The central part of the Alcatel-Lucent 1511 MAX is the CMX board. It is the main con -troller board. Each tributary position is linked to the CMX with a direct high-speed link: the HSPTP (High-Speed TDM pt-to-pt). The CMX board provides four E1 uplink interfaces(without the need of a dedicated NxE1 tributary board). This interface is routed from the(optional redundant) CMX board(s) towards the CMXIO board where the physical con -nectors are provided. The four E1 interfaces can be used as a direct connection to a public/private network, or as a drop-insert in a chain of stations.

Technical data• cross-connect function provided by a non-blocking matrix• conference bridge• clock synchronization• power distribution through the system• compact flash memory to store persistent data• capacity = 32 K DS0’s• external interface: on the CMX board, there is an EIA/TIA-232 female connector for local

Voice Equipment Subsystems

F O R E I G N E X C H A N G E S U B S C R I B E R B O A R D ( F X S )

The Foreign eXchange Subscriber (FXS) tributary board provides the system with 15 physicalFXS voice 2-wire interfaces for voice communication.

An FXS interface behaves as a voice line interface of a PSTN exchange or a PABX:• DTMF dialing and pulse dialing• Detection of open or low–Ωic loop between a/b wires (on-hook, off-hook)• Detection of a or b wire to ground• Sending of ringing current• 12/16 kHz metering sending: for supplying the customer with in-band and on-line billing

information. • Hot-line connection between two dedicated users• Battery reversal• Calling Line Identification Presentation• Line interface parameters are software configurable.

The analog (frequency range 300Hz to 3400Hz) to digital audio encoding in the transmitdirection (Tx) is done according to the G.712 A-law and converted into a 64 kb/s timeslot.The opposite conversion is performed in the receive direction (Rx).

The FXS in an Alcatel-Lucent 1511 MAX is always combined with an Alcatel-Lucent 1511MAX with an FXO board, providing a mirror configuration to connect the POTS loops tothe PABX or PSTN exchange.

This is illustrated in Figure 5.

The E&M (EM) tributary board supplies the system with 15 physical analog E&M 2-wire or 4-wire interfaces. Examples of E&M applications are analog leased lines, teleprotection,public announcements, and omnibus lines (see section “Omnibus lines/party lines”).

E&M is a type of signaling used on analog telephone trunks. E&M connections use an E- and M-wire in addition to the wires that carry the voice.• E-wire = analog receive (ground detector)• M-wire = analog transmit (ground switch)


Because the voice can use either 2 wires or 4 wires, the total numbers of wires used on anE&M circuit is either 4 or 6. The E-wire is also called the Ear lead and the M-wire is alsocalled the Mouth lead.

The analog (frequency range 300Hz to 3400Hz) to digital audio encoding in the transmitdirection (Tx) is done according to the G.712 A-law and converted into a 64 kb/s timeslot.The opposite conversion is performed in the receive direction (Rx).

Two- or 4-wire mode is software selectable.

E&M signaling is applicable with the following actions:• Forwarding of the speech payload• Translate the E-wire status via the A-bit on the outgoing CAS signaling• Switch the M-wire to ground depending on the status of the A-bit of the incoming

CAS signaling

The timeslots of the Nx64 kb/s trail in an aggregate E1 signal or tributary signal do not needto be consecutive.

Multiplex Function

The multiplex function combines a number of voice or data channels in one aggregate E1 and has the following properties:• Up to 30 voice channels, if the standard PCM multiplexing is used. Timeslot 16 is used

for CAS signaling.• In case of data channels:

¬ up to 30 channels (structured)¬ 31 channels (unstructured)

• Combinations of the above possibilities.


Redundancy

A paramount feature for our customers is delivering a product with an availability > 99.999%,which makes redundant network systems essential. This section discusses how the Alcatel-Lucent 1511 MAX achieves this goal.

P O W E R R E D U N D A N C Y

The Alcatel-Lucent 1511 MAX is fed from a redundant DC source (-48V or -60V A+B). Thisis supplied to the redundant CMX boards, which in turn distribute the power to the tributaryboards realizing redundant feeding for each tributary board. So, power feeding redun dancyworks together with the optional redundancy of the CMX board. Power availability is monitoredon each tributary board, as well as on the CMX. The CMX also monitors the power level.

M AT R I X R E D U N D A N C Y

Cross-connect matrix redundancy is achieved by 1+1 non-reverting redundant CMX boardsin active/standby mode. Each tributary has an Equipment Protection Switch (EPS) towardsthe internal HSPTP. The EPS does the switchover from the path from the failing CMX to thestandby CMX. Each tributary board has an independent HSPTP to each of the CMX boards.

N E 1 T R I B U TA R Y R E D U N D A N C Y

Tributary redundancy is applicable for NE1 tributary boards and is achieved by the 1+1 non-reverting redundant NE1 boards in active/standby mode. One can configure 2 different NE1boards placed in any pair of adjacent slots in the NE as a redundant pair. The EPS does theswitchover, if needed.

Note: All other functions of the CMX board such as signaling, clock, synchronization and conferencebridging are also protected by implementing redundant CMX boards.

T R A I L P R O T E C T I O N

The trail protection uses the “internal redundant routing” feature and enables route protectionon the trail level. If used, the Alcatel-Lucent 1511 MAX transmits data via two different trails:at the receive side data coming from the healthy trail or, if this route fails, data is taken fromthe other side.

This internal redundant routing is implemented in each type of tributary. The redundantrouting of a 64 kb/s timeslot is illustrated in Figure 7, where the NE1 tributary board duplicatesthe active circuits and provides protection switching.

Signaling

In each tributary board and on the CMX board, a signaling module is responsible for the properhandling of communication control signals between two or more users (e.g., the setting upand tearing down of a connection). The users can be local or remote depending on the loca -tion in the network. It is also possible that a number of users are communicating in conference.To support this conferencing, the CMX provides a specific signaling module. The signalingmodule is also responsible for the interaction between a voice user and an exchange.

For every user (voice interface, data interface, conference network), a signaling module isprovided (see Figure 8). This module is responsible for the translation of events coming fromthe user into CAS signaling bits, and from CAS signaling bits into an event towards the user.Two examples of user events are on-off hook and ringing.

Clock and Synchronization

Stringent clock requirements are critical to the proper functioning of a carrier-grade TDMnetwork. The variation of a clock’s rate over time is conventionally divided into two components:jitter and wander. The Alcatel-Lucent 1511 MAX is in compliance with the ITU-T G.823recommendation, defining the permissible output jitter and wander for two levels: the lowerbeing the traffic interface (for transmission purposes on the tributary boards and the E1s onthe CMXIO board) and the more stable being the synchronization interface (used by theBITS output interface of the CMXIO board).

TDM networks rely on hierarchical distribution of timing. At the top of the hierarchy is anaccurate Primary Reference Clock (PRC). Next comes the SDH Equipment Clocks (SEC).At the bottom of the pyramid are Synchronization Supply Units (SSUs). The Alcatel-Lucent1511 MAX is situated at the SSU level, which is defined in ITU-T G.812. The source of theclock synchronization could come from a PRC, a SEC or another SSU.

The internal system clock of the Alcatel-Lucent 1511 MAX has an accuracy of 50 ppm. Theoscillator of this system clock should be synchronized to an external source. The synchronizationfunction is centralized on the CMX boards. The three available options for synchronizing theinternal system clock are:

External: Building Integrated Timing Supply (BITS) on one of the two external BITS 2 MHzG.703 clock input signals located at the CMXIO board. This would be the case, if theAlcatel-Lucent 1511 MAX is co-located at the CO. At a remote location, the BITS signalcould also be generated by a Global Positioning System (GPS) clock.

Extracted: Network clock extraction of the synchronization signal from one of the E1 ports ofa NE1 tributary board or E1’s of the CMX (e.g., if the Alcatel-Lucent 1511 MAX is deployedat a remote location).

Internal: Local XO clock use of the internal oscillator of the system.

The Alcatel-Lucent 1511 MAX has a programmable priority scheme that selects the bestavailable clock according to a priority scheme programmed by the operator and the perceivedquality (presence and stability) of the references. In the absence of any external synchroniza -tion source clock, the system goes into holdover mode, using its own free-running local XOclock as a time reference.

The clock signal is distributed to each individual tributary board. The CMX-boards alsoprovide a clock output for synchronization of external equipment at the BITS-O 2 MHzG.703 interface of the CMXIO board.


Conference Bridge

The conference bridge function is provided on the CMX board.

Its main function is to provide voice and signaling conference features. The number ofpartici pants can vary from 3 to 100. Participants can be added and/or removed dynamically.Up to 20 conferences can take place simultaneously. There are two types of conferences (see Figure 9):

Figure 9. Possible Conferences in the Conference Bridge

Master-slaveOne participant is considered as master and all other participants are slaves. The master broad-casts its information to all the slaves, and receives the combined information from all the slaves.The slaves only hear the master. The slaves cannot communicate with each other. In master-slave conference, two sub-phases can be distinguished: broadcast from master to slaves andcollect from slaves to master.

Full conferenceAll involved participants are equivalent. All members can communicate with each other.Every participant gets the combined information from all others, but himself or herself.

These 2 conference types are used for three types of resources:

Voice conferenceThis type is used for speech applications. Each channel is transformed to linear form, added tothe others, if applicable, and transformed back to PCM form. G.712 A-law coding is supported.Overflow of the add process is monitored, attenuating the relevant channel if required.

Signaling conferenceThe signaling conference is part of a voice conference. The CAS signaling of each member is terminated in the conference signaling engine, which generates the CAS signaling to thedestinations. This kind of application can serve, for example, to activate a bell or other indicatorat each participant’s location by means of external equipment. The first one to pick up thetelephone alarms all others, and the indication remains on until the last one hangs up.

Data conferenceThe data conference is used for both 64 kb/s and Nx64 kb/s applications. Data conference isonly supported in the master-slave mode. It can be used, for example, to connect one mastercomputer with a series of other computers, where the master sends to all slaves; however, onlythe one addressed is allowed to answer. Another example, illustrated in Figure 10, is a point-to-multipoint data conference. In this configuration, the Alcatel-Lucent 1511 MAX conferencebridge, which functions in the master node, is combined with the Alcatel-Lucent 1511 MAXcross-connect function in another node.

Figure 10. Point-to multipoint data conference

Omnibus Lines or Party-lines

The omnibus line system allows intelligent telephone sets to make selective calls among apredefined number of them, without the intervention of a Public Switch or PABX.

The telephone sets can be located along a utility network. Two categories of omnibus linesexist: a “dispatcher” system and a “full conference” system.• Dispatching system: one master of the group. The master can call any individual slave

telephone set or can call a group out of the omnibus line. The slaves can only call themaster. In the same way, during the conversation, the master can talk to every slave andcan listen to all the slaves; the slave can listen only to the master.

• Full conference system: all parties are at the same level. Every party can call an individualother party or a selected group out of the omnibus line. All parties can listen to all parties.

The dedicated telephone sets are connected to 4 wire E&M ports of Alcatel-Lucent 1511MAXs. The Alcatel-Lucent 1511 MAX does the AD/DA conversion, maps the voice signalson a 64 kb/s timeslot. The E1s are transported from the different sites to one central site. Inthe central site’s Alcatel-Lucent 1511 MAX, the 64 kb/s channels are cross connected to theconference bridge of the Alcatel-Lucent 1511 MAX. By giving the right instruction to theconference bridge, it realizes the dispatching connection or the full conference connection.This application is illustrated in Figure 11.

Network Management

The network management of the Alcatel-Lucent 1511 MAX is illustrated in Figure 12.

For the initialization of the Alcatel-Lucent 1511 MAX, the setup of IP network parameters isdone with the CLI (Command Line Interface) via an EIA/TIA-232 cable connected to theAlcatel-Lucent 1511 MAX.

After this initialization, the Alcatel-Lucent 1511 MAX can be managed via differentmanagement systems:

• Web-based Craft TerminalThe WebCT is a web-based craft terminal for the Alcatel-Lucent 1511 MAX. The craftterminal is typically a PC with a normal web browser. All management information is handledthrough web pages. The web server inside the 1511 MAX responds to HTTP-protocol basedmanagement requests to display or update data in the 1511 MAX.

• Alcatel-Lucent 1511 Element Manager (EM) The Alcatel-Lucent 1511 EM is a dedicated software platform running on a server. Withthe Alcatel-Lucent 1511 EM server, several operators can manage the NE simultaneouslyfrom a workstation (Alcatel-Lucent 1511 EM client). The Alcatel-Lucent 1511 EM is asystem targeted for a Network Operation Center enabling 24x7 management of the Alcatel-Lucent 1511 MAX resources. The main purpose of the Alcatel-Lucent 1511 EM is to provideadvanced and centralized multi-NE management. The Alcatel-Lucent 1511 EM can manageup to 2,000 fully equipped 1511 MAX’s. For smaller networks (less than 300 nodes), theAlcatel-Lucent 1511 EM can run on a PC. The communication protocols between the Alcatel-Lucent 1511 EM and the Alcatel-Lucent1511 MAX are SNMP, HTTP and FTP. The communication between the client and theAlcatel-Lucent 1511 EM server utilizes the HTTP protocol. The user interface is identicalto the WebCT interface, though it has additional functionality to manage a network ofAlcatel-Lucent 1511 MAX’s.

• Third-Party Management ToolOptionally, an SNMP-based, third-party management tool, or higher layer Operations SupportSystems (OSS)/Business Support Systems (BSS), can manage the Alcatel-Lucent 1511 MAXNEs, in combination with the WebCT, or in communication with the Alcatel-Lucent 1511EM. The communication protocol between the Alcatel-Lucent 1511 MAX or the Alcatel-Lucent 1511 EM and the third- party management tool is SNMPv2c or SNMPv3. The third-party management tool requires an Alcatel-Lucent 1511 MAX dedicated software plug-in.

All three tools are connected to the Alcatel-Lucent 1511 MAX over a data communicationnetwork via an E1 or Ethernet interface of an Alcatel-Lucent 1511 MAX.

Listed below are a few examples of applications that address the needs of vertical marketcustomers for high reliability and proven technology in their utility networks.

Transport — Railway Utility

Railway, light rail, and metro operating companies rely on a carrier-grade digital transmissionnetwork for their operations. Mission-critical applications — clock synchronization, controllinglevel crossings and line-side signaling, interlocking equipment, traction power teleprotection,operational telephony and radio, line-side signal post telephones, emergency call points,supervisory control and data acquisition (SCADA) systems, CCTV surveillance, etc. (seeFigure 13) — are all critical to railway operations and safety, and require a highly reliabletelecommunications network.

As a primary business access multiplexer, the Alcatel-Lucent 1511 MAX, provides access for the applications described above via the different voice, low-speed and high-speed datatributary ports. These include the 64 kb/s co- and contra-directional G.703, Nx64 kb/s V.35or X.21, fractional E1 G.703, low-speed rate adapter, alarm collection and many more.

In a central site such as a railway operator’s control center, the Alcatel-Lucent 1511 MAX 1/0cross-connect provides connections between the various applications along the railway lineand the servers in the control center. The Alcatel-Lucent 1511 MAX fulfills the strongestrequirements of the Railway EMC/EMI specification EN50121-4.

Energy — Power Utility

Utility companies are uniquely positioned to leverage their established rights-of-way (ROW)to accommodate their enterprise network requirements. An example of a key application thataddresses the requirements of a utility network is the digital transmission backbone applicationdepicted in Figure 14. This type of application is common in utility networks where voice anddata circuits from various locations are inserted and dropped along the route. The Alcatel-Lucent 15xx products support linear drop-and-insert ring mode, as well as point-to-point config-urations. Figure 14 depicts a typical utility network where connectivity between a central siteand numerous remote sites is required. Typical requirements include voice services, dataterminal-to-server connections, telemetry monitoring, teleprotection switching and SCADAtelecontrol.

Figure 14. Alcatel-Lucent 15xx Power Utility Application

As an access multiplexer, the Alcatel-Lucent 1511 MAX, , provides access for the applicationsdescribed above via the different voice, low-speed and high-speed data tributary interfaces.These include the 64 kb/s co- and contra-directional G.703, Nx64 kb/s V.35, V.35 or X.21,fractional E1 G.703, low-speed rate adapter, alarm collection, and many more.

Again, in the power utility operations control center, the Alcatel-Lucent 1511 MAX grooms64 kb/s TS’s from any E1 (input) to any E1 (output). The Alcatel-Lucent 1511 MAX is equallyable to broadcast a 64 kb/s TS of an incoming E1 to many TS’s of outgoing E1s. The Alcatel-Lucent 1511 MAX is fully protected and has a non-blocking matrix, making it ideally suitedfor deployment in a centralized (common) location.

Energy — Oil and Gas Exploration and Production

Oil and gas exploration companies have network requirements similar to other vertical markets.They require reliable, robust networking solutions for their internal operational traffic. Avariation on the railway or high-voltage power line application is often a good fit for thesehigh-value customers to deliver mission-critical data to remote locations. Producers of oil andgas can deploy Alcatel-Lucent 1511 MAX’s to extend the reach of their network to remotelocations along the pipelines and even on offshore drilling platforms, while providing absolutereliability. The Alcatel-Lucent 1511 MAX is used in combination with the Alcatel-LucentOptical Multiservice Node (OMSN) together with the Alcatel-Lucent 9600 series SDHmicrowave radios that provide the wireless portion of the network.

Alcatel-Lucent 1511 MAX applications, such as a SCADA distributed measurement andcontrol (DMC) system in the control room are connected to the block valves or flow controlremote terminal units (RTUs) along pipelines or on wellheads. The Alcatel-Lucent 1511MAX also interconnects emergency call points (hotlines), VHF/UHF radio repeaters, beaconingsystems, etc. with the different tributaries for voice, low-speed and high-speed data, etc.

Defense and Security

In the defense and security segment, customers such as ministries of defense (armed forces,military air traffic control), law enforcement agencies, homeland security/national safetyservices (police, fire brigades, civil protection, ambulances, etc.) all require a highly reliableand robust backbone and access network to support security- and safety-critical applications.Applications, such as VHF/UHF/TETRA/PTT radio, voice communications, data communica -tions, data acquisition (radar, border control, sensors, etc.) run over such a reliable and securemultiservice but cost-effective network.

Figure 16. Alcatel-Lucent 15xx Defense Application

Government — Air Traffic Control Authority

Air traffic control authorities also require the highest level of reliability for mission-criticalvoice and radar data traffic.

Figure 17 depicts a typical network used by air traffic control authorities to meet their stringentavailability requirements, because safety is paramount. The Alcatel-Lucent 1511 MAX is usedto convey radar data from the different air traffic control radar sites towards the central air trafficcontrol tower. The same network is used to convey ground voice communication inter facingwith ground-to-air radio communications equipment and TETRA emergency communi cations,

Digital TV and Radio Broadcasting

Broadcasting operators are investing in the migration from analog to digital TV and radiobroadcast systems. At the same time, they need to upgrade their transmission network to ahighly reliable network. A broadcasting network typically consists of a contribution network(from mobile or regional production studios to a main production/play-out studio) and adistribution network (from the play-out studios to the digital TV (digital video broadcast —terrestrial [DVB-T]) and radio (digital audio broadcasting [DAB]) broadcast transmitters. TheAlcatel-Lucent 1511 MAX is used to flexibly drop and cross-connect channels to particular(regional) broadcast transmitters, and to control TV and radio coders/decoders (codecs).

Private Line/Leased Line

One of the main applications of the Alcatel-Lucent 1511 MAX is private line/leased- lineservices (shown in Figure 19), which allow the service provider to offer customers customerpremises equipment (CPE) that is connected into the network to backhaul data from the remotesite to the headquarters. Often, this is used for LAN-to-LAN or LAN-to-host connectionswhere the remote site is accessing database information, headquarters-controlled applications,and the Internet. The Alcatel-Lucent 1511 MAX business access multiplexer can be used invoice, data, or integrated voice and data networking, and may be deployed in point-to-point,point-to-network, and point-to-multipoint topologies.

Figure 19 depicts a typical leased-line network requiring business site connectivity. Commonrequirements include dedicated voice services, data terminal-to-server connections, and remoteLAN connectivity. Bandwidths among the various locations are leased from telecom carriers.These lines are connected to the local point of presence (PoP) within the enterprise network.

Figure 19. Alcatel-Lucent 15xx Leased Line Application

Mobile Aggregation Networks

The Alcatel-Lucent 1511 MAX offers the opportunity to take advantage of the aggregationnetwork support requirements of mobile networks.

Figure 20 illustrates how, in a 2G and/or 3G mobile network, the Alcatel-Lucent 1511 MAXis used to consolidate and groom voice and data traffic from many base transceiver station(BTS) or radio network controller (RNC) sites onto an aggregate E1 for transport to the

mobile switching center (MSC). The Alcatel-Lucent 1511 MAX has a fully interconnected,non-blocking switching matrix that allows connection of incoming, underutilized BTS E1lines to be switched to any time slots on the aggregate E1 going to the MSC.

Equally, in railway environments, traffic from GSM-R (a railway variant of GSM for theiroperational needs) base stations can be groomed to aggregate E1’s. In other vertical segments,such as public safety, airports, oil & gas, metros, harbors, etc. traffic from TETRA, push-to-talk (PTT) or maritime mobile radio base stations is equally groomed.
