PrecautionsThroughout this document, there are important precautionary statements used to warn of possible hazards to persons or equipment. A precaution identifies a possible hazard and then explains what may happen if the hazard is not avoided. The Danger, Warning, and Caution statements should be followed at all times to ensure safe and proper installation, operation, and reliability of the prod-uct. When multiple precautions are present, they are listed in order of severity as follows:

Danger! Indicates that a certain risk is associated with the task that will cause severe per-sonal injury, death, or substantial property damage if the procedure is not adhered to as written.

Warning! Indicates that a certain risk is associated with the task that can cause personal injury, death, or substantial property damage if the procedure is not adhered to as written.

Caution! Indicates that a certain risk is associated with the task that can or will cause per-sonal injury or property damage if the procedure is not adhered to as written.

General Safety PrecautionsThese precautions will be found throughout the document whenever the optical cards or other sys-tem components are being discussed.

Danger! Never look into the end of an optical fiber. Exposure to invisible LASER radiation can cause serious and/or permanent damage to the eye or even blindness. Verify the optical source is disabled through the use of an optical power meter before handling optical fibers. Use of controls, adjustments, or procedures other than those specified within this document may result in hazardous laser radiation expo-sure.

Caution! Electrostatic Discharge (ESD) sensitive devices. ESD can cause catastrophic fail-ure or degraded life and performance of a device. Use an anti-static wrist strap connected to a properly grounded source before contacting any electronic devices.

Chapter 1 Introduction

The TE-2020 is a modular SONET platform that supports Ethernet and SONET interfaces ranging from OC-3 to OC-192. The TE-2020 SONET ADM supports two levels of modularity: (1) shelf level and (2) card level.

With shelf level modularity, all NE installations require that a TE-2020 Main Shelf be installed. The OTS2, DS3/EC1 Tributary Shelf (ETS1), and ETS2 can optionally be installed as part of an NE installation offer-ing the shelf level modularity. The OTS2 offers additional interfaces beyond the OTS1, and the ETS2 offers DS1 and FastE interfaces in addition to DS2 interfaces (ETS1 only has DS3 availability)

Additionally, each type of shelf can be equipped with various Physical Layer Modules (PLMs) to support different rates and formats of user interfaces. These PLMs offer card level modularity.

This document describes the hardware available for the TE-2020 family of products. It includes diagrams, power and size information as well as functional block diagrams for each piece of hardware available in the first release phase of the Turin Networks TE-2020 product.

It takes a pair of cables to create a fully redundant link between the TE-2020 Main Shelf and a tributary shelf. There are two types of LEI cables (A and B) that make up one complete LEI connection. Each LEI A connector on the shelf has a female DB-15 connector which allows only an LEI A cable equipped with a male end to be connected to it. Each LEI B connector on the shelf has a male DB-15 connector allowing only a female connector on the LEI B cable to be connected to it.

The proper number of LEI cable pairs to connect between the main shelf and a tributary shelf can be deter-mined by referencing the TE-2020 Applications and Engineering Manual (WR-D2020-APP-040000). For additional information on inter-shelf LEI cable routing, refer to Chapter 21 Local Equipment Interconnect Cables.

2.7 Wire-Wrap Pin FieldThe Wire-Wrap pin field is located on the back of the shelf on the right-hand side as shown in Figure 2-7. The wire-wrap posts are used for access to many functions which are described in detail in the TE-2020 Applications and Engineering Manual (WR-D2020-APP-040000) and are briefly described in the sections below.

2.7.1 Environmental Input Pins

Sixteen environmental input pins are provided so that the TE-2020 Main Shelf can monitor alarm outputs and actions from other equipment at the same site. The user can provision alarms to correspond to the input control pins.

The environmental input pins are all single ended inputs that can detect contact closure to ground (or return) on the external equipment. Under normal conditions, the circuit is open at the external device; under detect conditions, the circuit is closed. The environmental input pin detects a switch closing for the alarm circuit and creates a configured alarm. An example of an environmental alarm would be an open door of the facility where the TE-2020 Main Shelf is installed. Refer to Figure 2-8 for Environmental Input pin locations

Figure 2-8 Environmental Input Pins

2.7.2 External Output Control Pins

The equipment external output control pins are used to control equipment such as generators or air condi-tioners located at the same site. Under normal conditions, the circuit is open; in operated state, the circuit provides a path to ground (or return). The output control pin creates an open circuit with external equip-ment. When the user initiates a command, the circuit closes on the TE-2020, becoming a ground (or return)

2.7.4 Alarm Cut-Off (ACO) Control Pins

The Alarm Cut-Off (ACO) feature enables the TE-2020 to cut off the office audible alarm indications without changing the local alarm indications. The NE will remain able to transmit its current alarm or sta-tus condition if requested by the management system or other external command source.

The TE-2020 can silence the audible alarms for critical, major and minor alarms by an external piece of equipment at the same location by using the ACO feature. This ACO interface is a two pin connection that is controlled by an external device by changing from an open circuit to a closed circuit by shorting the two pins together. Refer to Figure 2-11. The ACO function is also available by pressing the ACO button on the front of the fan tray on the TE-2020 Main Shelf. The ACO can be connected at any time, but is generally connected at the time of initial installation.

2.7.5 BITS Input/Derived Output Pins and Frame Ground

BITS Input 1 and 2 are external DS1 reference signals from Stratum 3 or better synchronization supply sources. External synchronization reference from a BITS clock is the preferred mode of synchronizing SONET network elements.

The TE-2020 Main Shelf can also distribute derived SONET-based synchronization signals via the BITS 1 and 2 output pins using DS1s derived from a terminating OC-n synchronization reference.

Two frame ground pins are included in this section because of their common use as shield termination for DS1 cables.

2.8 Front RJ-45 Craft User PortThe user can access an NE via an Ethernet port located on the front of the TE-2020 Main Fan Tray. This port uses a standard NAPT (Network Address Port Translation) which enables a user to connect to any Turin Networks TE-2020 without any additional IP configuration changes to the interfacing computer device. In essence it creates a standard IP configuration that converts IP packets as they cross the boundary between nodes within the network. The user can plug into one node and retrieve information from any other node within its network. Every ETH-F address is configured the same from the factory and it is rec-ommended not to change this configuration.

below.

3.4.1 Power Selection/Conversion

The TE-2020 Main CCT accepts redundant (A and B) -48Vdc nominal power inputs from the rear connec-tors on the backplane and shares both A and B inputs for use on the system. The input voltage is then con-verted to board level voltages (i.e., +1.8Vdc, +2.5Vdc, and +2.0Vdc) and distributed to the cards and components that require them.

3.4.2 Microprocessor Core

The microprocessor core on the TE-2020 Main CCT provides the necessary performance for handling the required configuration, management, routing, and real-time processing responsibilities. Two microproces-sors are utilized to ensure adequate processing capacity and to isolate deterministic processing from non-deterministic processing. One processor handles SONET processing functions while the other handles control plane processing functions.

3.4.3 Software Storage and Upgrade

The TE-2020 Main CCT provides active and non-volatile memory for the storage of system software. The active memory is for software downloads and database backup and recovery. The non-volatile memory stores the database and current application software for the network element.

3.4.4 Temperature Monitoring

Each TE-2020 Main CCT contains five temperature sensors on the top of the board, and three temperature sensors on the bottom of the board. The system will alarm in the event that the temperature exceeds a pre-defined level.

3.4.5 Reset Control

Each TE-2020 Main CCT contains a reset/enable button on the front of the card, at the end of the middle protruding piece in between the PLM slots. Refer to Figure 3-2. This button pushed by itself has no effect on the system. The reset/enable button must be pushed in conjunction with the alarm cut-off (ACO)/Reset (RST) button on the TE-2020 Main Fan Tray in order to reset the TE-2020 Main CCT.

NOTE: For the reset operation to function properly the reset/enable button and the Alarm Cut-Off/Reset button must be depressed simultaneously for between 1 and 3 seconds.

Figure 3-2 TE-2020 Main CCT Front View



3.4.6 Protection Switching

The CCT is responsible for detecting and properly switching to a redundant source for protected equip-ment failures within the shelf. The equipment failures can be on PLMs or on the CCTs themselves.

3.4.7 Synchronization

Each TE-2020 Main CCT contains a synchronization unit which provides a Stratum 3 synchronization ref-erence for holdover. Circuitry to recover and distribute timing from any of the PLMs or BITS inputs is also provided on the CCTs.

3.4.8 External Inputs and Controls

The TE-2020 Main CCT controls the circuitry that drives the external control connectors and the circuitry that monitors the external alarm connections.

3.5 1920 x 1920 STS-1 Cross-connectThe cross-connect matrix provides a non-blocking 1920 x 1920 STS-1 cross-connect allowing any-port-to-any-port connection flexibility for STS-1, STS-3c, STS-12c, STS-48c, and STS-192c connection types on the TE-2020 Main Shelf, or any of the tributary shelves. All cross-connects are made through the TE-2020 Main Shelf except for hair-pinned connections on the OTS2 which are made locally on the tributary shelf.

3.5.1 2.5 Gbps and 5 Gbps VT1.5 Cross-connect

The OTS2 CCT may be ordered with a VT1.5 cross-connect option ineither 2.5 Gbps or 5 Gbps capacity. The VT1.5 cross-connect is used to support VT1.5 UPSR capability.

3.6 LEI Termination and ProtectionThe TE-2020 Main CCT has protected electrical interfaces for interconnection to other Turin Networks tributary shelves. Each LEI cable is capable of carrying two 2.488 Gbs bidirectional signals up to 10 meters. The LEI cables connect to the passive backplane at the rear of the shelf. The CCT is responsible for selecting the appropriate signal to use for data and management traffic as part of the protection mechanism.

3.7 Connectivity

3.7.1 Connection to Physical Layer Modules

The PLM connector mates with the leading edge (inserted first in the PLM slot) CCT connector on the PLM. This interface provides power as well as data and management connectivity between the CCT and the PLMs.

3.7.2 Connection to Backplane



The backplane connector on the leading edge (inserted first in the CCT slot) of the CCT provides power as well as data and management connectivity between pairs of CCTs and the other shelves.


Chapter 4 TE-2020 Main Fan Tray

The TE-2020 Main Shelf is designed to accept a single fan tray. This fan tray comprises twelve individual fans that operate individually. The failure of any of the individual fans will result in an alarm condition, but the fan tray unit will continue to operate. The fan tray is necessary for proper operation. Figure 4-1 below shows the TE-2020 Main Fan Tray.

Figure 4-1 TE-2020 Main Fan Tray

4.1 Functional DescriptionThe fan tray consists of an air intake for the shelf, status LEDs, alarm cut-off (ACO)/reset (RST) button,

front user management port, twelve fans, input/output block, and a 2 RU fan filter. Communication between the CCT and the module is via the backplane.

Under normal operation conditions, the fan tray will regulate the internal system temperature and does not require attention.

If a single fan fails, a minor alarm is issued. If two fans fail, a critical alarm is issued. The remaining fans continue to operate. The system is designed to accommodate two fan failures and maintain normal opera-tion.

4.1.1 Front Panel

The front panel of the TE-2020 Main Fan Tray shown in Figure 4-2 consists of the air intake, status LEDs, alarm cut-off (ACO)/reset button, and the front user port.

Figure 4-2 TE-2020 Main Fan Tray Front Panel

4.1.2 Air Intake

The air intake for the TE-2020 Main Shelf is on the front of the TE-2020 Main Fan Tray, and on the left side of the 23-inch shelf air intake. The front fan tray intake is covered with a wire mesh shield. In 23” applications, an additional filter is used which covers the front and side of the extension air intake as shown in Figure 4-3.



Figure 4-3 23” Extension Air Filter

4.1.3 LEDs

The Fan Tray LEDs are for the Upper TE-2020 Main CCT board (U), the Lower TE-2020 Main CCT board (L), and the NE Status (STAT). The LEDs will be green if operations are normal. If the LEDs become red or yellow, an alarm has been issued. The alarm status colors are shown in Table 4-2 and Table 4-3 .

4.1.4 Alarm Cut-Off (ACO)/Reset (RST)

The ACO/RST button is located on the front of the TE-2020 Main Fan Tray.

The Alarm Cut-Off is used to cut off the office audible alarm indicators. The NE will remain able to trans-mit its current alarm or status condition if requested by the management system or other external command source. In general, centralized indications should not be affected by the ACO. It retires the central office (CO) alarm audible indicators without clearing existing indicators on the NE. The ACO/RST button must be depressed for five seconds to issue an ACO.

The ACO/RST button will issue a lamp test if pressed by itself and immediately released.

The Alarm Cut-Off (ACO)/Reset (RST) button can be pushed in conjunction with the reset button on a TE-2020 Main CCT to reset the TE-2020 Main CCT.

Caution: If both the TE-2020 Main CCT reset button and the TE-2020 Main Fan Tray button are pushed together, traffic can be dropped.

4.1.5 User Port

The user can access an NE via an Ethernet port located on the front of the TE-2020 Main Fan Tray. This interface port can be accessed directly using a standard Ethernet cable.

Figure 4-4 User Interface Wiring Scheme

4.1.6 2 RU Fan Filter

The 2 RU fan filter (WR-PFLTR-002-00000) runs the length of the fan tray to the left of the fans if facing the TE-2020 Main Shelf. It is designed to optimize the air filtering process. The fan filter has an air-flow direction indicator arrow label, and it should be installed per the indicator. Replacement chassis filters can also be ordered (WR-PFLTR-002-00000 for single filters, or WR-PFLTR-X02-00000 for a pack of 10 fil-ters). It is recommended that the fan filter be changed every six months when operating under normal Cen-tral Office conditions. The filter cannot be cleaned.



Figure 4-5 2 RU Fan Filter

4.1.7 2 RU Chassis Filter

Chassis filters may be used on 23” rack mount applications when environmental conditions dictate higher filtration requirements for the equipment (environments exceeding GR-63 specifications for environmen-tally controlled spaces). The chassis filters are an optional upgrade for these conditions and not part of a standard 23” chassis assembly.

On 23” shelves, a shelf extension is installed on the left side which provides an air intake vent allowing for proper air flow through the chassis. The chassis filter (WR-KFLTR-2RU-00000) can be installed on the left side of the 23” chassis extension as shown in Figure 4-6. Replacement chassis filters can also be ordered (WR-PFLTR-005-00000 for single filters, or WR-PFLTR-X05-00000 for a pack of 10 filters). These filters should be changed every six months when operating under normal Central Office conditions. The filter cannot be cleaned.

5.3 Power Supply and ReturnThe OTS2 provides redundant (A and B) -48Vdc power connectors to supply power to the system. Each connector has a removable plug to aid in the installation of Supply and Return wires. The A connector is labeled -48A for Supply and RTN for Return. The B connector is labeled -48B for Supply and RTN for Return. Refer to Figure 5-6.


The maximum, minimum, and nominal input voltages (as measured across -48 and RTN) are shown in Table 2-3.

Table 5-3 A and B Power Connector Pinouts

5.4 Frame GroundThe OTS2 provides a Frame Ground connection on the back of the shelf. This Frame Ground is used to ter-minate connector shields and is used on the system in ESD protection mechanisms. The Frame Ground is shown in Figure 5-6 between the power connectors and should be connected to the Frame or Chassis Ground for the bay.

5.5 BackplaneThe OTS2 has a passive two rack unit backplane that provides connectivity between the CCTs and optical PLMs, power distribution for all of the shelf plug-ins, and connectivity between the external connectors, CCTs and optical PLMs.

B -42.5 Vdc -48 Vdc -56.5 Vdc



To provide data and management traffic expansion into other shelves, the OTS2 provides connectivity for up to four LEI cable pair connections.

It takes a pair of cables to create a fully redundant link between the OTS2 and the TE-2020 Main Shelf. There are two types of LEI cables (A and B) that make up one complete LEI connection. Each LEI A con-nector on the shelf has a female DB-15 connector which allows only an LEI A cable equipped with a male end to be connected to it. Each LEI B connector on the shelf has a male DB-15 connector allowing only a female connector on the LEI B cable to be connected to it.

The proper number of LEI cable pairs to connect between the main shelf and a tributary shelf can be deter-mined by referencing the TE-2020 Applications and Engineering Manual (WR-D2020-APP-040000). For additional information on inter-shelf LEI cable routing, refer to Chapter 21 Local Equipment Interconnect Cables.

board level voltages (i.e., +1.8Vdc, +2.5Vdc, and +2.0Vdc) and distributed to the cards and components that require them.


The microprocessor core on the OTS2 CCT provides the necessary performance for handling the required configuration, management, routing, and real-time processing responsibilities.


The OTS2 CCT provides non-volatile memory for the storage of system software. The non-volatile mem-ory stores the database and current application software for the network element.


Each OTS2 CCT contains five temperature sensors on the top of the board, and three temperature sensors on the bottom of the board. The system will alarm in the event that the temperature exceeds a predefined level.

6.3.5 Reset Control

Each OTS2 CCT contains a reset/enable button on the front of the card, at the end of the middle protruding piece in between the PLM slots. Refer to Figure 6-2. This button pushed by itself has no effect on the sys-tem. The reset/enable button must be pushed in conjunction with the Reset (RST) button on the OTS2 Fan Tray in order to reset the OTS2 CCT.

NOTE: For the reset operation to function properly the reset/enable button and the Alarm Cut-Off/Reset button must be depressed for between 1 and 3 seconds.

Figure 6-2 OTS2 CCT Front View


The OTS2 CCT is responsible for detecting and properly switching to a redundant source for protected equipment failures within the shelf. The equipment failures can be on PLMs or on the CCTs themselves.

6.3.7 Synchronization

The system clocking s performed by the clock unit on the Main Shelf CCT only. The OTS2 CCT merely recovers the timing information from the LEI and distributes it to the shelf components.



6.3.8 2.5 Gbps and 5 Gbps VT1.5 Cross-connect

The OTS2 CCT may be ordered with a VT1.5 cross-connect option in either 2.5 Gbps or 5.0 Gbps capac-ity. The VT1.5 cross-connect is used to support VT1.5 UPSR capability.

6.4 SONET/SDH MappingAll of the SONET/SDH interfaces from the various PLMs are mapped to the STS-48 of the LEI in both the transmit and receive direction. The LEI traffic will be cross-connected at the TE-2020 Main Shelf.

6.5 Local HairpinningHairpinned connections (connection between facilities on the same tributary shelf) are made by the matrix on the OTS2 shelf. This does not occupy bandwidth on the LEI connections to the TE-2020 Main Shelf.

6.6 Local Equipment Interconnect (LEI)The OTS2 CCT has protected electrical interfaces for interconnection to the TE-2020 Main Shelf. Each LEI cable is capable of supporting four STS-48 (2.488 Gbs) bidirectional signals for up to 10 meters. The OTS2 CCT is responsible for selecting the appropriate signal to use for data and management traffic as part of the protection mechanism.

6.7 Connectivity

6.7.1 Connection to Physical Layer Modules

The PLM connector mates with the leading edge (inserted first in the PLM slot) CCT connector on the PLM. This interface provides power as well as data and management connectivity between the CCT and the PLMs.

6.7.2 Connection to Backplane

The backplane connector on the leading edge (inserted first in the CCT slot) of the CCT provides power as well as data and management connectivity between pairs of CCTs and the other shelves.


Chapter 7 OTS2 Fan Tray

Each connector is labeled according to the row it supports at the front of the shelf. Up to four FastE PLMs may be installed in an ETS2 shelf (if not equipped with DS1 PLMs). Each FastE PLM provides access to the network for twelve FastE interfaces.

Figure 11-11 FastE Backplane Connections



The top connector labeled Row 2 provides access for twelve FastE interfaces to the FastE PLM in Row 2 at the front of the shelf. The next connector is Row 3, then Row 4, and finally Row 5. Refer to Figure 11-12 which indicates the association between the FastE PLMs and the FastE connectors at the rear of the shelf

Figure 11-12 ETS2 Backplane - FastE PLM to FastE Connector Association

Note that the Row 2 and Row 3 connectors (top 2 connectors) are inverted in relationship to the Row 4 and Row 5 connectors (bottom 2 connectors) just below them. Figure 11-13 below shows the port pin outs for each connector orientation on the backplane. Table 11-4 lists port pin out information for the FastE con-nectors. Turin Networks has terminated FastE cables available for purchase. Refer to the TE-2020 Order-ing Manual for details (WR-D2020-ORD-040000).

Figure 11-13 ETS2 Backplane - FastE Connector Pin Outs



Table 11-4 FastE Connector Terminations

Auto-Negotiate

The outputs of the connectors are wired for standard DTE equipment. Either DTE or DCE configured equipment may be connected to these ports as long as the auto-negotiate feature is enabled (enabled is the default setting). This is achieved during the Fast Ethernet facility provisioning (refer to the ED-FE com-mand in the TL-1 Reference Manual). The auto-negotiate feature enables or disables rate and duplex parameter negotiation.

11.3 Power Supply and ReturnThe ETS2 provides redundant (A and B) -48 Vdc power connectors to supply power to the system. Each connector has a removable plug to aid in the installation of Supply and Return wires. The A connector is labeled -48A for Supply and RTN for Return. The B connector is labeled -48B for Supply and RTN for Return. These connectors are illustrated in Figure 11-14.




The maximum, minimum, and nominal input voltages (as measured across -48 and RTN) are shown in Table 11-5 .

11.4 Frame GroundThe ETS2 provides a Frame Ground connection on the back of the shelf. The Frame Ground should be connected to the Frame or Chassis Ground for the bay.

11.5 BackplaneThe ETS2 has a three rack unit backplane that provides connectivity between the CCTs, power distribution for all of the shelf plug-ins, DS3/EC-1 interfaces through the BNC I/O backplane, DS1 interfaces through 64-pin Champ connectors, FastE interfaces through 50-pin High-Density Telco connectors, and LEI access.

11.6 LEI ConnectionThe ETS2 provides connectivity for a single LEI connection pair to provide Data and Management com-munication with the TE-2020 Main Shelf.

Table 11-5 -48V Supply and Return Specification

Power Minimum (Vdc)

Nominal (Vdc)

Maximum (Vdc)

A -42.5 -48 -56.5

B -42.5 -48 -56.5



It takes a pair of LEI cables to create a fully redundant link between the TE-2020 Shelf and a tributary shelf. There are two types of LEI cables (A and B) that make up a complete LEI connection pair. Each LEI A connector on the shelf has a female DB-15 connector which allows only anLEI A cable equipped with a male end to be connected to it. Each LEI B connector on the shelf has a male DB-15 connector which allows only a female connector on the LEI B cable to be connected to it.

11.7 ProtectionThe PLM cards should be populated from top to bottom in the shelf. ETS2 CCTs are installed in Row 1 slots 1 and 2. This provides a redundant protection mechanism for all shelf communication and traffic management. If utilized, a protect DS1 card is installed in Row 2 or Row 4, with the working DS1 PLM installed in Row 3 or Row 5. Rows not equipped with a protect card may also be utilized for unprotected FastE PLMs. If a row is left empty, a blank card must be installed to maintain proper air flow. A working and protect DS3 PLM may be installed in Row 6 slots 1 and 2 with the working card in slot one on the left. Refer to Figure 11-15 for slot identification.

Figure 11-15 Populated ETS2

11.8 Front CoverThe Front Cover is designed to cover the port level LEDs and to give the installation a neat appearance.

Chapter 12 ETS2 CCT

The ETS2 Common Control and Timing (CCT) card, illustrated in Figure 12-1, is designed for installation in the ETS2 shelf.

Figure 12-1 ETS2 CCT

12.1 ConfigurationsThe CCT supports the configurations below. Consult the TE-2020 Applications and Engineering Manual (WR-D2020-APP-040000) for configuration details.

• 1+1 Protected

12.2 Physical SpecificationsThe ETS2 CCT provides the power, synchronization, processor and SONET/SDH mapping functions for the ETS2. For each ETS2, there are two ETS2 CCTs installed for protected operation. Each CCT can be individually installed and removed with the system operational. If only one CCT is installed, the ETS2 fea-

tures do not have a redundant backup. Specifications are listed in Table 12-1 .



Part Number WR-PCCT0-006-00000


TraverseEdge 2020 Hardware Description Guide, Chapter 12: ETS2 CCT


12.3 Functional DescriptionThe ETS2 may contain two ETS2 CCT cards, two DS3/EC1 PLMs, and up to four DS1 PLMs (2 working/ 2 protect) or FastE PLMs (unprotected). The CCT performs the following functions:

• Control of the Shelf

- Power selection/conversion

- Microprocessor core

- Software storage and upgrade

- Temperature monitoring

- Reset control

- Protection switching for failure conditions• SONET Mapping

• LEI Termination and Protection• Communication with the Main Shelf

For each ETS2 there are two ETS2 CCTs installed for protected operation. Each CCT can be installed and removed with the system operational making the ETS2 fully redundant.


The CCT accepts redundant -48Vdc nominal power inputs from the rear connectors on the backplane and shares A and B for use on the system. The selected inputs are then converted to board level voltages (i.e., +1.8Vdc, +3.3Vdc, +5Vdc) and distributed to the cards and components.


The microprocessor core on the ETS2 CCT provides the necessary performance for handling the required configuration, management, routing, and real-time processing responsibilities.


Each ETS2 CCT contains five temperature sensors on the top of the board, and three temperature sensors on the bottom of the board. The system will alarm in the event that the temperature exceeds predefined lev-els.

12.3.4 Reset Control

Size 1”H x 7.25”W x 7.25”D

Weight 38.4oz.






Each ETS2 CCT contains a reset and an enable button on the front of the card. Refer to Figure 12-2. The RST (reset) button pushed by itself has no effect on the system or card. The reset button must be pushed in conjunction with the Enable button on the CCT in order to reset the ETS2 CCT.

Figure 12-2 ETS2 CCT Front Panel


The ETS2 CCT is responsible for detecting and properly switching to a redundant source for protected equipment failures within the shelf. The equipment failures can be on PLMs or on the CCTs themselves.

12.4 SONET MappingAll of the interfaces from the various PLMs are mapped to the STS-48 of the LEI in both the transmit and receive directions. The LEI traffic will be cross-connected at the TE-2020 Main Shelf.

12.5 Local Equipment Interconnect (LEI)The ETS2 CCT has protected electrical interfaces for interconnection to the TE-2020 Main Shelf. Each LEI cable is capable of transmitting two STS-48 (2.488 Gbps) bidirectional signals for up to 10 meters. The CCT is responsible for selecting the appropriate signal to use for data and management traffic as part of the protection mechanism.

12.6 Backplane ConnectorsThe backplane connector on the leading edge of the CCT (inserted first in the CCT slot) provides power as well as data and management connectivity between pairs of CCTs, PLMs and the other shelves.

18.7 SONET Framing and MappingFor a DS3 signal, the incoming electrical signal is terminated by a Line Interface Unit and the digital DS3 signal is mapped into a SONET STS-1. For an EC-1 signal, the incoming electrical signal is terminated by a Line Interface Unit and the digital STS-1 signal is framed. The STS-1 (from either the DS3 or EC-1) is mapped into an STS-12 and sent to the CCT to be mapped into an STS-48 for transmission over the LEI.



The preceding functions are performed in reverse order on transmit.

18.8 DS3 TMUXThe DS3 TMUX enables the user to configure VT mapping on any individual DS3 port. This unit can accept any DS3 with 28 DS1 framing and convert it into VT1.5 framing from either the high speed or cable entry from the interconnect backplane. If needed the user can configure two ports to work as a pair for this conversion without utilizing the interconnect backplane (i.e., signal from highspeed enters one port as an STS-1 x28 DS1s and exits its partner port as an STS-1 x 28VT1.5s). The TMUX has no limitations other than if a protect unit is available then it must be a TMUX version. A standard DS3 PLM cannot protect a DS3 TMUX PLM but the TMUX PLM can provide protection for any of the DS3 PLMs.



The DS1 Physical Layer Modules (PLM) come in either a 28 port (WR-DS128-001-00000) or an 84 port (WR-DS184-001-00000) module that can be used in the ETS2 shelf. The DS1 PLM provides the following functionality and connectivity:

• 28 or 84 electrical interfaces (depending upon the card) that are per port configurable• Ejector handles for card installation and removal

• 1 LED to indicate Card Status• 28 LEDs to indicate Facility Status

• 3 LEDs to indicate page status (84 port PLM only)• 3 LEDs to indicate page selection for ports 29-84 (84 port PLM only)

• 1 push button to select page to view (Page 1 = DS1 #1-28, Page 2 = DS1 #29-56, Page 3 = DS1# 57-84) (84 port PLM only)

• 2 Bantam jacks for test access/monitor • 1 push button to select DS1 for test access operation

• 1 push button to select test access direction • 1 LED to indicate test access direction

• Per-port mapping of STS-1• SONET framing functions

The FastE Physical Layer Module (PLM) is a 12 port plug-in module that can be used in the ETS2 shelf. The FastE x12 PLM provides the following functionality and connectivity:

• 12 x Fast Ethernet electrical interfaces that are per port configurable• Ejector handles for card installation and removal

• 1 LED to indicate Card Status• 12 LEDs to indicate Facility Status

• 12 LEDs to indicate facility Activity

• Per-port mapping of STS-1or virtual concatenation STS-1-2v• SONET framing functions

Figure 20-1 FastE x12 PLM

20.1 ConfigurationsThe FastE facilities can be set to operate in two modes. The modes are local response and pass-through. These modes define the way the facility will treat traffic flow problems.

RESPONSE

In response mode, the FastE facility will generate and respond locally to pause frames.

PASS-THRU

TraverseEdge 2020 Hardware Description Guide, Chapter 20: FastE Physical Layer Module


In the pass-through mode of operation, the FastE facility will not respond to Pause frames. The system acts like a pipe and allows other equipment to generate and respond to pause frames. The pause frames generated by other equipment will pass transparently through this system for equip-ment at the far end to respond to.

AUTO NEGOTIATION

Auto-Negotiation provides a Fast Ethernet device with the capability to detect the abilities (modes of oper-ation) supported by the device at the other end of a link segment, determine common abilities, and config-ure for joint operation. Auto-Negotiation is performed upon link startup with a special sequence of reserved link code words.

The Auto-Negotiation function is provided at the physical convergence sub-layer. Devices that support multiple modes of operation may advertise this fact using this function. The transfer of information is observable only at the media dependence interface or on the medium.

Auto-Negotiation does not perform cable tests, such as cable performance measurements

Table 20-1 Ethernet Modes Supported

LAN Support

One very important requirement from the LAN side is for 'wire speed' support. Wire speed sup-port means the device can handle the 100 Mbps traffic regardless of the frame size. The smaller the frame size the more frames need to be processed. The FastE PLM is able to handle the wire speed for all 64 bytes (the minimum Ethernet frame size).

20.2 Physical SpecificationsThe FastE x12 PLM is the one of three port cards available or the ETS2 shelf; no protection card is required for FastE. The PLM is a printed circuit board (PCB) with an attached front panel and an edge con-nector attached to the back of the board. The edge connector of the PLM unit plugs into a backplane con-nector. Alarm and status indicators are located on the front panel of the PLM. The plug-in unit also contains integral card extractors that are used to remove the board from the shelf.

The replaceable PLMs provide the external interfaces required for either customer or network access. Table 20-1 gives the Physical Specifications for the FastE x12 PLM.

20.3 Electrical ParametersThe FastE x12 PLM provides the following electrical features:

Line Side

• Complies with IEEE 802.3 10/100Base-T • Auto-MDI/MDIX crossover (automatic crossover correction for mis-wired cables)

• Reaches over 100 meters on category 5 cable [cat 5 cable calls out the impedance specs] • 16ms Differential Delay

SONET Side

• Supports bandwidth of up to 12 STS-1 SONET channels• Channels can be configured as either an STS-1 (50 Mbps) or STS-1-2v (100 Mbps)• Complies with the T1X1 specification (ANSI T1.105) of the H4 POH byte assignment for each of the VC STS-1-Nv links. (N=1-2).

NOTE: Channels supported only until the 622 Mbps of bandwidth has been utilized.

VC STS MAPPING REQUIREMENTS

In T1X1.5, two methods for concatenation are defined; contiguous and virtual concatenation. Both meth-ods provide concatenated bandwidth of X times the SPE payload capacity at the path termination. The dif-ference between these two approaches is the transport between the path terminations. Contiguous concatenation maintains the contiguous bandwidth through out the whole transport, while virtual concate-nation breaks the contiguous bandwidth into individual SPEs, transports the individual SPEs and recom-bines these SPEs to a contiguous bandwidth at the end point of the transmission. Virtual concatenation requires concatenation functionality only at the path termination equipment, while contiguous concatena-tion requires concatenation functionality at each network element.

Two types of virtual concatenations have been defined - High Order for STS-1-Xv SPE and Low Order XVTn SPE. The FastE PLM only supports HO STS-1-Xv type virtual concatenation in this release.

LEDs show the status of each individual port and the remaining 12 LEDs indicate activity on each port. The status LEDs will be green if operations are normal. If the Status LEDs become red or yellow, there is an alarm condition present on either the corresponding PLM or port. If the activity LED for a port is off, and the port is in service with no alarms, then there is no activity on that port. The alarm status colors are defined in Table 20-3 .

Table 20-3 Port Status LED Behavior


The connectorization standard for Fast Ethernet is typically RJ-45. Due to the large number of connections associated with FastE x12 PLM, it is not feasible to have RJ-45 connectorization on the shelf. The connectorization is through 50-pin mini-Telco (high-density) connectors located on the backplane. Each PLM maps to a single connector. Interconnect panels are available through Turin Networks. Refer to the TE-2020 Ordering Manual (WR-D2020-ORD-040000).







The Local Equipment Interconnect (LEI) cables are used to connect tributary shelves to the TE-2020 Main Shelf. It takes an LEI cable pair to create a fully redundant link between a tributary shelf and a TE-2020 Main Shelf.

The LEI cable pair is made up of two cables with a total of four connectors that make up a complete LEI connection. One cable has male-male DB-15 connectors and the other has female-female DB-15 connec-tors at each end. An example of an LEI cable pair is shown below in Figure 21-1.

Figure 21-1 LEI Cables

The LEI cable part numbers differentiate the different cable lengths. Refer to Table 21-1 for examples and definitions of the part numbering scheme. The maximum approved cable length is 10 meters.

nects a TE-2020 Main Shelf to a tributary shelf. Each LEI provides dual, bidirectional connections with a total bandwidth of up to 2.488 Gbps each. It carries data, management, and synchronization information between the shelves.

21.2 Functional DescriptionEach LEI cable contains two differential transmit signals and two differential receive signals. Each of the transmit differential signals is associated with a single CCT, resulting in two differential transmit signals from each shelf. Each of the receive differential signals is associated with an individual CCT from the opposite end of the LEI cable, resulting in two differential receive signals from each shelf.

Each LEI cable carries a complete bidirectional copy of all the data (transmit and receive) for a shelf. To provide protection against the failure of a single LEI, two LEIs carrying identical information are used in a single cable assembly.

The LEI interface is capable of transmitting (and receiving) the 2.488 Gbps signal up to 10 meters. Each CCT is capable of recovering the timing from the transmitted STS-48 signal and using it as a reference for the local synchronization unit.

21.3 LEI Cabling Examples

The bend radius of LEI cables should not exceed approximately 3”. Refer to Table 21-2 .

Figure 21-2 LEI Cable Bend Radius

The Figures below show five possible cabling examples for the LEI cables. Shown are:

• TE-2020 Main Shelf, One OTS2• TE-2020 Main Shelf, Two OTS2 Shelves

Auto-Negotiate

The outputs of the connectors are wired for standard DTE equipment. Either DTE or DCE configured equipment may be connected to these ports as long as the auto-negotiate feature is enabled (enabled is the default setting). This is achieved during the Fast Ethernet facility provisioning (refer to the ED-FE com-mand in the TL-1 Reference Manual). The auto-negotiate feature enables or disables rate and duplex parameter negotiation.

22.5 LEI InterfacesLEI Interface Cables are required for all applications utilizing OTS2, ETS1, or ETS2 tributary shelves. Local Equipment Interconnect ports allow connections from the TE-2020 Main Shelf to an Optical Tribu-tary Shelf or an Electrical Tributary Shelf. The tributary shelves may be remote mounted, meaning they can be installed in another rack up to 10 meters away from the TE-2020 Main Shelf. It takes a pair of LEI cables to create a fully redundant link between the TE-2020 Shelf and a tributary shelf.

The LEI connections and cables deal with Turin Networks proprietary information. The cable and back-plane connector pinouts and definitions are not provided in the user documentation.
