supported by a full set of single-ended control andmaintenance features. Built-in maintenance capabilities support both installationand system operation. A DDM-2000 OC-12 Multiplexer can be fully tested andinstalled without using external test equipment. Some tasks can be performedusing faceplate light-emitting diode (LED) displays and controls, while a craftinterface terminal (CIT) gives access to sophisticated maintenance, provisioning,and reporting features. A personal computer (PC) is needed to download softwareand to run CPro-2000 graphical user interface tool software.
The OC-12 Regenerator extends the span length of the DDM-2000 OC-12Multiplexer and is supported in both unbalanced and balanced modes. Diverserouting is supported in either mode, allowing one line to travel over a longer routethan the other. The OC-12 Regenerator uses the same shelf and some of thesame circuit packs as the OC-12 Multiplexer. See 363-206-207, "DDM-2000OC-12 Multiplexer and OC-12 Regenerator User/Service Manual" for moreinformation on the OC-12 Regenerator.
The DDM-2000 OC-12 Multiplexer has a phased release plan. This manual hasbeen issued to introduce Release 7.0 and will be updated to cover additionalreleases as they become available.

Release 1.0 and later features include OC-12 point-to-point with DS3 low-speedinterfaces, OC-12 hubbing with OC-3 extensions, and OC-3/OC-12 interworkingusing the 21D optical line interface unit (OLIU). The TL1/X.25 message-basedinterface to Bellcore's Network Monitoring and Analysis (NMA) operations systemfeature comes as part of the controller hardware and separately ordered softwarerequired with Release 1.1 and later equipment. Hardware features include the21D OLIU, which provides a short-reach multimode proprietary optical interface(IS-3) between the OC-3 and OC-12 shelves and the BBF2B TGS circuit pack,which provides DS1 timing outputs. Release 1.0 includes a security feature thatoffers security against unauthorized access to the CIT system functions. Logins,passwords, and user categories are provided. Security can be enabled ordisabled.
Release 2.0 new features include OC-3/OC-12 interworking using the opensystems interconnection (OSI) 7-layer protocol stack over the datacommunications channel (DCC). The OSI 7-layer protocol stack refers to the OSIreference model, a logical structure for network operations standardized by theInternational Standards Organization (ISO). Release 2.0 also includes opticalcarrier level 3 concatenated (OC-3c) transport. This OC-3c transport feature canbe used to interface with broadband terminals using 21D or 21G OLIUs.
SONET synchronization messaging is used to communicate the quality ofnetwork timing, internal timing status, and timing states throughout a subnetwork.The OC-12 23H/23H-U OLIU provides 1550 nm optics for long reach (100 km)central office applications.
Release 2.1 new applications include DDM-2000 OC-12/DACS IV-2000transmission interworking with an EC-1 interface, DDM-2000 OC-12/FT-2000OC-48 Lightwave System transmission interworking with an EC-1 interface, andOC-12 linear extensions from OC-3 rings. New features include an EC-1 interfacewith a new BBG12 3STS1E low-speed interface circuit pack, TL1 interface toBellcore's Operations Systems/Intelligent Network Elements (OPS/INE) Release1.7, and additional TL1 messages to support provisioning, maintenance, testing,performance monitoring, and security functions.
Release 2.2 new applications and features include interworking with SLC-2000Release 3.0, channel state provisioning, and additional TL1 commands andenhancements.
363-206-295System Introduction
1-4 Issue 1 December 1997
Channel state provisioning is a capability provided on DDM-2000 OC-12Multiplexers that suppresses reporting of alarms and events by supportingmultiple states (automatic [AUTO], in-service [IS], and not monitored [NMON]) forSTS-1 channels.
Release 2.3 provides OC-3 line state provisioning in addition to the features ofRelease 2.2. Line state provisioning allows in-service and not-monitored states ofOC-3 line level alarms on Function Unit OLIUs. The alarms can be squelched andremoved from the alarm report. Used in one-way OC-3c transport on OC-12 videoapplications.
Release 3.0 is an OC-12 STS-1 path switched ring release featuring EC-1 dualring interworking (DRI) with drop and continue and automatic synchronizationreconfiguration. New applications include OC-12 path switched ring, DDM-2000OC-12/DACS IV-2000 transmission interworking, and DRI interworking via anEC-1 interface. New features include DS3 low-speed interface on an OC-12 pathswitched ring, EC-1 low-speed interface with the BBG12 3STS1E circuit pack,two-fiber path switched ring, ten network elements’ maximum network from asingle maintenance point, STS-1 drop and continue, nonrevertive protectionswitching, automatic ring synchronization reconfiguration, OSI 7-layer protocolstack on the DCC in a ring, DS1 timing outputs for timing distribution,synchronization messaging, STS-1 signal degrade, manual STS path switching,enhanced security, remote and remote software download. The new BCP3 timeslot interchange (TSI FLEX) circuit pack provides flexible STS-1 bandwidthmanagement across the entire OC-12.
Release 3.1 new applications and features include interworking with SLC-2000Releases 3.1 and 3.2 ring networks, OC-12 STS-1/VT1.5 path switched ring (ring0x1 low-speed interface) optical interconnections between DDM-2000 OC-3 andOC-12 ring shelves (OC-3/IS-3), enhanced DS3 PM, channel state provisioning,OC-3 ring to OC-12 ring in-service upgrades, low-speed EC-1 loopbacks, andadditional TL1 commands and enhancements.
The OC-12 STS-1/VT1.5 path switched ring (ring 0x1 low-speed interface) OC-3/IS-3 interface offers a significant advantage over the 1+1 protected OC-3/IS-3interface for VT1.5 path switched ring applications. Ring (0x1) low-speed interfacemeans two service lines (no protection lines) are used between the OC-12Multiplexer ring and the OC-3 Multiplexer ring.
Ring 0x1 low-speed interfaces provide full VT protection switching via an OC-12ring, bandwidth conservation, and VT bandwidth management on the OC-12 ring.
Enhanced DS3 PM provides a collection (from the fiber or high-speed interface) ofthe DS3 parity-bit (P-Bit) and frame and multiframe (F&M) bit errored seconds,severely errored seconds, and unavailable seconds to the already providedcoding violations and severely errored frame seconds. The feature is mainly usedfor DS3 tariff verification.

The path trace signal is usedto verify path continuity by repetitively transmitting a fixed 64 bytelength string. The value of the transmit and receive expected pathtrace signal is provisionable. The value of the provisionable receiveexpected path trace signal is compared to the actual received pathtrace signal to verify continuity. This allows "labeling" of STS-1s andretrieval of the path by the "label” (for example, "ABC #1"). STS pathtrace requires the new BBG11B 3DS3 circuit pack.
363-206-295System Introduction

2Applications 2
Overview 2
The DDM-2000 Multiplexers serve a wide range of service applications in a widevariety of network configurations economically and efficiently. The first part of thissection, "Network Configurations," describes some of the network configurationsin which the DDM-2000 Multiplexers and related products can be used to providespecific service applications. The second part of this section, "ServiceApplications," describes some of the many service applications that can beserved with DDM-2000 Multiplexers.
Because the DDM-2000 Multiplexers are very flexible, most of the serviceapplications described in the second part of this section can be served with manyof the network configurations described in the first part. The particular networkconfiguration used for a particular service application depends on many factors,such as physical locations involved, including cost, mix of multiple services to beprovided with a single network, required interconnections to other networks, andother factors.

Introduction 2
DDM-2000 Multiplexers provide the flexibility required for operation in today'schanging telecommunications networks. With topology and capacity upgrades, aDDM-2000 network can be installed with minimum first cost and then easily grownto add new sites and new services. Many DDM-2000 circuit packs are commonwith other Lucent Technologies 2000 Product Family products, resulting in furthersavings as the network evolves.
The DDM-2000 OC-3 and OC-12 Multiplexers are also an ideal solution for privatenetwork and customer location applications. The DDM-2000 OC-3 and OC-12Multiplexers comply with electromagnetic compatibility (EMC) requirements perFCC Title 47, Part 15, and safety requirements per UL 1459 for equipment indedicated equipment rooms. The DDM-2000 Multiplexers also have CanadianStandards Association (CSA) Certification Standard C22.2 No. 225-M90.Standard access node configurations are available in Lucent's 51A, 80-type and90-type BRT-2000 cabinets. Fiber distribution of DS1 services is supported withthe DDM-Plus extension shelf or DDM-2000 FiberReach, which allows mixing ofDS1 line repeater interfaces for embedded metallic facilities and protected quadDS1 optical interfaces. DS0 and Integrated Services Digital Network (ISDN)services are supported from the SLC -2000 Access System through copper andfiber distribution.
The DDM-2000 FiberReach Multiplexer is the newest member of the DDM-2000product family and can be used in all DDM-Plus applications where increasedcapacity and integrated operations, maintenance, and provisioning features areneeded. Only representative DDM-2000 FiberReach Multiplexer applications areincluded in this section. For more application information, see 363-206-300,DDM-2000 FiberReach Multiplexer Applications, Planning, and Ordering Guide.

Network Configurations 2
This part describes many of the network configurations in which the DDM-2000Multiplexers can be used. In addition to the configurations specifically described,many other combinations of these network configurations can be used to meetspecific application needs.
Path Switched Rings 2
The need to prevent service outage caused by network failure has created a newclass of applications. The 2000 Product Family offers a wide range of self-healingnetwork features that automatically protect against service outage caused bycable cuts and equipment failures, which in turn protect customers and generateincreased revenue. These self-healing features include flexible DACS-basedrestoration with the ITM XM controller, FT-2000 OC-48 Lightwave System two-and four-fiber rings, DDM-2000 OC-3 and OC-12 virtual tributary 1.5 (VT1.5) andSTS-1 path switched rings, and SLC-2000 Access System path switched rings.
DDM-2000 OC-3, SLC-2000 Access System, and DDM-2000 OC-12 self-healingrings offer the performance and administrative benefits demonstrated by thesuccessful Lucent FT Series G Ring Diversity Switch. Since the DDM-2000 OC-3and OC-12 path switched rings operate in an integrated, single-ended fashion,complex network-level coordination is not necessary to restore traffic. This meansrestoration is faster and more reliable. Furthermore, bandwidth administration andnetwork reconfigurations (for example, adding or deleting nodes) can be easierbecause path switching does not require special time slot assignment rules.
363-206-295Applications
2-4 Issue 1 December 1997
The DDM-2000 OC-3 and OC-12 VT1.5 or STS-1 path switched rings operate asshown in Figure 2-1(a.). Traffic entering a path switched ring node is sent ontoboth rotations of the ring. At the receiving node, the signal having the highestintegrity (based on SONET path information) is selected and dropped as outgoingtraffic. At intermediate nodes, the traffic is "passed-through" without changing theSONET path information. The DDM-2000 OC-3/OC-12's VT1.5/STS-1 Time SlotInterchange (TSI) capabilities make the provisioning of add/drop and pass-through traffic quick and easy.
In addition, the backup and restoral capability of CPro-2000 can be used tosignificantly reduce the effort and increase the accuracy of installing severalcomplex ring shelves having similar or identical configurations. After manuallyprovisioning the first node, CPro-2000 can be used to make a copy of theconfiguration. This copy can then be used to quickly and easily configure all of theremaining nodes using the restoral feature of CPro-2000. Using system backupand restoral in this fashion provides a much quicker and less error-proneinstallation than manual provisioning.
The self-healing nature of the path switched ring is shown in Figure 2-1(b.). In thiscase, the fiber failure between nodes C and D causes node C to switch from thecounterclockwise ring to the clockwise ring, thus maintaining service betweennode A and C.
A network which requires the bulk of its traffic to be dropped at a single node is anideal application for path switched rings. A typical loop feeder network, wheremost traffic is between the subscriber loop to a central office, fits this mold. Suchan application calls for the delivery of protected DS1 and DS3 service to customerlocations. In many cases, where the network serves only voice traffic and DS1s, aDDM-2000 OC-3/SLC-2000 path switched ring is a perfect fit. If DS3 service or amixture of DS1 and DS3 service is needed, multiple OC-3 rings or an OC-12 ringmay be necessary. Cost, fiber availability, and bandwidth flexibility all play a part indetermining whether a single OC-3 ring, multiple OC-3 rings, or an OC-12 ring willbe the best network solution.

OC-12 Path Switched Rings 2
The DDM-2000 OC-12 Multiplexer provides STS-1/STS-3c level path protectionswitched ring capability. As shown in Figure 2-2, it provides transport of 12 DS3s,12 EC-1s, 4 OC-3cs, or a mixture with path switching at the STS-1 level (STS-3clevel for OC-3c traffic). Such a ring provides an economical, flexible, and reliablesolution for loop feeder networks.

Figure 2-3 shows how DDM-2000 OC-3 and OC-12 Multiplexers can be usedtogether to provide a path switched ring operating simultaneously at the VT1.5,STS-1, and STS-3c levels. This ring is especially useful for loop feederapplications with large bandwidth needs. It can also be developed as a result ofan upgrade from an OC-3 ring in an environment where growth has exhausted thebandwidth of the OC-3 ring.

If fiber exhaustion is a problem, the 2000 Product Family provides severalalternatives for the network planners to pick from, depending on the specifics oftheir application. If fiber is available, multiple DDM-2000 OC-3 Multiplexer ringscan be installed; or if fiber is unavailable or if the administrative ease of a singlering is desired, a single DDM-2000 OC-12 Multiplexer ring can be installed. Fiberexhaustion often occurs when customer demand for voice, DS1, and DS3services grows to fill the OC-3 ring's capacity. If the growth has come from onlyone or two sites and there is spare fiber in place, these high demand sites may becut to a new OC-3 ring without interrupting service. Alternatively, driven by fiberexhaustion or evolution to customer DS3 services, the OC-3 ring may beupgraded in service to an OC-12 ring. In this configuration (Figure 2-4),DDM-2000 OC-3 Multiplexer equipment is co-located with a DDM-2000 OC-12Multiplexer shelf to provide a unified VT1.5 path switched ring node with an OC-12high-speed interface.

VT1.5 bandwidth rearrangement is available which allows the unused VT1.5sfrom an STS-1 dropped at one site to be dropped at other sites. All DDM-2000OC-3 and OC-12 Multiplexer shelves connected together in this subnetwork cancommunicate, using the single-ended operations capability of DDM-2000Multiplexers. Once the DDM-2000 Multiplexer OC-12 ring is in place, it can beused by itself to provide STS-1 level path switching with DDM-2000 OC-3Multiplexers to provide VT1.5 level path switching, or in a mixed configurationwhere both STS-1 level and VT1.5 level switching are supported simultaneously.
The link between the DDM-2000 OC-12 and OC-3 Multiplexers is 0x1 protectedfor this ring configuration. In this case, the DDM-2000 OC-12 Multiplexer feedsSTS-1s directly off of each ring rotation to the DDM-2000 OC-3 Multiplexer wherepath switching is done. Switching is not done on the DDM-2000 OC-12Multiplexer; rather VT1.5 or STS-1 level switching is done on the DDM-2000 OC-3Multiplexer. Interconnecting the DDM-2000 OC-12 and OC-3 Multiplexers via a0x1 interface allows the same STS-1 to be dropped to DDM-2000 OC-3 shelves atseveral nodes on the OC-12 ring. This combination of interconnected DDM-2000OC-12 and OC-3 Multiplexers provides full VT1.5 switching granularity across theentire OC-12 bandwidth at any node on the ring, resulting in a full-fledged VT1.5path switched OC-12 ring.
The DDM-2000 OC-12 path switched ring can be used in conjunction with theDDM-2000 OC-3 Multiplexer by an access provider to provide OC-3 ring serviceon an OC-12 ring for end users. It is becoming more frequent that a single enduser desires a virtual private network from an access provider to connect severalsites in a metropolitan area together. It is accomplished by deploying a DDM-2000OC-12 ring in conjunction with DDM-2000 OC-3 Multiplexers. As describedpreviously, the DDM-2000 OC-3 Multiplexers provide VT1.5 and STS-1 pathswitching; however, in this case, they are placed at end-user locations. TheDDM-2000 OC-3 equipment is then used exclusively by that end user and threeSTS-1s worth of bandwidth are reserved on the OC-12 ring for that end user.
The end user is given log-on privileges to the OC-3 equipment located on theirpremises, allowing them to gather performance data, provision service, andadminister their virtual OC-3 ring network. From the end user's point of view, theyhave a virtual OC-3 ring network at their disposal.

For customers who have significant bandwidth demands or whose geographicalsituation requires additional OC-3 shelves from a single OC-12 location,Figure 2-5 shows how these applications can also be met. In addition, diverserouting to two separate OC-12 shelves can increase the reliability of the networkeven further.

In a ring configuration, the DDM-2000 OC-12 Multiplexer can provide two high-speed optical interfaces. At a 1310 nm wavelength, it supports a span length of upto 51 kilometers (32 miles) without regenerators. At a 1550 nm wavelength, itsupports a span length of up to 100 kilometers (61 miles) without regenerators.Regenerators or add/drop systems can be used to increase the distances for1310 nm installations.
Each ring node can be independently synchronized from a Building IntegratedTiming Supply (BITS) clock. This BITS clock can also be timed using theDDM-2000 DS1 timing output feature.
OC-12 STS-1/VT1.5 Path Switched Ring (0x1) 2
The DDM-2000 OC-12 ring supports (0x1) OC-3/IS-3 interfaces in its FunctionUnit slots. These interfaces must be provisioned as 0x1. Signals pass through theDDM-2000 OC-12 transport ring and exit to the DDM-2000 OC-3 ring. OC-12Function Unit slot FN(x)-1 is connected to OC-3 Main-1 and OC-12 Function Unitslot FN(x)-2 is connected to OC-3 Main-2. Switching is not done on theDDM-2000 OC-12 Multiplexer on these lines, or paths on these lines; rather VT1.5or STS-1 level path switching is done on the DDM-2000 OC-3 Multiplexer. Thisallows DDM-2000 OC-3 nodes running ring software to interface with DDM-2000nodes of an OC-12 ring in such a way as to provide ring-on-ring architecture.Each OC-3 ring so supported occupies up to three STS-1 time slots on the OC-12ring. Each OC-12 node can provision the same STS-1 time slots as other OC-12nodes to drop to the OC-3 shelf (to share STS-1s among several OC-3 shelves) orthe OC-12 node can provision different STS-1s at different sites. With 0x1operation, the OC-12 ring passes the contents of these STS-1 time slots betweenthe low-speed OC-3/IS-3 lines and OC-12 high-speed lines without terminatingthem or performing any path protection switching on them. Up to four OC-3 ringscan be supported in this fashion by an OC-12 ring to maximize the OC-12bandwidth utilization. This allows access to any and all VT1.5 signals at anOC-12 site. Since the high-speed signals from the OC-3 ring(s) are sent as twocopies (one clockwise, the other counter-clockwise) on the OC-12 ring, the OC-12ring capacity is limited to the OC-12 line rate.
The OC-3/IS-3 lines between an OC-12 node and an OC-3 node connected in aring (0x1) fashion, behave like the OC-3 lines between the nodes on an OC-3 ringand do not perform line level protection switching. Instead, the OC-3 shelvesperform the normal path protection switching functions.

Folded Ring 2
DDM-2000 OC-3 and OC-12 rings offer several benefits in addition to serviceassurance. Economically, a ring network minimizes overall network cost byrequiring fewer optical transmit/receive units than a comparable linear add/dropnetwork. Operationally, a ring network provides significant flexibility to increasebandwidth at existing nodes and to add new nodes at locations whereunanticipated bandwidth is required.
These benefits make rings highly desirable even when fiber route diversity is notavailable. When route diversity is not available on part or all of the ring, ringtechnology can be used to support split and tapered feeder routes to deriveeconomic benefits, provide bandwidth flexibility, ease the process of adding anddeleting nodes and supply survivability against single-node failures.
When route diversity is not available or fiber cable cuts are not a driving concern,the two-fiber path switched ring feature can be applied in a "folded" (a folded ringis a single path ring) configuration (Figure 2-7). This use of DDM-2000 OC-3,OC-12, and SLC-2000 access resource manager (ARM) path switched ringsapplies in particular to hubbing and linear topologies where there is no return pathfrom the end remote site to the central office (CO). While a complete cut throughthe fiber cable cannot be protected, single-node equipment failures are stillprotected. Furthermore, a two-fiber ring ARM uses only one optical transmitter/receiver in each direction (two per remote shelf), in contrast to a 1+1 lineprotection arrangement that requires four optical transmitter/receivers per remoteshelf. Thus the ring configuration reduces equipment costs, a benefit independentof its survivability advantage. The ring topology also makes node addition/deletionstraightforward.

OC-3 Ring Transport on OC-12 Point-to-Point 2
Rings that cover a large geographical area or interconnected path switched ringsare a cost effective and popular way for a service provider to offer these highpriority services. Figure 2-8 shows a ring configuration using DDM-2000 OC-3ring nodes with DDM-2000 OC-12 point-to-point nodes to provide a high-serviceavailability architecture. This configuration will survive fiber, equipment, andcatastrophic office failure, since it provides an alternative service path through asecondary CO and uses the path switching ability of the DDM-2000 OC-3 toselect between these two paths. In this example, the OC-12 NEs are connectedas folded rings in a point-to-point configuration; 0x1 cross-connects are used toconnect with the OC-3 rings.

Dual Homing 2
End-users are demanding service with higher and higher availability. Serviceproviders are responding with tariffs that rely on self-healing networks to offersuch high availability service. Some of these tariffs even call for penalties for theservice provider when service is interrupted or has a high error rate. The LucentSONET product family offers many options for meeting these service needs.
OC-1 Ring transport on OC-3 Ring and OC-3 Ring transport on OC-12 ringnetworks can be implemented in dual homing configurations.
Dual Ring Interworking (DRI) 2
In an interconnected ring or DRI topology, two rings are connected together at twogeographically separate nodes. In addition to the facility and node failureprotection that a single ring provides, the dual node interconnection between therings provides an automatic alternate route in the event of a catastrophic failure atone of the interconnecting nodes. Typically, such a topology is used tointerconnect a loop feeder access ring to a higher bandwidth interoffice ring asshown in Figure 2-9. This architecture can withstand any single equipment or fiberfailure in each of the rings or a failure (which could range from a CO shutdown inthe case of fire, for example, or equipment failure, or failure of the facilityconnecting the two rings) of either of the two interconnecting nodes without losingservice on either the access ring or the interoffice ring. Such a catastrophic failurewould cause a service outage for a simple ring architecture.

As Figure 2-10 shows, DRI allows a circuit (for instance, between nodes A and Z)with one termination in the upper ring and the other termination in the lower ring tosurvive a failure of the shared node that is currently carrying service for the circuit.The failure is depicted by an "X" in the figure. The two shared nodes are in CO Band CO C. Both nodes have the signal available to them at all times. When afailure occurs, the two terminating nodes and the two shared nodes switch so thattraffic is carried through CO C and around the node failure.

DDM-2000 OC-3, OC-12, and FT-2000 OC-48 Lightwave Systems can beconfigured to offer this topology. Often the DDM-2000 equipment is used for theloop feeder access ring, and the FT-2000 OC-48 Lightwave System equipment isused for the interoffice ring. Figure 2-11 shows a DDM-2000 OC-3 (or OC-12)path switched ring interworking with an FT-2000 OC-48 Lightwave Systembidirectional line-switched ring.
In this application, the DDM-2000 provides an appearance of loop traffic at boththe primary and secondary nodes by dropping traffic at the primary node andsimultaneously continuing it on to the secondary node. This capability is called"drop-and-continue." The DDM-2000 OC-3 Multiplexer allows DS1 signals to bemultiplexed for handoff at an economical EC-1 or OC-3 rate in the COs. Also, theDDM-2000 OC-3's flexible TSI can be used to prepackage all DRI protected DS1sinto a single EC-1 for economical handoff to the OC-48 ring. This capability allowsfor the easy mixing of DRI and non-DRI services on the same ring network. In thisway, only specially tariffed services need to be configured for the extra reliabilitythat DRI provides. DS3/STS1 clear channel services are also supported. Thecompanion FT-2000 OC-48 Lightwave System ring picks up the traffic at these twonodes and carries it to the destination node, unless a failure condition causes aprotection switch to the secondary signal. In the reverse direction, a similarprocess is followed with the OC-48 ring handing off the two copies of the signal atthe primary and secondary nodes and the OC-3 ring providing the switching at thedestination node.

The DDM-2000 drop-and-continue feature also finds an excellent application ininterconnecting two rings via an intermediate transport network. In the exampleshown in Figure 2-12, DDM-2000 OC-3 Multiplexer access rings act as a DRI pairvia an FT-2000 OC-48 Lightwave System and DACS IV-2000 interoffice network.The advantage of this network is the grooming for DRI traffic provided by theDACS IV-2000. Both DDM-2000 OC-3 rings provide drop and continue at each oftheir two duplicate COs. Both copies of the signal are transported as separatetributaries through the interoffice network, and path switching is implemented atthe edges of the network. Signal redundancy is preserved on an end-to-end basis.
In offices where SONET interconnections are not available, DS3 interfaces can beused between dual OC-12 offices. The DDM-2000 OC-12 Multiplexer alsosupports DS3 DRI in addition to the EC-1 and OC-3 interfaces. In the event of anincoming DS3 failure from the DSX-3, the OC-12 Multiplexer inserts an STS-1 AISsignal into the STS-1 ring channel used by the DS3 to activate the downstreamSTS path protection switch. It is recommended that SONET DRI interfaces (EC-1or OC-3) be used if possible since the DS3 to STS-1 AIS translation feature is onthe OC-12 Multiplexers only (R5.1 and later).

OC-3 Linear Optical Extensions from OC-3 andOC-12 Rings 2
An additional topological flexibility offered by the DDM-2000 OC-3 and OC-12Multiplexers is 1+1 protected linear OC-3 and IS-3 optical extensions from OC-3and OC-12 rings. Using this capability, the DDM-2000 OC-3 and OC-12Multiplexers can support many of the new network configurations desired in theevolving loop feeder environment. As Figure 2-13 shows, an access provider canuse linear optical extensions from an OC-12 ring to provide OC-3/OC-3c signalsdirectly to end users. This gives the end users the bandwidth they need for largebandwidth applications, such as video, and provides it to them via the pathswitched ring architecture they require for high service availability. If enabled, fullsingle-ended operations are available on all network elements (NEs). This givesthe end user full control of performance monitoring (PM) data, networkreconfigurations, and provisioning of the network.
OC-3 optical extensions can also be used to interconnect SONET subnetworks.Examples include interconnection of two access networks and interconnectionbetween access and interoffice rings. Optical extensions can be used tointerconnect OC-3 and OC-12 ring subnetworks to an OC-3 terminal, OC-3 andOC-12 add/drop networks, and another OC-3 or OC-12 ring.

Initial deployments can be sizedaccording to current needs and near-term forecasts, which minimize the network'scost. As large-scale growth occurs (for example, DS1 and DS3 serviceexpansion), the DDM-2000 OC-3 and OC-12 Multiplexers can be rearranged tomatch each application.
The upgrade from a DDM-2000 OC-3 point-to-point system to a DDM-2000OC-12 system can be done without interrupting service. The procedure convertsthe DDM-2000 OC-3 Multiplexer shelves so that they interconnect with theDDM-2000 OC-12 Multiplexer shelf. The resulting high-capacity, point-to-pointconfiguration is shown in Figure 2-14. The larger bandwidth accommodatesadditional DDM-2000 OC-3 Multiplexers for DS1 access.
In addition to upgrading an existing OC-3 network, the DDM-2000 OC-12Multiplexer also provides DS3, EC-1, OC-3 or OC-3c service transport between aremote site and a CO. It can do this in either a stand-alone (terminal) configurationor, if desired, it could be connected directly to a DACS IV-2000 Cross-ConnectSystem using DS3 or EC-1 interfaces.

Like the loop feeder point-to-point applications, the interoffice DDM-2000 OC-3point-to-point Multiplexer application supports smooth in-service capacityupgrades using the DDM-2000 OC-12 Multiplexer (Figure 2-15). The initialDDM-2000 OC-3 Multiplexer shelf is connected in service to the DDM-2000OC-12 Multiplexer, allowing high-speed interconnection between offices. TheDDM-2000 OC-12 Multiplexer is also well suited for stand-alone interofficetransport of high-capacity DS3, EC-1, and OC-3c signals. The DDM-2000 OC-12Multiplexer offers two high-speed optical interfaces: at a wavelength of 1310 nm, itsupports a 51 kilometer (32 miles) span length; and at a wavelength of 1550 nm, itsupports a 100 kilometer (61 miles) span length.
Like the DDM-2000 OC-3 Multiplexers, the DDM-2000 OC-12 Multiplexers allowindependent synchronization of each site from its own office clock and disablingsingle-ended operations when the application crosses a maintenance boundary.Timing can be passed from one office clock to another with a DS1 timing outputderived from an incoming OC-12 signal.

Service Applications 2
Loop Feeder 2
The DDM-2000 Multiplexers provide a full set of interfaces, topologies, operationsand upgradability to provide the flexibility and ease of operation required to meetthe dynamic requirements of the loop feeder environment.
The DDM-2000 Multiplexers are particularly suited to the evolving needs of loopfeeder applications. They offer many essential features: compact size,environmental hardening, single-ended operations, and capacity and topologyupgrades. The DDM-2000 Multiplexers' extensive set of topologies allows thenetwork to be optimized for a particular route geography, service mix, and growthforecast.
Interoffice Transport 2
The DDM-2000 Multiplexers provide the features necessary for interofficetransport applications. Examples include long span optics, OC-12 regenerators,easy capacity upgrades, and full DS1 and DS3 add/drop capability. Interofficeapplications include point-to-point, stand-alone SONET electrical multiplexing,add/drop, path switched ring, and DRI.
The DDM-2000 OC-3 and OC-12 Multiplexers provide the following features forinteroffice applications:
■ DS1 transport
■ DS3 transport
■ EC-1 transport
■ OC-3c transport
■ Synchronization distribution
■ Single-ended or independent operations
■ Single-mode fiber spans up to 55 kilometers (34 miles) for OC-3, up to 51kilometers (32 miles) for OC-12 at a wavelength of 1310 nm, and up to 100kilometers (61 miles) for OC-12 at a wavelength of 1550 nm.
A VT1.5/STS-1 path switched OC-3 ring is a very effective self-healing networkconfiguration for small cross-section interoffice networks, such as outstate trunks.
Any number of nodes in a DDM-2000 interoffice network can be independentlysynchronized from a BITS clock. Timing inputs can also be provided to the BITSfrom a DDM-2000 OC-3 or OC-12 Multiplexer using the DS1 timing output feature.

Broadband Business Access 2
New telecommunications needs for customer networks include higher bandwidthservices based on DS1, DS3, and STS-3c rates; a self-healing capability forbusinesses most sensitive to service disruption; and rapid service deploymentand rearrangement to keep pace with a changing environment. The flexible,advanced capabilities of the DDM-2000 OC-3 and OC-12 Multiplexers create apowerful platform along with other Lucent 2000 Product Family systems to keeppace with these dynamic customer needs.
The more a business relies on telecommunications, the more important self-healing networks become. In particular, finance, medical, transportation,education, and government users are insisting on a highly reliable network. Theseusers are also driving for higher bandwidth data and video services.
The large multi-site medical facility shown in Figure 2-19 uses broadband servicesfor inter-site imaging and video needs as well as lower bandwidth voice and dataservices into the public network based in ISDN primary rate interface (PRI) andbasic rate interface (BRI) interfaces. These services can be delivered efficientlywith the DDM-2000 OC-3, OC-12, and SLC-2000 Access System's flexible TSIand add/drop capabilities. The ring architecture prevents service outage due to acable cut or node failure.

STS-3c Video Broadcast Application 2
Video applications are becoming increasingly more important in the competitive homeentertainment industry. The DDM-2000 OC-12 Multiplexer can be the backbone forvideo distribution needs as it supports two STS-3c video cross-connection types:
■ COV - Video cross-connections at central offices
■ RTV - Video cross-connections at remote terminals
Figure 2-20 shows the video broadcast application for the DDM-2000 OC-12Multiplexer. In this application, incoming STS-3c signals at a "head-end" (cross-connection type COV) OC-12 shelf are simultaneously dropped at any number ofremote OC-12 terminals (cross-connection type RTV). This provides the capability ofsimultaneously transmitting up to eight STS-3c video feeds (using both slots of fn-A/B/Cand D, when equipped with OC-3 or IS-3 interfaces) to remote sites.
Significant features of this application are:
■ Both inner and outer rings (mb1 and mb2) distribute up to four STS-3cunprotected one-way signals. These signals are then connected to OC-3 or IS-3circuit packs.
■ The STS-3c signals can be provisioned in pairs (two, four, six, or eight) andunused time slots can be used for other ring applications.

STS-3c Video Application ATM Interface 2
Figure 2-21 shows the video application for the DDM-2000 OC-12 ring used totransport STS-3c signals from one ATM switch to another. In this scenario, eachOC-12 shelf is cross-connected and provisioned as COV type. This provides thecapability of transmitting a point-to-point STS-3c video signal from one shelf toanother. Significant features of this application* are:
■ Both inner and outer rings (mb1 and mb2) distribute up to four STS-3cunprotected one-way signals. These signals are then connected to OC-3 orIS-3 circuit packs.
■ The STS-3c signals can be provisioned in pairs (two, four, six, or eight) andunused time slots can be used for other ring applications.
Figure 2-21. STS-3c Video Broadcast Application for ATM Interface
* Customer experience with this application has revealed compatibility issues with somebrands of ATM equipment (e.g., Cisco, Bay Network). For ATM support it is stronglyrecommended to use the STS-3c 0x1 application features provided in OC-12 Release 5.2and later ring releases, unless an unprotected scheme is acceptable.

Locked STS-3c (0x1) Broadband Services 2
Beginning with Release 5.2 the DDM-2000 OC-12 ring will transport STS-3c 0x1services through OC-3/IS-3 interfaces in its function units. These interfaces must beprovisioned as 0x1.
STS-3c path switching does not take place on the DDM-2000 OC-12 ring; it isexecuted elsewhere in the network (e.g., when the OC-12 ring transports ATM STS-3ctraffic path switching is performed through the external ATM-based router).
Figure 2-22 shows an STS-3c 0x1 application. Each OC-12 node provisions the samedropped STS-3c time slot as other nodes on the same ring. For different applications,an OC-12 node can assign the other STS-3cs to different time slots at different sites.With 0x1 applications the OC-12 ring passes the contents of these STS-3c time slotsbetween the low-speed OC-3/IS-3 lines and the OC-12 high-speed lines withoutterminating them or performing path protection switching.
Since the STS-3c traffic is received by the low-speed interfaces and transmitted astwo copies on the OC-12 ring (one clockwise, one counterclockwise), the ring capacityis limited to the OC-12 line rate.

Teleprotection and Supervisory Control and DataAcquisition (SCADA) Applications 2
Electric utilities are facing an unprecedented demand for increasedcommunications bandwidth to support modern operations and businessapplications such as substation automation, computer networking, and videoteleconferencing. Many electric utilities are installing SONET fiber opticbackbones to meet these needs. SONET fiber optic backbones are a valuablecommunications resource that can also be used for real time protective relay andSCADA applications.
DDM-2000 OC-3, DDM-2000 OC-12, and DDM-2000 FiberReach Multiplexerscan be used in a flexible backbone network among electrical substations andother important sites. These systems provide an innovative "locked cross-connection" feature that enhances the ability of SONET rings to transportprotective relay and SCADA communications. The locked cross-connectionfeature meets the teleprotection requirements for minimum and stabletransmission delay, minimum system outage during a protection switch, and DS0level bandwidth management at all ring nodes.
The locked cross-connection feature allows a DS1 to be removed from theTR-496 compliant VT path protection switching algorithm and provisioned as anunprotected path between any two nodes on the ring. As shown in Figure 2-23,locked cross-connection can be used to interconnect adjacent nodes all the wayaround SONET rings, thereby permitting access to the DS1 at each SONETnode. Figure 2-23 shows a single DS1 locked between ring nodes, but this canbe extended to an arbitrary number of DS1s within the available SONETbandwidth. This locked cross-connection feature fixes the ring rotation (anddelay) of the DS1 paths on the ring and also permits DS0 grooming of the DS1sat each DDM-2000 or DDM-2000 FiberReach node using an external drop/insertmultiplexer, such as the RFL 9001 Intelligent Multiplexer. Figure 2-23 shows theDDM-2000 interconnecting at the DS1 level with an adjacent RFL 9001 IntelligentMultiplexer that, in turn, connects on the low-speed side to protective relay andSCADA equipment. Specially designed channel units in the RFL 9001 IntelligentMultiplexer detect when a fault occurs on the power line or substation andcommunicate at the DS0 level with other substation nodes to isolate the powergrid fault.
In addition to the efficient DS0 grooming capability, the RFL 9001 IntelligentMultiplexer implements its own protection algorithm that can restore the DS0level circuits within the locked cross-connections should the ring be cut. Thisalgorithm operates much faster than the SONET TR-496 algorithm, therebyminimizing system outage during a protection switch.

Issue 1 December 1997 2-37
Figure 2-23 also shows an optical drop/insert DS1 extension from the SONETrings implemented with RFL 9001 Intelligent Multiplexers. This extension is usefulfor serving low bandwidth sites remote from the SONET backbone. The figureshows a single host DDM-2000 interconnecting the rings, but the applicationcould be a DRI to provide node survivability.

Intelligent Vehicle Highway System (IVHS)Applications 2
IVHSs are beginning and will grow to play a major role in the roadway systems ofthe future. Their primary use in the near-term is to reduce congestion. This isdone in several ways.
■ The IVHS provides more efficient and optimal traffic management whichattempts to avoid congestion in the first place.
■ The IHVS provides better management of congestion caused by randomoccurrences such as accidents or breakdowns.
■ The IVHS eliminates many of the foreseeable causes of congestion, suchas toll-taking, by automating these functions.
In the future, these systems will also help travelers plan their routes by providingup-to-the-minute traffic and highway information. The DDM-2000 OC-3 andOC-12 Multiplexers are a perfect match for the networking needs of thesesystems.
Figure 2-24 shows a typical IVHS application. An IVHS network calls for carryingdata between roadside equipment, such as traffic counters, speed sensors,variable messaging signs, video cameras, toll-taking equipment, pay phones andcall boxes, and a traffic operations center where incoming data is processed andresponses are generated. The DDM-2000 OC-3 and OC-12 Multiplexers providea perfect backbone for carrying this information. The DDM-2000 OC-3 MultiplexerSONET ring capability, when coupled with diverse fiber routing on opposite sidesof the roadway, makes the backbone completely self-healing in the face offailures. Such reliability is absolutely essential, especially as travelers come todepend more and more on IVHS networks. The VT1.5 and STS-1 bandwidthmanagement capabilities of the DDM-2000 OC-3 and OC-12 Multiplexers allowflexible allocation of bandwidth to match the dynamics of a roadway system,which is undergoing unpredictable changes in traffic patterns, breakdowns,accidents, and repairs. Such bandwidth management provides a system whichmeets the IVHS network needs in a cost-effective manner. DDM-2000 OC-3 andOC-12 Multiplexers completely meet the transmission needs of an IVHS network.

DDM-2000 OC-12 Multiplexer ShelfConfigurations 3
A DDM-2000 OC-12 Multiplexer path switched ring shelf supports all OC-12 ringapplications.
■ The following circuit packs are required in all DDM-2000 OC-12 Multiplexerpath switched ring applications:
— 177C APPBLK in the main A slots to control air flow through theshelf to ensure adequate cooling.
— 23G/23G-U or 23H/23H-U OLIU circuit packs in the main B slotsprovide the OC-12 optical interfaces.
— BCP3 TSI circuit packs in the TSI slots connect STS-1s from themain B slots to the FN slots. The BCP3 TSI also distributes thetiming it receives from the BBF2B/BBF4 TGS/TG3 circuit packs tocircuit packs in the main and FN slots.
— BBF2B/BBF4 TGS/TG3 circuit packs in the TIMING slots providetiming to the BCP3 TSI circuit packs.
— BBG8 SYSCTL and BCP4 OHCTL circuit packs in the SYSCTL andAUXCTL slots, respectively, provide system control functions.
■ For all but the SYSCTL and OHCTL, which are not protected, installation ofprotection circuit packs is optional. Equipage of function unit slots dependson the application.
■ Unused FN slots must be equipped with 177B APPBLK to ensureadequate cooling of the shelf.
■ All applications should be equipped with a baffle as shown inED-8C727-10.

OC-12 STS-1/VT1.5 Path SwitchedRing Configuration 3
Figure 3-5 shows a DDM-2000 OC-12 Multiplexer STS-1/VT1.5 path switchedring configuration. As in the DDM-2000 OC-12 Multiplexer STS-1 ring shelf, thereis one set of OC-12 interfaces and a pair of TSI FLEX circuit packs. In thisconfiguration, however, there is also an IS-3 interface to a DDM-2000 OC-3Multiplexer shelf where VT1.5 level path protection switching is completed. Thisinterface between DDM-2000 OC-3 and OC-12 Multiplexers is referred to as a"0x1" interface. In this case, the DDM-2000 OC-12 Multiplexer feeds the STS-1paths directly from the two rotations of the OC-12 ring to the OC-3 shelf.Protection switching is done on the OC-3 Multiplexer shelf. The remaining functionunits can be equipped with 3DS3, 3STS1E, or OLIU circuit packs as desired.OLIUs can be used for optical extensions as in the OC-12 Multiplexer STS-1 levelpath switched ring for interconnection to additional DDM-2000 OC-3 Multiplexershelves performing VT1.5 level path switching.

Figure 3-11 shows a DDM-2000 OC-12 CO shelf equipped for an STS-3cbroadcast application. This configuration uses a pair of OC-3cs provisioned forvideo. Each OC-3c is split and fed onto different rotations of the ring. There is noprotection switching between the function unit circuit packs (unprotected). Eachdrop (RT) location can be provisioned to drop any or all of the STS-3cs to OC-3 orIS-3 circuit packs. Bandwidth on the ring, not provisioned for this application, canbe used for other path-switched ring applications as shown in the figure with 6DS3s and 3 EC-1s. This configuration also supports Locked STS-3c BroadbandServices.

OC-12 OC-3c Transport Shelf 3
Figure 3-12 shows a DDM-2000 OC-12 shelf equipped for an OC-3c transportapplication. The main application of a shelf, configured in this way, is transport ofvideo or asynchronous transfer mode (ATM) signals. Bandwidth is mapped intoSTS-3c "bundles," and the bundles follow the same path to preserve theisochronous (known, periodic time interval) nature of the transported information.

The fan shelf is required in all DDM-2000 OC-12 Multiplexer applications in acontrolled environment. The fan shelf is not required in OC-12 Regeneratorapplications. All applications should be equipped with a heat baffle as shown inED-8C727-10 for the DDM-2000 OC-12 Multiplexer and OC-12 Regeneratorshelves.
A DDM-2000 Fan Shelf is required for each DDM-2000 OC-12 shelf.
The fan shelf is 3.9 inches high by 9.3 inches deep by 21.2 inches wide andweighs 25 pounds. Mounting brackets can be attached in three positions toaccommodate both front and rear access installations in different bay frames. Thefan shelf is fully accessible from the front for service and maintenance.
When the front cover is removed, the four fan units and a 4-part switch to the leftof center on the front of the shelf are visible (see Figure 3-14). The switchesshould be set as shown in Table 3-3.

The four fan units are independent of each other; any of them can be removed byremoving the connectorized fan cord and the screws that hold the fan unit in theshelf.
A filter must be installed on the bottom of the DDM-2000 OC-12 shelf. The filter issecured by spring clips that hold it in place.
A terminal block is provided for the direct termination of the two −48 V powerfeeders. If direct termination is not needed, optional cable assemblies areavailable (in DDM-2000 OC-12) to connect the power feeders from the DDM-2000bay power cables to the terminal strip on the rear of the fan shelf. A dangler cableprovides an alarm interface so that fan shelf alarms can be reported through anassociated DDM-2000 system. The alarm output is a dry contact closure. It isactivated whenever a fault is detected on the fan shelf and whenever one or both−48 V power feeders fail. Alarm and power cable openings are provided for bothrear and front access installations. A ground stud is provided on the left rear of thefan shelf to meet the UL grounding requirements for rear and front accessapplications. Two ground cables are provided with the fan shelf, one 6-inch cablefor rear access applications and one 18-inch cable for front access applications.To reach the front of the fan shelf, the 18-inch front access ground cable must gothrough the rear cable access opening, through the fan shelf, and exit from theright front cable access opening.

Overview 4
This section describes the power distribution of the DDM-2000 OC-12 Multiplexer.
Introduction 4
The DDM-2000 OC-12 Multiplexer is powered by −48 volts direct current. Thevoltages required to power the circuits within the DDM-2000 OC-12 Multiplexerare generated by DC-to-DC converters mounted on circuit packs within the shelf.
The information in this section is for typical applications only. Refer to Section 10,"Technical Specifications," and 801-525-168, DDM-2000 Floor Plan Data Sheets,and T-82046-30, Power Systems DC Distribution Circuit for Digital TransmissionSystem, for proper engineering of battery plant and feeders for OC-12 Systems.

Power Description 4
Two independent −48 volt office power feeders (A and B) enter the shelf throughbackplane connectors and are fused and filtered at the user panel, thendistributed to the circuit packs. Power conversion is performed through modularpower converters located on the circuit packs. In each circuit pack, the twofeeders are diode ORed, fused, filtered, and regulated by the board-mountedpower modules. This provides the required redundancy in case of the loss of onefeeder or one fuse. Figure 4-1 shows which circuit packs have convertersmounted on the printed wiring boards. Power modules are located on the OLIU,3DS3, 3STS1E, TSI, TG, SYSCTL, and OHCTL circuit packs.

Circuit Packs 4
OLIU Circuit Packs 4
The 21D/21D-U OLIU circuit pack is powered by a −48 volt to +5 volt DC-to-DCconverter mounted on the circuit pack. The backplane power feeders supply Aand B −48 volts to this converter via diode ORed circuits and fuses mounted onthe circuit pack.
The 21G/21G-U OLIU circuit pack is powered by two DC-to-DC converterslocated on the circuit pack. The backplane power feeders supply A and B −48volts to these converters via diode ORed circuits and fuses mounted on the circuitpack. One converter supplies +5 volts and one supplies −5.2 volts for the circuitpack.
The 23G/23G-U and 23H/23H-U OLIU circuit packs are powered by four DC-to-DC converters located on the circuit packs. The backplane power feeders supplyA and B −48 volts to these converters via diode ORed circuits and fuses mountedon the circuit packs. One converter supplies +5 volts, one supplies −5.2 volts, onesupplies −2.3 volts, and one supplies +15 volts for the circuit packs.
TSI, TGS/TG3, 3DS3, and 3STS1E Circuit Packs 4
The BCP3 TSI, BBF2B/BBF4 TGS/TG3, 3DS3, and 3STS1E circuit packs arepowered by a −48 volt to +5 volt DC-to-DC converter mounted on each circuitpack. The backplane power feeders supply A and B −48 volts to this converter viadiode ORed circuits and fuses mounted on the circuit pack. The converterprovides +5 volts DC power for TSI, TGS/TG3, 3DS3 and 3STS1E circuit packs.
Control Circuit Packs 4
The SYSCTL and OHCTL circuit packs are each powered by a −48 volt to +5 voltDC-to-DC converter located on the pack. The backplane power feeders supply Aand B −48 volts to these converters via diode ORed circuits and fuses mounted onthe circuit packs.

LEDs 4
Two green power on (PWR ON A and PWR ON B) LEDs on the Group 4 shelfuser panel indicates that the shelf is receiving fused −48 volt power. The LEDs willremain illuminated as long as either −48 volt feeder is supplying power to theshelf.
Normally the FAULT LED on the circuit pack faceplates is operated via thecontroller which provides a ground return for current generated by the on-boardconverter. In the event of a DC-to-DC converter failure, the LED will be operatedvia the −48 volt power leads. The −48 volt power leads are supplied through anelectronic gate or relay contact normally held open by the converter. The power,fusing, and LED circuits shown in Figure 4-2 are used on all circuit packs with on-board DC-to-DC converters.

Overview 5
This section describes the DDM-2000 OC-12 Multiplexer transmission andsynchronization interfaces.
Transmission Interfaces 5
The DDM-2000 OC-12 Multiplexer supports DS3, OC-3, EC-1, and OC-3c low-speed interfaces and an OC-12 high-speed interface at both 1310 nm and 1550nm wavelengths. The DDM-2000 OC-12 Multiplexer provides four low-speedfunction units (FN). Each can be equipped with:
■ BBG11/BBG11B 3DS3 circuit packs (1x1 protected)
■ BBG12 3STS1E circuit packs (1x1 protected)
■ 21D/21D-U OLIU circuit packs (1+1 or 0x1 protected or STS-3c broadcastvideo)
■ 21G/21G-U/21G2-U OLIU circuit packs (1+1 or 0x1 protected or STS-3cbroadcast video).
The 3DS3, 3STS1E, 21D/21D-U OLIU, and 21G/21G-U/21G2-U OLIU circuitpacks can be mixed in any combination across the four function units to providefor termination/transport of 12 STS-1 signals or 4 concatenated STS-3c (OC-3c)signals. The DS3 interfaces accept any DSX-3 compatible clear channel signal.

Table 5-1 summarizes the DDM-2000 OC-12 Multiplexer transmission interfacesfor the current software release.
OC-12 STS-1 Path Switched Ring 5
Figure 5-1 is an overall block diagram of a DDM-2000 OC-12 Multiplexer STS-1/VT1.5 path switched ring node. The DDM-2000 OC-12 Multiplexer ring supportsDS3 and EC-1 low-speed interfaces in an STS-1 path switched ring configuration,0x1 OC-3/IS-3 interfaces in an STS-1/VT1.5 path switched ring configuration, andoptical extensions with OC-3/IS-3 or OC-3c/IS-3c interfaces. The time slotinterchange (TSI) feature provides full flexibility in assigning signals between low-speed DS3, OC-3/OC-3c/IS-3/IS-3c, and EC-1 ports and the high-speedinterface. Each function unit can handle a maximum of 3 STS-1s for a total of 12STS-1s or one STS-3c for a total of 4 STS-3cs.

Dual Ring Interworking (DRI) 5
The DDM-2000 OC-12 Multiplexer STS-1/STS-3c DRI application uses the sameshelf configuration as the DDM-2000 OC-12 Multiplexer path switched ring(Figure 5-1). In this configuration, the DDM-2000 OC-12 Multiplexer can provideSTS-1 DRI with another DDM-2000 OC-12 ring, a DDM-2000 OC-3 ring, or anFT-2000 OC-48 Lightwave System ring with redundant signal appearances at thetwo central offices via EC-1/OC-3/OC-3c/IS-3/IS-3c and DS3 interfaces (seeFigure 9-8 in Section 9 "Maintenance Description"). STS-1 paths are provisionedfor drop and continue at the interconnecting nodes, and path selection is at theSTS-1 level. When used with the DDM-2000 OC-3 Multiplexer, the DDM-2000OC-12 Multiplexer STS-1/VT1.5 (0x1) DRI application can be created with thedrop and continue feature implemented in the DDM-2000 OC- 3 Multiplexer shelf.The DDM-2000 path switched ring architecture allows mixing of drop and continuecircuits with standard path switched circuits.
OC-3/OC-12 Ring (0x1) Low-Speed Interfaces 5
The DDM-2000 OC-12 ring supports (0x1) OC-3/IS-3 interfaces in its function unitslots. These interfaces must be provisioned as 0x1 and are supported in singlehoming and dual homing configurations (see Figure 5-2 and Figure 5-3respectively). For single homing, signals pass through the DDM-2000 OC-12transport ring and exit to the DDM-2000 OC-3 ring. OC-12 function unit slot FN(x)-1 is connected to OC-3 main-1 and OC-12 FN slot FN(x)-2 is connected to OC-3main-2. Switching is not done on the DDM- 2000 OC-12 Multiplexer on theselines, or paths on these lines; rather VT1.5 or STS-1 level path switching is doneon the DDM-2000 OC-3 Multiplexer. This allows DDM-2000 OC-3 nodes runningring software to interface with DDM-2000 nodes of an OC-12 ring in such a way asto provide ring-on-ring architecture. Each OC-3 ring so supported occupies up tothree STS-1 time slots on the OC-12 ring. Each OC-12 node can provision thesame STS-1 time slots as other OC-12 nodes to drop to the OC-3 shelf (to shareSTS-1s among several OC-3 shelves), or the OC-12 node can provision differentSTS-1s at different sites. The OC-12 ring passes the contents of these STS-1time slots between the low-speed OC-3/IS-3 lines and OC-12 high-speed lineswithout terminating them or performing any path protection switching on them. Upto four OC-3 rings can be supported in this fashion by an OC-12 ring to maximizethe OC-12 bandwidth utilization. This allows access to any and all VT1.5 signalsat an OC-12 site.
The OC-3/IS-3 lines between an OC-12 node and an OC-3 node connected in aring (0x1) fashion behave like the OC-3 lines between the nodes on an OC-3 ringand do not perform line level protection switching. Instead, the OC-3 shelvesperform the normal path protection switching functions.

See Figure 5-3. For dual homed 0x1 ring applications, one function unit slot on theOC-12 shelf must be empty. When the OC-12 shelf is provisioned for 0x1 (default)operation, incoming Ring 1 (incoming to main B-1) always feeds (is locked to)function unit ( )-1 and, therefore, main-1 of the OC-3 shelf. Similarly, incomingRing 2 (incoming to main B-2) always feeds (is locked to) FunctionUnit ( )-2 and, therefore, main-2 of the OC-3 shelf.
Similarly, the TSI on the OC-12 shelf are locked so that Ring 1 output is always fedfrom function unit ( )-2, and Ring 2 output is always fed from function unit ( )-1.The Ring 1 input is always received on main B-1, and the Ring 2 input is alwaysreceived on main B-2.
When STS-1s are dropped to a 0x1 function unit, any fiber failure detected ateither the OC-3 shelf or OC-12 shelf will cause the OC-3 shelf to select all trafficfrom the other ring.

Linear (1+1) Optical Extension Between OC-12and OC-3 5
See Figure 5-4 and Figure 5-5. The function units in the DDM-2000 OC-12 shelfcan contain linear (1+1) protected OC-3/IS-3 circuit packs. This allows aDDM-2000 OC-12 shelf to connect to the main slots of a DDM-2000 OC-3 shelf.This allows more options in designing a DDM-2000 network, such as adding aDDM-2000 OC-3 shelf off of a DDM-2000 OC-12 ring. In the transmit direction, acircuit pack failure will cause a switch. In the receive direction, an incoming STSsignal failure or circuit pack failure will cause a switch.

Synchronization Interfaces 5
Each DDM-2000 OC-12 Multiplexer can be provisioned to one of three timing modes:
■ Free-running from an internal oscillator
■ Line timing from an incoming optical interface. This timing reference is used togenerate all outgoing signals. Line timing is an intermediate node that derivestiming from the incoming fiber. Loop timing is a special case of line-timing andis the terminating node that derives timing from the incoming fiber.
■ External timing from the digital synchronization network via DS1 references(DS1 External).
The terms loop timing and line-timing have been changed to clarify timingterminology. When the OLIU derives local shelf timing from the incomingoptical signal and the shelf is an intermediate shelf (choice of OC-N lines fortiming) in a linear network for example, it is called line-timing. Loop timing is asubset of line-timing used to describe the timing mode of the terminating node(single source of timing) of a linear network, for example.
NOTE:The synchronization and timing examples used throughout this chapterreference the timing generators as “TG.” This could represent either the BBF2BTGS or the stratum 3 BBF4 TG3.
Free-Running 5
For free-running operation, the TG derives timing from a temperature-compensated,voltage-controlled crystal oscillator (TCVCXO) and a digital phase-locked loop(DPLL) with a full temperature range end-of-life accuracy of ±15 parts-per-million(ppm) for the BBF2B TGS, and ±4.6 ppm for the BBF4 TG3.
Line Timing 5
The reference signal feeding the phase-locked loop (PLL) is selected from theinternal oscillator or a line-timing clock derived from the incoming optical line. In line-timing mode, the OC-12 line being selected for transmission is also selected as thetiming reference.
DS1 External 5
Each TG circuit pack receives one DS1 reference signal which it monitors and fromwhich it recovers a clock signal. The recovered clock is cross-fed to its companion TGcircuit pack in the same shelf. If the microprocessor on one TG circuit pack detects anincoming DS1 reference failure, it will signal the microprocessor on the companionTG circuit pack.
363-206-295Transmission and Synchronization Interfaces
Issue 1 December 1997 5-11
Thus, each TG circuit pack has two DS1 references to choose from, one which isinput directly and the other cross-fed. Both TG circuit packs will normally selectthe same DS1 input. A loss of both DS1 references results in the TG circuit packentering holdover mode.
Holdover 5
The TG circuit pack has an internal TCVCXO that maintains shelf timing within± 4.6 ppm (BBF2B TGS) or ± 0.37 ppm (BBF4 TG3) for 24 hours in the event of anunprotected timing DS1 reference failure.
DS1 Output Modes: MULT and SYNC OUT 5
The DDM-2000 supports two DS1 output modes: MULT and SYNC OUT. Bothmodes are used in conjunction with external synchronization modes but only onemay be supported on a single shelf.
DS1 Output Mode, MULT 5
In a CO environment where multiple DDM-2000 Multiplexers are installed in anetwork bay frame, a single pair of DS1 timing references from the buildingintegrated timing supply (BITS) can be used to externally synchronize all shelvesin a bay. This unique feature reduces the number of BITS output ports required toexternally synchronize multiple DDM-2000s, thus minimizing network costs.
Each DDM-2000 provides two sets of DS1 input and output ports, one set per TGcircuit pack. A DS1 timing reference is initially connected to the bottom shelf in thebay (shelf 1) and each TG terminates and actively buffers this timing reference.The reference is then used as a synchronization reference for that shelf. Thebuffered signal is also output from each TG as a DSX level (with adjustableequalization). (The TG does not retime or influence the DS1 output when in theholdover mode.) This DS1 output is then connected to the DS1 input port of thenext DDM-2000 in the bay via a special (MULT) cable forming a MULT chain. See363-206-200, DDM-2000 Multiplexer Applications, Planning, and Ordering Guide,for cabling information.
If a TG in the MULT chain is removed, shorting contacts in the backplane willredirect input and output signals so the subsequent shelves continue to receivevalid DS1 signals. However, if a BBF2B/BBF4 provisioned for SYNC OUT isinserted in the MULT chain, the traceability of the DS1 output will be affected. Thiscould result in untraceable timing or the creation of timing loops. To ensure thatreplacement circuit packs are provisioned correctly, the DDM-2000 software willmonitor newly inserted packs for the correct “shelf provisioning.” If a newlyinserted pack does not match the shelf provisioning, the fault LED is lit on thatpack and indicates that a provisioning error has occurred. It is always best toverify TG provisioning before insertion.

5-12 Issue 1 December 1997
DS1 Output Mode, SYNC OUT 5
In a CO environment, it may be necessary to externally synchronize a BITS to aSONET reference with traceability to a primary reference source (PRS). Whenoptioned for SYNC OUT the DDM-2000 will output a derived DS1 traceable to aselected OC-12 input. The frequency of the optical line is divided down to a 1.544MHz signal and used to create the derived DS1.
When using SYNC OUT, two input timing modes are available: DS1 external-timing or line-timing. These timing modes will only influence the synchronizationsource used for the derived DS1. In SYNC OUT mode the DDM-2000 uses anexternal DS1 reference for synchronization This external reference typicallycomes from a BITS. In line-timing SYNC OUT mode, the DDM-2000 will use aselected optical reference for synchronization. The derived DS1 is carried to theBITS by a special SYNC OUT cable which is capable of externally timing theDDM-2000 if the DS1 external SYNC OUT mode is selected. See 363-206-200,DDM-2000 Multiplexer Applications, Planning, and Ordering Guide, for cablinginformation.
If a TG provisioned for MULT is inserted into a DDM-2000 provisioned for SYNCOUT the traceability of the DS1 output will be altered. This could result inuntraceable timing or the creation of timing loops. To ensure that replacementpacks are provisioned correctly, the DDM-2000 software monitors newly insertedpacks for the correct “shelf provisioning.” If a newly inserted pack does not matchthe shelf provisioning, the fault LED is lit on that pack and indicates that aprovisioning error has occurred. It is always best to verify TG provisioning beforeinsertion.
The free-running, line-timing, and DS1 external timing modes can be combinedinto various subnetwork configurations, some of which are shown in Figure 5-6.The figures show basic single span configurations. In more complex subnetworkssuch as hubbing, these basic span configurations are duplicated and/or mixed,depending on the application, to produce a subnetwork synchronizationconfiguration.

Figure 5-6a shows the CO system is internally timed (free-running). At the remoteterminal (RT), the TG derives its timing from the incoming optical signal and usesit to time itself and loop timing back to the CO.
Figure 5-6b and Figure 5-6c show the CO timed from an external stratum 3 orbetter source. The RT derives its timing from the incoming optical line and cansend a DS1 output to a BITS clock.
The external timing configuration (Figure 5-6d) uses external DS1 timing to eachDDM-2000 Multiplexer in the network. Since this configuration requires local officeclocks at each site, it is most suited to interoffice applications. A DDM-2000network may have all DS1 references traceable to a primary reference source(synchronous operation) or multiple primary reference sources (plesiochronousoperation).
The PRS is equipment that provides a timing signal whose long-term accuracy ismaintained at 10-11 or better with verification to universal coordinated time (timeand frequency standard maintained by the U. S. National Institute of Standardsand Technology), and whose timing signal is used as the basis of reference for thecontrol of other clocks in a network.
An interoffice ring should have each node externally timed if BITS clocks areavailable. All other rings should have one node externally timed (two in some dualhoming configurations) and the rest of the nodes line timed. See 363-206-200,DDM-2000 Multiplexer Applications, Planning, and Ordering Guide, for moresynchronization information.

Synchronization Messaging 5
SONET synchronization messaging is used to communicate the quality ofsubnetwork timing, internal timing status, and timing states throughout asubnetwork. Transitions to and from holdover or between OC-12 references, forshelf timing, and to and from DS1 AIS, for the DS1 output, are based onsynchronization messages received over the OC-12 line from which theDDM-2000 system is extracting timing. In ring networks with synchronizationmessaging, either TG circuit pack allows line-timing and automatic switching fromeither of the two ring optical interfaces.
The DDM-2000 Multiplexers provide a synchronization messaging feature toensure the integrity of network synchronization during both normal and abnormalconditions. Through the use of synchronization messaging, the current quality ofthe timing source can be conveyed from one DDM-2000 Multiplexer to the next.This capability allows the DDM-2000 Multiplexers to automatically change theirtiming reference in order to always maintain the highest quality timing available.The capability also allows the DDM-2000 Multiplexers to inform a local BITS clockwhen the DS1 timing output has been degraded and should no longer be used asa reference. This synchronization messaging feature is based on the schemedeveloped in the American National Standards Institute (ANSI) T1X1 standardscommittee.
Applications 5
The applications that are currently supported with the synchronization messagingfeature can be divided into three categories:
1. DS1 Timing Output Integrity
2. Automatic Synchronization Reconfiguration
3. Synchronization Provisioning Integrity.

Issue 1 December 1997 5-17
DS1 Timing Output Integrity 5
The DS1 timing outputs are typically used to distribute timing from the BITS clockin one office (master) to the BITS clock in the next office (slave), using the SONETtransmission facilities between them as the synchronization vehicle. The BITS aretypically of stratum 2 or stratum 3 accuracy. The DDM-2000 Multiplexer does notintroduce its own internal timing source onto the SONET facility but merelytransfers the quality of its timing reference. This ability preserves the requiredhierarchical structure of the timing network and should be maintained at all times.
If the DDM-2000 Multiplexer at the master office enters holdover due to adisconnected reference cable or a local BITS failure, the quality of the DS1 timingoutput at the slave office will now be traceable directly to the DDM-2000Multiplexer. If the master DDM-2000 system contains a TG3 circuit pack, stratum3 accuracy will be maintained indefinitely. This provides acceptable timing forstratum 3 NEs at slave offices. If the master DDM-2000 contains a TGS circuitpack, stratum 3 accuracy will be maintained for the first 24 hours of holdover. Afterthe first 24 hours, the DDM-2000 system could exceed stratum 3 accuracy.
If a DDM-2000 system contains a TGS pack, it may change the output of itsderived DS1 under some conditions. If the incoming synchronization message isbetter than internal clock (IC) the derived DS1 will be an ‘all ones’ with framing.This format is suitable for providing synchronization to a BITS of stratum 3accuracy. If the co-located DDM-2000 enters holdover or the incomingsynchronization message is IC or worse, the derived DS1 format will change to ‘allones’ without framing (AIS). This will prevent a BITS from using this input andforce the BITS to either select a new input or enter holdover. This change to AISpreserves the stratum timing hierarchy by allowing the BITS to synchronize from aclock of equal or higher quality.
Available in R5.1 and later is the threshold AIS feature. This feature allows theuser to select the value of the incoming message that causes the derived DS1output to output AIS. This feature will allow stratum 2 BITS clock to receive timingfrom a TGS or TG3 without violating stratum timing rules.

As shown in Figure 5-7a (Figure 5-7 is an OC-3 linear application used to explainthe concepts of synchronization messaging.), SONET synchronization messagingnotifies the DDM-2000 Multiplexer at the slave site to place alarm indication signal(AIS) on the DS1 timing output. This BITS can then enter holdover or switch to analternate reference.

Automatic Synchronization Reconfiguration 5
SONET was designed to operate optimally in a synchronous environment.Although plesiochronous and asynchronous operation can be supported throughthe use of pointer adjustments, transmission quality is affected by the generationof additional jitter and wander due to pointer adjustments. Because of this, it isdesirable to maintain synchronous operation whenever possible.
Through the use of synchronization messages, the quality of the different timingreferences can be made available at each DDM-2000 Multiplexer. The DDM-2000OC-12 Multiplexer shelf can always determine the best timing reference availableto it and switch to it. Through this mechanism, the synchronous operation of thesubnetwork can be maintained. The switching of timing references is hitless, andthe synchronization messages also allow it to be done without creating timingloops in the process. Note that automatic synchronization reconfiguration appliesonly to switching between available and line-timing references and not betweentiming modes. For example, switching between line-timed to external timed orexternal timed to line-timed would not be supported.
In the linear dual-homing network in Figure 5-7, normal operation includes anexternal timing reference at each of the COs. The RT sites are each loop timedfrom the CO DDM-2000 Multiplexers on the left. If a fiber failure occurs betweenthe first two DDM-2000 Multiplexers, the automatic synchronizationreconfiguration feature will cause the loop timed DDM-2000 Multiplexers tochange their direction of loop timing. This prevents any DDM-2000 Multiplexerfrom operating in holdover for an extended period of time.
363-206-295Transmission and Synchronization Interfaces
5-20 Issue 1 December 1997
Consider the access ring network in Figure 5-8. Under normal operation, the ringhas one DDM-2000 Multiplexer externally timed and the others line-timed in thecounterclockwise direction. If a fiber failure occurs between the first twoDDM-2000 Multiplexers, the automatic synchronization reconfiguration feature willcause the DDM-2000 Multiplexers to change their line-timed directions toclockwise. The result is that the ring is again operating synchronously. The ringalready provides self-healing restoration of the traffic, so it is especially importantto maintain synchronous operation during this type of failure to prevent servicedegradation due to increased jitter and wander.

Synchronization Provisioning Integrity 5
A welcome side feature of synchronization messaging is that it helps preventprovisioning errors. Provisioned timing loops on the DDM-2000 Multiplexers will bequickly detected through the synchronization messaging algorithm and preventedby forcing a shelf into holdover. The system can then be reprovisioned correctly.
Feature Details and Options 5
As mentioned previously, SONET synchronization messaging is used tocommunicate the quality of the subnetwork timing throughout the subnetwork. Thisis done using bits 1-3 of the K2 byte found in the SONET overhead. In OC-12Release 5.1 and later releases, synchronization messaging can also be done usingbits 5-8 of the S1 byte in the SONET overhead. If a DDM-2000 OC-12 system isderiving timing from a given OC-N interface, and synchronization messaging isenabled on that interface (Kbyte messages and Sbyte messages in OC-12 Release5.1 and later are provisioned using the set-ocn command), the system interpretsthe received message to determine its internal timing status. The system alsodetermines the state of the DS1 output, if the DS1 output is enabled. TheDDM-2000 OC-12 system also transmits over the particular OC-N interface and allother OC-N interfaces that are enabled for synchronization messaging, theappropriate message indicating the quality of its timing and its active timing mode.Table 5-3 and Table 5-4 list the associated internal timing status and DS1 Outputstates that are associated with synchronization messages received from the OC-Ninterface when synchronization messaging is enabled. The tables lists themessages from low to high quality.

Table 5-4. Synchronization Messages using S1 Byte *
Synchronization messaging using the SONET K2 byte and S1 byte can bedisabled on a per OC-N interface using the set-ocn command (not supported byOC-1). Zeros will be transmitted on bits 1-3 of the K2 byte if this is done; all oneswill be transmitted on bits 5-8 of the S1 byte if this is done. The timing andsynchronization status of a shelf can be determined using the rtrv-synccommand.
The "Don't Use" message is sent when the system determines that its timing isnot suitable for synchronization; for example, due to failure.
When the DDM-2000 OC-12 system is configured for external timing and its DS1output port is provisioned for MULT mode, the message Sync Quality Unknown(SQU) for K byte, or Sync Trace Unknown (STU) for S byte, is sent on all the OC-Ninterfaces where synchronization messaging is provisioned. When the capabilityof communicating with a BITS clock over the DS1 overhead exists, the quality ofthe reference signal will be transmitted instead; for example, Stratum 1.
When the DDM-2000 OC-12 system is configured for external timing and its DS1output port is provisioned for SYNC OUT mode, the Timing Looped Back (TLB)message for K byte, or “Don’t Use” message for S byte, will be sent on the OC-Ninterfaces towards the network element (NE) from which the DS1 timing output isbeing derived. The SQU message for K byte, or STU for S byte, will be sent on allother OC-N interfaces where synchronization messaging is provisioned. If theDS1 output is generating AIS while the system is configured in this way, the

message SQU for K byte, or STU for S byte, will be transmitted on all OC-Ninterfaces.
When the DDM-2000 OC-12 system is configured for free-run or is in holdovermode, the Internal Clock message for K byte, or Traceable SONET minimum Clkfor S byte, will be sent on all OC-N interfaces where synchronization messaging isprovisioned.
When the DDM-2000 OC-12 system is configured for line timing, the TLBmessage for K byte, and “Don’t Use” for S byte, will be sent on the OC-Ninterfaces towards the NE from which the timing is being derived. The messagereceived on the OC-N interface will be sent on all other OC-N interfaces wheresynchronization messaging is provisioned.
With automatic synchronization reconfiguration, the DDM-2000 Multiplexersystems use and compare the incoming synchronization messages on the OC-Ninterfaces available for line-timing to select the highest quality synchronizationreference available. If the received quality levels are the same on the referencesavailable for timing, the existing line timing reference takes precedence. Thisfeature guarantees the nonrevertive operation of reconfiguration. The line-timingreference is provisioned by the set-sync command. Table 5-3 lists thesynchronization messages in ascending order.
The existence of automatic synchronization reconfiguration does not change thesystem's behavior on traditional line failures; for example, loss of frame (LOF),loss of signal (LOS), and others.
There are synchronization references in the DDM-2000 system that can beprovisioned as network timing sources but are not considered as timing sourcesfor automatic synchronization reconfiguration. Examples of these are the linearextensions off of a DDM-2000 ring. This type of interface is considered a linearinterface, and the system treats it as such with regards to synchronization.
Table 5-5 lists the synchronization references available on DDM-2000 OC-3 andOC-12 system topologies.

For DDM-2000 OC-3, function unit C, when equipped with an OC-3/IS-3 OLIU,can be selected as an option for automatic synchronization reconfiguration. Thisis useful in DRI networks where an OC-3 ring is connected through an OC-3/IS-3optical interface to an OC-12 or FT-2000 OC-48 Lightwave System ring.
In OC-12 Release 5.1 and later ring releases, the sending of DS1 AIS on theoutput of the BBF2B/BBF4 circuit pack can be provisioned by using the set-sync command. Depending on the quality level of the incoming sync messages,this new parameter can be provisioned to send DS1 AIS upon receiving level 5(default), level 4, level 3, or level 2. Refer to Table 5-3 and Table 5-4 for definitionsof quality levels. AIS will be sent as long as the received message is at theprovisioned or greater in quality level number.
Examples 5
In this part, some detailed examples are given to show specifically how thesynchronization messages propagate through the DDM-2000 network and assistin the recovery from a fiber failure. Through these examples, one can extend thesame concept to any other network that may include different topologies, numberof sites, failure locations, and number of BITS clocks.
NOTE:All nodes in a ring using automatic synchronization reconfiguration musthave the synchronization messaging and automatic synchronizationreconfiguration features enabled to prevent alarms.
In all of the following examples, if the sync message parameter within theset-oc3 or set-oc12 commands has been provisioned to “S byte” for an opticalinterface, then the equivalent quality level S byte message will be transmitted fromthat optical interface. The following are equivalent messages:
K2: Sync Quality Unknown is the same as, S1: Sync Trace Unknown
K2: Timing Looped Back is the same as, S1: Don’t Use
K2: Internal Clock is the same as, S1: Traceable SONET minimum Clock
K2: Stratum 3 is the same as, S1: Traceable Stratum 3.
Synchronization Reconfiguration Using an Externally Timed AccessRing 5
Figure 5-9a shows an externally timed access ring operating in its normalconfiguration. The DDM-2000 OC-3/OC-12 Multiplexer at the CO (Site A) isexternally timed from a BITS clock referenced to a PRS traceable source (hostnode). The remaining DDM-2000 OC-3/OC-12 Multiplexers are externally timedfrom a BITS clock referenced to a derived DS1.
363-206-295Transmission and Synchronization Interfaces
Issue 1 December 1997 5-25
The sync quality unknown (SQU) message is sent to indicate where timing istraceable to an external BITS and where it is valid to be used. Automaticsynchronization reconfiguration is not an option for externally timed DDM-2000OC-3/OC-12 Multiplexers; therefore, a change in the synchronization messagewill not cause an automatic synchronization reconfiguration.
The stratum level of the BITS clock at the CO (Site A) must be equal to or better(more accurate) than the stratum level of the BITS clocks used at the other sites.This is necessary to maintain the stratum level hierarchy.

In Figure 5-9b, a fiber has been cut between sites A and B. Immediately theDDM-2000 OC-3/OC-12 Multiplexer at site B changes the format of its derivedDS1 to AIS. This forces the BITS clock at site B to enter holdover or switch inputsource (if a valid one is available). Because automatic synchronizationreconfiguration is not available, the synchronization status messages are notused. All other non-host nodes will track the holdover clock at site B. Although notiming loops have been formed, the timing of all non-host nodes will differ from thehost node by the accuracy of the holdover clock at site B.

Figure 5-10a shows the access ring operating in its normal configuration. TheDDM-2000 Multiplexer at the CO is externally timed, and each of the otherDDM-2000 Multiplexers are line timed in a counterclockwise direction. The SQUmessage is sent to indicate where timing is traceable to an external BITS andwhere it is valid to be used. The timing looped back (TLB) message is sent on theinterface that is being used as the line-timing reference because a timing loopwould be created if this timing reference were used. Synchronization messagingand automatic synchronization have both been enabled for this network.
In Figure 5-10b, a fiber has been cut between sites A and B. Immediately, theDDM-2000 Multiplexer at site B enters holdover and sends out the internal clock(IC) message to site C. The DDM-2000 Multiplexer at site B cannot switch to linetime from site C because it is receiving the TLB message on that interface.

In Figure 5-10c, the DDM-2000 Multiplexer at site C detects the incoming ICmessage and sends out the IC message to site D. The DDM-2000 Multiplexer atsite C cannot switch to line time from the other rotation because it is receiving theTLB message on that interface and continues to derive timing from Site B.
In Figure 5-10d, the DDM-2000 Multiplexer at site D detects the incoming ICmessage. Because this DDM-2000 Multiplexer is receiving the SQU messagefrom site A, it will switch to line time from site A because SQU is higher qualitythan IC. After the switch occurs, the TLB message is sent back to site A and theSQU message is retransmitted to site C.

In Figure 5-10e, the DDM-2000 Multiplexer at site C detects the incoming SQUmessage from site D. The SQU message is a better quality message than the ICmessage being received from site B, so the DDM-2000 Multiplexer at site Cswitches to line time from site D. After the switch occurs, the TLB message is sentback to site D, and the SQU message is retransmitted to site B.
In Figure 5-10f, the DDM-2000 Multiplexer at site B detects the incoming SQUmessage from site C. The SQU message is a better quality message than theinternal holdover capability, so the DDM-2000 Multiplexer at site B switches to linetime from site C. After the switch occurs, the TLB message is sent back to site C,and the SQU message is forwarded to site A.
When the failure clears, the current synchronization arrangement remains in thenew configuration unless it is manually switched back or another failure causes itto switch back (nonrevertive operation).

Network Timing Distribution 5
DS1 signals have long been used to pass timing information through the networksynchronization hierarchy. These DS1 timing references should be transmittedbetween master and slave clock sources over the most reliable facilities available.In some cases, these DS1 signals also carry traffic. The facility of choice hasevolved from T-carrier through asynchronous lightwave systems to SONETlightwave systems. As these systems are upgraded to SONET systems, timingdistribution plans should be revisited to ensure the quality of the timing signals arenot degraded. With proper planning, SONET can be used to improve the overallquality of the network timing.
Interoffice Timing Distribution 5
One way SONET can be used to improve the quality of interoffice network timingis through the use of OC-N timing distribution. DDM-2000 supports the evolutionto interoffice OC-N timing distribution by providing a DS1 timing output derivedfrom the incoming OC-N signal. The DS1 timing output is traceable to the clocksource that times the DDM-2000 subnetwork and has extremely low jitter andwander. This is true regardless of the number of DDM-2000 systems connected inthe network. This DS1 can be fed to the local BITS clock which subsequentlytimes the local DDM-2000 and the other equipment in the office. If a BITS clock isnot available in the office, the DS1 timing output can be used to time otherequipment (including another DDM-2000) directly. DDM-2000 can provide DS1timing outputs in all supported topologies (for example, point-to-point, add/drop,and ring).
363-206-295Transmission and Synchronization Interfaces
Issue 1 December 1997 5-31
With OC-N timing distribution, the OC-N line signal, rather than a DS1 multiplexedinto the SONET payload, will provide a timing transport mechanism better suitedto a complex, heavily interconnected SONET network. In this configuration, a DS1reference from the CO BITS clock still times the OC-N transmitted to the remotesite; at the remote site, a DS1 output reference is created directly from thereceived OC-N signal (Figure 5-11).
The stratum level of the BITS clock at the CO must be equal to or better (moreaccurate) than the stratum level of the BITS clocks used at the other RT sites. Thisis necessary to maintain the stratum level hierarchy.

OC-N timing distribution has several potential advantages. It preserves transportbandwidth for customer services and guarantees a high-quality timing signal.Also, as the CO architecture evolves to replace DSX interconnects with SONETEC-1 and IS-3 interconnects and direct OC-N interfaces, OC-N distributionbecomes more efficient than multiplexing DS1 references into an access facility inthe CO.
A previous drawback to using OC-N timing distribution was that network timingfailures could not be communicated to downstream clocks via DS1 AIS, since theDS1 signal does not pass over the OC-N interface. With synchronizationmessaging, clock stratum levels can be passed from NE to NE, allowingdownstream clocks to switch timing references without creating timing loops, if anetwork synchronization failure occurs. If a quality timing reference is no longeravailable, the DDM-2000 sends AIS over the DS1 interface. If the local OC-N linesfail, DDM-2000 outputs AIS on the DS1 output or an upstream DDM-2000 systementers holdover.
Access Network Timing Distribution 5
OC-N timing distribution can also be used in access networks or to small COs. Inthis configuration, a DS1 reference from the CO BITS clock still times the OC-Ntransmitted to the remote site. The line-timing capability of the DDM-2000provides the ability to recover OC-N timing. The DS1 timing output feature can beused to also extend timing to customer networks or remote sites. In this case, theDS1 timing output can be used to time switch remotes, DDM-2000 shelves, orother local equipment directly. Ideally, the equipment can provide an externaltiming reference. Otherwise, the signal must be input to a traffic DS1 port on theexternal equipment which will tie up some of this equipment's bandwidth. In thisconfiguration, it is important that the DS1 reference to the DDM-2000 in the CO betraceable to the same clock used to source the DS1s being carried to thecustomer site or small CO. If it is not, slips may occur.
Although an ideal source of timing, OC-N timing distribution, that is, via a DS1timing output, cannot be used to provide timing in all applications. In cases wherethe local equipment is not provided with an external timing reference input, or insome private networks where the timing is to be distributed from another privatenetwork location, timing will continue to be distributed via traffic-carrying DS1s. Inthese applications, a stable DS1 timing source can be achieved by ensuring thatall elements in the SONET network are directly traceable to a single master clockvia line-timing. In this environment, the high-performance desynchronizer designof the DDM-2000 Multiplexer allows a DS1 timing reference to be carried as amultiplexed DS1 payload.

Issue 1 December 1997 5-33
It is recommended that, where possible, the DS1 sources (switch, PBX, or otherequipment) be traceable to the same timing source used to time the DDM-2000SONET network. Multiplexed DS1 reference transport is also consistent withcurrent planning and administration methods. Applications include passingsynchronization from the public switched network to a PBX-based private network(Figure 5-12) and synchronizing an end-office remote switch to a larger office'shost switch.

Craft Interface Terminals (CIT) 6
The DDM-2000 OC-12 Multiplexer supports three types of access mechanismsthrough the CIT that can be supported simultaneously.
■ Local access
■ Remote access via a modem port
■ Remote access via the data communications channel (DCC).
A CIT is recommended for installation, maintenance, and administrative activities.The CIT can be either an RS-232-D terminal or personal computer (PC). AnMS-DOS * PC is required for software download and to run CPro-2000 software.Any PC may function as a CIT when loaded with a commercially-availableterminal emulation program. See Section 10, "Technical Specifications," for PCspecifications.
Table 6-1 lists some of the terminals and PCs that can be used with the CITinterface. Note that some terminals and PCs may no longer be commerciallyavailable but can still be used.

Local Access 6
Figure 6-1 shows the system has two EIA-232-D compatible interfaces for a CIT.The front access interface is configured as data communications equipment(DCE) for direct CIT access (CIT 1). The rear access CIT interface (CIT 2) isconfigured as data terminal equipment (DTE) to allow a permanent modemconnection without requiring a null modem. However, a null modem is requiredwhen connecting a CIT directly to the rear access DTE interface. CIT access via amodem connection is identical to local CIT access.

In a bay multiple CIT cabling arrangement, connecting a CIT to any shelf in thebay provides CIT access to that DDM-2000 shelf and any other DDM-2000 OC-3or OC-12 Multiplexer shelf in that bay. The shelf is selected by using the shelf IDlogin. In this arrangement, only one front and one rear CIT access can be used.Also with this arrangement, access to shelves in multiple subnetworks can beachieved from the same physical interface. A subnetwork consists of all shelvesinterconnected with the SONET DCC over OC-N interfaces.
For example, with 6 shelves per bay and 8 bays in a subnetwork, access to 48shelves is achieved with a single physical interface.
Using a PC as a CIT 6
In addition to CIT functions, a PC is required for software downloads andfacilitates software program updates. Any MS-DOS PC can be used to emulate atraditional CIT through a variety of low-cost terminal emulator software packages;thus, an MS-DOS PC can serve DDM-2000 OC-12 Multiplexer needs veryefficiently. In addition, the DDM-2000 OC-12 Multiplexer user interface can beaccessed from within Windows* (Version 3.0 or later) on an MS-DOS PC.
The DDM-2000 OC-12 Multiplexer uses flash erasable program memory(EPROM) devices that can be upgraded through direct download from an MS-DOS PC. Upgrades are made available through the distribution of floppy diskscompatible with the recommended PCs.
Modem Access 6
The rear access CIT interface (CIT 2) is configured as DTE to allow a permanentmodem connection without requiring a null modem. However, a null modem isrequired when connecting a CIT directly to the rear access DTE interface. CITaccess via a modem connection is identical to local CIT access. Automaticselection (autobaud detection) data rates of 1200, 2400, 4800, 9600, and 19,200baud are provided for both CIT interfaces.
NOTE:The DDM-2000 OC-12 Multiplexer CIT interface supports data rates up to19,200 baud but does not provide flow control. Some terminals and PCswhen set for higher data rates will not work properly at these rates withequipment like the DDM-2000 OC-12 Multiplexer that does not provide flowcontrol. The system may appear to stop working when reports or longprompts are displayed. If this happens, try setting the terminal to a lowerdata rate. The data rate of the DDM-2000 OC-12 Multiplexer isautomatically set to match the data rate of the terminal (autobaud).

The NCR* 3170 computer and the AT&T Safari† computer have abuilt-in modem and meet the modem requirements.
The following stand-alone modems meet the modem requirements and can beused with the DDM-2000 OC-12 system. This is not an exhaustive list ofcompatible modems:
■ Paradyne† 2224-CEO modem (at 1200 and 2400 baud)
■ Paradyne 2224 modem (at 1200 and 2400 baud)
■ Paradyne 4024 modem (at 1200 and 2400 baud)
■ Paradyne 2296 modem (at 4800 and 9600 baud)
■ Hayes ‡ V-series Smartmodems
■ Penril § Alliance V.32 modem.
Remote Access Using the Data CommunicationsChannel (DCC) 6
The DDM-2000 OC-12 system supports CIT remote access from the localterminal to a remote system using the data communications channel (DCC) overOC-N interfaces or the IAO LAN. The DDM-2000 OC-12 system supports oneincoming remote login session and one outgoing login session over the DCC at atime. For example, a local user can gain remote access to a remote DDM-2000 inthe same subnetwork at the same time a remote user at another DDM-2000 in thesubnetwork can gain remote access to the local system. CIT remote login is alsosupported in multi-vendor subnetworks, but only between DDM-2000 Multiplexers(or from FT-2000 to DDM-2000).
Operations Interworking (OI) also allows remote logins between DDM-2000 andthe SLC-2000 Access System and from the FT-2000 OC-48 Lightwave System toother Lucent 2000 Product Family systems in the same subnetwork.

CPro-2000 Graphical User Interface andProvisioning Tool 6
The CPro-2000 Graphical User Interface (GUI) and Provisioning Tool is aMicrosoft* Windows based user interface that can optionally be used with theDDM-2000 OC-12 Multiplexer. The tool simplifies and mechanizes administration,maintenance, and provisioning operations. With the tool a user can:
■ Display and control cross-connections at each NE in a ring and the entirering, including dual ring interworking (DRI) (for example, drop and continuepaths at DRI nodes).
■ Obtain and display graphical images of the ring configuration, equipment,and cross-connections.
■ Perform an analysis of the ring to detect provisioning errors.
■ Retrieve and store data about a selected NE.
■ Backup and restore provisioning information including cross-connections,DS1 port options, DS3 port options, EC-1 port options, and OC-3 lineoptions.
In response to a user, the tool automatically compiles and sends all the necessarycommands to perform a task. If the user is provisioning cross-connections, forexample, the tool automatically prevents provisioning errors by comparing the newprovisioning information with the ring inventory. For more information, see 365-576-130, CPro-2000 User Manual, Release 7.0. See Section 10, "TechnicalSpecifications," for PC requirements to use the tool.
User Panel 6
The user panel for the Group 4 shelf, shown in Figure 6-3, provides system-levelinformation and control functions, while the ACTIVE and FAULT LED on eachfaceplate provide circuit pack level information. These features let manyoperations tasks (for example, fault isolation or circuit pack replacement) to beperformed when a CIT or external test equipment is not available.
The user panel is a factory-installed unit mounted next to the right-hand flange.Additional LEDs and controls are mounted on the SYSCTL faceplate to supportbasic operations, administration, and maintenance functions without a CIT.

User Panel LEDs 6
The user panel LEDs show a composite of all alarms and status conditions in thelocal shelf. The composite is defined as follows:
■ The highest level alarm LED (CR, MJ, PMN, or MN) of all alarms at thelocal shelf is lit. (At most, one alarm LED will be lit at any time.)
■ The ABN LED is lit if an abnormal condition exists on this shelf.
■ The ACO LED is lit if the alarm cutoff function is active on this shelf.
■ Each PWR ON LED is lit if the local shelf is receiving −48 V power from itspower feeders.
■ The NE ACTY LED is lit if any alarm, ABN, or "activity" condition exists onthis shelf.
When this composite information is being displayed on the user panel, the7-segment FE ID is blank.
FE SEL Pushbutton 6
In previous DDM-2000 OC-12 releases the FE SEL pushbutton allowedtechnicians to see far-end DDM-2000 conditions from the local shelf. Starting withOC-12 Release 7.0 and all later OC-12 TARP releases, when the FE SELpushbutton is pushed for the first time, the FE ID display shows "L" and the userpanel LEDs show the conditions of the local shelf only.
Each time the FE SEL pushbutton is pushed again within 15 seconds, the FE IDdisplay will show the local shelf address (with the decimal point), and the userpanel LEDs will again show a composite of the alarm and status condition of thatsame shelf.
ACO/TST Pushbutton 6
The ACO/TST pushbutton tests all the LEDs on the shelf. All LEDs on the shelfwill be lit while the pushbutton is pressed. If the ACO pushbutton is pressed andheld for more than 2 seconds, the three digits of the software release number aredisplayed in the 7-segment FE ID display. If there are any active alarms when theACO pushbutton is pressed, the audible office alarms will be silenced and theACO LED (part of the pushbutton) on the user panel will be lit.

UPD/INIT Pushbutton 6
This pushbutton is used to initialize a controller when it is first installed in a shelf,to update the system's internal equipment inventory when signals or equipmentare removed from the shelf, and when circuit pack options are changed. Thesystem automatically detects new equipment or signals added to the shelf. Inthese cases, it is not necessary to push the UPD/INIT pushbutton.
An optical switch on the BBG8/BBG8B SYSCTL circuit pack latch causes asuspension of controller operations and an “F” to be displayed on the controllerpanel display when the latch is pulled. Closing the latch causes a controller reset.

Equipment Indicators 6
FAULT Indicators 6
Red FAULT indicators are provided on all circuit packs. Retainer cards and theBBF5 JMPR circuit pack do not have LEDs. The circuit pack FAULT indicator is litwhenever a failure has been isolated to that pack.
Common failures (for example, power, synchronization, control, etc.) do not causethe FAULT indicators on all circuit packs affected by the failure to be lit; only theFAULT indicator on the failed pack is lit.
FAULT indicators on high- and low-speed transmission interface and timing circuitpacks are flashed when a failure of the incoming signal is detected (for example,LOS, LOF, LOP, or crossing of the signal fail or signal degrade threshold).
The FAULT LED on the BBG9 OHCTL blinks when a failure of the DCC from a far-end shelf is detected.
ACTIVE Indicators 6
A green ACTIVE indicator is provided on each 1x1, 0x1, and 1+1 protected circuitpack. It indicates which circuit packs, "service" and/or "protection," are active(carrying service) at any given time.
Although there is no ACTIVE LED on each low-speed circuit pack to indicate it iscarrying service, the status of the circuit packs can normally be determinedwithout the CIT. If a service DS1 circuit pack FAULT LED is lit and the DS1protection circuit pack FAULT LED is not lit, then the protection circuit pack iscarrying service and the failed circuit pack can be removed. The exception to thisrule is if a manual protection switch has been executed. In this case, the ABN LEDon the user panel will be lit and the user will have to use a CIT to check the statusof the system.

The DDM-2000 OC-12 Multiplexer provides relay contacts for wiring to the officeaudible and visual alarms. Contacts are provided for each alarm condition: CR(critical), MJ (major), and MN (minor).
The MJ and CR contact closures are designed to allow these office alarms to beORed together and reported as an office MJ alarm.
The CR alarms are fail-safed against power failures. They are activated even if theshelf loses both power feeders.
The audible office alarms for a given site are silenced through activation of theACO function. Visual alarms are not extinguished by the ACO function.
An alarm hold-off delay is provided, to prevent transient failures from causingunnecessary maintenance activity. The office alarms will not be activated unless acondition of greater duration than the alarm hold-off delay occurs. When a failureclears, an alarm clear delay prevents premature clearing of the alarm.
As with the user panel indicators, when multiple alarms are active, the highestlevel office alarm (audible and visual) is activated. When the highest level alarmclears, the office alarm "bumps down" to the next highest level active alarm.
If the ACO function has been activated to silence all active audible alarms, thenwhen a "bump down" occurs the audible alarms remain silent. (That is, the lowerlevel visual alarm is activated, but the corresponding audible alarm is not re-activated.) If another alarm occurs while the ACO is active, the highest levelaudible alarm is activated even if the new alarm is a lower level condition. (Forexample, if a MJ and MN alarm were active and silenced via the ACO and anotherMN alarm occurred, the MJ audible alarm would sound.)
See Section 8, "Administration and Provisioning," for more information.

TL1/X.25 Interface 6
The DDM-2000 OC-12 Multiplexer supports a TL1/X.25 interface via a rearaccess, synchronous, EIA-232-D port capable of speeds of 1200, 2400, 4800,9600, and 19,200 baud to control and report alarm and status conditions and PMdata to an alarm surveillance OS such as Bellcore's NMA. This TL1/X.25 interfaceprovides detailed information such as identifying specific circuit packs andfacilities.
The TL1 maintenance messages of the DDM-2000 OC-12 Multiplexer are basedon Bellcore's TR-NWT-000833, Issue 3, Rev. 1, Issue 4, Supplement 1, and Issue5, Rev. 1. The TL1 provisioning messages of the DDM-2000 OC-3 Multiplexer arebased on Bellcore's TR-NWT-000199, Issue 2, and TA-NWT-000199, Issue 6,Supplement 1.
The DDM-2000 serves as the TL1/X.25 GNE for DDM-2000 TL1-RNEs.DDM-2000 can now serve as the TL1/X.25 GNE for FT-2000 TL1-RNEs (as analternative to FT-2000’s existing capability to serve as the TL1/X.25 GNE forDDM-2000 TL1-RNEs). ITM SNC (see following paragraph) or other vendor NEs,such as Tellabs TITAN, may also be the TL1/X.25 GNE for DDM-2000 TL1-RNEs.The reverse is not necessarily supported; the DDM-2000 can not serve as a TL1/X.25 GNE for Tellabs TITAN R5.0.
The GNE serves as a single interface to the OS for the Lucent NEs in the sameLucent 2000 Product subnetwork, using X.25 interfaces. The GNE receivesoperations information from all the Lucent NEs through the DCC and reports thisinformation, as well as its own information, to the OS. The operations informationis in the form of TL1 messages. Through the GNE, the OS can send TL1commands to any Lucent NE in the subnetwork.
The OS can use more than one NE as a GNE to provide redundancy and/or todistribute TL1 message volume across multiple X.25 links. For example, two NEscould each be connected via their TL1/X.25 interface to the same type of OS withone GNE serving as a backup for the other.
Autonomous and command/response messages are also supported. Section 10,"Technical Specifications," provides detailed specifications for the X.25 interface.Detailed information about engineering a subnetwork with multiple DDM-2000GNEs and the input and output parameters for TL1 messages is provided in 824-102-151, DDM-2000 Multiplexers Operations Systems Engineering Guide.

ITM SNC 6
ITM SNC is an element management system that supports SONET NEs such asthe Lucent Technologies’ DDM-2000, FT-2000, SLC®-2000, and the Fujitsu®
Lightwave Multiplexer (FLM). ITM SNC provides fault, provisioning, configuration,and security management functions via a Graphical User Interface (GUI). Throughthese functions, ITM SNC is able to support communication multiplexing orconcentration, to provide network security, and to record all database changes.ITM SNC also provides a cut-through capability, allowing the ITM SNC user toaccess an NE through its native command set.
ITM SNC operates as an enhanced graphical tool and as a general configurationmanagement aid. It provides NE, port, cross-connection, and path provisioning,as well as flow-through from provisioning operations systems (OSs) to NEs. ITMSNC also provides fault management through subnetwork alarm and event pre-processing prior to sending fault information to a network surveillance systemsuch as the Network Monitoring and Analysis-Facility (NMA-F).
IAO LAN Interface 6
DDM-2000 OC-3 R13.0 and OC-12 R7.0 support an IntrAOffice LAN (IAO LAN)interface for operations data communications. The IAO LAN is necessary tosupport the following ITM SNC R5.0 features:
■ ITM SNC as the TL1-GNE for DDM-2000
■ ITM SNC software download to DDM-2000.*
Because the IAO LAN is effectively an extension of the SONET DCC, the IAOLAN may also be used to join multiple, otherwise separate subnetworks. All NE-to-NE OI features that are supported by DDM-2000 OC-3 R13.0 and OC-12 R7.0over the DCC are also supported over the IAO LAN.
The IAO LAN interface is a software-only enhancement to DDM-2000 OC-3 R13.0and OC-12 R7.0. The current DDM-2000 overhead controller (OHCTL) circuitpacks already support the IAO LAN interface (via an RJ45 connector).DDM-2000’s IAO LAN interface is compatible with 10BaseT Ethernet hubsoperating at 10 Mb/s over 4-wire twisted pair cables (per Bellcore GR-253, ANSI/IEEE 802.2 [ISO 8802-2] and ANSI/IEEE 802.3 [ISO 8802-3]).
See also 824-102-144, Lucent Technologies 2000 Product Family Multi-VendorOperations Interworking Guide.
* This feature will be useful when upgrading from DDM-2000 OC-3 R13.0 and OC-12 R7.0 tosubsequent releases.

Compatibility 7
The BBG8/BBG8B SYSCTL, BBF2B TGS, BBF4 TG3, 21D/21D-U OLIU, and21G/21G-U/21G2-U OLIU circuit packs are common to both the DDM-2000 OC-3and OC-12 Multiplexers.
Universal Optical Connector 7
Circuit packs having a "-U" after their designation indicate that these circuit packshave a universal optical connector.
The following circuit packs are available with the connector:
■ 21D-U OLIU
■ 21G-U/21G2-U OLIU
■ 23G-U OLIU
■ 23H-U OLIU.
This connector (Figure 7-1) is a two-part connector consisting of a faceplate-mounted block and an optical buildout. The faceplate block optionally supports anST®, SC, or FC-type optical buildout.
A 0 dB ST-type connector is shipped as standard. Optional SC, or FC 0 dB, orattenuated buildouts can be ordered separately. See Section 10, "TechnicalSpecifications," for a list of universal buildout attenuators.

Control 7
The control system controls and reports the status of the transmission signalthrough the DDM-2000 OC-12 Multiplexer. All system features are implemented orsupported through the control system. However, transmission is unaffected bycontrol system failure. If a controller does fail, protection switches are not done.Therefore, if there is another circuit pack failure requiring a protection switch alongwith the controller failure, service may be affected depending on the function ofthe failed pack. The control system continuously monitors the equipment todetermine if a protection switch is necessary and to provide equipmentperformance information.
The control system in each shelf in a subnetwork can communicate with thecontrol system of other shelves in that subnetwork via the synchronous opticalnetwork (SONET) section data communications channel (DCC). This allows auser at one point in the subnetwork to control the shelves throughout the network.All system features are implemented or supported through the control system.
Control Circuit Packs 7
There are two control circuit packs, the BBG8/BBG8B SYSCTL and the BCP4OHCTL. Both the SYSCTL and OHCTL are required for all applications.

BBG8/BBG8B SYSCTL Circuit Pack Description 7
Purpose of Circuit 7
The BBG8/BBG8B SYSCTL circuit pack is the main system controller in thesystem. Together with its companion OHCTL, it has control over all shelf functionsand provides all user interfaces into the system. The BBG8/BBG8B SYSCTL mustbe used with the BCP4 OHCTL.
BBG8/BBG8B SYSCTL Faceplate Controls andIndicators 7
The BBG8/BBG8B SYSCTL circuit pack faceplate controls and indicators areshown in Figure 7-2. The SYSCTL has a red FAULT LED and a 7-segmentnumeric LED display, as well as the FE SEL and UPD/INIT pushbuttons on itsfaceplate. The red FAULT LED lights on detection of a circuit pack failure.

An optical switch on the BBG8/BBG8B SYSCTL circuit pack latch causes asuspension of controller operations and an "F" to be displayed on the controllerpanel display when the latch is pulled. Closing the latch causes a controller reset.These controls and indicators are discussed in more detail under "User Panel" inSection 6, "Operations Interfaces."
General Description of Operation 7
The SYSCTL circuit pack provides the majority of the control functions on theshelf. These include circuit pack monitoring, performance monitoring (PM),protection switching, and user interfaces.
The SYSCTL, which contains a microprocessor, controls links to all other circuitpacks in the system and links to user interfaces. The processor also provides linkaccess procedure (LAPD) and LAPD packet data processing to support SONETsection DCC.

Control Circuitry 7
Processor . 7Figure 7-3 provides an overall block diagram of the SYSCTL circuitpack. This processor is the highest level processor in the system.
Memory 7
Program Flash-EPROM . 7The main program is stored in the flash-EPROM, whichcombines the nonvolatility of EPROM with the in-circuit reprogramming ability ofelectrically erasable programmable read-only memory (EEPROM). ElectricallyErasable Programmable Read-Only Memory FEPROM allows in-service softwareupgrades to be performed locally or remotely without replacing the SYSCTLcircuit pack. Program upgrades of remote DDM-2000 OC-12 shelves can also bedone via the overhead channel from the central office (CO). Of course, softwareupgrades may also be accomplished by replacing circuit packs with packs thathave already had software upgrades.
RAM . 7The main processor's random access memory (RAM) is used to store allvolatile information, such as system alarms, PM information, and parameters forthe main processor's operating system.
EEPROM . 7All nonvolatile parameters, such as provisioning, are stored in theEEPROM, which maintains its data indefinitely during a power loss.

Transmission/Timing Circuit Pack Interfaces 7
The main processor can read and write parameters on the transmission circuitpacks through a custom serial interface called the intra-shelf control bus. Thesecircuit packs have a built-in serial link receiver which provides an address mapinto the device. Through this interface, the processor accesses the customdevices and circuit pack parameters, as well as a small EEPROM which storeseach circuit pack's inventory information (Common Language CLEI* code, date ofmanufacture, etc.). Through this link, the main processor can also light thefaceplate LEDs on the circuit packs.
Redundancy has been built into this bus to allow a pack to be switched out ofservice in the event of a failure within a circuit pack.
Operation Interfaces 7
The SYSCTL supports all of the operations interfaces described in Section 6,"Operations Interfaces."
OC-12 Transport Overhead Channel 7
The OHCTL terminates an overhead channel from each main and function unitslot in the shelf, passing information to the SYSCTL over the intra-shelf processorbus.

Power Monitoring and Fan Control 7
The SYSCTL monitors the two −48 volt feeders and generates an alarm if onefails. It also monitors AC power in a remote terminal application via a power minoralarm input closure and can control the external fan, based on an on-boardtemperature sensor. The system also monitors the fan control relay for contactfailure.
If the voltage to the shelf drops below the safe operating voltage, the system willsuspend normal operations and wait for safe operating voltage to return. This isreferred to as "brownout protection." Assuming a sufficient voltage level, an "L" willbe displayed on the SYSCTL. The BBG8 operates in integrated grounding(-48VRTN connected to frame ground) architecture systems. The BBG8Boperates in either integrated or isolated grounding (-48VRTN not connected toframe ground) architecture systems.
Interface to Other DDM-2000 OC-12 Shelves 7
The SYSCTL interfaces with SYSCTLs of other DDM-2000 OC-12 shelvesthrough intershelf cabling. This interface allows the user to access eachDDM-2000 OC-12 shelf in a bay via a modem or craft interface terminal (CIT)connected to any shelf in that bay.
Power Circuitry 7
The SYSCTL receives two sources of −48 volts which are diode ORed, fused, andfiltered prior to conversion to a +5 volt source to power the rest of the circuit pack.

Synchronization Functions 7
The DDM-2000 OC-12 Multiplexer supports three synchronization modes:
1. DS1 timing input from stratum 3 or better office clock for CO applications
2. Free-running in CO applications when external timing inputs are notavailable
3. Line (formerly loop) timing for remote timing functions.
In addition, the BBF2B/BBF4 TGS/TG3 circuit pack provides a DS1 timing outputthat is used for network synchronization and allows line (formerly loop) timing andDS1 Output timing to be derived from the main OLIUs.
The timing circuit packs distribute clock and frame signals, derived from theselected reference source, to the transmission circuit packs.

General Description of Operation 7
The TG circuit pack provides timing signals to the DDM-2000 OC-12 circuit packs.The TG circuit pack is microprocessor controlled and has the capability tosynchronize to external DS1 references or to loop references from an incomingoptical signal. The on-board oscillator has sufficient accuracy to provide timingsignals without synchronization references for point-to-point systems (free-running) and a DS1 timing output for network timing distribution.
The TG circuit pack supports three timing modes to serve a wide range ofDDM-2000 OC-12 synchronization needs: external timing, line (formerly loop)timing, and free-running. In addition, external timing or line (formerly loop) timingwith DS1 output provisioned for network synchronization is provided.
In external timing mode, each TG circuit pack accepts one DS1 reference from anexternal stratum 3 or better clock and one cross-coupled from its companion TGcircuit pack. A high-stability digital phase-locked loop (DPLL) removes anytransient impairments on the DS1 reference for improved jitter performance.
In line (formerly loop) timing mode, the TG circuit pack derives local shelf timingfrom the received OC-N signal.
In free-running mode, the TG circuit pack derives timing from a high stabilitytemperature-compensated, voltage-controlled crystal oscillator.
In case of unprotected synchronization reference failure, the TG circuit pack willswitch to "holdover mode" and continue to provide system timing, using theinternal oscillator to maintain the last known good reference frequency.
DS1 Timing Output 7
The DS1 Output provided by the TG circuit pack can be provisioned to one of twomodes of operation:
■ MULT
— This mode is normally used to distribute a DS1 timing reference toother shelves in the bay. In this mode, the distributed DS1 Output isbuffered from the external DS1 reference that is input to the shelf.
■ SYNC OUT
— This mode is used to distribute a derived DS1 timing reference to aBITS. In this mode, the distributed DS1 Output is based on thetiming signal the TG circuit pack has derived from the receivedOC-12 signal from the main OLIUs.
— If the DS1 output is provisioned for SYNC OUT mode, DS1 AIS willbe inserted on detection of unprotected OC-N line failure.

Timing Circuitry 7
DS1 External Timing. 7Each TG circuit pack receives one DS1 reference signalwhich it monitors and from which it recovers a clock signal. The recovered clock iscross-fed to its companion TG circuit pack in the same shelf. If the microprocessoron one TG circuit pack detects an incoming DS1 reference failure, it will signal themicroprocessor on the companion TG circuit pack. Thus, each TG circuit pack hastwo DS1 references to choose from, one which is input directly and the othercross-fed. Both TG circuit packs will normally select the same DS1 input. A loss ofboth DS1 references will result in the TG circuit pack entering holdover mode.
Line Timing. 7The reference signal feeding the phase-locked loop is selectedfrom the internal oscillator or a loop-timing clock derived from the incoming opticalline. In line (formerly loop)-timing mode, the OC-N line being selected fortransmission is also selected as the timing reference. Loss of both line timingreferences will cause the TG circuit pack to go into holdover mode to maintainsystem timing.
Free-Running. 7For free-running operation, the TG derives timing from atemperature-compensated, voltage-controlled crystal oscillator (TCVCXO) and adigital phase-locked loop (DPLL) with a full temperature range end-of-lifeaccuracy of ±15 parts-per-million (ppm) for the BBF2B TGS, and ±4.6 ppm for theBBF4 TG3.
DS1 Output. 7The DS1 output port of the TG circuit pack can be provisioned foreither MULT or SYNC OUT mode via a hardware switch. In the SYNC OUT mode,the derived DS1 output signal is generated from the incoming OC-N lines throughtiming synchronization signals from the DDM-2000 OC-12 main OLIUs (main-b-1or main-b-2), which is the default. In the MULT mode, the DS1 output signal isbuffered from an external DS1 input reference. This external reference is typicallya DS1 from a building integrated timing supply (BITS).
Selection of these timing synchronization signals for the DS1 output in SYNCmode is controlled by the SYSCTL circuit pack. This selection can be provisionedvia software command to "track" the active received side of the OC-N line used fortransmission, to always select its timing from the specified OC-12 line (main-b-1or main-b-2) regardless of its maintenance condition. Loss of timing reference forthe DS1 output will result in the insertion of DS1 AIS on this output port.
Holdover. 7The TG circuit pack has an internal TCVCXO that will maintain shelftiming in the event of an unprotected timing DS1 reference failure (that is, holdovermode). The TGS (BBF2B) will maintain frequency stability to better than a SONETminimum clock (SMC) accuracy. The TG3 (BBF4) will maintain frequency stabilityto better than a stratum 3 accuracy. Beyond this 24 hour period holdover willgradually return to a free-run accuracy.

Clock Output Functions 7
Intra-shelf Timing Distribution. 7The generated timing signals are distributedthrough output drivers to the main and function unit slots. The TG circuit packprovides eight differential 51.84-MHz master clock signals and eight differential8-kHz composite STS-1 frame sync signals. In the 8-kHz sync signal, every fourthpulse is stretched to double width, providing an embedded 2-kHz reference for thevirtual tributary (VT) superframe synchronization.
DS1 Outputs . 7The DS1 output port can be provisioned by hardware switches forMULT mode or DS1 timing synchronization (SYNC OUT) mode.
■ SYNC OUT Mode
— The DS1 output port of the BBF2B TGS circuit pack can beprovisioned to be a derived DS1 signal traceable to a receivedoptical line used for network timing distribution. The SYNC OUTcapability is available for a DDM-2000 set for external-timing or line-timing.
■ MULT Mode
— The DS1 output port of the TGS circuit pack can be provisioned tooutput a buffered copy (at a DSX level) of the DS1 signal at the inputport. A DS1 traceable source is applied to the first DDM-2000 shelf.The output of the first shelf is then cabled to the second shelf, andall subsequent shelves fed from the previous ones. In this way, aMULT chain is formed from a single DS1 reference. The MULTcapability is only available for a DDM-2000 provisioned for external-timing.
Protection Circuitry 7
In both external and line (formerly loop)-timing modes, the synchronizationreferences are continuously monitored for error-free operation. If the activereference becomes corrupted, the TG circuit pack will select the standbyreference without causing service degradations (that is, hitless referenceswitching). If both reference inputs are corrupted, the TG circuit pack entersholdover mode where the DPLL holds the on-board oscillator frequency at the lastgood reference sample while the references are repaired.
In addition, optional 1x1 nonrevertive TG circuit pack protection is provided. Whenthe active TG circuit pack microcontroller determines that its clock output is out oftolerance, it suppresses its timing outputs and signals its TG circuit packcompanion unit of its failed condition. The suppressed timing outputs cause atiming hardware switch to the standby TG circuit pack by the transmission circuitpacks.

7-22 Issue 1 December 1997
Fault Detection Circuitry 7
The TG circuit pack has in-service and out-of-service built-in test capability. In-service testing is continuous and errors are reported when they occur to theSYSCTL via the intra-shelf control bus. An out-of-service test is performedwhenever the TG circuit pack is inserted or recovers from a transient failure.
The incoming DS1 references are monitored for:
■ LOS (128 consecutive zeros)
■ DS1 AIS
■ LOF
■ Excessive out-of-frame count
■ Greater than 10-3 bit error ratio (BER).
Power Circuitry 7
The TG circuit pack receives two sources of −48 volts which are diode ORed,fused, and filtered prior to conversion to a +5 volt source to power the rest of thecircuit pack. A failure of the fuse or converter causes the red FAULT LED to light.
TG Hardware Settings 7
The TG circuit pack option switches provide the following functions:
■ DS1 Reference Line Coding — Selects either alternate mark inversion(AMI) or AMI with bipolar 8-zero substitution (B8ZS) line coding for bothDS1 input and DS1 output.
■ DS1 Reference Format — Selects either super frame (SF) or extendedsuper frame (ESF) for both DS1 input and DS1 output.
■ Timing Mode — Sets timing mode to free run, external DS1, or line(formerly loop) timed.
■ DS1 output mode — Sets DS1 output (SF or ESF "all ones" signal) forintra-shelf timing derived either from DS1 external input or from networktiming distribution derived from received line. Reference for DS1 timingoutput is taken from the main OLIUs.
■ Sets equalizer switch for proper cable length when provisioned for SYNCOUT mode. Equalizer settings will be automatically set to shortest cablelength when the DS1 output is provisioned for MULT mode.

General Description of Operation 7
The BBG11 3DS3 circuit pack provides bidirectional transport of three DS3signals through the DDM-2000 OC-12 Multiplexer in either clear channel (CC)mode, violation monitor and removal (VMR) mode, or violation monitor (VM) modeby mapping the DS3 into an STS-1 signal. The 3DS3 circuit pack performsmaintenance and provisioning functions associated with the STS-1 and DS3signals and provides access to the STS-1 path overhead. The 3DS3 circuit packinterfaces to the TSI circuit pack at the STS-1 rate, to the DSX-3, and to theSYSCTL, and it receives timing signals from the TSI circuit pack. Whenprovisioned for the clear channel (CC) mode, the 3DS3 can transport any DS3rate signal that meets specified electrical interface requirements. Whenprovisioned for the VMR or VM mode, the DS3 signal must meet both electricaland DS3 frame format requirements.
Detailed Description of Operation 7
Transmission Circuitry 7
Transmit Direction. 7Figure 7-11 provides an overall block diagram of the BBG113DS3 circuit pack. The transmit direction is the direction towards the STS-1signal, and the receive direction refers to the direction towards the DSX-3. In thetransmit direction, the BBG11 3DS3 receives three incoming bipolar 3-zerosubstitution (B3ZS) encoded DS3 signals from the DSX-3. A closed protectionrelay contact routes the DS3 signal to a circuit that splits the signal and sends oneoutput to the companion (standby) circuit pack and the other to its own receiver.The BBG11 3DS3 receiver performs equalization and clock recovery, performsB3ZS decoding and optional automatic AIS insertion which it synchronizes to theSTS-1 rate; inserts STS-1 path overhead; and transmits the STS-1 rate signal tothe TSI circuit packs.
Receive Direction. 7The BBG11 3DS3 receives STS-1 data from both the activeand standby TSI circuit packs, selects one set of STS-1s, performs pointerinterpretation, processes and removes the path overhead, desynchronizes theembedded DS3, provides a provisionable VMR function, and then B3ZS-encodesthe signal for transmission to the DSX-3. A jumper allows the user to insert orremove a line build-out (LBO) network (225 ft. of 734A type cable equivalent) toprovide the required signal level and shape at the DSX-3.
Before the DS3 signal is B3ZS-encoded, a VMR function can be provisioned viathe control circuitry for one of three possible modes:
■ VMR with DS3 AIS insertion (default)
■ VM and AIS insertion without removal of violations
■ CC
— With DS3 AIS insertion
— Without DS3 AIS insertion.

Control Circuitry 7
The BBG11 3DS3 circuit pack interfaces with the SYSCTL via the intra-shelfcontrol bus. Redundancy in the intra-shelf control bus assures the level of controlrequired to perform protection switching and alarming of a faulty circuit pack. TheBBG11 3DS3 provides maintenance elements for reporting the status of thecircuit pack, status of the incoming STS-1 and DS3 signals, as well as the circuitpack inventory information (CLEI code, date of manufacture, etc.). Thesemaintenance elements are used by the SYSCTL for fault detection and isolation.Conversely, the BBG11 3DS3 responds to control signals from the SYSCTL (suchas active and fault LED controls).
Timing Circuitry 7
The BBG11 3DS3 circuit pack derives its timing information from the recoveredDS3 clock of the DSX-3 incoming signal. In the transmit direction, a 44.736 MHzclock is recovered from the incoming DS3 signal and is used to recover DS3 data.In the receive direction, a smoothed 44.736 MHz clock is generated by a phase-locked loop to accompany the DS3 signal extracted from the STS-1 payload.
In addition to the recovered DS3 clock, the BBG11 3DS3 circuit pack requiresSTS-1 timing supplied by the TSI circuit pack, via the circuit pack edge connector,from the backplane.
Protection Circuitry 7
Optional 1x1 nonrevertive BBG11 3DS3 circuit pack protection is provided. Switchpoints for the STS-1 side of the BBG11 3DS3 are located on the TSI circuit packs.Switch points for the DS3 side are implemented with relays on the 3DS3 circuitpack. To ensure that the relays can be operated when the circuit pack fails, therelay is controlled by the SYSCTL via the control interfaces. Also, if power to theboard is lost, the relay switches autonomously to the standby state. When a newboard is inserted, it defaults to the standby state until provisioned active by theSYSCTL.
363-206-295Circuit Pack Descriptions
Issue 1 December 1997 7-29
On the BBG11 3DS3 side, the DS3 inputs from a DSX-3 are sent to both theactive and standby BBG11 3DS3 circuit packs. Only the active unit selects theDS3 input. The SYSCTL circuit pack supervises the state of the active andstandby units so that the relay state of each is always the inverse of the other. Thehybrid on the active unit splits the DS3 input signals and sends them to thestandby unit and to its own receiver. To implement a protection switch on the DS3side, the SYSCTL switches the relays on each unit to their opposite state.
When a BBG11 3DS3 is removed, shorting contacts on the backplane connectoroperate so that the DS3 input signal from its companion unit is returned for propertermination.
Fault Detection Circuitry 7
Monitoring and Testing. 7The BBG11 3DS3 circuit pack has in-service andout-of-service built-in test capability. In-service testing is continuous and errorsare reported when they occur to the SYSCTL via the intra-shelf control bus. Anout-of-service test is performed whenever the BBG11 3DS3 circuit pack isinserted or recovers from a transient failure.
Loopbacks. 7Two loopbacks are provided for each DS3 interface on the BBG113DS3 circuit pack. The terminal loopback bridges the DS3 desynchronizer outputsignal (transmitted towards the DSX-3) back into the DS3 synchronizer input.Operation of this loopback does not affect the signal transmitted to the DSX-3.The facility loopback bridges the STS-1 output signal to the TSI back towards theDSX-3. Operation of this loopback does not affect the signal transmitted to thefiber. Both loopbacks are controlled by the SYSCTL through the intra-shelf controlbus.
Power Circuitry 7
The BBG11 3DS3 circuit pack receives two sources of −48 volts that are in turndiode ORed, fused, and filtered before conversion to +5 volts to power the rest ofthe circuit pack. A failure of the fuse or converter causes the red FAULT LED tolight.

The transmit direction is the direction towards theSTS-1 signal, and the receive direction refers to the direction towards the DSX-3.In the transmit direction, the BBG11B 3DS3 receives three incoming B3ZSencoded DS3 signals from the DSX-3. A closed protection relay contact routes theDS3 signal to a circuit that splits the signal and sends one output to thecompanion (standby) circuit pack and the other to its own receiver. The BBG11B3DS3 receiver performs equalization and clock recovery, B3ZS decoding, optionalautomatic DS3 AIS insertion, and a provisionable VMR function. The BBG11BDS3 then synchronizes and maps the DS3 to the STS-1 rate, inserts STS-1 pathoverhead and transmits the STS-1 rate signal to the TSI circuit packs.
Receive Direction. 7The BBG11B 3DS3 receives STS-1 data from both the activeand standby TSI circuit packs, selects one set of STS-1s, performs pointerinterpretation, processes and removes the path overhead, desynchronizes theembedded DS3, provides a provisionable VMR function, and then B3ZS-encodesthe signal for transmission to the DSX-3. A jumper allows the user to insert orremove a line LBO network (225 ft. of 734A-type cable equivalent) to provide therequired signal level and shape at the DSX-3.
Before the DS3 signal is B3ZS-encoded (receive direction) or decoded (transmitdirection), a VMR function can be provisioned via the control circuitry for one ofthree possible modes:
■ VMR with DS3 AIS insertion (default)
■ VM and AIS insertion without removal of violations
■ CC
— With DS3 AIS insertion
— Without DS3 AIS insertion.

Control Circuitry 7
The BBG11B 3DS3 circuit pack interfaces with the SYSCTL via the intra-shelfcontrol bus. Redundancy in the intra-shelf control bus assures the level of controlrequired to perform protection switching and alarming of a faulty circuit pack. TheBBG11B 3DS3 provides maintenance elements for reporting the status of thecircuit pack, status of the incoming STS-1 and DS3 signals, as well as the circuitpack inventory information (CLEI code, date of manufacture, etc.). Thesemaintenance elements are used by the SYSCTL for fault detection and isolation.Conversely, the BBG11B 3DS3 responds to control signals from the SYSCTL(such as active and fault LED controls).
Timing Circuitry 7
The BBG11B 3DS3 circuit pack derives its timing information from the recoveredDS3 clock of the DSX-3 incoming signal. In the transmit direction, a 44.736 MHzclock is recovered from the incoming DS3 signal and is used to recover DS3 data.In the receive direction, a smoothed 44.736 MHz clock is generated by a phase-locked loop to accompany the DS3 signal extracted from the STS-1 payload.
In addition to the recovered DS3 clock, the BBG11B 3DS3 circuit pack requiresSTS-1 timing supplied by the TSI circuit pack, via the circuit pack edge connector,from the backplane.
Protection Circuitry 7
Optional 1x1 nonrevertive BBG11B 3DS3 circuit pack protection is provided.Switch points for the STS-1 side of the BBG11B 3DS3 are located on the TSIcircuit packs. Switch points for the DS3 side are implemented with relays on the3DS3 circuit pack. To ensure that the relays can be operated when the circuit packfails, the relay is controlled by the SYSCTL via the control interfaces. Also, ifpower to the board is lost, the relay switches autonomously to the standby state.When a new board is inserted, it defaults to the standby state until provisionedactive by the SYSCTL.

On the BBG11B 3DS3 side, the DS3 inputs from a DSX-3 are sent to both theactive and standby BBG11B 3DS3 circuit packs. Only the active unit selects theDS3 input. The SYSCTL circuit pack supervises the state of the active andstandby units so that the relay state of each is always the inverse of the other. Thehybrid on the active unit splits the DS3 input signals and sends them to thestandby unit and to its own receiver. To implement a protection switch on the DS3side, the SYSCTL switches the relays on each unit to their opposite state.
When a BBG11B 3DS3 is removed, shorting contacts on the backplane connectoroperate so that the DS3 input signal from its companion unit is returned for propertermination.
Fault Detection Circuitry 7
Monitoring and Testing. 7The BBG11B 3DS3 circuit pack has in-service andout-of-service built-in test capability. In-service testing is continuous and errorsare reported when they occur to the SYSCTL via the intra-shelf control bus. Anout-of-service test is performed whenever the BBG11B 3DS3 circuit pack isinserted or recovers from a transient failure.
Loopbacks 7
Two loopbacks are provided for each DS3 interface on the BBG11B 3DS3 circuitpack. The terminal loopback routes the DS3 desynchronizer output signal(transmitted towards the DSX-3) back into the DS3 synchronizer input. Operationof this loopback does not affect the signal transmitted to the DSX-3. The facilityloopback routes the STS-1 output signal to the TSI back towards the DSX-3.Operation of this loopback does not affect the signal transmitted to the fiber. Bothloopbacks are controlled by the SYSCTL through the intra-shelf control bus.
Performance Monitoring 7
The BBG11B DS3 circuit pack provides PM circuitry for the following performanceparameters:
■ STS path parameters derived from B3 coding violations
■ DS3 path parameters derived from P-bit coding violations
■ DS3 path parameters derived from frame and multiframe (F&M) bit errors
■ DS3 line errors based on B3ZS violations
■ DS3 P-bit and F&M bit performance monitoring for both directions oftransmission
■ C-bit parity and Far End Block Errors (FEBE) option performancemonitoring for both directions of transmission.

General Description of Operation 7
The BBG12 3STS1E circuit pack provides bidirectional transport of three EC-1signals through the DDM-2000 OC-12 Multiplexer. The 3STS1E circuit packperforms maintenance and provisioning functions associated with the STS-1 andEC-1 signals. The 3STS1E circuit pack interfaces to the TSI circuit pack at theSTS-1 rate, to the STSX-1, and to the SYSCTL, and it receives timing signalsfrom the TSI circuit pack.
Detailed Description of Operation 7
Transmission Circuitry 7
Transmit Direction. 7Figure 7-17 provides an overall block diagram of the BBG123STS1E circuit pack. The transmit direction is the direction towards the fiber andthe receive direction refers to the direction towards the STSX-1. In the transmitdirection, the BBG12 3STS1E receives up to three incoming B3ZS encoded EC-1signals from the STSX-1 cross-connection panel. A closed protection relaycontact routes each EC-1 signal to a circuit that splits the signal and sends oneoutput to the companion (standby) circuit pack and the other to its own receiver.The BBG12 3STS1E receiver performs equalization and clock recovery, B3ZSdecoding, and optional automatic AIS insertion. It performs pointer processing onthe input data stream and outputs three corresponding data streams, time-alignedwith a single frame signal, to the TSI circuit packs.
Receive Direction. 7The BBG12 3STS1E receives two STS-1 data signal inputsfor each of the three EC-1 channels: one from the working TSI circuit pack andone from the standby TSI circuit pack. A jumper allows the user to insert orremove a LBO network (225 ft. of 734A-type cable equivalent) to provide therequired signal level and shape at the STSX-1 cross-connection panel.
Control Circuitry 7
The BBG12 3STS1E circuit pack interfaces with the SYSCTL circuit pack via theintra-shelf control bus. The BBG12 3STS1E circuit pack provides maintenanceelements for reporting the status of the circuit pack, status of the incoming STS-1and EC-1 signals, as well as the circuit pack inventory information (CLEI code,date of manufacture, etc.). These maintenance elements are used by theSYSCTL for fault detection and isolation. Conversely, the BBG12 3STS1Eresponds to control signals from the SYSCTL (such as active and fault LEDcontrols).

General Description of Operation 7
The 21D/21D-U OLIU circuit pack multiplexes three STS-1 signals to an STS-3, insertsthe SONET transport overhead bytes (line and section), and scrambles the resultingsignal. This STS-3 signal drives an LED transmitter to create the IS-3 output.
The received IS-3 signal is converted back to an electrical STS-3. This STS-3 isdescrambled and demultiplexed to three STS-1 signals, and transport overhead isaccessed. Some of the overhead (for example, section datacom channel) is passed viaserial data links to the control packs, while other bytes (for example framing, paritycheck) are processed on-board. Finally, the STS-1 signals run through a pointer-processing step (interpretation and regeneration) to guarantee frame alignment to thelocal system clock before they are sent to the TSI slots. Fiber access is via a pair of ST(21D) or universal (21D-U) lightguide cable connectors from the 21D/21D-U OLIUfaceplate. The 21D/21D-U OLIU operates only on multimode cable.

Transmission Circuitry 7
Transmit Direction. 7The 21D/21D-U OLIU circuitry selects the three STS-1signals from the TSI, adds SONET transport overhead, then byte-interleaves andscrambles the signal in a frame synchronous scrambler. The output from themultiplexer is an STS-3 signal that is used to amplitude modulate the LEDtransmitter, converting the electrical signal to an NRZ-encoded IS-3 optical signal.
Receive Direction. 7In the receive direction, the optical receiver converts the lightpulses from an IS-3 optical signal to equivalent electrical pulses. The receivedsignal may be either NRZ- or RZ-encoded. The output from the optical receivergoes into a timing recovery device. The device recovers received clock (155.520MHz) and uses it to retime the received data, providing a retimed STS-3 signal.The demultiplexer circuit accepts the STS-3 bit stream, frames on the incomingsignal, descrambles it, demultiplexes it into three STS-1 signals, and processesIS-3 transport overhead. The overhead information is sent to the OHCTL circuitpack via the intra-shelf control bus and the transport overhead channel interface.
The STS-1 outputs from the demultiplexer are sent to the pointer processor thatperforms pointer interpretation and generation on each received STS-1, using thelocal timing signals. The output of the pointer processor is three STS-1 signals,frame synchronous to each other.
Control Circuitry 7
The 21D/21D-U OLIU circuit pack interfaces with the SYSCTL and OHCTL circuitpacks.
The 21D/21D-U OLIU provides maintenance elements for reporting the status ofthe circuit pack, status of the incoming STS-1 and IS-3 signals, as well asinventory information (CLEI code, date of manufacture, etc.). These maintenanceelements are used by the SYSCTL for fault detection and isolation. Conversely,the 21D/21D-U OLIU responds to control signals from the SYSCTL, such as LEDoperation and protection switching.
The 21D/21D-U OLIU accesses the IS-3 transport overhead and routes it via thetransport overhead channel interface to the OHCTL.
Timing Circuitry 7
Each TSI circuit pack sends timing signals to each 21D/21D-U OLIU circuit pack.The 21D/21D-U OLIU monitors activity on both timing inputs. It normally selectsthe signals from the active TSI as requested by the SYSCTL. If there is a failure ofthe active input, the SYSCTL may command the 21D/21D-U OLIU to select theOLIU input.
363-206-295Circuit Pack Descriptions
7-54 Issue 1 December 1997
Protection Circuitry 7
Optional 1+1 nonrevertive unidirectional line protection switching compliant withSONET specifications is provided. The 21D/21D-U OLIU is protection switched bythe SYSCTL in response to an external command, incoming signal failure, orinternal equipment fault. The 21D/21D-U OLIU circuit pack is protection switchedwith the IS-3 line.
The 21D/21D-U OLIU provides selectors for STS-1 and timing signals from theTSI circuit packs. The 21D/21D-U OLIU monitors these inputs and selects one asdirected by SYSCTL.
Fault Detection Circuitry 7

21G/21G-U/21G2-U OLIU Circuit Pack Description 7
Purpose of Circuit 7
The 21G/21G-U/21G2-U OLIU circuit pack performs the optical/electrical conversionbetween the OC-3 and STS-3 signals, multiplexing/demultiplexing between STS-3 andthree STS-1 signals and SONET transport overhead access. The 21G/21G-U/21G2-Ucan be used in either the main or function unit slots in an OC-3 shelf, or the function unitslots only in an OC-12. In the OC-3 shelf, the 21G/21G-U/21G2-U OLIU circuit packalso provides routing of the STS-1s between the OC-3 interface and other main andfunction unit slots in the shelf and will support the STS-1 add/drop feature. In the OC-12shelf, the routing function is performed in the TSI circuit pack.

General Description of Operation 7
The 21G/21G-U/21G2-U OLIU multiplexes three STS-1 signals to an STS-3, inserts theSONET transport overhead bytes (line and section), and scrambles the resulting signal.This STS-3 signal drives the laser transmitter to create the OC-3 output.
The received OC-3 signal is converted back to an electrical STS-3. This STS-3 isdescrambled and demultiplexed to three STS-1 signals, and transport overhead isaccessed. Some of the overhead (for example, section datacom channel) is passed viaserial data links to the control packs, while other bytes (for example framing, paritycheck) are processed on-board. The STS-1 signals go through a pointer processor toguarantee frame alignment to the local system clock before being routed to the othermain and function unit slots.
The 21G/21G-U/21G2-U OLIU provides timing signals to and receives timing signalsfrom the TGS circuit packs.
Fiber access for the 21G OLIU is via a pair of ST lightguide cable connectors from theOLIU faceplate. A faceplate-mounted universal optical connector allows the 21G-U/21G2-U OLIU to accept fiber terminated with ST, SC, or FC connectors. Variouscombinations of buildouts and connectors are also available. See Section 10,"Technical Specifications" for a list of universal buildout attenuators. The 21G/21G-U/21G2-U OLIU photonics comply with SONET long-reach specifications. While single-mode fiber is suggested for optimum performance, multimode facilities are alsosupported.

Transmission Circuitry 7
Transmit Direction. 7The STS-1 router selects three of the STS-1 signals receivedfrom other main and function unit slots, or from TSI slots in the OC-12 shelf, andsends them to the multiplexer. The multiplexer circuitry takes the three STS-1signals from the output of the router, adds SONET transport overhead, then byte-interleaves and scrambles the signal in a frame synchronous scrambler. Theoutput from the multiplexer is in the SONET STS-3 format and is used toamplitude modulate the laser transmitter, which converts the electrical signal to anNRZ-encoded SONET compatible OC-3 optical signal.
Receive Direction. 7In the receive direction, the optical receiver converts the lightpulses from an NRZ-encoded OC-3 signal to equivalent electrical pulses. Theoutput from the optical receiver goes into a timing recovery device. The devicerecovers received clock (155.520 MHz) and uses it to retime the received data.The demultiplexer circuit accepts the retimed STS-3 bit stream, frames on theincoming signal, descrambles it, demultiplexes it into three STS-1 signals, andprocesses SONET transport overhead. The overhead information is sent to theSYSCTL pack via the intra-shelf control bus and the transport overhead channelinterface.
The STS-1 outputs from the demultiplexer are sent to the pointer processor whichperforms pointer interpretation and generation on each received STS-1 using thelocal timing signals. The output of the pointer processor is three STS-1 signals,frame synchronous to each other. The STS-1 router sends each of the threeSTS-1 signals to the appropriate main or function unit in the OC-3 shelf, or TSIslots in the OC-12 shelf.
Control Circuitry 7
The 21G/21G-U/21G2-U OLIU circuit pack interfaces with the system controller(SYSCTL) and with the overhead controller (OHCTL) circuit packs.
The 21G/21G-U/21G2-U OLIU provides maintenance elements for reporting thestatus of the circuit pack, status of the incoming optical and electrical signals, aswell as inventory information (CLEI code, date of manufacture, etc.). Thesemaintenance elements are used by the SYSCTL for fault detection and isolation.Conversely, the OLIU responds to control signals from the SYSCTL such asSTS-1 routing, protection switching, and LED control commands.
The 21G/21G-U/21G2-U OLIU accesses the SONET transport overhead androutes it via the transport overhead channel interface to the AUXCTL slot and/or tothe SYSCTL. The transport overhead is routed from the main slots to both theAUXCTL and SYSCTL slots and from the function unit slots to the AUXCTL slot.
Timing Circuitry 7
Each TGS circuit pack sends timing signals to each OLIU. Each OLIU monitorsthe timing inputs from both TGS circuit packs. The OLIU normally selects thetiming signals from the active TGS circuit pack. Each OLIU provides timing signalsderived from the incoming optical signal to both TGS circuit packs for line(formerly loop) timing and DS1 timing outputs (BITS).

Protection Circuitry 7
Optional 1+1 nonrevertive unidirectional line protection switching compliant withSONET specifications is provided. The 21G/21G-U/21G2-U OLIU is protectionswitched by the SYSCTL in response to an external command, incoming signalfailure, or internal equipment fault. The 21G/21G-U/21G2-U OLIU circuit pack isprotection switched with the optical line.
The 21G/21G-U/21G2-U OLIU interfaces with STS-1 signals from the circuitpacks in the main and function unit slots in an OC-3 shelf, or TSI slots in an OC-12shelf, and selects the signals from the service or protection slot of each pair asdirected by the SYSCTL.
The 21G/21G-U/21G2-U OLIU provides selectors for timing signals from the TGScircuit packs, monitors these inputs, and autonomously selects either one. TheSYSCTL can inhibit autonomous selection and make its own selection.
Fault Detection Circuitry 7
The 21G/21G-U/21G2-U OLIU circuit pack has in-service and out-of-service built-in test capability. In-service testing is continuous and errors are reported whenthey occur to the SYSCTL via the intra-shelf control bus. An out-of-service test isperformed whenever the 21G/21G-U/21G2-U OLIU circuit pack is inserted orrecovers from a transient failure.
Performance Monitoring 7
The 21G/21G-U/21G2-U OLIU provides PM circuitry for the following performanceparameters:
■ Laser bias current threshold (21G and 21G-U only)
■ Transmit optical power threshold (21G and 21G-U only)
■ SEFS
■ Line parameters derived from B2 coding violations.
Power Circuitry 7
Power for the 21G/21G-U OLIU circuit pack is provided by two DC-to-DCconverters located on the 21G/21G-U OLIU circuit pack. One converter supplies+5 volts and the other supplies −5.2 volts. Both A and B −48 volt backplanebusses supply power to the converters through diode ORed circuit pack-mountedpower select circuits and a circuit pack-mounted fuse. Failure of the fuse or eitherconverter causes the red FAULT LED to light.

General Description of Operation 7
The 23G/23G-U OLIU circuit pack provides an interface between an OC-12optical line and 12 STS-1 signals. The 23G/23G-U OLIU provides 24 STS-1 inputports, 12 from service and 12 from protection TSI circuit packs. It selects up to 12STS-1 inputs, performs pointer processing and frame alignment on each STS-1,inserts transport overhead, and combines and scrambles the 12 STS-1 signalsinto an STS-12 (622.08 Mb/s) signal. The 23G/23G-U OLIU then performs anelectrical-to-optical conversion and outputs an OC-12 optical signal fortransmission on an optical fiber.
The 23G/23G-U OLIU receives an optical OC-12 signal and converts it to anelectrical signal. It frames on and descrambles the signal, processes the transportoverhead, and demultiplexes the STS-12 into 12 STS-1 signals. It performspointer processing and frame alignment on each STS-1. The 23G/23G-U OLIUoutputs 24 STS-1 signals, 12 to service and 12 to protection TSI circuit packs.
The 23G/23G-U OLIU performs maintenance and provisioning functionsassociated with the STS-1 and OC-12 inputs and outputs. It provides access tothe line and section overhead in the STS-12 signal and interfaces to the TSI circuitpack at the STS-1 rate and to the optical line at the OC-12 rate. It interfaces to theSYSCTL and OHCTL and sends recovered timing signals to the TGS circuitpacks. The 23G/23G-U OLIU receives its timing signals from the TSI circuit packs.
Fiber access is via a pair of ST (23G) or universal (23G-U) lightguide cableconnectors from the 23G/23G-U OLIU faceplate. Single-mode fiber is suggestedfor optimum performance. The 23G/23G-U OLIU photonics comply with SONETlong-reach specifications.

The 23G/23G-U OLIU, under control of the SYSCTL, normally selects signals from theworking TSI. If a failure of the working clock is detected, the 23G/23G-U OLIU canbe switched to the standby TSI under SYSCTL control. An STS-12 rate clock isgenerated from the STS-1 clock and used in creating the STS-12 signal. Undercontrol of the SYSCTL circuit pack, the 23G/23G-U OLIU selects one group of 12STS-1 signals from either of the 12 active or 12 standby STS-1 inputs.

General Description of Operation 7
The 23H/23H-U OLIU circuit pack provides an interface between an OC-12 opticalline and 12 STS-1 signals and can be used in ring applications. The 23H/23H-UOLIU provides 24 STS-1 input ports, 12 from service and 12 from protection TSIcircuit packs. It selects up to 12 STS-1 inputs, performs pointer processing andframe alignment on each STS-1, inserts transport overhead, and combines andscrambles the 12 STS-1 signals into an STS-12 (622.08 Mb/s) signal. The 23H/23H-U OLIU then performs an electrical-to-optical conversion and outputs anOC-12 optical signal for transmission on an optical fiber.
The 23H/23H-U OLIU receives an optical OC-12 signal and converts it to anelectrical signal. It frames on and descrambles the signal, processes the transportoverhead, and demultiplexes the STS-12 into 12 STS-1 signals. It performspointer processing and frame alignment on each STS-1. The 23H/23H-U OLIUoutputs 24 STS-1 signals, 12 to service and 12 to protection TSI circuit packs.
The 23H/23H-U OLIU performs maintenance and provisioning functionsassociated with the STS-1 and OC-12 inputs and outputs. It provides access tothe line and section overhead in the STS-12 signal and interfaces to the TSI circuitpack at the STS-1 rate and to the optical line at the OC-12 rate. It interfaces to theSYSCTL and OHCTL and sends recovered timing signals to the TGS circuitpacks. The 23H/23H-U OLIU receives its timing signals from the TSI circuit packs.
Fiber access is via a pair of ST (23H) or universal (23H-U) lightguide cableconnectors from the 23H/23H-U OLIU faceplate. Single-mode fiber is suggestedfor optimum performance. The 23H/23H-U OLIU photonics meets SONET longreach specifications. The 23H/23H-U is not hardened for uncontrolledenvironments and is used in CO applications.
For 23H applications requiring external optical attenuators, the faceplate-mountedtransmit (OUT) connector is designed to accept a lightguide buildout. Availablebuildouts are A3010B - 5 dB, A3010D - 10 dB, and A3010F - 15 dB. For loopbacktesting requiring 19 dB attenuation, use the 4C Test Cable. For 23H-Uapplications, see Section 10, "Technical Specifications," for a list of universalbuildout attenuators.

Detailed Description of Operation 7
Transmission Circuitry 7
Transmit Direction. 7Figure 7-29 is a functional block diagram of the 23H/23H-UOLIU. The 23H/23H-U OLIU receives an STS-1 rate clock and an associatedframe pulse from each of the working and standby TSI circuit packs. The 23H/23H-U OLIU, under control of the SYSCTL, normally selects signals from theworking TSI. If a failure of the working clock is detected, the 23H/23H-U OLIU canbe switched to the standby TSI under SYSCTL control. An STS-12 rate clock isgenerated from the STS-1 clock and used in creating the STS-12 signal. Undercontrol of the SYSCTL circuit pack, the 23H/23H-U OLIU selects one group of 12STS-1 signals from either of the 12 active or 12 standby STS-1 inputs. The 23H/23H-U OLIU performs pointer processing and frame alignment and adds transportoverhead to the selected STS-1 signals. The 23H/23H-U OLIU provides access tothe transport overhead which is sent to and received from the OHCTL.

The STS-1 signals are byte-interleaved and scrambled in a frame synchronousscrambler to produce a SONET format compatible STS-12 signal. The STS-12signal is used to amplitude modulate a laser transmitter to convert the electricalsignal to an NRZ-encoded SONET compatible OC-12 optical signal.
Receive Direction. 7The 23H/23H-U OLIU circuit pack receives an OC-12 opticalsignal that is an NRZ-coded SONET compatible signal. An optical receiverconverts the optical OC-12 signal to an electrical STS-12 signal. An STS-12 rateclock is recovered and used to retime the data.
The 23H/23H-U OLIU frames on the retimed STS-12 data, demultiplexes it into 12STS-1 signals, and provides the transport overhead access.
The 23H/23H-U OLIU performs pointer interpretation, frequency justification, andpointer generation on each of the STS-1 signals, using the local clock and framefrom the selected TSI circuit pack. The result is 12 STS-1 signals that are framesynchronous with each other and with the local clock and frame sync.
Each STS-1 signal is bridged to the service and protection TSI circuit packs.
The 23H/23H-U OLIU sends a clock derived from the recovered receive clock tothe TGS circuit packs for loop timing. The 23H/23H-U OLIU provides transportoverhead access in the receive direction.
Control Circuitry 7
The 23H/23H-U OLIU circuit pack interfaces with the SYSCTL and the OHCTLcircuit packs.
Control and Maintenance Functions. 7The 23H/23H-U OLIU providesmaintenance elements for reporting the status of the circuit pack and the incomingSTS-1 and OC-12 signals to the SYSCTL. Conversely, the 23H/23H-U OLIUresponds to control signals from the SYSCTL.
■ SYSCTL: The 23H/23H-U OLIU communicates with the SYSCTL circuitpack via a control interface. The 23H/23H-U OLIU provides maintenanceelements for reporting the status of the circuit pack and the incoming STS-1 and OC-12 signals. These maintenance elements are used by theSYSCTL for fault detection and isolation. Conversely, the 23H/23H-U OLIUresponds to control signals from the SYSCTL, such as LED and protectionswitching controls.
■ Transport Overhead Channel Interface: The 23H/23H-U OLIU accessesthe SONET overhead and routes this data to the OHCTL.
363-206-295Circuit Pack Descriptions

Timing Circuitry 7
Each TGS circuit pack sends timing signals to the 23H/23H-U OLIU circuit packvia the TSI circuit packs.
The 23H/23H-U OLIU circuit pack sends a clock signal to both TGS circuit packsfor loop timing.
Protection Circuitry 7
The 23H/23H-U OLIU provides STS-1 data path selectors for implementing a 1x1protection switch between TSI circuit packs. The selectors are controlled by theSYSCTL.
The 23H/23H-U OLIU is protection switched by the SYSCTL in response to faultindications on the 23H/23H-U OLIU, or in response to fault indications on atransmission circuit pack with which it interfaces, or in response to externalcommands.
Fault Detection Circuitry 7
The 23H/23H-U OLIU circuit pack has in-service and out-of-service built-in testcapability. In-service device testing is continuous, and errors are reported to theSYSCTL when they occur via the intra-shelf control bus. Incoming and outgoingoptical power thresholds are also monitored.
There is no electrical loopback in the 23H/23H-U OLIU. All loopbacks are externaloptical loopbacks which require an attenuator.
Performance Monitoring 7
The 23H/23H-U OLIU provides PM circuitry for the following maintenanceparameters:
■ Parity error counts
■ Incoming OC-12 OOF
■ Outgoing OC-12 laser bias current threshold
■ Line parameters based on B2 coding violations.
Power Circuitry 7
The 23H/23H-U OLIU circuit pack uses board-mounted DC-DC power convertersthat convert −48 V received from the backplane to +5 V, −5.2 V, +15 V, and −2.3 Vfor use on the circuit pack. The 23H/23H-U OLIU interfaces with both the A and Bfeeders and provides a "diode-ORed," so that loss of one feeder will not affect the23H/23H-U OLIU. A fuse element is provided at the −48 V input to the DC-DCconverter.

Overview 8
This section describes the administration and provisioning features of theDDM-2000 OC-12 Multiplexer. The following topics are described in addition tothe administration and provisioning features:
■ Multiplexing and mapping
■ Cross-connection provisioning for ring networks
■ Listing of provisionable parameters with their ranges and default values.
Administration 8
Version Recognition 8
The DDM-2000 OC-12 Multiplexer provides automatic version recognition of allhardware, firmware, and software installed in the system. Each circuit pack CLEI*
code, equipment catalog item (ECI) code, apparatus code and series number, andserial number is stored on the circuit pack and is accessible by the systemcontroller via the craft interface terminal (CIT). Circuit packs with socketed devicesalso report those devices and program identification (PID) codes. The systemcontroller (SYSCTL) also reports the software version for the system. Refer to thertrv-eqpt command in Section 11, "Commands and Reports."

Security 8
DDM-2000 OC-12 Multiplexers provide security capabilities to protect againstunauthorized access to the system through the CIT, data communications channel(DCC), and TL1/X.25 interfaces. When security is enabled (default is disabled forthe CIT and DCC and always enabled for TL1/X.25), four types of users areallowed access to the system with a valid login and password:
■ Privileged users can execute all commands
■ General users can execute any commands not restricted to privilegedusers
■ Maintenance users can execute some of the general level and all “reports-only” commands that are not restricted to priviliged users
■ Reports-only users can only execute commands that retrieve reports fromthe system.
When the system is first initialized, three default logins and passwords areprovided which must be changed by a privileged user before security is enabled.At initialization, privileged users are those users who use the default logins andpasswords. Replacement of the SYSCTL circuit pack causes the system to defaultback to the default logins and passwords. Up to 100 logins and passwords can beadded, deleted, and changed by three authorized privileged users. Login andpassword security can be enabled or disabled. Timeouts can be provisionedindependently for front and rear access CIT interfaces and the synchronousoptical network (SONET) section DCC. Timeout is disabled on the TL1/X.25interface. For more information on provisioning, see “System Turnup/CircuitOrder,” in the TOP section of this manual (Volume II).
Authorized privileged users can establish general user and reports-only userlogins using the set-lgn command. Authorized privileged users can also"lockout" access by general and reports-only users without deleting the login andpassword file.
The following commands are restricted to privileged users over the CIT and DCCinterfaces. See 824-102-151, DDM-2000 Multiplexers Operations SystemsEngineering Guide for TL1/X.25 command access privileges.
■ init-sys — Initialize System
■ rstr-passwd — Restore login and password file
■ rtrv-lgn — Retrieve Login
■ rtrv-passwd — Retrieve login and password file
■ set-feat — Set Features
■ set-fecom — Set Far-End Communications
363-206-295Administration and Provisioning
Issue 1 December 1997 8-3
■ set-lgn — Set Login
■ set-secu — Set Security
■ set-sync — Set Synchronization characteristics.
When security is enabled (default is “disable”), the following additional commandsbecome restricted to privileged users only:
■ apply — Locally Overwrite Executing Software
■ cpy-prog — Copy Program
■ dlt-osacmap — Delete OS application context ID map
■ ent-osacmap — Enter OS application context ID map
■ ent-tl1msgmap — Enter TL1 message map for OS
■ ent-ulsdcc-l3 — Enter Upper Layer Section DCC - Layer 3
■ ent-ulsdcc-l4 — Enter Upper Layer Section DCC - Layer 4

■ init-pm — Initialize Performance Monitoring
■ ins-prog — Install Program
■ reset — System Reset
■ set-date — Set network element (NE) Date and time
■ set-ne — Set NE name.
■ set-x25 — Set X.25 baud rate for OS.
Reports-only users can execute the following commands: ? (help), logout,rlgn, set-passwd (their own), toggle, and all rtrv commands except,rtrv-lgn, and rtrv-passwd.
For details on these and other commands, see Section 11, "Commands andReports."

Software Upgrades 8
The DDM-2000 OC-12 Multiplexer provides an in-service software installationcapability to update the generic program in local and remote systems. Upgradesare distributed on MS-DOS * formatted diskettes containing the new software andan installation program. An enhanced software download feature allows thesource NE to download compressed copies of the new generic to all the othernodes in the network. This downloaded software will remain inactive until theapply command is issued to overwrite the current software. This feature allowswide flexibility in scheduling upgrades throughout the network. These softwareupgrades are the primary mechanism to add new feature enhancements to the in-service DDM-2000 OC-12 network.
The ins-prog command supports software installation from a personalcomputer (PC) and the cpy-prog command supports software installation fromone shelf to another shelf. For details on these and other commands, see Section11, "Commands and Reports."
Remote Software Download and Copy 8
System software can be downloaded using a PC through the EIA-232-D interfaceon the user panel to another system connected to the local system via the SONETDCC. The DDM-2000 OC-3 and OC-12 Multiplexers can upgrade the systemsoftware while in-service. DDM-2000 OC-3 and OC-12 Multiplexers use flasherasable programmable read-only memory (flash EPROM) chips to provide thiscapability. Software can be downloaded from a PC to a remote NE even when thelocal shelf is a different member of the DDM-2000 product family or SLC-2000from the remote shelf (for example, a DDM-2000 OC-12 at the CO and a DDM-2000 FiberReach at the RT site). Remote software download and copy is alsosupported in multi-vendor subnetworks, but only between DDM-2000 Multiplexers.The remote software download and copy capabilities enable the network serviceproviders to avoid costly craft dispatches for software upgrade.
DDM-2000 can also accept software downloads from Lucent’s ITM SNC R5.0when upgrading from DDM-2000 OC-3 R13.0 and OC-12 R7.0 to subsequentreleases.
Software Compatibility 8
DDM-2000 OC-12 Release 7.0 is NOT compatible with previous releases ofDDM-2000 OC-12. Therefore, when upgrading a subnetwork, care should betaken to avoid isolating NEs that have not yet been upgraded to Release7.0.Controller Maintenance and Memory Administration

Controller Maintenance 8
The controller for the DDM-2000 OC-12 Multiplexer consists of the SYSCTL andOHCTL circuit packs. The SYSCTL circuit pack provides CIT interfaces andcoordinates protection switching, as well as all shelf maintenance andprovisioning activities. The OHCTL circuit pack provides an X.25 interface and acommunications channel to remote shelves via the DCC bytes in the OC-Nsection overhead. Both circuit packs have a processor and both have volatilerandom access memory (RAM) and nonvolatile memory.
The DDM-2000 OC-12 Multiplexer is designed so that SYSCTL failures do notaffect transmission. That is, no hits or errors will occur on any traffic as a result ofa SYSCTL circuit pack failure. A SYSCTL failure does result in the loss ofautomatic protection switching. However, if a transmission circuit pack fails beforea SYSCTL failure, the protection switch will remain effective during the SYSCTLfailure and service is preserved. This means that if an active transmission circuitpack should fail while the SYSCTL is failed, a protection switch cannot be doneand service carried by the failed circuit pack will be affected.
Memory Administration 8
All transmission affecting parameters that are set by software are stored innonvolatile memory on the SYSCTL circuit pack and on the appropriatetransmission circuit packs. When the shelf is powered up or the SYSCTL circuitpack is replaced, the shelf's transmission values are automatically uploaded to theSYSCTL. When a transmission circuit pack is replaced, provisioning data storedon the SYSCTL is automatically downloaded to the replacement circuit pack.Manual action is not required to maintain system provisioning after a circuit packis replaced.
Certain non-service-affecting provisioned data, such as alarm delay are storedonly on the SYSCTL circuit pack. This means that when a SYSCTL circuit pack isreplaced, the new SYSTCL circuit pack should be initialized by pressing the INITbutton during the 10-second interval while the CR alarm LED is flashing after theSYSCTL circuit pack is inserted. This action is the same as entering the init-sys:sysctl command which sets the SYSCTL circuit pack parameters to theirdefault values. Refer to the init-sys command in Section 11, "Commands andReports," and to "Install or Replace SYSCTL," in the TOP section of this manual(Volume II). If parameters other than the default values are needed, the valuesmust be entered using the CIT. If the INIT function is not performed, whatevervalues that are stored in nonvolatile memory on the new SYSCTL circuit pack areused. Failure to follow the proper procedure may not cause transmission errors orloss of service but could affect maintenance. For example, an invalid TID couldproduce confusing TL1 reports to the OS.

System Backup and Restoral 8
The CPro-2000 Graphical User Interface (GUI) and Provisioning Tool includes a backupand restoral feature to protect provisioning information in ring networks. This featuresaves a copy of a node's provisionable parameters so they can be restored at a later date,if necessary.
The feature provides backup and restoral for all provisionable parameters including:
■ Network Element (NE) provisionable parameters
■ Cross-connections
■ Port and line provisionable parameters
■ Performance Monitoring (PM) threshold parameters
Refer to Section 6, “Operations Interfaces,” of this manual for more information onCPro-2000. See also 365-576-130, CPro-2000 User Manual, Release 7.0, for moreinformation on CPro-2000.
ITM SNC 8
All of the above backup and restore features are also available with the IntegratedTransport Management SubNetwork Controller (ITM SNC), Release 5.0. Refer to107-564-270, Integrated Transport Management (ITM) SubNetwork Controller (SNC),User Guide, for additional information.
Service-Affecting Actions 8
Although the DDM-2000 OC-12 Multiplexer is designed to minimize LOS due toequipment failure or human action, there are certain controller related actions that cancause a loss of provisioning data and possibly LOS. These actions include:
■ Replacing a transmission circuit pack when the SYSCTL is failed or removed canresult in a loss of provisioning data and LOS
■ Replacing a transmission circuit pack in a shelf without power can result in a lossof provisioning data. LOS may continue on channels associated with the replacedcircuit pack after the shelf is powered up.
■ Executing the command init-sys:all sets all provisioning data, includingcross-connect provisioning to default values. This causes LOS on any channelconnected with nondefault cross-connections.
■ Failing to disable the SYSCTL circuit pack before it is removed in accordance withTOP procedures. Failure to follow the procedure could result in unexpected events;however, no LOS occurs. Refer to the "Install or Replace SYSCTL" procedure inthe TOP section of this manual (Volume II).
■ Provisioning data is maintained through a software download to the SYSCTL.Replacing the SYSCTL circuit pack with incompatible software and intentionallyoverriding the software check could result in a loss of data.

Multiplexing and Mapping 8
The following paragraphs describe DS3 to OC-12, OC-3 to OC-12, EC-1 toOC-12, and OC-3c to OC-12 (feature package option) multiplexing and mapping.
DS3 to OC-12 8
Each DS3 signal received by a 3DS3 circuit pack is mapped to an STS-1 signalvia the asynchronous mapping as specified in the SONET standard. The threeSTS-1 signals associated with a 3DS3 circuit pack are then multiplexed with theSTS-1 signals from the other function units to form the STS-12 high-speed signal.The STS-12 signal is then converted to an OC-12 signal for transport on the high-speed optical line.
In the reverse direction, a received OC-12 signal is converted to an electricalSTS-12 signal which is demultiplexed to 12 STS-1 signals. The STS-1 signals arerouted to the function units where they are converted back into DS3 signals by the3DS3 circuit packs.
OC-3 to OC-12 8
When a function unit is equipped with a 21-type OLIU circuit pack, the receivedoptical signal is converted to an electrical STS-3 signal which is demultiplexed intothree STS-1 signals. The three STS-1 signals are multiplexed with the STS-1signals from the other function units to form an STS-12 signal, which is convertedto an OC-12 signal for transport on the OC-12 line.
In the reverse direction, the received OC-12 signal is converted to an electricalSTS-12 signal which is demultiplexed to 12 STS-1 signals. The STS-1 signals arerouted to the function units where they are multiplexed to an STS-3 signal, whichis converted to an OC-3 optical signal for transport on the optical line.
When the function unit service and protection slots are equipped with OLIUs, theycan be provisioned as ring (0x1) low-speed interfaces or linear (1+1) opticalextensions using the set-oc3 command. The cross-connections can then bemade using the ent-crs-sts1 command. See Section 11, "Commands andReports," for more information on this provisioning.

OC-3c to OC-12 (Optional Feature) 8
This application is a feature package option which must be enabled using theset-feat command.
A function unit can be optionally equipped with 21-type OLIUs for OC-3ctransport. The incoming OC-3c signal is electrically converted into an STS-3csignal. Four STS-3c or a mix of STS-3c and STS-1 signals are multiplexed into anSTS-12 signal and converted into an OC-12 signal for transport over the OC-12line.
When the function unit service and protection slots are equipped with OLIUs, theycan be provisioned as ring (0x1) low-speed interfaces or linear (1+1) opticalextensions using the set-oc3 command. The cross-connections can then bemade using the ent-crs-sts3c command. See Section 11, "Commands andReports," for more information on this provisioning.
EC-1 to OC-12 8
The 3STS1E low-speed interface receives an EC-1 signal from the backplanecoaxial connector which is then routed as an internal STS-1. This signal is STS-1cross-connected to the OC-12 interface. At the OC-12 interface, these internalSTS-1 signals are multiplexed into an STS-12 and converted to an optical OC-12signal.
Cross-connections are made using the ent-crs-sts1 command. See Section11, "Commands and Reports," for more information on this command.
In the opposite direction, a received OC-12 is converted into an electrical STS-12and demultiplexed. After STS-1 cross-connections, the resulting STS-1 internalsignal is converted to an EC-1 signal by the 3STS1E interface. The following areexamples of STS-1 cross-connections in ring networks:

Provisioning 8
The DDM-2000 OC-12 Multiplexer allows the user to customize many systemcharacteristics through its provisioning features. Provisioning parameters are setby a combination of on-board switches and software control.
Parameters likely to vary from installation to installation (for example, DS3 LBOs)and parameters that will not change in service (for example, OC-3 optical power)are set with on-board switches. This allows installations to be performed without aCIT using default provisioning values and switch settings. Other parameters thatrequire a wide range of options or in-service changes are set under softwarecontrol. For example, PM thresholds can be customized for each installation usingthe CIT.
Default Provisioning 8
Installation provisioning is minimized with default values set in the factory. Eachparameter is given a default. The defaults for software parameters are maintainedin the SYSCTL circuit pack. All provisioning data is stored in nonvolatile memoryto prevent data loss during power failures.
Remote Provisioning 8
Software control of many provisioning parameters allows remote provisioning ofthe DDM-2000 OC-12 Multiplexer. This feature is provided especially forparameters likely to change in service, in support of centralized operationspractices.
Automatic Provisioning 8
Circuit Pack Replacement 8
Replacement of a failed circuit pack is simplified by automatic provisioning of thecurrent circuit pack values. The SYSCTL circuit pack maintains a provisioningmap of the entire shelf, so when a transmission or synchronization circuit pack isreplaced, the SYSCTL circuit pack automatically downloads values to the newcircuit pack. If the SYSCTL circuit pack is ever replaced, provisioning, for example,transmission data, except for the LBO settings, from every other circuit pack in theshelf is automatically uploaded to the nonvolatile memory of the new SYSCTLcircuit pack.

Feature Package Provisioning 8
Certain software features are available only through a special licensing agreementwith Lucent Technologies. The OC-3c (STS-3c) feature is enabled by privileged-user logins according to the licensing agreement, using the set-feat commandand can be reviewed using the rtrv-feat command. This feature is optionaland may not be active on all systems. For details on these and other commands,refer to Section 11, "Commands and Reports."
Data Communications Channel (DCC)Provisioning 8
The DCC is automatically provisioned in the following manner and needs noprovisioning by the user. The DCC uses the SONET overhead to communicatebetween NEs and follows the active SONET transmission line and/or IAO LAN.
In a given subnetwork, the NEs on each side of an optical span must have their"user-side/network-side" (OSI terminology) parameters provisioned to oppositevalues. Local procedures should determine the "user" and "network" side of aspan. For example, the CO terminal can be designated the network side and theRT site the user side. It does not matter as long as the two sides are oppositevalues. See the TOP section of this manual (Volume II) for OI provisioningprocedures.
■ In rings, there is one DCC assigned for the "m1" ring and another DCC forthe "m2" ring.
■ When function unit slot pairs are provisioned for linear (1+1) applications(connected to OC-3 linear extensions), there is one DCC for each pair.When provisioned for ring (0x1) applications, there is one DCC for eachslot.

Operations Interworking (OI) Provisioning 8
OI provides the capability to access, operate, administer, maintain, and provisionremote Lucent NEs from other NEs in a subnetwork or from a centralized OS.
OI is supported among systems that are connected through the DCC. Table 8-1lists the SONET software compatibility within a subnetwork for the Lucent 2000Product Family systems. All configurations listed support OI. The table lists allpossible software combinations. Combinations not listed are not supported.
Table 8-1. OI Software Compatibility
OI features include the following:
■ Remote OS access (via TL1/X.25 GNE)
■ Remote CIT login (remote technician access)
■ Remote software download and copy
See also 824-102-144, Lucent Technologies 2000 Product Family Multi-VendorOperations Interworking Guide.
NSAP Provisioning 8
The network services access point (NSAP) is a multiple part address thatuniquely identifies each NE for OI purposes. The NSAP is used for subnetworkDCC communications using the OSI protocol. A unique NSAP is programmed intothe SYSCTL circuit pack at the factory and does not have to be modified by theuser unless subnetwork partitioning is necessary. This default NSAP value isadequate to operate typical subnetworks.
Subnetwork partitioning is accomplished by assigning NEs to different areas. AnNE’s area address is one of the subfields within its NSAP. The ent-ulsdcc-l3command is used to modify an NE’s NSAP. See the ent-ulsdcc-l3 commandin Section 11, "Commands and Reports," for more information on NSAPprovisioning.

TARP Provisioning 8
Although TARP functions automatically, using standard default values and withoutany user provisioning, DDM-2000 allows provisioning of the following TARPparameters. All TARP parameters are provisioned by the CIT and TL1 ent-ulsdcc-l4” command and include the following:
■ Lifetime
■ Manual Adjacency
■ Timers
■ Loop Detection Buffer (LDB) Flush Timer
■ TDC Enable/Disable
■ TDC TID-NSAP Entries
It is recommended that TARP default values always be used, with the possibleexceptions of Manual Adjacency and the TDC parameters. TARP ManualAdjacency may be used to propagate TARP messages beyond any non-TARPnodes in a subnetwork, if necessary. In the unlikely event the TDC containsinaccurate information, the TDC parameters may be used to update the TDC.
Eliminated Provisioning: Because DDM-2000 OC-12 Release 7.0 does notsupport Lucent Directory Services (LDS) or Remote NE Status features, thefollowing OI-related provisioning is no longer necessary:
■ AGNE
■ Alarm Group Number
■ DSNE
■ DSNE DLT-TADRMAP (CIT and TL1 command)
■ NE Number
■ Site Number
■ TBOS Number
Level 2 Provisioning 8
Subnetwork partitioning also involves the assignment of level 2 IntermediateSystems (ISs). The ent-ulsdcc-l3 command is used to assign DDM-2000 toserve as a level 2 IS. See the ent-ulsdcc-l3 command in Section 11,"Commands and Reports," for more information on NSAP provisioning.

Port State Provisioning 8
Port state provisioning is a feature provided on DDM-2000 OC-12 Multiplexersthat suppresses alarm reporting and PM by supporting multiple states (automatic[AUTO], in-service [IS], and not-monitored [NMON]) for DS3 and EC-1 ports.
Ports without signals (undriven) are in the AUTO state until changed to the ISstate when a signal is present. The set-state-t3 and set-state-ec1commands allow a user to change the state of a port to the NMON state or fromthe NMON state to the AUTO state. The rtrv-state-eqpt, rtrv-t3, andrtrv-ec1 commands allow a user to retrieve current port states. The updcommand allows a user to change the port state of all undriven ports from IS toAUTO.
Channel State Provisioning 8
Channel state provisioning is a feature provided on DDM-2000 OC-12Multiplexers that suppresses reporting of alarms and events for STS-1 channelsby supporting multiple states at the OC-12 ports (AUTO, IS, and NMON) for thesechannels. The rtrv-state-sts1 command allows a user to retrieve currentchannel states.
While an end-to-end circuit is being set up, particularly during STS-1 cross-connection provisioning, transient maintenance signals may result. Withoutautomatic channel state provisioning, these are reported as alarms or events. Thetechnicians are expected to ignore these transient alarms and initiate correctiveaction only if the alarms persist after the provisioning is completed.
To avoid the confusion created by this, DDM-2000 OC-12 Multiplexers provideautomatic channel state provisioning. An STS-1 channel stays in the defaultAUTO state until a valid signal, a framed signal that is not alarm indication signal(AIS) or unequipped is received on that channel. While in AUTO state, no alarmsor events are reported on the channel by the DDM-2000 OC-12 Multiplexer. Onreceiving a valid signal, which occurs when the end-to-end circuit is completelyprovisioned, the channel automatically changes to the IS state, and normal alarmand event reporting starts. An additional state, NMON, is also supported in whichalarm and event reporting is suppressed regardless of the validity of the signalbeing received on the channel. Like the port state provisioning capability providedfor DS3 and EC-1 ports, the user can use CIT or TL1 commands to manuallychange a channel from IS or AUTO to NMON, and from NMON to AUTO. A directchange from NMON to IS is not allowed. See the set-state-sts1, rtrv-state-sts1 and upd commands.

Line State Provisioning 8
Line state provisioning is a feature provided on DDM-2000 OC-12 Multiplexers thatsuppresses alarm reporting and PM by supporting multiple states (IS and NMON) forOC-3 lines. See the set-state-oc3 and rtrv-state-oc3 commands.
Remote OS Access (TL1/X.25 GNE) 8
A DDM-2000 subnetwork may have one or more NEs serving as TL1/X.25 GNEs.Without any user provisioning, a DDM-2000 is automatically a GNE upon connecting anX.25 link to its X.25 interface. Refer to the “TL1/X.25 Interfaces” paragraph in Section 6,“Operations Interfaces,” for more information.
Remote CIT Login 8
Each DDM-2000 Multiplexer can remotely log into other DDM-2000 Multiplexers in thesame subnetwork. OI also allows remote logins between DDM-2000 and the SLC-2000Access System and from the FT-2000 OC-48 Lightwave System to other Lucent 2000Product Family systems in the same subnetwork. Refer to Section 6, “OperationsInterfaces,” for more information.
Remote Software Download and Copy 8
The DDM-2000 OC-3 and OC-12 Multiplexers can upgrade the system software whilein-service. Software can be downloaded locally using a PC through the EIA-232-Dinterface on the user panel or remotely over the SONET DCC. Refer to the “SoftwareUpgrades” section at the beginning of this chapter for more information.
Subnetwork Size 8
There is no limitation on the size of the networks formed by splitting a large network intoa number of smaller maintenance subnetworks by disabling the DCC between thesubnetworks. Subnetwork partitioning can be done while in service without affectingtraffic. Subnetwork sizes of up to 256 NEs are supported via subnetwork partitioning(50 per level 1 area, 256 per subnetwork) with multiple areas connected via level 2Intermediate Systems (IS). Refer to 824-102-144, Lucent Technologies 2000 ProductFamily Multi-Vendor Operations Interworking Guide, for additional information.

Cross-Connection Provisioning 8
Cross-Connection Types 8
DDM-2000 OC-12 Multiplexers have time slot interchange (TSI) features. This offersusers flexibility in directing traffic in and out of these systems to support a wide varietyand range of customer applications.
The DDM-2000 OC-12 Multiplexer can be provisioned for cross-connect routing ofsignals. For rings, STS-1 signals may be manually cross-connected in several ways. Forbidirectional drop services, the normal "twoway" cross-connection is used to connect asignal in the high-speed slot to any available time slot in any function unit equipped withlow-speed 3STS1E or 3DS3 circuit packs.
Ring (0x1) Cross-Connections 8
For ring (0x1) interfaces, a manual "twoway" cross-connection command(ent-crs-sts1) is used to connect a signal in the high-speed slot to one or bothfunction unit slots equipped with 21-type OLIU circuit packs.
Video Cross-Connections 8
For video cross-connections at central office video (COV) and remote terminal video(RTV) sites, an incoming STS-3c signal from each function unit slot equipped with 21-type OLIUs are connected to ring 1 and ring 2 respectively in a one-way unprotectedmode. This provides up to eight different STS-3c signals on the ring.
For video cross-connections at RT site applications, up to four incoming STS-3c signalsfrom ring 1 and four from ring 2 are dropped to FN ()-1 and FN ()-2 slots respectivelyand continued on both rings to the next node.
The primary commands associated with these cross-connections are:
■ The set-oc3 command has a parameter for identifying this application
■ The ent-crs-sts3c command has parameters for identifying either COV orRTV nodes
■ The set-state-oc3 command is used to set unused input ports of the functionunit OLIUs at RTV sites to the NMON state to prevent optical alarms.
Drop and Continue Cross-Connections 8
End-to-end survivable service facilities need to cross multiple rings interconnected atmultiple (dual) wire centers. To support these applications, a drop-and-continue cross-connection is provided for a signal from a high-speed channel to be dropped to aspecified low-speed port or channel and continued on to the next node in the same
363-206-295Administration and Provisioning
8-16 Issue 1 December 1997
direction while also adding a corresponding signal from the low-speed port orchannel to the high-speed channel in the other rotation of the ring.
Drop and continue cross-connections are used in DRI applications. Drop andcontinue cross-connections are only allowed if the function units are equippedwith 3STS1E, 3DS3, or 21-type OLIUs. If OLIUs are used, the function unit slotsmust be provisioned as linear (1+1).
The "drop and continue" cross-connection provides, in a single command(ent-crs), the proper bidirectional cross-connection to "drop" a copy of the high-speed signal in the main-B slot to any available time slot in any function unit and to"continue" the signal on the high-speed channel to the next node. The samecommand also properly drops the signal from the opposite ring direction.
Pass-Through Cross-Connections 8
Pass-through cross-connections allow a high-speed STS-1 or STS-3 channel tobe "passed-through" between two high-speed ring interfaces. This is used in allpath switched ring applications at nodes where traffic is not dropped.
In path switched rings, pass-through grooming (passing a signal on a ring timeslot that is different from the ring time slot on which it was received) is notsupported. The bidirectional pass-through cross-connection is used to connectthe high-speed signal from one side of the ring to the other side. Both rings areproperly connected, using a single "twoway" (ent-crs) command. The high-speed time slot address entering must be the same time slot address leaving inpass-through connections.
Manual OC-12 Ring Cross-Connections 8
Cross-connections in DDM-2000 OC-12 Multiplexers are made by specifying theSONET rate (STS-1 or STS-3c), the end point addresses (access identifiers), thecross-connection type (twoway, drop and continue, etc.) and, in some cases, thering direction (ring=mb1, ring=mb2, etc.). In DDM-2000 OC-12 Multiplexers, eachsingle cross-connection command establishes a two-way cross-connection.
All nodes in the ring must be provisioned for STS-1 or STS-3c cross-connections.Refer to Section 11, "Commands and Reports," for more information on thesecommands.
DDM-2000 OC-12 rings provide flexible routing of STS-1 or STS-3c signalsbetween high-speed and function unit interfaces. These "manual" cross-connections are entered using the CIT and are shown in Table 8-2 throughTable 8-9. These cross-connection types can be "mixed and matched" in a singlesystem (for example, STS-1s, STS-3cs, pass-through and drop and continue).

OC-12 Ring Network Cross-Connection Example 8
The following paragraphs describe a ring network example configuration anddescribe how to create manual cross-connections to establish the ring network.The example configuration is a ring network with two ring fibers and six nodes.Ring 1 carries ring traffic in the clockwise direction while Ring 2 carries ring trafficin the counterclockwise direction. For the purposes of this example, it is assumedthat each shelf has recently been installed, equipped with 23G/23G-U or 23H/23H-U OLIUs in the main-B1 and main-B2 slots and 3DS3s in the function unitslots, and all shelves are properly installed and provisioned. This example is forDS3 services. See "System Turnup/Circuit Order" in the TOP section of thismanual (Volume II). Figure 8-1 shows the six nodes with dashed lines, indicatingthe cross-connections.
Ring configurations support manual STS-1 cross-connections. Manual cross-connections must be made at each node in the network for each circuit beingestablished. Drop cross-connections are made at the drop nodes where serviceenters or exits the node (Nodes 1 and 5), and pass-through cross-connections aremade at each intermediate node (Nodes 2, 3, 4, and 6).
The example is for DS3 services but can be used for STS-1 services if thefunction units are properly equipped with 3STS1E circuit packs. The 3STS1Ecircuit pack can support three STS-1 cross-connections.
Pass-through cross-connections may be established first to minimize alarms. Theexample assumes that the drop cross-connections are made shortly after thepass-through cross-connections are made. This is the preferred method, since itassures that all cross-connections are associated with services.
An alternate method is also possible. Before service is established, all shelvescan be defaulted to set up all pass-through cross-connections in the ring. Thismethod has the advantage of only having to delete pass-through and establishdrop cross-connections at the add/drop nodes. However, this method mayintroduce the possibility of affecting service when cross-connections are deleted.This is because it will not be possible to distinguish between pass-through cross-connections that are in use carrying service from those that are available. Use ofthis default pass-through provisioning method is only recommended if theaccuracy of the cross-connection information on the work order is assured.
The following commands may be used to delete, enter, and retrieve cross-connections: dlt-crs-sts3c, ent-crs-sts3c, rtrv-crs-sts3c, dlt-crs-sts1, ent-crs-sts1, and rtrv-crs-sts1. See Section 11,"Commands and Reports," for a description of these commands.
363-206-295Administration and Provisioning
8-22 Issue 1 December 1997
It is important that the pass-through signal is assigned the same channel addressfor all nodes in the ring, including the add/drop nodes mb-1 in the example.
Do the following procedure:
1. Using the work order, identify the TIDs of the entry and exit points on thering (Nodes 1 and 5 in the example).
2. Determine if the work order is specifying use of a particular ring channel(some work orders may abbreviate the mb designation as m1). If the workorder does not designate an STS-1 ring channel to use, use the rtrv-crs-sts1:all; to identify all unused ring channels. The output reportwill show only active cross-connections. In the example, we will cross-connect a DS3 from Node 1 through the ring and drop the DS3 at Node 5using mb-1.
3. Log in or remote log in to all the TIDs that are not entry and exit points(intermediate nodes) and enter ring "pass-through" cross-connections. Ateach intermediate node of the network, use the ent-crs-sts1:command to cross-connect the DS3 channel time slots between main B-1and main B-2. For example, to cross-connect the channel time slotsassociated with STS-1 #1, use the ent-crs-sts1:mb-1,mb-1command.
NOTE:Address 1 and address 2 must be the same.
4. Log in or remote log in to each drop node and enter the "drop" cross-connection. At both drop nodes of the DS3 circuit being established, usethe ent-crs-sts1: command to cross-connect the DS3 channel timeslot to the proper group, slot, and port; for example,ent-crs-sts1:mb-1,a-1.
NOTE:Only one command is required to establish the drop cross-connections on both rings between main B and Fn-A. At exit nodes,assuming normal operation, the same signal is present on bothrings. The system monitors the input from each ring and selects oneto drop to Fn-A.

5. Status and alarm conditions can be present during the provisioningoperation but will clear once the last ring cross-connection for this DS3service is completed. If they do not, the rtrv-alm; and rtrv-crs-sts1; commands can be used to isolate the problem (see the TOPsection of this manual [Volume II]).
6. Log in or remote log in to all the nodes and verify appropriate drop or pass-through ring cross-connections.
7. Test both paths around the ring. Since DDM-2000 OC-12 uses non-revertive path switching to minimize the number of hits on services, theinitial path selection is arbitrary. Use rtrv-state-path and sw-path-sts1 commands to test both ring paths around the ring network at the dropnodes of the new service. The sw-path-sts1 command should be limitedto the addresses that are being tested. For the example, the commands aresw-path-sts1:mb1-1 and sw-path-sts1:mb2-1.
The rtrv-state-path and sw-path-sts1 commands use slightlydifferent STS-1 ring channel designations from the cross-connectdesignations because these commands need to identify which of the twopaths around the ring is currently active. If the ring path and selectedSTS-1 channel are being received on main B-1, the active ring channeldesignation for the rtrv-state-path and sw-path-sts1 commandswill be mb1-1, where the mb1 is the path received on main B-1. If the ringpath and selected STS-1 channel are being received on main B-2, the ringchannel designation for the rtrv-state-path and the sw-path-sts1commands will be mb2-1, where the mb2 is the path received on main B-2.The DDM-2000 OC-12 allows a per path designation on the sw-path-sts1 command. This assures that only the new DS3 service beingprovisioned will be subject to protection switch hits. If this is not the firstDS3 service being added to the ring, it is strongly recommended that thepulling of circuit packs or fibers to test the protection path not be done sinceit would subject existing DS3 services to protection switch hits.

Ring Drop and Continue Cross-ConnectionProvisioning 8
All the information on "Ring Cross-Connection Provisioning" applies to "Ring Dropand Continue Cross-Connection Provisioning." Please review "Ring Cross-Connection Provisioning" as that information is not repeated here. Only the newprovisioning information is presented here. This information applies to STS-1traffic. Only the cross-connection addresses are different.
Two nodes are defined to be drop and continue nodes in a ring subnetwork andare the exit points where "two" copies of the same service are available. Bymaking two copies of the same service available at two nodes, the network isprotected from failure of a node (for example, a CO) that affects all traffic on thering. For rings that carry drop and continue services, the drop and continue nodesshould be neighbors (no intermediate nodes), and all "drop and continue" trafficmust be continued on the ring connecting the two nodes. If the two nodes are not"neighbors," special procedures are required at the intermediate node. See theTOP section of this manual (Volume II).
363-206-295Administration and Provisioning
8-26 Issue 1 December 1997
In Figure 8-2 (one half of a drop and continue DRI application), CO 1 and CO 2are drop and continue nodes. Traffic continued at CO 1 used Ring 2, which is thefiber connecting CO 1 to CO 2. Likewise, continued traffic at CO 2 used Ring 1,which is the fiber connecting CO 2 to CO 1.
When a new service is added to the ring, use the normal procedures to addservice to all nodes of a ring except to the drop and continue nodes. Before a dropand continue cross-connection can be made to a low-speed function unit, the slotsmust be equipped with 3STS1E, 3DS3, or 21-type OLIU circuit packs. Thesecircuit pack types are the interface for drop and continue applications. If OLIUs areused, the function unit slots must be provisioned for linear (1+1) applications.
NOTE:Unless you have a specific application requiring DS3 interfaces, such asvideo or DS3 clear channel, it is recommended that DRI be done withSONET interfaces. This is because incoming asynchronous DS3 failures,such as loss of signal (LOS) or alarm indication signals (AIS), at drop andcontinue nodes will not generate SONET STS AIS if drop and continuecross-connections are made on a 3DS3 circuit pack. As a result, pathprotection switching will not occur on the OC-12 ring resulting in unusablesignals at the terminating end. See "Gateway Between SONET andAsynchronous Interfaces" in Section 2, "Applications," for an example ofthis application.
The cross-connection command for drop and continue at CO 1 has twoparameters. They are cross-connection type (cct) and ring identification (ring).The cct is "dc" for drop and continue. The parameter ring defines the direction ofthe continued signal. At CO 1 the ring is "mb2," which means to continue thesignal on Ring 2 toward CO 2.
Similarly at CO 2, the other drop and continue node, the cross-connectioncommand requires the same two parameters. The cct is "dc" and the parameterring is "mb1," which means to continue the signal on Ring 1 toward CO 1.

OC-12 Ring Network Drop and Continue Cross-Connection Example 8
Figure 8-3 shows a DRI network.
1. The user wants to provision a fully protected service using drop and continuecross-connections in this dual ring topology. The service is a DS3 at RT2 (bottomnode in figure) to CO 4 (top node in figure).
2. All nodes require the same release of drop and continue ring software. The twoterminating nodes (CO 4 and RT2) require low-speed 3DS3 circuit packs in afunction unit as defined by the work order.
3. The site CO 1 has two NEs: one is part of the upper ring subnetwork and the otheris a part of the lower subnetwork. They are connected by EC-1 signals provided by3STS1E low-speed circuit packs. The figure shows these connections in functionunit C of both NEs, but any available function unit can be used.
4. Note in the figure the identification of Ring 1 (clockwise) and Ring 2(counterclockwise). This identification is a key to correct provisioning and needs tobe checked before cross-connections are made.
5. The work order will specify the low-speed channel of the DS3 service, the availablehigh-speed channel on the lower ring, and the low-speed channel assigned at thedrop and continue nodes. While it is not required by DDM-2000 that the low-speedchannel of the drop and continue nodes be the same, it is recommended tosimplify record keeping.
6. For this example, the cross-connections are:
ent-crs-sts1:c-2,mb-7 at RT2 (twoway drop)ent-crs-sts1:mb-7,mb-7 at RT3 and RT1 (pass-through)ent-crs-sts1:mb-7,c-2:cct=dc,ring=mb1 at CO 1 (lower NE)ent-crs-sts1:mb-7,c-2:cct=dc,ring=mb2 at CO 2 (lower NE).
The continued signal at CO 1 must be assigned to Ring 1 ("mb1") and thecontinued signal at CO 2 must be assigned to Ring 2 ("mb2").
7. In a similar manner, the upper ring is provisioned according to the work order. Thehigh-speed and low-speed addresses do not have to be the same as the onesused in the lower ring, but they must follow the rules for rings, which is to assign asingle high-speed channel to all nodes for this DS3 service. For this example, thecross-connections are:
ent-crs-sts1:mb-7,c-2:cct=dc,ring=mb2 at CO 1 (upper NE)ent-crs-sts1:mb-7,c-2:cct=dc,ring=mb1 at CO 2 (upper NE)ent-crs-sts1:mb-7,mb-7 at CO 3 and CO 5 (pass-through)ent-crs-sts1:c-2,mb-7 at CO 4 (two-way drop).
The continued signal at CO 1 must be assigned to Ring 2 ("mb2"), and thecontinued signal at CO 2 must be assigned to Ring 1 ("mb1").

Single Homed OC-3/OC-12 VT1.5 Path SwitchedRing (0x1) 8
Figure 8-4 shows an example of an OC-3/OC-12 VT1.5 path switched ring (0x1)single homing application. The figure is placed after the example explanation andcan be removed for reference.
The DDM-2000 OC-12 ring supports ring (0x1) OC-3/IS-3 interfaces in its functionunit slots. These interfaces must be provisioned as ring (0x1). Signals passthrough the DDM-2000 OC-12 transport ring and exit to the DDM-2000 OC-3 ring.OC-12 function unit slot fn(x)-1 is connected to OC-3 main-1 and OC-12 functionunit slot fn(x)-2 is connected to OC-3 main-2. Switching is not done on the DDM-2000 OC-12 Multiplexer on these lines, or paths on these lines; rather VT1.5 orSTS-1 level path switching is done on the DDM-2000 OC-3 Multiplexer. Thisallows DDM-2000 OC-3 nodes running ring software to interface with DDM-2000nodes of an OC-12 ring in such a way as to provide ring-on-ring architecture.Each OC-3 ring so supported occupies up to three STS-1 time slots on the OC-12ring. Each OC-12 node can provision the same STS-1 time slots as other OC-12nodes to drop to the OC-3 shelf (to share STS-1s among several OC-3 shelves) orthe OC-12 node can provision different STS-1s at different sites. When ring (0x1)is used, the OC-12 ring passes the contents of these STS-1 time slots betweenthe low-speed OC-3/IS-3 lines and OC-12 high-speed lines without terminatingthem or performing any path protection switching on them. Up to four OC-3 ringscan be supported in this fashion by an OC-12 ring to maximize the OC-12bandwidth utilization. This allows access to any and all VT1.5 signals at an OC-12site. Since the high-speed signals from the OC-3 ring(s) are sent as two copies(one clockwise, the other counterclockwise) on the OC-12 ring, the OC-12 ringcapacity is limited to the OC-12 line rate.
The OC-3/IS-3 lines between an OC-12 node and an OC-3 node connected in aring 0x1 fashion behave like the OC-3 lines between the nodes on an OC-3 ringand do not perform line level protection switching. Instead, the OC-3 shelvesperform the normal path protection switching functions.
Some points to note for this application are:
■ Ring (0x1) can be thought of as a "ring on ring" with many of thecharacteristics of a single ring.
■ Pass-through cross-connections may be required at the VT and STS level.
■ The OC-3 ring can be composed of any three STSs in the OC-12.
■ An OC-12 STS may be the first STS in one extension, the second STS inanother, and the third STS in another.
363-206-295Administration and Provisioning
Issue 1 December 1997 8-31
Example Cross-Connections 8
The OC-12 (STS level) cross-connections are:
■ At CO: mb-1:a-3
mb-1 is dropped to the third STS in the OC-3 between CO and CO-1.
■ At RT1: mb-1:a-1
mb-1 is dropped to the first STS in the OC-3 between RT1 and RT1-1.
■ At RT2: mb-1:c-2
mb-1 is dropped to the second STS in the OC-3 between RT2 and RT2-2.
■ At RT3: mb-1:b-3
mb-1 is dropped to the third STS in the OC-3 between RT3 and RT3-3.
■ At RT4: mb-1:mb-1
mb-1 is passed through RT4 at the STS level.
These cross-connections can be thought of as establishing one STS of an OC-3ring embedded in the OC-12 system. This is sometimes referred to as a "ring onring." In the example, the OC-3 nodes are CO-1, RT1-1, RT2-2, and RT3-3. TheSTS itself traverses all nine nodes. An "ordinary" STS (for example, one thatcarries a DS3 from an originating node to a terminating node) can drop at only twolocations (terminate in two-way at the source and destination), and pass-throughcross-connections are needed at the intermediate nodes. There can be multipledrop (ring 0x1) type cross-connections to optical extensions.
The VT cross-connections that follow drop or pass through individual VTs in theSTSs. This is like an ordinary OC-3 ring, except that, the same OC-12 STS can bedropped to different STSs in the various OC-3s. In an ordinary ring, the same timeslot (for example m-1-1-1) is used all the way around the ring. In a ring-on-ringapplication, the time slot identification can change in each extension. The sameVTG/VT will be used but the STS can change.
363-206-295Administration and Provisioning
8-32 Issue 1 December 1997
The OC-3 (VT level) cross-connections are:
■ At CO-1: a-1-4:m-3-2-1
The first VT in the second VTG is assigned between CO and CO-1. Thisslot will be used to transport the DS1 that will terminate on port a-1-4.
■ At RT1-1: b-2-1:m-1-2-1
The above DS1 will leave the system from port b-2-1 at RT1-1. The VTG/VT slot (-2-1) is set by the cross-connection at CO-1. Because OC-12 STSmb-1 is dropped to the first STS in this OC-3 extension (m-1), port b-2-1 iscross-connected to m-1-2-1.
■ At RT2-2: m-2-2-1:m-2-2-1
At RT2, time slot mb-1 is dropped to the second STS going to RT2-2(m-2). The VT/VTG assignment remains -2-1. A VT pass-through cross-connection is needed to enable future DS1s to be dropped at RT2-2. Ifdrops will never be needed, STS pass-through cross-connections can beused.
■ At RT3-3: m-3-2-1:m-3-2-1
The VT above must also be passed through RT3-3. As before, the VTG/VTis -2-1. The OC-12 time slot is dropped to the third STS in the OC-3 in thissegment.
With these cross-connections, DS1s originating at any of the four OC-3 nodes canbe terminated at any one of the others with VT cross-connections at those nodesonly. The STS "pipe" is in place with the OC-12 cross-connections. As was thecase with the example DS1, two VT drop cross-connections and two pass-throughcross-connections are needed.

Dual Homed OC-3/OC-12 VT1.5 Path SwitchedRing (0x1) 8
Figure 8-5 is an example of an OC-3/OC-12 VT1.5 path switched ring (0x1) dualhomed application. This application is similar to the single homed applicationexcept, for single homed 0x1 applications, both OC-12 function unit slots must beequipped while, for dual homed 0x1 applications, one OC-12 function unit slotmust be empty (Node 5 slot 2 and Node 4 slot 1 in the example).
The DDM-2000 OC-12 ring supports ring (0x1) OC-3/IS-3 interfaces in its functionunit slots. These interfaces must be provisioned as ring (0x1). Signals passthrough the DDM-2000 OC-12 transport ring and exit to the DDM-2000 OC-3 ring.OC-12 function unit slot fn(A)-1 of Node 5 is connected to OC-3 main-1 andOC-12 function unit slot fn(A)-2 of Node 4 is connected to OC-3 main-2.
Protection switching is not done on the DDM-2000 OC-12 shelf for these lines orpaths on these lines. VT1.5 or STS-1 level path switching is done on theDDM-2000 OC-3 Multiplexer shelf. In 0x1 operation, the OC-12 ring passes thecontents of the STS-1 time slots between the OC-12 high-speed line and the low-speed OC-3/IS-3 lines without terminating or performing any line or pathprotection switching on them.
Example Cross-Connections 8
The OC-12 (STS level) cross-connections are:
■ At Node 4: mb-1:a-1
■ At Node 5: mb-1:a-1
The OC-3 (VT level) cross-connection is:
■ At Node 1: b-2-1:m-1-2-1

For dual homed applications, OLIUs must be installed in the proper slots at theOC-12 nodes to support the traffic direction that is required. For example, inFigure 8-6, a 21-type OLIU must be installed in Node 6 function unit b-2 allowingDS1 traffic from Node 1 to be routed to Node 6 when the proper cross-connections are made. At the DS1 drop point of the OC-3 ring, a 21-type OLIUmust be installed in function unit b-1 of the OC-3 drop shelf.
Example Cross-Connections 8
The OC-12 (STS level) cross-connections are:
■ At Node 4: mb-1:b-1
■ At Node 5: mb-1:b-1
■ At Node 6: mb-1:b-2
The OC-3 (VT level) cross-connections are:
■ At Node 1: b-2-1:m-1-2-1
■ At Node 7: m-2-2-1:b-2-1
For more examples of OC-3/OC12 dual homing cross-connections, see the TOP(Volume II) section of this manual.

Identifiers (IDs) 8
The following IDs are used for the shelf, target, CO/RT, NSAP address, and GNE.See also the Lucent Technologies 2000 Product Family Multi-Vendor OperationsInterworking Guide, 824-102-144 and the DDM-2000 Operations SystemsEngineering Guide, 824-102-151.
■ Shelf ID: The shelf ID is a parameter with values of from 1 to 8. The shelfID provides a convenient way to log into a selected shelf in a bay using theCIT. Therefore, each shelf (OC-3 or OC-12) in a bay must be assigned aunique shelf ID. The recommended numbering is to start at the bottom ofthe bay and assign the bottom shelf with a shelf ID of 1 and work up to thetop of the bay.
■ TID: The TID is a 20-character parameter that is set through the CIT usingthe set-ne command. The TID is used in the rlgn command to identifyan NE to which a CIT remote login session is being established. The TID isalso used by OSs to identify NEs using the TL1 message-basedcommunications protocol.
After the init-sys:all command is entered, the system sets the TID toa default value of LT-DDM-2000. The TID must be unique among all NEs.The default TID may be changed using the set-ne command to a uniqueuser-assigned value recognized by the OS.
■ CO/RT: The CO/RT parameter for CO or RT identifies the system ashaving the characteristics of a CO or RT. The default is RT. The parametercontrols the operation of the miscellaneous discretes and the external fancontrol.
■ NSAP: The NSAP is a multiple part address that uniquely identifies eachNE. The NSAP is used for subnetwork DCC communications using the OSIprotocol. The NSAP is set to unique values assigned to control hardware atthe factory and does not have to be modified by the user unlesssubnetwork partitioning is necessary. Subnetwork partitioning isaccomplished by assigning NEs to different areas. An NE’s area address isone of the subfields within its NSAP. The ent-ulsdcc-l3 command isused to modify an NE’s NSAP.
■ GNE: An NE that has an active TL1/X.25 link to an OS is automatically anGNE. Subnetworks can have multiple GNEs.

Overview 9
This section defines the "maintenance philosophy" outlining the various featuresavailable to monitor and maintain the DDM-2000 OC-12 Multiplexer. Specifictrouble clearing and maintenance procedures are provided in the operation andmaintenance (TOP) section of this manual (Volume II).
Three-Tiered Operations 9
Figure 9-1 shows the three-tiered operations procedures for the DDM-2000OC-12 Multiplexer. The DDM-2000 OC-12 Multiplexer operations procedures arebuilt on three levels of system information and control, spanning operations needsfrom summary-level status to detailed reporting.
The first operations tier consists of light-emitting diodes (LEDs) and pushbuttonson the user panel and circuit pack faceplates. These allow routine tasks to beperformed without a craft interface terminal (CIT) or any test equipment. The userpanel provides system-level alarm and status information for the local terminal.The circuit pack faceplate FAULT LEDs allow fast and easy fault isolation to aparticular circuit pack. The user panel and equipment indicators are described inChapter 6, “Operation Interfaces.”
The second operations tier provides access to DDM-2000 OC-12 Multiplexeroperations from a CIT over an EIA-232-D interface. System details that cannot beobtained from the first operations tier alone can be obtained over the CITinterface. A VT-100 compatible terminal or terminal emulator software running ona personal computer (PC) can be used as a CIT. Command and prompt modes
363-206-295Maintenance Description

are available with extensive on-line help features. The CIT interface supportsoperations, administration, maintenance, and provisioning (OAM&P) activitiessuch as performance monitoring (PM), on any and all network elements (NE) inthe SONET subnetwork from a single DDM-2000.
An optional graphical user interface and provisioning (CPro-2000) tool is alsoavailable. Using CPro-2000, which runs on an MS-DOS* PC, a user can takeadvantage of the graphics to do many provisioning related activities. TheDDM-2000 CIT and CPro-2000 are described in Chapter 6, “OperationsInterfaces.”
The third operations tier consists of the remote OS interfaces. The OS interfacesinclude TL1/X.25 and an IAO LAN interface.
The DDM-2000 OC-12 Multiplexer supports a full-featured TL1/X.25 interface tomultiple OSs. The DDM-2000 OC-12 Multiplexer supports alarm surveillance andPM with OSs, such as Bellcore's Network Monitoring and Analysis (NMA) OS.
The DDM-2000 OC-12 Multiplexer supports automated service provisioning withmemory administration OSs, such as Bellcore's Operations System IntelligentNetwork Element (OPS/INE) and Lucent’s ITM SNC. The DDM-2000 OC-12Multiplexer also supports remote recovery and control functions, installationprovisioning, and security over the TL1/X.25 link.
As an alternative to DDM-2000 serving as a TL1/X.25 GNE, ITM SNC R5.0 canserve as a TL1-GNE via an IAO LAN interface. DDM-2000’s TL1/X.25 and IAOLAN interfaces are described in Chapter 6, “Operations Interfaces.”
The SLC -2000 Access System supports the same X.25 and IAO LAN interfacesand TL1 message set as the DDM-2000 OC-12 Multiplexer. The SLC-2000Access System adds digital loop carrier (DLC) specific functionality to the existingTL1 messages (for example, for DLC related alarms) and in addition supportsDLC specific TL1 commands (for example, DS0 level provisioning). See 363-208-000, SLC-2000 Access System, Applications, Planning, and Ordering Guide, formore information.

Single-Ended MaintenancePhilosophy 9
As a loop-optimized product, the DDM-2000 OC-12 Multiplexer allows operationand maintenance of all remote DDM-2000 NEs in a subnetwork from a DDM-2000in a central office. A subnetwork consists of NEs interconnected by optical linesand/or an IAO LAN with the SONET data communications channel (DCC)enabled. Similarly, a technician working at a remote site can gain access to thecentral office (CO) DDM-2000 associated with that DDM-2000 OC-12 Multiplexer,as well as with other remote DDM-2000 Multiplexers in the same subnetwork. TheDDM-2000 OC-12 Multiplexer uses the SONET DCC to provide CIT remoteaccess, remote software downloads, and OS remote access. The DDM-2000OC-12 Multiplexer uses the International Standards Organization (ISO) compliantopen systems interconnection (OSI) protocol to communicate over the DCC.
Figure 9-2 shows the single-ended operations* (SEO) capability that providesremote access to all DDM-2000 systems in a subnetwork from a singleDDM-2000 location. This minimizes technician travel because most maintenance,provisioning, and administration can be performed on all DDM-2000 Multiplexersin a subnetwork by accessing any DDM-2000 Multiplexer in the subnetwork. TheSEO capability is provided by the DDM-2000 Multiplexers regardless of thesubnetwork topology as long as DCC connectivity is available. The SEO (DCC)capability can be disabled between DDM-2000 shelves to create networkmaintenance boundaries (for example, interoffice applications) or for securityreasons.
DDM-2000 OC-12 supports Lucent Technologies 2000 Product Family OI withDDM-2000 OC-3, FiberReach, SLC-2000, and FT-2000. It also supports multi-vendor OI in subnetworks with other-vendor NEs such as Tellabs TITAN 5500.See Section 2, "Applications," and Section 8, "Administration and Provisioning,"for more information about OI.
* The terms single-ended maintenance and single-ended operations (SEO) are synonymousand have traditionally been used to refer to operations among DDM-2000 systems only.Now that SEO is supported among the 2000 Product Family NEs as well as in multi-vendorapplications, the term operations interworking (OI) is more commonly used. OI amongmulti-vendor NEs will be covered later in this chapter.

Multi-Vendor OI 9
To support multi-vendor OI, DDM-2000 OC-12 R7.0 and OC-3 R13.0 supportTarget ID Address Resolution Protocol (TARP) instead of Lucent Directory Service(LDS). DDM-2000 FiberReach R3.0 and FT-2000 OC-48 R8.0 also support TARP,thus Lucent 2000 Product Family OI compatibility is still supported but not OIcompatibility with previous releases of DDM-2000 and FT-2000. Both LDS andTARP are directory services that provide NSAP-TID translations. LDS supportsadditional Lucent-only features, but TARP is the established multi-vendor standardfor SONET NEs that support TL1 OS interfaces. DDM-2000 supports the TARPData Cache (TDC) function to reduce the frequency of TARP propagationthroughout the subnetwork and to improve performance. No DSNE is required forTARP.
DDM-2000 OC-12 R7.0 has been developed to be compatible with any other-vendor NEs that also support TARP, OSI, IAO LAN, and TL1/X.25 as specified inBellcore GR-253. In addition, DDM-2000’s TARP Manual Adjacency featureenables DDM-2000 to operate in networks that include CMISE-based NEs whichmay not support TARP propagation. DDM-2000 OC-12 R7.0 supports userprovisioning of several OSI parameters to allow users to adjust their operationssubnetwork, if necessary. For example, to support subnetwork partitioning of largesubnetworks, DDM-2000 supports user provisioning of NSAP area addresses andlevel 2 Intermediate System (IS) functionality.
DDM-2000 OC-12 R7.0’s compatibility with Tellabs TITAN * 5500 DCS R5.0,including TL1/X.25 OS access with TITAN 5500 DCS serving as the TL1-GNE forDDM-2000 TL1-RNEs, has been confirmed through cooperative joint testingbetween Lucent and Tellabs. DDM-2000’s compatibility with some other-vendorNEs has also been tested by independent third-parties such as Bellcore on behalfof the SONET Interoperability Forum (SIF).
Because DDM-2000 OC-12 R7.0 is intended to facilitate OS-based centralizedoperations, and because TL1/X.25 OS access is the key standardized multi-vendor OI application, the following Remote NE Status features are notsupported:
■ Remote office alarms
■ Remote CIT alarm reports
■ Remote user panel indications
■ TBOS
■ Parallel telemetry
* TITAN is a trademark of Tellabs, Inc.
363-206-295Maintenance Description
Issue 1 December 1997 9-7
All of the above features depend on the proprietary exchange of informationamong Lucent NEs in a subnetwork, specifically the communication of eachremote NE’s alarm status to other NEs. Although the Remote NE Status featureswere supported in previous releases of DDM-2000, such Lucent-only operationsfeatures in multi-vendor subnetworks would not include other-vendor NEs, due tothe lack of applicable standards, and thus would be incomplete.
DDM-2000 OC-12 R7.0 still supports the following Lucent proprietary OIapplications between Lucent NEs in multi-vendor subnetworks:
■ Remote Craft Interface Terminal (CIT) login
■ Remote software download and copy
■ Remote NE-to-NE automatic time/date synchronization at start-up.

Maintenance Signaling 9
The DDM-2000 OC-12 Multiplexer provides maintenance signaling compliant withthe SONET standard (TR-253). The DDM-2000 OC-12 Multiplexer inserts anddetects the following alarm indication signals (AISs), which notify downstreamequipment that a failure has been detected and alarmed by some upstreamequipment:
■ SONET line AIS
■ STS-1 path AIS
■ DS3 AIS.
The DDM-2000 OC-12 Multiplexer also inserts and detects the following signals,which notify upstream equipment of a failure detected downstream:
■ Line far-end-receive failure (FERF)
■ STS-1 path yellow.
The DDM-2000 OC-12 Multiplexer also inserts and detects STS unequippedsignals. Figure 9-3 is an example of the AIS, yellow, and FERF signals generatedin response to an unprotected incoming OC-12 line failure.
Figure 9-4 shows maintenance signals used by the DDM-2000 OC-12 Multiplexerin an STS path switched ring application. In this figure, the labels on the arrowspointing into the DDM-2000 OC-12 Multiplexer indicate the maintenance signalsand failure conditions recognized by the DDM-2000 OC-12 Multiplexer. The labelson the arrows pointing out of the DDM-2000 OC-12 Multiplexer indicate thesignals generated by the DDM-2000 OC-12 Multiplexer in response to theindicated incoming signals or failure conditions.

Fault Detection, Isolation, andReporting 9
Detection 9
The DDM-2000 OC-12 Multiplexer continuously monitors all circuit packs andincoming signals for faults. Incoming SONET signals are monitored for loss ofsignal (LOS), loss of frame (LOF), loss of pointer (LOP), and bit error ratio (BER)thresholds, and for the maintenance signals described above. Incoming DS3signals are monitored for LOS and BER thresholds. The BER thresholds for DS3are based on bipolar 3-zero substitution (B3ZS) coding violations. The DS3signals received from the fiber are monitored for AIS and out of frame (OOF)conditions, unless they are provisioned for clear channel (CC) mode. DS1 timingreferences are monitored for AIS, BER, excessive out of frame (EOOF), LOF,LOS, and out of lock (OOL) conditions.
Isolation 9
When a fault is detected, the DDM-2000 OC-12 Multiplexer uses automaticdiagnostics to isolate the fault to a particular signal or circuit pack.
Reporting 9
The system automatically and autonomously reports all alarm and statusconditions through the appropriate user panel and equipment indicators, officealarm relays, and through the TL1/X.25 interface. The system stores a record ofall fault conditions and reports them on demand through the CIT and the TL1/X.25interface. The DDM-2000 OC-12 Multiplexer also stores a history of the past 500alarm and status conditions and CIT events and reports them on demand throughthe CIT interface. Each event is real time and date stamped.
If the diagnostic determines that a circuit pack has failed, the red FAULT LED onthat circuit pack is turned on. If an incoming electrical signal from the DSX fails,the red FAULT LED on the affected circuit pack flashes on and off in one-secondintervals. A failed incoming optical signal has the same effect.
The DDM-2000 OC-12 Multiplexer provides alarm holdoff and clear delays. Thealarm holdoff delays prevent transient failures from causing unnecessarymaintenance activity. The office alarms are not activated and the OSs are notnotified until a failure lasts at least as long as the alarm holdoff delay. Alarm cleardelays prevent premature clearing of alarms. Alarm indications are not cleareduntil a fault condition has been clear for at least as long as the alarm clear delay.Incoming signal failure conditions, AIS, and FERF signals, are subject to the
363-206-295Maintenance Description
Issue 1 December 1997 9-17
provisionable holdoff delay and a fixed 15-second clear delay. Yellow signals arenot subject to holdoff or clear delays. Circuit pack failures (except control circuitpack failures) are subject to the provisionable holdoff and clear delays. Refer tothe set-attr-alm andrtrv-attr-alm commands in Section 11, "Commands and Reports."
Protection Switching 9
The DDM-2000 OC-12 Multiplexer provides equipment protection switching of alltransmission and synchronization circuit packs and uses SONET standardautomatic protection switching for the OC-3 and OC-12 lines. Installation ofprotection switching equipment is optional. Protection switching occurs inresponse to automatically detected faults in the circuit packs or OC-3 and OC-12lines as well as external commands from a technician at a local/remote CIT orTL1/X.25 message-based OS interface. The DDM-2000 OC-12 Multiplexer usesSONET protection switching priorities for all transmission protection groups. Referto the switch-line, switch-fn, switch-sync, and switch-tsi commandsin Section 11, "Commands and Reports."
Automatic Line Protection 9
The DDM-2000 OC-12 Multiplexer uses the optional SONET 1+1 unidirectionalnonrevertive automatic protection switch (APS) procedures. This means that aftera cut service fiber is repaired, a location does not switch back (revert) and selectthe service set as its active fiber/OLIU set.
Status of ACTIVE LED on OLIUs 9
Figure 9-5 illustrates examples of unidirectional and nonrevertive line protectionswitches. Note the squares at locations A and C. Each square represents thetransmit or receive section of an OLIU. Figure 9-5(a) and Figure 9-5(b) areassociated with the Service (S) OLIU and Figure 9-5(d) and Figure 9-5(e) with theProtection (P) OLIU. Four optical fibers are associated with the Service andProtection OLIUs that interconnect the OLIUs at locations A and C. The two fibersconnecting the Service OLIUs are the service fibers, and the two fibersconnecting the Protection OLIUs are the protection fibers. Fibers and OLIUsshown in bold are active and carrying service.
363-206-295Maintenance Description
9-18 Issue 1 December 1997
In Figure 9-5(a), transmitted optical signals in each direction are permanentlybridged to the service and protection fibers. The same signal is transmitted onboth fibers. Each service and protection fiber and its associated OLIU aremonitored as a set. The fiber/OLIU set selected by the receiving location is theactive set and the ACTIVE LED, which in Figure 9-5(a) is on the service OLIUcircuit packs, is lit. The fiber/OLIU set not selected is the standby set, and theACTIVE LED on its corresponding OLIU is not lighted.
Contrary to other transmission circuit packs, ACTIVE LEDs on both OLIUs may belit at the same time on the same shelf. For example, in Figure 9-5(b) the receivefiber going to location C has been cut. Location C selects the protection fiber/OLIU set as active, resulting in the lighting of ACTIVE LEDs on both the OLIUs atlocation C. Location A did not switch to its protection set but continues to remainon the service set. This example illustrates the SONET standard of unidirectionalAPS. Since each location sends APS information to the other end, both ACTIVELEDs on the OLIUs at location A are also lit.
After the cut service fiber is repaired, location C will not switch back (revert) andselect the service set as its active fiber/OLIU set. This example, Figure 9-5(c),illustrates the SONET standard of nonrevertive APS.
Figure 9-5(d) and Figure 9-5(e) illustrate a second fiber failure and the resultingchanges to the active OLIUs, thus showing that both protection sets could beactive and carrying service.
APS Initiation Criteria 9
The APS is initiated by signal fail and signal degrade conditions on the receivedoptical signal. The BER of the received optical signal is calculated from violationsin the SONET line overhead B2 parity bytes. Signal fail is declared for:
— Incoming OC-12 LOS
— OC-12 LOF
— OC-12 Line AIS
— OC-12 BER exceeding 10-3.
An OC-12 BER exceeding a provisionable 10-5 to 10-9 threshold causes the signaldegrade condition. An APS is completed within 60 milliseconds of the beginning ofa hard failure such as a fiber cut.
The DDM-2000 OC-12 Multiplexer APS is "span independent." In multispanapplications, such as hubbing, an automatic or manual protection switch on onespan does not cause a protection switch on any other span.

Equipment Protection 9
The 3DS3, 3STS1E, BCP3 TSI, and TG circuit packs are 1x1 protected and usenonrevertive switching. Green ACTIVE LEDs are provided on the faceplates ofthese circuit packs to indicate which circuit packs are active (carrying service).
Synchronization Reference Protection 9
In external timing and line-timing modes, the synchronization references are 1×1protected. If neither reference is available, the system automatically switches to"holdover" timing mode.
When the TG is provisioned for synchronization messaging, the system candetermine the quality of the line-timing references by reading the synchronizationmessages in the OC-12 transport overhead bytes. If the quality is not adequate,the TG will switch to holdover until manually switched to a good reference.
If automatic synchronization reconfiguration is enabled, the TG will automaticallyselect the highest quality reference. See "Synchronization Messaging" in Section5, "Transmission and Synchronization Interfaces," and the set-sync commandin Section 11, "Commands and Reports."
The system can be provisioned to revertive or nonrevertive timing mode switching.The default is revertive. If provisioned for revertive mode switching, the systemautomatically switches from holdover mode to the provisioned timing mode(external timing or line-timing) when an unprotected timing reference failureclears. If provisioned for nonrevertive mode switching, the system must bemanually switched from holdover mode to the provisioned timing mode (externaltiming or line-timing) when an unprotected timing reference failure clears. Refer tothe rtrv-sync, set-sync, and switch-sync commands in Section 11,"Commands and Reports."

Path Protection Switching (Path Switched Rings) 9
The path switched ring application is based on the Bellcore TR-TSY-000496/GR-1400 path protection switching scheme.
The path protection switched ring has two single-fiber, counter-rotating rings asshown in Figure 9-6. This architecture has distinct advantages over a lineararchitecture. Each node on the ring terminates four fibers: a transmit and receivefiber in each direction. Eight fibers are needed to connect the same NE in anonterminal position of a linear add/drop 1+1 protected arrangement: two transmitand two receive in each direction, without providing the same level of protectionthat the ring provides. The architecture of the ring is designed to protect againstany single point of failure, including a node failure, single fiber cut, or dual fibercut. Node failure or dual fiber failure in a linear network affects traffic to alldownstream nodes. A node failure in a ring only affects traffic dropped at the failednode.
The DDM-2000 OC-12 ring provides STS-1 path protection switching to supportDS3, EC-1, and OC-3/IS-3 interfaces.
The signal that enters the ring is protected on a SONET path basis as switching isperformed independently for each path. Because of the ring's unidirectionaloperation, time slots must be reserved all the way around the ring for all ringtraffic, limiting the capacity of the ring to the OC-N line rate.

Path Protection Scheme 9
Path protection rings feed a SONET payload (STS) from the ring entry point,simultaneously in both rotations of the ring, to the signal's ring exit point as shownby traffic AC and CA in Figure 9-7(a). This duplication of the signal that enters thering is called a "head-end bridge." The node that terminates the signal from thering monitors both ring rotations and is responsible for selecting the signal thathas the highest quality based on LOS/LOF, path AIS, LOP, path unequipped andpath BER performance. This function at the ring exit point is called a "tail-endswitch." Path switching is nonrevertive. On pass-through paths, detected hardfailures (LOS, LOF, LOP, line AIS, and STS-1 path AIS) result in path AIS insertionin the outgoing signals. This allows the terminating node to detect path failure andswitch to protection.
Under normal conditions, both incoming SONET path signals to the switchselection point are of high quality, and the signal can be selected from either ring.A failure or a transmission degradation on one of the rings requires that the otherring path be selected, and requirements specify that this path selection mustoccur within 60 milliseconds after a hard failure condition. Figure 9-7(b) showshow traffic is switched when a dual-fiber cut occurs. Nonrevertive switching isprovided to minimize the impact on critical customer services by giving the serviceprovider control when, and if, the critical service should revert to a particular ring.A manual path protection switching command allows switching back to the originalpath for ease of ring maintenance. Refer to the switch-path commands inSection 11, "Commands and Reports."

Dual Ring Interworking (DRI) Path ProtectionScheme 9
Interconnected rings or DRI is a topology that connects two rings together at twogeographically separate nodes to provide an alternate route if a catastrophicfailure occurs at one of the interconnecting nodes. See Section 2, "Applications,"for more information on DRI. Figure 9-8 shows DRI path protection switching.Note that the upper ring could be an FT-2000 OC-48 Lightwave Systembidirectional line switched ring. In the receive direction, a DRI node that passes asignal between rings performs two steps:
1. VT1.5 and/or STS-1 signals to be passed between rings are "dropped andcontinued." This means the signal is dropped at that node to the FunctionUnit and simultaneously copied into the OC-3/OC-12 signal in the outgoingdirection of the same ring rotation.
2. The VT1.5 and/or STS-1 signal that was dropped in Step 1 and thecorresponding VT1.5 and/or STS-1 signal incoming from the other ringdirection are compared, and the signal with the highest quality is selectedas in single ring topologies.
In the transmit direction, a DRI node feeds VT1.5 or STS-1 signals in the directionopposite to the "continue" portion of the drop and continue signal (Step 1previously) to only one rotation of the ring as shown in Figure 9-8.
This routing is to only one rotation or "disabled bridge" as distinguished from howan ordinary path switched ring bridges incoming low-speed traffic onto bothrotations.
The drop and continue disabled bridge routing necessary for DRI is establishedwith a cross-connection command.

OC-3/OC-12 Path Switched Ring (0x1) 9
A DDM-2000 OC-3 ring shelf can function in a ring-on-ring application using the0x1 interface capability of the OC-12 or FT-2000 OC-48 Lightwave System ring.The OC-3 shelf functions in the normal path switched ring mode. VT/STS pathprotection switching is done on the OC-3 shelf.
In single homing, the OC-3 ring shelf interconnects through its main-1/main-2 ringinterface either directly or through another OC-3 ring shelf to the low-speed OC-30x1 interface on a single OC-12 or FT-2000 OC-48 Lightwave System shelf.
In dual homing, the OC-3 ring shelf interconnects directly or through anotherOC-3 ring shelf with the OC-3 interfaces on two separate and normally non-colocated OC-12 or FT-2000 OC-48 Lightwave System shelves.
Status of ACTIVE LED on Rings 9
In ring applications, ACTIVE LEDs on each main OLIU are always lit because it isnot known if a signal on that OLIU is currently being selected by a far-end NE.
Loopbacks 9
The DDM-2000 OC-12 Multiplexer allows technicians to do loopbacks on all low-speed DS3 and EC-1 interfaces. Low-speed DS3 and EC-1 electronic loopbacks,directed toward the high-speed OC-12, are individually controllable from the CIT.Facility loopbacks can also be set up towards the DSX on all low-speed DS3 andEC-1 interfaces. Active electronic loopbacks are noted by the user panel'sabnormal (ABN) indicator and in the alarm and status report. See theopr-lpbk-ds3, opr-lpbk-ec1, rls-lpbk-ds3, and rls-lpbk-ec1commands in Section 11, "Commands and Reports."
Front access to the OLIU optical connectors allows an easy manual OC-3 andOC-12 optical loopback. This loopback is performed by connecting a fiber jumperfrom the OLIU output to its input. On the 21-type OLIUs, no optical attenuator isrequired for this loopback. However, the optical output power switch on the 21G/21G-U OLIU circuit pack must be set for low output power to prevent receiveroverload when an optical loopback is set up. On the 23G/23G-U OLIU, an externaloptical attenuator is required to prevent receiver overload during manual opticalloopback.

Tests 9
Transmission Tests 9
Technicians can use DDM-2000 OC-12 Multiplexer internal testing capabilities forinstallation and manual troubleshooting. DS3 test signal generators and detectorsare integrated in the system, eliminating the need for external test equipment todo DS3 transmission testing.
The DDM-2000 OC-12 Multiplexer lets technicians test specific signals andsystem components. For example, technicians can manually enable theintegrated test signal generators and detectors for a DS3 low-speed interface.These signal tests can be run selectively in the multiplex or demultiplex direction.Refer to the test-trmsn-t3 command in Section 11, "Commands andReports."
Operations Interface Tests 9
The DDM-2000 OC-12 Multiplexer also provides tests for LED indicators, officealarms, and the system controller. Refer to the test-led, test-alm, andtest-sysctl commands in Section 11, "Commands and Reports."
Performance Monitoring (PM) 9
The DDM-2000 OC-12 Multiplexer uses PM to support proactive maintenanceand tariff verification of the network. Proactive maintenance refers to the processof detecting degrading conditions not severe enough to initiate protectionswitching or alarming but indicative of an impending hard or soft failure. Hard andsoft failures result in reactive maintenance.
Proactive maintenance consists of monitoring performance parametersassociated with the SONET sections, lines, and paths within the SONET network.Table 9-4 lists the SONET and DS3 performance parameters monitored by theDDM-2000 OC-12 Multiplexer. These parameters are thresholded to indicatedegraded performance. When a PM threshold is crossed, it is reported to the OSconnected to an TL1/X.25 link. All threshold crossings associated with a particularpath can be correlated, and the likely source of the degradation can be identified.
363-206-295Maintenance Description
9-28 Issue 1 December 1997
Tariff verification refers to the process of collecting PM data on end-to-end pathservices (for example, DS1 and DS3). This data can be used to verify whether ornot a customer is receiving the quality of service requested. Refer to Appendix A,"A SONET Overview," for more information on SONET PM.
Figure 9-9 shows DS1/DS3 line and path and DS3 path PM.
Figure 9-9. DS1/DS3 Line and Path and DS3 Path Performance Monitoring
The following are definitions and explanations for the terms used in the figure:
■ Line — A line is a physical transport vehicle that provides the means ofmoving digital information between two points in a network. The line ischaracterized by a metallic transmission medium and its specific codingtype. A line is bounded by its two end points, known as line terminations. Aline termination is the point where the electrical, bipolar line signal isgenerated and transmitted, or received and decoded.
— DS1 (DDM-2000 OC-3 Only) — DS1 line for AMI or B8ZS coding ismonitored and the errored second (ES-L) data is displayed for theincoming signal from the DSX-1.
— DS3 — DS3 line for B3ZS coding is monitored and the data isdisplayed in CV-L, ES-L, and SES-L registers for the incoming signalfrom the DSX-3.
■ Path — A path is a framed digital stream between two points in a networkand represents digital signal transport at a specified rate, independent ofthe equipment and media providing the physical means of transporting thesignal. A path is defined by its two end points, called path terminations,where its frame structure is generated and decoded. A path may be carriedwholly within one transport segment (line), or it may span a sequentialarrangement of two or more transport segments.

— DS1 (DDM-2000 OC-3 Only) — DS1 near-end path is monitored forSF framing and both near-end and far-end paths are monitored forESF framing. The data is displayed in ES-P, SES-P, and UAS-Pcategories. CV-P is also displayed.
— DS3 — DS3 path incoming from the fiber (high-speed side) ismonitored for both P-bits and F&M bits and the data is displayed inCV-P, ES-P, SES-P, and UAS-P registers. In addition, severelyerrored frame seconds (SEFS) are also monitored and displayed.
DS3 path incoming from the DSX-3 (low-speed side) is alsomonitored, in addition to monitoring the path from the fiber, for bothP-bits and F&M bits. The same registers are also displayed for thedata from the DSX-3. DS3 path from both the fiber and the DSX-3are monitored for C-Bits and are displayed in the same registers asabove. The far-end data (FEBE bits) is monitored and displayed aswell.
DS3 Performance Monitoring (PM) 9
DS3 Path PM 9
DDM-2000 OC-12 provides three DS3 path PM options using the BBG11B DS3circuit pack: P-bit (parity bit), adjusted F&M bit, and C-bit. The options areselected using a command that also sets the PM mode to "on" (default) or "off",which enables or disables the monitoring and reporting of DS3 path PM data (seeTable 9-4).
P-Bit 9
When provisioned for P-bit, the system calculates and provides counts of DS3P-bit coding violations (CV), errored seconds (ES), severely errored seconds(SES), and unavailable seconds (UAS) incoming from the fiber and DSX. Quarter-hour and current day registers are provided with provisionable threshold crossingalerts (TCAs) on a per shelf basis. SEFS are also monitored.
Because P-bits can be corrected at nodes provisioned for violation monitor andremoval (VMR) along a DS3 path, the DS3 P-bit PM data may not provide acomplete report of the end-to-end DS3 path errors.
Adjusted F&M Bit 9
Adjusted F&M bit PM provides an alternative method for determining andaccumulating DS3 path performance data based on an error estimation techniqueusing errors on the F&M framing bits to approximate the actual error counts in theDS3 path payload. F&M bits are not corrected at nodes provisioned for VMRalong a DS3 path. When provisioned for adjusted F&M bit, the system calculates
363-206-295Maintenance Description
9-30 Issue 1 December 1997
and provides estimated counts of DS3 adjusted F&M bit CV, ES, SES, and UASincoming from the fiber and DSX. Quarter-hour and current day registers areprovided with provisionable TCAs on a per-shelf basis. SEFS are also monitored.
C-Bit 9
When the DS3 path PM C-bit option is selected, both near-end and far-end (far-end block errors) PM data are monitored and displayed.
The system provides counts of DS3 C-bit parity CV-P, ES-P, SES-P, and UAS-Pincoming from both the DSX-3 and the fiber. The type of PM is provisioned perDS3 service by a CIT command.
For C-bit PM, the DS3 service can be provisioned in VM or VMR modes. In VMRmode, the C-bit errors are not corrected as in the P-bit option.
Quarter-hour and day registers are provided with provisionable TCAs. The TCAsare provisionable on a per-shelf basis. SEFS counts are also provided.
DS3 Line Performance Monitoring 9
DS3 line parameters include CVL, ESL, and SESL. DS3 line PM providesprovisionable bit error ratios (TCAs) for all DS3 line parameters. For CVLparameters, bit errors can also be provisioned in ratios such as 10-7, 10-8, and10-9.
DS3 Performance Monitoring Parameters 9
Table 9-4 lists the performance parameters monitored by the DDM-2000 OC-12Multiplexer. The collection of performance parameters depends directly on slotstate transitions, port states, and cross-connections.

Line protection switch counts do not apply to EC-1 interfaces.
STS-1 Path Parameters 9
Performance Monitoring Enabling 9
Collection of STS-1 path parameters is initiated only when a slot is equipped witha 3DS3 circuit pack. Parameters continue to be available in reports and generateappropriate TCAs until the 3DS3 circuit pack is removed and the updatecommand or the UPD/INIT button is pressed. Path parameters are monitored onlyon active circuit packs.
STS-1 Path Coding Violations (B3 Parity) 9
The performance of the STS-1 path is monitored by writing the "B3" byte in theSTS-1 path overhead when the path is originated and checking the "B3" byte forerrors when the path is terminated. The B3 coding violation counter isincremented for each error detected. Up to eight errors per STS-1 frame can bedetected in each STS-1 synchronous payload envelope (SPE). B3 codingviolations are counted and thresholded separately for each STS-1 pathterminated by the system.

CV-P Coding Violations 9
CV-P coding violations are a count of the number of P-bit, adjusted F&M bit, ornear-end and far-end C-bit parity errors in the DS3 signal received from the fiberand the DSX-3. To detect degradation of the signal, these errors are counted andthresholded independently for all DS3 interfaces provisioned in VM or VMR mode.By provisioning all NEs in the DS3 path to the VM mode, coding violations can beused as a DS3 path performance parameter when the P-bit option is selected.When the F&M-bit or C-bit option is selected, NEs could be provisioned in VMR orVM mode (see Table 9-6).
Severely Errored Frame Seconds (SEFS) 9
SESF are a count of the number of seconds during which an OOF or AIScondition exists for a DS3 signal received from the fiber or the DSX-3, or during anunprotected DS3 circuit pack failure. SEFSs are counted and thresholdedindependently for all DS3 interfaces provisioned in VM or VMR mode.

Electrical Interfaces 10
The DDM-2000 OC-12 Multiplexer supports DS3 and EC-1 electrical low-speedinterfaces.
DS3 Low-Speed (BBG11/11B 3DS3) 10
■ Electrical Specification
The low-speed DS3 interface transmits/receives a standard electrical DS3signal as specified in ANSI T1.102-1993, Section 5 (44.736 Mb/s rate,DSX-3 interconnect specification, bipolar 3-zero substitution [B3ZS]encoding). However, the signal does not have to contain a standard DS3frame.
Line build-out is provisionable as follows:
— 734A/D: Up to 450 ft.
— Mini-Coax (KS-19224, L2): 0 to 150 ft.
— 735A: Up to 250 ft.
■ Format Specification
The DS3 low-speed interface provides clear channel (CC) transport of anyDSX-3 compatible signal (M13 mode, framed CC, unframed CC). Thus,there are no format requirements on this interface.
■ Alarm Thresholding
The following parameters are monitored at the DS3 interface to the DSX-3:
— Loss of signal (LOS)
— Line coding violations (CV-L).
The alarm level for each of the monitored parameters can be provisioned toCR, MJ, MN or status. B3ZS coding violation failure threshold is usersettable to 10-3 or 10-6 BER.
■ Performance Monitoring (PM) (see Table 10-14)
— DS3 Parity Errors (P-bits)
DDM-2000 OC-12 Multiplexers provide for DS3 P-bit violationmonitoring and removal (VMR) based on the provisioning mode ofthe DS3 low-speed interface. Table 10-2 defines P-bit monitoringand correction actions in each of the DS3 modes.
— Severely Errored Frame Seconds (SEFS)
DDM-2000 OC-12 Multiplexers count the number of seconds duringwhich an out-of-frame (OOF) condition exists for DS3 signalsreceived from the fiber.
363-206-295Technical Specifications
Issue 1 December 1997 10-3
Table 10-2. DS3 Performance Monitoring (PM) Mode
If provisioned in the VMR or VM modes (Table 10-2), DS3 P-bit violations andSEFS are counted and the count is thresholded to flag detected performancedegradation of the DS3 signal incoming from the fiber.
■ Enhanced DS3 Performance Monitoring (see Table 10-14)
— CV-P Coding Violations
These errors are counted and thresholded independently for all DS3interfaces provisioned in VM or VMR mode. When the F&M bit orC-bit option is selected, network elements (NE) could beprovisioned in VMR or VM mode. See Table 10-3.

— Severely Errored Seconds (SES-P)
A SES-P is a second in which 44 or more DS3 P-bit, adjusted F&Mbit, or C-bit coding violations are detected. SES-P are not countedduring UAS-P.SES-P are counted and thresholded independently for each DS3path terminated by the system.
— Unavailable Seconds (UAS-P)
An “unavailable second” is a second during which the DS3 path isunavailable. A DS3 path is considered unavailable from thebeginning of X consecutive SES-P until the beginning of Yconsecutive seconds, none of which is severely errored. X is equalto 10 seconds or, in the case of a failure, the DS3 signal failure. A Yis equal to 10 seconds of no SES-P or DS3 signal failures. If thereis an unprotected DS3 circuit pack failure, UAS-P are counted fromwithin 1 second of circuit pack failure to within 1 second of circuitpack recovery. UAS-P are counted and thresholded independentlyfor each DS3 path terminated by the system. This applies to P-bit,adjusted F&M bit, and C-bit options.
— Severely Errored Frame Seconds (SEFS)
SEFS are a count of the number of seconds during which an OOFor AIS condition exists for a DS3 signal received from the fiber, orthe DSX-3, or during an unprotected DS3 circuit pack failure. SEFSare counted and thresholded independently for all DS3 interfacesprovisioned in VM or VMR mode.
— Line Coding Violations (CV-L)
This parameter is a count of B3ZS bipolar violations (BPV)occurring over the accumulation period. BPVs that are part of thezero substitution code are excluded.
— Errored Seconds LIne (ES-L)
This parameter is a count of seconds containing one or more BPVs,or one or more LOS (from the DSX-3) defects.
— Severely Errored Seconds LIne (SES-L)
This parameter is a count of seconds during which BPVs exceed44, or one or more LOS defects occur.

Optical Interfaces 10
The DDM-2000 OC-12 Multiplexer supports OC-12 long-reach applications at1310 nm using the 23G/23G-U OLIU and at 1550 nm applications using the 23H/23H-U OLIU. The DDM-2000 OC-12 Multiplexer also supports OC-3 opticalextensions using the 21G/21G-U/21G2-U and 21D/21D-U (IS-3) OLIUs. The 21G/21G-U/21G2-U OLIU is fully SONET compliant. The 21D/21D-U OLIU is a low-cost IS-3 low-speed interface used primarily to interconnect the DDM-2000 OC-3Multiplexer to the DDM-2000 OC-12 Multiplexer at the same site. The nominalOC-3 and IS-3 line rates are 155.520 Mb/s.
Lightguide Jumpers 10
The DDM-2000 OC-3 and OC-12 Multiplexers provide Lucent Technologies’universal optical connector on all OLIUs. The universal optical connectors arereceptacles on the faceplate of the OLIUs that allow a single OLIU to supporteither ST®, FC-PC, or SC connectors as needed. Both 0 dB and attenuatingbuildouts are supported.
To prevent potential degradations, the DDM-2000 OC-12 lightguide interfacerequires single-mode jumpers for connecting to and from the outside plant LGX®
panel and the DDM-2000 OC-12 for all OLIUs, except the 21D/21D-U OLIU.
The 21D/21D-U OLIU, used for intershelf OC-3/OC-12 interconnection, must usemultimode jumpers on the transmit and receive sides.
Lightguide jumpers can be ordered from Lucent. See the "OC-12 Ordering —Miscellaneous Equipment and Tools" section of 363-206-200 DDM-2000 OC-3and OC-12 Multiplexers Applications, Planning, and Ordering Guide, for orderinginformation.

‡ The minimum system gain for the DDM-2000 already takes into account aging, temperature, andmanufacturing tolerances as these figures are built into the minimum transmitter power. TheDDM-2000 system gain can, thus, not be directly compared with the DDM-1000 system gain becausethe DDM-1000 system gain does not include all of these effects. A similar penalty, called eye margin,is subtracted from the DDM-1000 loss budget after the value of system gain is determined.
§ Optical path penalty includes effects of dispersion, reflection and jitter that occur on the optical path.
¶ One connector (0.75 dB) on each end is assumed to connect station cable to outside plant.
∗∗ Unallocated margin, or safety margin, is typically specified from 0 dB to 3 dB.
†† If the loss budget is less than 6.0 dB, use low power. Includes a 1.5 dB safety margin.
‡‡ Budget available for both station and transmission cable and splices.
§§ Attenuation and dispersion can be the limiting factors in span length. For OC-3 single-mode fibersystems, dispersion is not a factor and all applications are attenuation limited. For OC-12 systems,the maximum distance could be either attenuation limited or dispersion limited. The limits must becalculated based on both factors and the lesser of the two defines the actual maximum span length.A rough rule of thumb for attenuation-limited systems is 0.45 dB/km. This estimate includes typicalcable loss (0.4 dB/km) and splice loss (0.2 dB per splice, 11 total splices) associated with single-modefiber.
Maximum span length can be calculated more precisely based on particular fiber and splicecharacteristics and local engineering rules.
¶¶ Full width at half maximum (FWHM) spectral width.

Notes:
1. Maximum 21G/21G-U/21G2-U MM Link Budget (dB) for multimodeoperation is 22.0 dB for high power and 15.6 dB for low power.
2. When two numbers are given, the number before the slash is thespecification for operating under controlled environmental conditions. Thenumber following the slash is the specification for uncontrolledenvironmental conditions. If only one number is given, it applies to bothcontrolled and uncontrolled environmental conditions.
Multimode fiber operation on the DDM-2000 OC-3 Multiplexer requires a minimumexit bandwidth of 120 MHz to ensure that dispersion loss is kept below acceptablelevels. If the fiber is already installed and the exit bandwidth is measured to be120 MHz or greater, then the maximum link budget values (22 dB, 15.6 dB, and 12dB, respectively) can be used to determine if the loss budget is sufficient for thatfiber.
The system is dispersion limited for all the fiber bandwidths listed in this table.
If planning a new fiber installation, the values at the end of the table, given for anumber of commercially available fiber bandwidth-distance products, can beused. Fiber distances are calculated using the 120 MHz exit bandwidth limit,however, actual exit bandwidths may be higher for these distances due to theexistence of splices. This may permit longer span lengths to be achieved, for thegiven fiber bandwidths, than those specified in the table. In this case, however, thespan length can only be increased to the point where the system is loss-limited asspecified by the maximum multimode link budget given in the table (1 dB/km cableis assumed).

¶ Optical path penalty includes effects of dispersion, reflection and jitter that occur on theoptical path. The 23G/23G-U has 5.0 dB of total margin. Optical path penalty is normally1.0 dB. This allows for a maximum dispersion of 92 psec/nm in the 1310 nm wavelengthrange. To allow for span lengths greater than 40 km, 2.0 dB is allocated for optical pathpenalty. This allows a maximum dispersion of 120 ps/nm. 1.0 dB is allocated for theoptical path penalty for the 23H/23H-U for operation in the 1550 nm wavelength range.This allows a maximum dispersion of 1800 ps/nm.
** One connector (0.75 dB) on each end is assumed to connect station cable to outsideplant.
†† Unallocated margin, or safety margin, is typically specified from 0 dB to 3 dB.
‡‡ The 23G/23G-U requires an external lightguide buildout as part of the connectorassembly for loopbacks and for loss budgets less than 10 dB. The 23H/23H-U requiresan external lightguide buildout as part of the connector assembly for loopbacks and forloss budgets less than 19 (23H) or 10 (23H-U) dB.
§§ Budget available for both station and transmission cable and splices.
¶¶ Attenuation and dispersion can be the limiting factors in span length. For OC-12systems, the maximum distance could be either attenuation limited or dispersion limited.The limits must be calculated based on both factors and the lesser of the two defines theactual maximum span length. A rough rule of thumb for attenuation-limited systemsoperating in the 1310 nm wavelength range is 0.45 dB/km. This estimate includes typicalcable loss (0.4 dB/km) and splice loss (0.2 dB per splice, 11 total splices) associatedwith single-mode fiber in the 1310 nm range. A rough rule of thumb for systemsoperating in the 1550 nm wavelength range on modern nondispersion shifted fiber is0.25 dB/Km.
Allowing 2.0 dB for the optical path penalty implies 120 ps/nm total dispersion in the1310 nm wavelength range. Typical maximum slope for single-mode fiber in thiswavelength is 0.092 ps/nm squared per km. Typical nondispersion shifted fiber has azero dispersion wavelength between 1300 and 1320 nm. Given these assumptions, themaximum span length for the 23G/23G-U is 51km.
For OC-12 systems operating in the 1550 nm wavelength range, the maximum distanceis dispersion limited. Allowing 1 dB for the optical path penalty implies 1800 ps/nm totaldispersion. Typical modern nondispersion shifted fiber has 18 ps/(nm•km) dispersion inthe 1550 nm wavelength range. Given these assumptions, the maximum span length forthe 23H/23H-U is 100 km.
Maximum span length can be calculated more precisely based on particular fiber andsplice characteristics and local engineering rules.

OC-3 Optical Interface Mixing 10
Mixing different OC-3 rate OLIUs at opposite ends of an optical link is oftennecessary for technical reasons or for convenience. The following information willaid in planning and engineering optical links having different types of OC-3 rateOLIUs at each end of the fiber. Table 10-9 details the minimum link budgetnecessary for each pairing of OC-3 rate OLIUs.
To use Table 10-9, locate the number at the intersection of the transmitter/receiverpair of interest. This number is the minimum attenuation necessary for properoperation of that transmitter/receiver pair. The link must have at least this muchattenuation either from fiber loss, splice loss, connector loss, external attenuators,or a combination of these, or the receiver will be overdriven and the link will notoperate properly.
Note that the minimum link budget is not always symmetrical. A transmitter/receiver pair may have one minimum link budget in one direction and another inthe opposite direction. For example, a 21G/21G-U (low power) OLIU transmittingto a 21D/21D-U (controlled environment) OLIU has a minimum link budget of 6.5dB. In the opposite direction, though, a 21D/21D-U (controlled environment) OLIUtransmitting to a 21G/21G-U (low power) OLIU has a minimum link budget of 0.0dB. Be careful of this asymmetry when planning and engineering a link havingmixed OLIUs.

10-18 Issue 1 December 1997
NOTE:When using universal optical buildout attenuators for OLIUs equipped withUniversal Optical Connectors (for example, 22G-U and 22D-U), the buildoutmust have the same type fiber on both sides, that is, single-mode to single-mode or multimode to multimode. The buildout must also match the modeof the fiber. Therefore, when a single-mode jumper is used, the buildoutwould be on the transmit side (OUT) of the OLIU and when a multimodejumper is used, the buildout would be on the receive side (IN) of the OLIU.When using in-line attenuators for non-U OLIUs, place the attenuator in thebay frame PANDUIT. Make sure that the mode type of the attenuatormatches the mode of the fiber to ensure proper attenuation.
Table 10-10 details the maximum link budgets for each pairing of OC-3 rate OLIUswhen operating on single-mode (SM) fiber. These numbers give the maximumattenuation acceptable for proper operation of each transmitter/receiver pair. Thelink must have no more than this much attenuation either from fiber loss, spliceloss, connector loss, external attenuators or a combination of these or the link willnot operate properly. The maximum link budgets for SM fiber were calculatedusing the following margins:

The link must have no morethan this much attenuation either from fiber loss, splice loss, connector loss, externalattenuators or a combination of these or the link will not operate properly. The maximum linkbudgets for MM fiber were calculated using the following margins. The first column ofmargins applies to any link where there is at least one OC-3 OLIU (21G/21G-U, 22F or22G-U/22G2-U).

Protection Switching 10
Ring Networks 10
Path protection rings feed a SONET payload (STS or virtual tributary [VT]) fromthe ring entry point, simultaneously in both rotations of the ring, to the signal's ringexit point. The node that terminates the signal from the ring monitors both ringrotations and is responsible for selecting the signal that has the highest qualitybased on LOS, path AIS, and path BER performance. On pass-through paths, alldetected hard failures (LOS, LOF, LOP, line AIS, STS path AIS, or STSunequipped) result in STS AIS insertion in the outgoing signals. This allows theterminating node to be aware of the failure and to switch to protection. Protectionswitching is completed within 50 milliseconds of failure detection.
Under normal conditions, both incoming SONET path signals to the switchselection point are of high quality, and the signal can be selected from either ring.A failure or a transmission degradation on one of the rings requires that the otherring path be selected. Nonrevertive switching minimizes the impact on criticalcustomer services by giving the service provider control when, and if, the criticalservice should revert to a particular ring. A manual path protection switchingcommand allows switching back to the original path for ease of ring maintenance.

Operations Interfaces (OI) 10
This section presents the operations interfaces that are required to supporttechnician access to the system and allow alarms and status informationgenerated by the system to be reported. The local operations interfaces includethe CIT interface, the user panel, and the equipment indicators. DDM-2000 OC-12Multiplexers support office alarms, user-definable miscellaneous discretes, andTL1/X.25.
Craft Interface Terminal (CIT) 10
The system provides two EIA-232-D compatible CIT interfaces—a front accessinterface, configured as a DCE, and a rear access CIT interface, configured as aDTE—to allow a permanent modem connection without requiring a null modem. Anull modem is required to connect an ASCII terminal to the DTE interface or amodem to the DCE interface. The CIT interfaces provide data rates of 300, 1200,2400, 4800, 9600, and 19200 baud.
Both CIT interfaces operate full duplex using 1 start bit, 8 data bits, and 1 stop bit.Table 10-15 describes the pins supported on the CIT interfaces:
Table 10-15. CIT Interface Pin Connection
A CIT is recommended for installation, maintenance, and administrative activities.A PC is required for software download and to run CPro-2000 software. TheDDM-2000 OC-12 Multiplexer CIT port (mounted on the user panel) is a standardEIA-232-D (supersedes RS-232C specification) interface configured as DCE fordirect connection to a CIT. The CIT port will support rates of 300, 1200, 2400,4800, 9600, and 19200 baud and should be compatible with most ANSI 3.64

TL1/X.25 Interface 10
The DDM-2000 Multiplexer supports a TL1/X.25 interface for communicationbetween local and remote DDM-2000 (and FT-2000) NEs and alarm surveillanceand provisioning operations systems (OS) such as Bellcore's NMA and OPS/INEOSs. The DDM-2000 OC-12 Multiplexer TL1/X.25 interface is based on BellcoreTR-TSY-000833, Issue 5. The DDM-2000 supports up to nine X.25 permanentvirtual circuits (PVCs) and up to nine switched virtual circuits (SVCs) assigned bydefault as shown in Table 10-16. The user may assign a maximum of nine VCsusing any combination of PVCs and SVCs.
Table 10-16. TL1/X.25 Interface — VC Assignments
All VCs support command/response messages. The autonomous maintenancemessages are all TL1 autonomous messages except REPT DBCHG.
If the default assignments in Table 10-16 do not meet the user’s OS needs,DDM-2000 allows users to specify the routing of TL1 autonomous message typesto VCs. This is done in two steps:
1. Each TL1 autonomous message type (e.g., REPT ALM, REPT DBCHG,REPT PM, etc.) can be mapped to any OS type (using theent-tl1msgmap command at every DDM-2000 in the subnetwork). TheOS types are tl1Maintenance, tl1MemoryAdministration, tl1test,tl1PeerComm, tl1Other1 and tl1Other2.
2. Each OS type can be mapped to any of the VCs (using the ent-osacmapcommand at the DDM-2000 TL1 GNE). The combination of Step #1(mapping TL1 autonomous message types to OS types) and Step #2(mapping OS types to VCs) accomplishes the desired mapping of TL1autonomous message types to VCs.

DDM-2000 OC-12 Reliability 10
Summary 10
This section describes the Bellcore reliability requirements that apply to theDDM-2000 OC-12 Multiplexer and the calculations used to predict how theDDM-2000 OC-12 Multiplexer meets those standards.
The DDM-2000 OC-12 Multiplexer meets all the applicable Bellcore reliabilityrequirements that cover transmission availability, OS availability, silent failures,optical module maintenance, and infant mortality. Table 10-21 summarizes thereliability predictions and requirements. The applicable Bellcore requirements andobjective were clarified through interactions with Bellcore during their audit of theDDM-2000 OC-12 Multiplexer. The basis for these requirements comes fromTA-TSY-000418, "Generic Reliability Assurance Requirements for Fiber OpticTransport Systems." The method and assumptions used to calculate theDDM-2000 OC-12 Multiplexer reliability predictions are described in the followingsections. Each section is devoted to one of the reliability parameters which mustmeet a Bellcore requirement or objective.
Transmission Availability 10
Bellcore requirements state that the probability of a hardware-caused outage on atwo-way channel within a SONET multiplexer should be less than 1.75 minutesper year in a CO environment* and 5.25 minutes per year in a RT environment.†
Bellcore objectives for outages are 0.25 minutes per year for the CO‡ and 0.75minutes per year for RT environments.§
The outage requirements and objectives apply to any part of the product neededto process an incoming high-speed or low-speed signal (DS3 to OC-12 or OC-12to DS3). An outage is defined, for this and all other outage requirements, as any1-second interval with a bit error rate of 10-3 or worse.¶ The predicted hardwareoutages for various configurations of the DDM-2000 OC-12 system are given inTable 10-21.
A Markov model was used to calculate the predicted system outage. The modelassumes a mean time to repair of 2 hours for the CO environment and 4 hours forthe RT environment. Individual circuit pack failure rates used in the model werecalculated using the method described in TR-TSY-000332, Issue 4, "ReliabilityPrediction Procedure for Electronic Equipment (RPP)."

The Bellcore objective states that the OS outage should be less than 28 minutesper year (50 percent hardware, 50 percent software).* Therefore, the objectiveapplies to the TL1/X.25 interface. This objective applies to circuitry needed tomaintain communication from the DDM-2000 OC-12 Multiplexer to the centraloffice's OS. Since the OS interface is used in the central office, the reliabilitymodel assumes the mean time to repair is 2 hours and the environmental factor is1.0. Table 10-21 lists the predicted outages for the TL1/X.25 interface.
Optical Module Maintenance Objective 10
According to Bellcore, the objective for mean time between failure (MTBF) of aone-way regenerator is a minimum of 4 years. A regenerator is defined as anycircuit packs that perform the electrical-to-optical and optical-to-electricalconversion. The failure rate of the 23G/23G-U OLIU is 11400 FITS according tothe RPP method. This translates to a MTBF of 10 years, which meets theobjective.
Infant Mortality 10
Bellcore requires that the number of circuit pack failures in the first year ofoperation should not exceed 2.5 times the number of failures per year beyond thefirst year. The ratio of first year failures to failures in subsequent years is known asthe infant mortality factor (IMF). The requirement is to have an IMF of less than2.5. †
DDM-2000 OC-12 Multiplexer circuit packs are subjected to an environmentalstress testing (EST) program. The purpose of the program is to eliminate early lifefailures, conduct failure mode analysis on defective circuit packs, and usecorrective action to make the product more reliable. All new circuit pack codes inmanufacturing are subjected to EST. However, based on field return data, whenthe early life failures for any circuit pack codes have been minimal and the infantmortality factor is below 2.5, these circuit pack codes may be subjected only tosampling EST.

DDM-2000 OC-12 System Reliability Predictions 10
Example:The unavailability of one two-way DS3 channel within one DDM-2000 OC-12 system configured tomultiplex DS3 to OC-12, located in an uncontrolled environment, is 0.499 minutes per year (that is,fraction of time per year when the DS3 channel is unavailable). The mean time between outage ofthe DS3 channel is 483 years (that is, average length of time until a DS3 outage occurs).
Notes:
1. Hardware failure rates are calculated per the RPP method, TR-NWT-000332, Issue 4,"Reliability Prediction Procedure."
2. The environmental factor for the CO = 1.0 and for the RT = 1.5, per TR-NWT-000332, Issue 4,"Reliability Prediction Procedure."
3. Bellcore criteria (Outage Requirements and Objectives) is based on TA-TSY-000418, Issue 3,"Generic Reliability Assurance Requirements for Fiber Optic Transport Systems." Outage is inminutes per year.
4. Mean time to repair is assumed to be 2 hours for the CO and 4 hours for RT environment.

11Commands and Reports 11
Overview 11
This chapter describes the command and report features of the American Standard Code for Information Interchange (ASCII) terminal interface to a DDM-2000 OC-12 Multiplexer. It provides detailed information about each command, as well as system report outputs and explanations.
Reason for Issue 11
This chapter provides the details of software commands for OC-3 Release 7.0. This release features Target ID Address Resolution Protocol (TARP) which provides for multi-vendor interworking. With this feature, some commands available in earlier releases are no longer applicable. Similarly, there are several new commmands in Release 7.0 not available in earlier releases. For additional information on TARP, please refer to the “About This Document” section.
Command Page Format 11
This chapter includes DDM-2000 commands that are presented as one- or multiple-page entires in alphabetical order. The name of each command appears at the top of each page.
Each entry is presented in a common format:
— The NAME part gives the name of the command and summarizes its funtion.
— The INPUT FORMAT provides the syntax for each command. Each command starts with a command name followed by a colon. Parameters follow the colon. Optional parameters are enclosed in square brackets [ ].
363-206-295Commands and Reports
11-2 Issue 1 December 1997
— The DESCRIPTION part provides detailed information about each command.
— The RELATED COMMANDS part identifies commands that affect or are affected by the named command or sets the conditions displayed by a report. Some commands are not affected by any other command and will not have this part included on the command page.
Entries which are to be typed exactly as shown are printed in bold type. System repsonses are printed in courier type. Descriptive names entry values are shown in italic type.
Input Format 11
All commands have a common input format:
command name[:Address][:parameters]
Address identifies a slot, channel, or operations interface within the shelf. In commands which require an address, it must appear immediately after the command name.
Parameters identifies a variable name assigned to some provisionable attribute of the command. The value of the parameter is defined on each command page.
Parameters are separated with commas (,). The parameters may be entered in any order, but they must be entered in the name=value format.
Brackets ([ ]) are not part of the command line. Parameters enclosed in brackets are optional. Default values are provided for these parameters.
Any command can be entered on a single line.
DDM-2000 is case sensitive. Commands may be entered in upper- and lower-case letters. Entries other than commands may be case sensitive (for example, passwords). DDM-2000 addresses and logins are sensitive to white space (that is, blanks between characters). For example, the address parameters “m1-all” and “m1- all” may be interpreted differently by DDM-2000. As a general rule, white space should not be included in commands.

Addresses 11
Table 11-1 specifies the valid addresses for slots, lines, ports, channels, paths, cross-connections, and operations interfaces. Where lists of items appear in braces { }, and one (and only one) of these items may be used to form the address.
Each address is made up of several components that are combined to indicate a specific location on the DDM-2000. The following list shows the potential values for each address component. Refer to this list when reviewing Table 11-1:
slot type: Possible values are: main, m, fn, ls, tg, sysctl, auxctl, tsi, userpanel, and all.
group: Possible values are: m, a, b, c, d, and all.
Note carefully in Table 11-1 when this value is followed by a dash (-) and when it is not.
slot within a group (abbreviated as slot):
Possible values are: 1-8, and all.
line: Possible values are: 1, 2 and all.
This identifies a line within a slot. Note carefully in Table 11-1 when all is not allowed.
STS-1: Possible values are: 1-12, and all.
special: Possible values are: cit, dcc, tbos, partlm, x25, env, cont, lan, and ref.
environmental alarm or control point (abbreviated as alm/cont point):
Possible values are: 1-21, and all.

Command Mode and Prompt Mode 11
There are two entry modes: command mode (no prompts) and prompt mode. In the command mode (the default), the command line and any user responses are terminated by the semicolon (;) or carriage return (<cr>).
The prompt mode is designed for users that are not familiar with DDM-2000. To enter the prompt mode, terminate any line with a carriage return ( or
key) or question mark (?). Prompts generally appear in the form:
Prompt Message [Default value]=
with the default value enclosed in square brackets ([..]). There are two types of default values:
Static default values, which assume the same value each time the command is invoked.
Current default values, which reflect the mode recent value entered into the system. In the case of an address containing the value “all”, the prompt will display the value [CurrentValues]. When “Current Values” is selected, the current setting of that parameter is not changed.
ENTERRETURN
363-206-295Commands and Reports
Issue 1 December 1997 11-7
To reenter the command mode from the prompt mode, answer the current prompt, then continue entering input on the same line after typing a comma (,). When the input is completed, terminating the command with a semicolon (;) will return the session to the command mode. If a command is terminated with a semicolon (;), the system will use default values for all optional parameters for which a value has not been given.
The help command provides in-context help during a dialog with DDM-2000. Help is provided automatically when an invalid input is entered and can also be requested anytime by typing a question mark (?).
Special Control Characters 11
The following characters have special meaning when used with DDM-2000:
— Backspace characters control H (^H), key is used to erase character input.
— At sign (@) is used to erase an entire line of input.
— Question mark (?) is used to get help and to enter prompt mode at any time.
— Comma (,) is used to separate parameters from each other.
— Equal sign (=) is used to separate parameter names from parameter values.
— Control T (^T) is the toggle command. See the toggle command page for additional details.
— Carriage return ( or key) or exclamation point (!) are used to end a line of input.
— Semicolon (;) is used to end a command. The system will use default values for all optional parameters for which a value has not been given.
— CANcel, DELete, and CTRL-x are used to abort a command which has been entered but has not yet started to execute. All commands can be aborted anytime before the “In Progress...” message is printed. Test commands (except test-sysctl) can be aborted at any time during execution using these keys. Reports may be aborted at any time using these keys.
— Colon (:) is used to separate the command name, address, and parameters.
Paged Reports 11
Reports are paged. When the end of the page has been reached, the prompt “more? [yes]=” is displayed if more report text remains. Page length can be set with the set-link command.

Confirmation Requests 11
NOTE: Some commands can be service-affecting if their default parameters are ignored.
After all parameters have been entered, a caution message followed by the command name, the selected values of parameters, and the prompt “Execute? (y/n or CANcel/DELete to quit)= is printed. To execute the command, enter “y” and carriage return. To change the value of any of the parameters, enter “n” and carriage return and you will be reprompted for all parameters. To abort the command, enter CANcel or DELete.
Output Descriptions 11
The output for most commands is described on the following manual pages. Refer to the “Detailed Alarm and History Reports” part of this section for more complete examples and explanations of the alarm and status report (rtrv-alm) and the history report (rtrv-hsty).
Alarm Level Prompt 11
When the system is ready to accept a new command, it prints the system prompt “<“. If there is an active alarm or status condition, the level of the highest level active alarm in the system is printed before the “<“. For example, the system prompt is “MN<“ when a minor alarm condition exists in the system.
Security 11
The option of system security is provided for DDM-2000 systems. Three privileged user logins and a maximum of 100 nonprivileged user logins, consisting of general users, maintenance users, and Reports-Only users, are available. Privileged users may set system security on all data communication channels (DCC) and each craft interface terminal (CIT) interface (using the set-secu command) and assign login and password pairs to general users (using the set-lgn command). General users may execute commands that are not restricted to privileged users and obtain reports. Maintenance users may only execute commands that access the system, extract reports, and execute maintenance functions. Reports-Only users may only obtain reports and ececute several basic commands.
When system security is enabled, all users are then required to enter a valid login and password pair to access the system.

Starting a CIT Session 11
Procedures in the “Operation and Maintenance” section of this manual describe how to “Connect a CIT and Establish a Session” with the DDM-2000.
CPro-2000 11
CPro-2000 is a software package from Lucent Technologies to help users of DDM-2000 Multiplexer systems set up and use an advanced, yet simple, craft operations environment on a personal computer using Microsoft* Windows*3.1 in the enhanced mode. CPro-2000 provides the user with the normal CIT access to DDM-2000 as well as a mouse-driven graphical user interface (GUI). The user may issue commands to DDM-2000 by using the mouse to select items from a menu and/or objects from the graphics display.
CPro-2000 Release 3.0 and later supports DDM-2000 OC-3,OC-12 and FiberReach Multiplexers, as well as FT-2000 OC-48 Systems. For complete information on CPro-2000, refer to the CPro-2000 User Manual, 190-253-101 (for CPro-2000 Release 3.0) or 365-576-1xx (for CPro-2000 Release 4.0 and later).
Commands 11
The following pages provide detailed information about the user interface commands supported by DDM-2000. Detailed report information is located at the end of this chapter.

AA SONET Overview A
Overview 0
This section briefly describes the Synchronous Optical Network (SONET).
History 0
In the early 1980's, the American National Standards Institute (ANSI) recognizedthe need for an optical signal standard for future broadband transmission. TheANSI T1X1 subcommittee began working on optical signal and interfacestandards in 1984. In 1985, Bellcore proposed a network approach to fibersystem standardization to T1X1. The proposal suggested a hierarchical family ofsignals whose rates would be integer multiples of a basic modular signal. Theproposal further suggested a synchronous multiplexing technique, leading to thecoining of the term Synchronous Optical NETwork (SONET).
The International Telephone and Telegraph Consultative Committee (CCITT) firstshowed interest in 1986. Conferences held through 1987 and 1988 resulted incoordinated specifications for both the American National Standard (SONET) andthe CCITT-International Standard, Synchronous Digital Hierarchy (SDH). Approvalof both sets of standards occurred in late 1988.
363-206-295A SONET Overview
A-2 Issue 1 December 1997
Basic Purpose 0
The basic purpose of SONET is to provide a standard synchronous opticalhierarchy with sufficient flexibility to accommodate digital signals that currentlyexist in today's network as well as those planned for the future.
SONET currently defines standard rates and formats and optical interfaces.These and other related issues continue to evolve through the ANSI committees.SONET ultimately will permit an optical midspan meet in a multivendorenvironment.
The American National Standard defines the following:
■ Optical parameters (ANSI* T1.106-1988)
■ Electrical parameters (ANSI T1.102-1993 Draft)
■ Multiplexing schemes to map existing digital signals (for example, DS1,DS2, and DS3) into SONET payload signals (ANSI T1.105-1991)
■ Criteria for optical line automatic protection switch (APS)(ANSI T1.105-1991)
■ Overhead channels to support standard operation, administration,maintenance, and provisioning (OAM&P) functions (ANSI T1.105-1991).
*
Technical Overview 0
SONET Signal Hierarchy 0
The SONET signal hierarchy is based on a basic "building block" frame called thesynchronous transport signal - level 1 (STS-1), as shown in Figure A-1 on thefollowing page. The STS-1 frame has a reoccurring rate of 8000 frames persecond. Each frame is 125 microseconds.
The STS-1 frame consists of:
■ 90 columns (each column is an 8-bit byte)
■ 9 rows.
* Registered trademark of America National Standards Institute
363-206-295A SONET Overview
Issue 1 December 1997 A-3
The STS-1 frame is transmitted serially starting from the left with row 1 column 1on through column 90, then row 2 column 1 through 90, continuing on, row-by-row, until all 810 bytes (9 X 90) of the STS-1 frame have been transmitted.
Since each STS-1 frame consists of 810 bytes and each byte has 8 bits, the framecontains 6480 bits a frame. There are 8000 STS-1 frames per second, at theSTS-1 signal rate of 51,840,000 (6480 X 8000) bits a second.
The first three columns in each of the nine rows carry the SECTION and LINEoverhead bytes. Collectively, these 27 bytes are referred to as transport overhead.
The remainder of the frame, columns 4 through 90, is reserved for payload signals(for example, DS1, DS3, and path overhead) and is referred to as the STS-1synchronous payload envelope (STS-1 SPE). The optical counterpart of theSTS-1 is the optical carrier level 1 signal (OC-1), which is the result of a directoptical conversion. The electrical counterpart of the STS-1 is the electrical carrierlevel 1 signal (EC-1).

SONET Layers 1
SONET divides its processing functions into three layers. These three layers areassociated with equipment that reflects the natural divisions in network spans.Figure A-2 shows these defined layers in a signal path. They include:
■ SECTION and Section Terminating Equipment - the transmissionspans between lightwave terminating equipment and the regenerators.The spans between the regenerators are also considered sections.Section terminating equipment provides regenerator functions andterminates the section overhead to provide single-ended operations andsection performance monitoring.
■ LINE and Line Terminating Equipment - the transmission span betweenterminating equipment (STS-1 cross-connections) that provides lineperformance monitoring. If there are no intervening repeaters, the lineterminating equipment also functions as section terminating equipment.
■ STS-1 and VT Path and Path Terminating Equipment - the transmissionspan for an end-to-end tributary (DS1 or DS3) signal that providesfunctions including signal labeling and path performance monitoring forsignals as they are transported through a SONET network. STS-1 pathterminating equipment can also provide cross-connections for lower rate(that is, DS1) signals. A virtual tributary (VT) is a sub-DS3 payload and isdescribed later in more detail.

Issue 1 December 1997 A-5
Each SONET layer has a set of overhead bytes as shown in Figure A-3. Thesebytes carry information used by various network elements.
■ Section Overhead contains information that is used by all SONETequipment including repeaters.
■ Line Overhead is used by all SONET equipment except repeaters.
■ Path Overhead is carried within the payload envelope.
— STS-1 path overhead remains with the STS-1 SPE until itsasynchronous signal is extracted (for example, DS-3) or until itsindividual VT1.5 signals are demultiplexed.
— VTN (N= 1.5, 2, 3, or 6) path overhead remains with the VTN untilits asynchronous signal is extracted.

SONET Frame Structure 1
The following pages provide more detailed information on the function of variousoverhead bytes for each SONET layer.
Section Overhead 1
■ Framing (A1, A2)
— Provides framing for each STS-1.
■ STS-1 ID (J0)
— Provides the order of appearance in a byte-interleaved STS-Nframe; for example, STS-1 #1, STS-1 #2......STS-1 #48. In futureapplications, this byte will provide a section trace function. Forinformation on STS-N signals, see the "Higher Rate Transport" partof this section.
■ Section Bit-Interleaved Parity (BIP-8) (B1)
— Provides SECTION performance monitoring and is calculated overall bits of the previous STS-N frame. Defined only for STS-1 #1 ofan STS-N signal.
■ Section Orderwire (E1)
— Provides a local orderwire for voice communication channelbetween section terminating network elements, such as repeaters.Defined only for STS-1 #1 of an STS-N signal.
■ Section User Channel (F1)
— Set aside for the user's purpose. Defined only for STS-1 #1 of anSTS-N signal.
■ Section Data Communications Channel (D1, D2, D3)
— Is a 192 kb/s message-based channel. Used for alarms,maintenance, control, monitoring, and other communication needsbetween section terminating equipment. Defined only for STS-1 #1of an STS-N signal.
363-206-295A SONET Overview
Issue 1 December 1997 A-7
Line Overhead 1
■ Line Pointer (H1, H2)
— Two bytes indicate the offset in bytes between the pointer actionbyte (H3) and the first byte (J1) of the STS-1 synchronous payloadenvelope (SPE).
■ Pointer Action (H3)
— One byte is allocated for frequency justification.
■ Line Bit-Interleaved Parity (BIP-8) (B2)
— This byte is for line performance monitoring. This byte is provided inall STS-1 signals within an STS-N signal.
■ Line Automatic Protection Switching (APS) (K1, K2)
— Two bytes used for APS signaling between line level entities. Inaddition, bits 6, 7, and 8 of K2 are used for line alarm indicationsignal (AIS) and line far-end receive failure (FERF). Defined only forSTS-1 #1 of an STS-N signal.
■ Line Data Communications Channel (D4 - D12)
— Is a 576 kb/s message-based channel.
■ Synch. Status (S1)
— In STS-1 #1, the S1 byte is for synchronization status messages,and only bits 5 through 8 are used.
■ Line REI (M0)
— The M0 byte is for STS-1 line far-end block error (FEBE), and onlybits 5 through 8 are used.
■ Line Orderwire (E2). Defined only for STS-1 #1 of an STS-N signal.
— One byte is allocated to be used as an express orderwire betweenline terminating equipment.
363-206-295A SONET Overview
A-8 Issue 1 December 1997
Path Overhead 1
There are two types of path overheads:
— STS-1 path overhead
— VT path overhead.
STS-1 Path Overhead 1
The STS-1 path overhead is assigned to and remains with the STS-1 SPE untilthe payload is extracted and is used for functions that are necessary to transportall synchronous payload envelopes.
■ STS-1 Path Trace (J1)
— Repetitively transmits a 64 byte, fixed length, string so that an STS-1path receiving terminal can verify its continued connection to theintended transmitter.
■ STS-1 Path Bit-Interleaved Parity (BIP-8) (B3)
— Provides each STS-1 path performance monitoring. This byte iscalculated over all bits of the previous STS-1 SPE beforescrambling.
■ STS-1 Path Signal Labels (C2)

VT Path Overhead 1
There is one byte of VT path overhead called V5. It occurs on every fourth frame;that is, 2000 times a second.
This byte provides for VT paths the same functions that B3, C2, and G1 providefor STS paths, namely:
■ Error checking
■ Signal label
■ Path status.
The bit assignments of the VT path overhead are specified in the following list andare illustrated in Figure A-4:
— Bits 1 and 2 are used for error performance monitoring (BIP-2).
— Bit 3 is a VT path far-end-block-error (FEBE) indication that is sent backtoward an originating VT PTE when errors are detected by the BIP-2.
— Bit 4 and Bit 8 are used for remote defect indication (RDI)
— Bits 5 through 7 provide a VT signal label.

SONET Multiplexing Procedure 1
SONET has provisions for multiplexing asynchronous DS1s, synchronous DS1s,and asynchronous DS3s. Refer to Figure A-5 and Figure A-6.
The first stage in multiplexing is mapping the input DS1 or DS3 tributary. In thecase of DS1 inputs, three time slots (DS0s) are added to the incoming signal thusbecoming a VT1.5. An asynchronous DS1 that fully meets the specified rate ismapped into the VT1.5 SPE as clear channel input since no framing is needed.
■ Each VT1.5 carries a single DS1 payload.
■ Four VT1.5s are bundled into a VT group (VT-G).
■ Seven VT-Gs are byte-interleaved into an STS-1 frame.
The VT-G to-STS-1 multiplex is a simple byte-interleaving process, so individualVT signals are easily observable within the STS-1. Thus, cross-connections andadd/drop can be accomplished without the back-to-back multiplexing/multiplexingsteps required by asynchronous signal formats. The structured VTs are nowmultiplexed into the STS-1 SPE, and the path, line, and section overhead areadded. The final multiplexing, as shown in Figure A-5, provides the scrambledSTS-N signal to the optical conversion stage.

SONET Demultiplexing Procedure 1
As shown in Figure A-6, demultiplexing is the inverse of multiplexing. Theunscrambled STS-1 signal from the optical conversion stages is processed toextract the section and line overhead and accurately locate the SPE. The nextstage processes the path overhead and demultiplexes the VTs. A standard DS3signal will be provided to the asynchronous network after path overheadprocessing. For DS1 signals, the individual DS1 VTs are then processed to extractVT overhead and, via the VT pointer, accurately locate the DS1 SPE. Finally,desynchronization of the DS1 SPE provides a standard DS1 signal to theasynchronous network.

Two key points should be noted at this time. First, the SONET frame is a fixed time(125 µs) and no bit-stuffing is used. Second, as shown in Figure A-7, thesynchronous payload envelope can float within the frame using byte-stuffing. Thisis to permit compensation for small variations in frequency between the clocks ofthe two systems that may occur if the systems are independently timed(plesiochronous timing). The SPE can also drift across the 125-µs frameboundary. SONET STS pointers are used to locate the SPE relative to thetransport overhead.

SONET Digital Multiplexing Schemes 1
Asynchronous Multiplexing 1
Currently, fiber optic facilities are primarily used to carry DS3 signals. The DS3signal consists of a combination of the following payload signals:
■ 28 DS1s
■ 14 DS1Cs
■ 7 DS2s.
Typically, 28 DS1 signals are multiplexed into a DS3 signal, using an M13 format.Refer to Figure A-8. M13 format is a process that includes bit-interleaving fourDS1 into a DS2 signal and then bit-interleaving seven DS2 signals into a DS3.The DS3 rate is not a direct multiple of the DS1 or the DS2 rates due to the bit-stuffing synchronization technique used in asynchronous multiplexing.
Identification of DS0s contained in any DS-N signal, except DS1, is complex andDS0s cannot be directly extracted. Thus, an asynchronous DS3 signal must bedemultiplexed down to the DS1 level to access and cross-connect DS0 and DS1signals.
Another disadvantage of the M13 format is there is no end-to-end overheadchannel for use by OAM&P groups.

Synchronous Multiplexing 1
SONET's method of byte-interleaving DS1s to a higher signal rate permitseconomical extraction of a single DS1 without the need to demultiplex the entireSTS-1 SPE. In addition, SONET provides overhead channels for use by OAM&Pgroups.
In SONET, a single asynchronous DS3 signal is mapped into an STS-1 SPE(Figure A-9).
Figure A-9. Synchronous Multiplexing
Virtual Tributary Signals 1
Sub-DS3 asynchronous signals (DS1, DS1C, DS2 and E1) are byte-interleavedinto a digital signal called a virtual tributary (VT). The VT is a structure designedfor the transport and switching of sub-DS3 payloads. Like the STS-1 signal, theVT signal has a floating pointer that allows each VT SPE to move within the VTstructure. There are four sizes of virtual tributaries (VT1.5, VT2, VT3, VT6).Higher rate payloads are transported as one or more concatenated STS-1signals.

Concatenated Mode 1
For services requiring multiples of the STS-1 rate, STS-1 path payloads may beshared to create a single broadband payload called a concatenated STS-Nc(OC-Nc). STS-1 signals are mapped into an STS-Nc SPE and transported as aconcatenated STS-Nc signal. This STS-Nc signal can be carried by an STS-N orOC-N (or higher level) line signal.
The STS-N signal is multiplexed, switched, and transported through the networkas a single entity. A concatenation indicator, used to show that the STS-1s of theSTS-Nc signal are linked together, is contained in the STS-1 payload pointer of allbut the first STS-1. The line and section overhead is sent on the first STS-1 andthe payload pointer for the first STS-1 is applied to all STS-1 signals in theconcatenated signal.
Figure A-10 shows an example of an STS-3c SPE. It consists of 3 x 87 columnsand 9 rows of bytes. The order of transmission is row by row, from left to right.

Higher Rate Transport 1
Higher rate SONET signals are created by byte-interleaving N STS-1 to form anSTS-N signal. The STS-N is then scrambled and converted to an optical carrier -level N (OC-N) signal. The OC-N has a line rate of exactly N times the OC-1 signal(see Table A-2).

1+1The 1+1 protection switching architecture protects against failures of the optical transmit/receive equipment and their connecting fiber facility. One bidirectional interface (twofibers plus associated OLIUs on each end) is designated "service," and the other isdesignated "protection." In each direction, identical signals are transmitted on the serviceand protection lines ("dual-fed"). The receiving equipment monitors the incoming serviceand protection lines independently, and selects traffic from one line (the "active" line)based on performance criteria and technician/OS control. In 1+1 both service andprotection lines could be active at the same time (service in one direction—protection inthe other).
1xN, 1x11xN protection switching pertains to circuit pack protection that provides a redundantsignal path through the DDM-2000 (it does not cover protection switching of an opticalfacility; see "1+1"). In 1xN switching, a group of N service circuit packs share a singlespare protection circuit pack. 1x1 is a special case of 1xN, with N=1. In 1x1 only one isactive at a time.

Dual 0x1 Cross-ConnectionIn a single-homed application, the DDM-2000 OC-3/OC-12 Multiplexer uses a dual 0x1cross-connection to map the VT1.5 channels between the DDM-2000 FiberReach OC-1and the DDM-2000 OC-3/OC-12 rings.

UnidirectionalA protection switching mode in which the system at each end of an optical span monitorsboth service and protection lines and independently chooses the best signal (unlessoverridden by an equipment failure or by an external request, such as a forced switch orlockout). In a system that uses unidirectional line switching, both the service andprotection lines may be active simultaneously, with one line carrying traffic in one directionand the other line carrying traffic in the other direction. For a 1+1 protection scheme theK1 and K2 bytes in the SONET line overhead are used to convey to the far end which linethe near end receiver has chosen, so that an "active" indication may be made at the farend.
