Hotwire TDM SDSL Termination Units

Hotwirer8775 and 8785 TDM SDSL Termination Units are circuit card assemblies

comprising four Time Division Multiplexer Symmetric Digital Subscriber Line

(TDM SDSL) ports and four synchronous ports. When the Hotwire 87xx TDM SDSL

Termination Unit is used in a Hotwire 8600 or 8800 Series Digital Subscriber Line

Access Multiplexer (DSLAM), it transports up to 2048 kbps signals over traditional

twisted-pair telephone wiring.

Installation Overview

Installation and configuration of the Hotwire 87xx TDM SDSL Termination Unit

consists of:

HInstalling the unit in the DSLAM.

HConnecting to the Data Terminal Equipment (DTE).

HConnecting to a Main Distribution Frame (MDF).

HProviding initial unit identity information or changing existing identity information.

HConfiguring the unit using the Configuration Edit menus.

Before you install the unit, read the Important Safety Instructions in the appropriate

DSLAM manual.

Installing TDM SDSL Cards

A Hotwire TDM SDSL Termination Unit can be installed, removed, and replaced without

disrupting service to other cards in the chassis.

!HANDLING PRECAUTIONS FOR STATIC-SENSITIVEDEVICES

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 using the screws at each end of their front panels.

2. Remove the filler plate from the installation slot.

3. Insert the unit into the DSLAM:

—For a Hotwire 8600 Series DSLAM – Hold the unit horizontally, with the

component side facing up, and insert it into the left and right 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 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 Messages 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 four ports of the unit is through the 100-pin connector on its

faceplate. Use one of the DTE cables listed under Cables You Need on page 3.

"Procedure

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

1. Connect the 100-position connector of the cable to the connector on the faceplate

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

on the cable connector until it seats.

The end of the cable connector has two release buttons. To remove the connector,

press the release buttons simultaneously and pull the connector away from the

card.

2. 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.

3. Connect the four terminating connectors to your DTE.

Connecting to an MDF

You can connect the Hotwire DSLAM 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 DSLAM containing the unit to an MDF:

1. Plug the 50-position Telco cable into the appropriate connector on the DSLAM

using the following table.

2. If necessary to attach the cable connector firmly in place, replace the longer Telco

cable captive screw with a shorter one. Fasten the connector.

3. Insert a cable tie (provided with Hotwire DSLAM) through the tie mount to hold the

50-position Telco connector in place.

4. Make sure the other end is connected to the appropriate MDF or demarcation

point.

NOTE:

If connecting the Telco 25-pair, 50-position 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.

Ferrite Choke (Installation in Hotwire 8820 GranDSLAM Only)

CAUTION:

All ferrite chokes that are supplied must be installed following these

instructions to ensure compliance with FCC Part 15, VCCI, and CISPR22

rules.

"Procedure

A ferrite choke is included with all Hotwire 8775 and 8785 TDM SDSL Termination

Units. The ferrite choke is only required if you install the termination unit in a Hotwire

8820 GranDSLAM; otherwise, it can be discarded.

To install the ferrite choke onto the 50-pin DSL cable:

1. Open the ferrite choke and place it around the cable as close to the Hotwire 8820

GranDSLAM as possible.

2. Close the two halves around the cable and snap the choke shut, pressing down on

the plastic latch to secure it.

3. Add a tie wrap if necessary to prevent the ferrite choke from slipping down the

cable.

Entering Identity Information

After accessing your unit for the first time, use the Change Identity screen to determine

SNMP administrative system information that will be displayed on the Identity screen of

the Status branch. To access the Card Identity screen, follow this menu selection

sequence:

Main Menu →Control →Change Identity

Configuring the Unit

Configuration option settings determine how the unit operates. Use the Configuration

menu branch to display or change configuration option settings.

The unit is shipped with factory settings in the Default Factory Configuration area. If the

factory default settings do not support your network’s configuration, customize the

configuration options for your application.

A DSLAM-to-DSLAM configuration requires that the unit at one end of the link be set to

NTU mode. DSLAM-mounted Hotwire termination units default to LTU mode.

Accessing and Displaying Configuration Options

To display the configuration options, you must first load a configuration option set into

the edit area.

To load a configuration option set into the configuration edit area, follow this menu

selection sequence:

Main Menu →Configuration (Load Configuration From)
