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.

An 8775 Termination Unit can be installed, removed, and replaced from a Hotwire
DSLAM chassis without disrupting service to the other cards in the chassis.
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.

Procedure
To install an 8775 Termination Unit:
1. Determine in which slot the 8775 Termination Unit will be installed. Verify that
cards in adjacent slots have been fastened.
2. Remove the filler plate from the installation slot.
3. Insert the 8775 Termination Unit:
— For a Hotwire 8600 DSLAM chassis – hold the 8775 Termination Unit
horizontally with component side facing up and insert it into the left and
right card guides.

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 , in
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.

Cable Management
The optional Cable Guide (see Technical Specifications on page 2 for its part
number) connects to the front of the Hotwire 8800 DSLAM and provides strain
relief and control of the DTE cables. Install the Cable Guide before installing the
cables.

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.
