Hotwire TDM SDSL Termination Units

Hotwire®8777 and 8779 Termination Units are circuit card assemblies that contain

eight Time Division Multiplexer Symmetric Digital Subscriber Line (TDM SDSL)

interfaces and eight DSX-1 or G.703 interfaces. When the Hotwire 87xx TDM

SDSL Termination Unit is used in a Hotwire 8610/8810 Digital Subscriber Line

Access Multiplexer (DSLAM) chassis or 8620/8820 GranDSLAM chassis, it

transports up to 2064 Kbps signals over traditional twisted-pair telephone wiring.

A Hotwire TDM SDSL Termination Unit can be installed, removed, and replaced

from a DSLAM chassis without disrupting service to the other cards in the chassis.

HANDLING PRECAUTIONS FOR

STATIC-SENSITIVE DEVICES

This product is designed to protect sensitive components from damage

due to electrostatic discharge (ESD) during normal operation. When

performing installation procedures, however, take proper static control

precautions to prevent damage to equipment. If you are not sure of the

proper static control precautions, contact your nearest sales or service

representative.

Procedure

To install the unit:

1. Determine in which slot the unit will be installed. Verify that cards in adjacent

slots have been fastened.

2. Remove the filler plate from the installation slot and store for possible later

use.

3. Insert the unit:

—ForaHotwire 8610 DSLAM or 8620 GranDSLAM chassis – Hold the

–

Hold the

unit vertically, with the component side facing right, and insert it into the

top and bottom card guides.

4. Slide the unit into the slot until the power and network connectors seat firmly in

the mating connectors on the backplane.

CAUTION:

Do not force the unit into the slot. This could damage the backplane

connectors. If the card does not seat properly, remove the card and

reinstall it. If it still does not seat properly, call your service

representative.

The termination unit performs a power-on self-test. All of the LEDs turn ON

and OFF briefly. When the self-test is completed successfully, the SYSTEM

OK LED begins to pulse.

5. If the LED is not pulsing, refer to

Monitoring and Troubleshooting

in the User’s

Guide.

6. Secure the unit by fastening the screws at each end of the faceplate.

Connecting to the DTE

Connection to the eight DTE ports of the Hotwire 87xx TDM SDSL Termination

Unit is through the 50-pin interface connector on its faceplate. Refer to

Connector

Pin Assignments

in the User’s Guide.

Procedure

To connect the Hotwire 87xx TDM SDSL Termination Unit to your DTE:

1. Insert and fasten the hex-head jackscrew included with the unit into the top nut

(the nut nearest the LEDs) on the 50-position connector on the faceplate.

2. Connect the 50-position connector of the cable to the connector on the

faceplate. Align one end of the cable connector with the card connector, then

push on the cable connector until it seats.

3. Fasten the captive screw in the top of the cable connector to the hex-head

jackscrew.

4. Secure the bottom of the cable connector to the unit using a cable tie.

5. Feed the cable through the Cable Guide if it is installed. When all cables are

installed, anchor them with cable ties to the rack, DSLAM, or Cable Guide.

6. Connect the terminating connectors to your DTE.

Connecting to an MDF

You can connect the Hotwire DSLAM chassis containing the Hotwire 87xx TDM

SDSL Termination Unit to an MDF or other demarcation point. Do not connect it to

a POTS splitter.

Procedure

To connect the Hotwire chassis containing the unit to an MDF:

1. Plug the Telco 50-pin cable into the appropriate line port on the chassis:

—ForaHotwire 8610/8620 DSLAM chassis – Line connectors are

numbered 1–3 on the back of the chassis. After installing the connector,

insert a cable tie through the tie mount to hold the cable in place.

—ForaHotwire 8810/8820 DSLAM chassis

–

Line connectors are

numbered 1–18 on the back of the chassis.

2. Make sure the other end of the cable is connected to the appropriate MDF or

demarcation point.

Refer to

Connector Pin Assignments

in the User’s Guide for pinouts.

NOTE:

If connecting the Telco 25-pair, 50-pin cable to an MDF, a converter may be

necessary for terminating the other end of the cable on a punchdown block

before cross-connecting to an MDF.

Configuring Cross-Connections

The Hotwire cross-connect system allows you to connect the DSX-1 or G.703

ports to the DSL ports in a variety of ways:



DS1 Bypass mode – The entire DSX-1 or G.703 interface is connected to the

DSL interface.



DS1 Cross-Connect mode – The entire DSX-1 or G.703 interface is

connected to the DSL interface through cross-connect circuitry. Ports can be

switched through software.



DS0 Cross-Connect mode – Any time slot of any DSX-1 or G.703 interface

can be connected to any time slot of any DSL interface. Time slots can be

individually allocated for voice or data.

Configuration of the cross-connections consists of the following steps:

❑Determine how the ports will be connected and configured.

❑On the Network Interface Options screen, enable if necessary the DSL ports

that will be in the cross-connection. The ports are enabled by default.

❑On the DSX-1 or G.703 Interface Options screen, enable the DSX-1 or G.703

ports that will be in the cross-connection. For G.703, specify whether Time

Slot 16 is used for signaling (voice mode).

❑On the System Clock screen, configure the system clock.

❑On the Cross-Connect Mode screen:

— Define all DS1 Bypass ports

— Define all DS1 Cross-Connect ports

— Define all DS0 Cross-Connect ports

❑On the Assign Time Slots screen, configure the DS0 cross-connections.

IMPORTANT:

All DSL time slots are available for cross-connect regardless of DSL line

rate, but all time slots are only available for data transport if the DSL line

rate is the full rate (1552 for DSX-1 or 2064 for G.703). Only configure

time slots that will be used.
