Hotwire TDM SDSL Termination Units

Hotwirer 8775 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:

H Installing the unit in the DSLAM. H Connecting to the Data Terminal Equipment (DTE). H Connecting to a Main Distribution Frame (MDF). H Providing initial unit identity information or changing existing identity information. H Configuring the unit using the Configuration Edit menus.

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

Planning the Installation

Review the following list to help plan for the installation.

Obtain the applicable cables; refer to Cables You Need.

Make sure the Hotwire DSLAM is installed and power is supplied to the chassis.

After the unit is installed, there are configuration procedures that must be performed before you can begin to use it. Refer to the User’s Guide if you require detailed configuration procedures.

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-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 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.

Page 6

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.
