Hotwire8775 E1 MSDSL Termination Unit

The Hotwire 8775 Termination Unit is a circuit card assembly (CCA) that contains

four E1 Multirate Symmetric Digital Subscriber Line (MSDSL) ports. When the

8775 Termination Unit is used in a Hotwire 8600 or 8800 Digital Subscriber Line

Access Multiplexer (DSLAM) chassis, it transports 2048 kbps signals over

traditional twisted-pair telephone wiring.

!HANDLING PRECAUTIONS FOR

STATIC-SENSITIVE DEVICES

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.

NOTE:

When installing the 8775 Termination Unit, you need to remove the filler plate

before proceeding.

Do not discard unused filler plates. Each slot in the chassis must contain a

circuit card or a filler plate. Store all unused filler plates in a safe place. You

may need to use the filler plates to cover open slots in the chassis at a later

time.

4. Slide the 8775 Termination Unit into the slot until the power and network

connectors seat firmly in the mating connectors on the backplane.

CAUTION:

Do not force the 8775 Termination Unit into the slot. If it does not seat

properly, remove the card and reinstall it. If it still does not seat

properly, call your service representative.

The 8775 Termination Unit performs a power-up self-test. All of the LEDs turn

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

SYSTEM OK LED will turn ON. Make sure the SYSTEM OK indicator on the

8775 Termination Unit faceplate is ON.

5. If the LED is not ON, refer to Chapter 6,

Messages and Troubleshooting

the User’s Guide.

6. Secure the 8775 Termination Unit by fastening the screws at each end of the

faceplate.

NOTE:

The 8775 Termination Unit may be replaced without system disruption (i.e.,

you can remove and reinstall a card without powering down the Hotwire

DSLAM chassis and disrupting service to the other cards). To remove an

8775 Termination Unit from the Hotwire DSLAM chassis, unfasten the screws

on both ends of the faceplate. Then push the ejector handles outward and

slide the card out.

Ensure that adjacent cards are fastened before removing a card.

When swapping the old 8775 Termination Unit with a new 8775 Termination

Unit, note that the 8600 DSLAM retains the Media Access Control (MAC)

address, also referred to as the physical address. This means that the new

8775 Termination Unit will have the same MAC address as the old one.

Connecting to the DTE Equipment

Connection to the four ports of the 8775 Termination Unit is through the 100-pin

EIA-530 interface connector on its faceplate. Use one of the DTE cables listed

under

Cables You Need

on page 3.

Procedure

To connect the Hotwire 8775 Termination Unit to your DTE equipment:

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

faceplate of the 8775 Termination 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 a release button. To remove the

connector, press the release button and pull the connector away from the

card.

3. Insert a cable tie (provided with Hotwire DSLAM chassis) through the tie

mount to hold the Telco 50-pin connector in place. If more than one Telco

cable is being connected, span the two or three connectors.

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

point.

Refer to Appendix D,

Cables and Pin Assignments

, in the User’s Guide for

pinouts.

NOTE:

If you are 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.
