Hotwire 8799 TDM SHDSL Line Card
The Hotwire®8799 Line Card is a circuit card assembly that contains eight Time
Division Multiplexer Symmetric High-bit-rate Digital Subscriber Line (TDM SHDSL)
ports and a G.703 interface. When the card is used in a Hotwire 8610/8620 or
8810/8820 Digital Subscriber Line Access Multiplexer (DSLAM) chassis, it
transports up to 2048 Kbps signals over traditional twisted-pair telephone wiring.
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.

SHDSL Line Card vertically, with the component side facing right, and
insert it into the top and bottom card guides.
4. Slide the card into the slot until the power and network connectors seat firmly
in the mating connectors on the backplane.
CAUTION:
Do not force the card 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 card 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 Hotwire

Connecting to the DTE
Connection to the four ports of the Hotwire 8799 TDM SHDSL Line Card is
through the 50-pin interface connector on its faceplate. Refer to
Connector Pin
Assignments
in the Hotwire 8799 TDM SHDSL Line Card, with G.703 Interface,
User’s Guide
.
Procedure
To connect the Hotwire 8799 TDM SHDSL Line Card to your DTE:
1. Connect the 50-position connector of the cable to the connector on the
faceplate of the card. 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.
2. Feed the cable through the Cable Guide if it is in use. 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.
Installing the Ferrite Chokes
Two ferrite chokes (supplied) must be installed on the DTE cable to ensure
compliance with EN 55022.
Procedure
To install the ferrite chokes on the DTE cable:
1. Open a ferrite choke and place it around the cable as close to the Hotwire
8799 TDM SHDSL Line Card 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. Install the second ferrite choke adjacent to the first.
4. If necessary to prevent the ferrite chokes from slipping down the cable, install
a tie wrap behind the second ferrite choke.

Connecting to an MDF
You can connect the Hotwire DSLAM chassis containing the Hotwire 8799 TDM
SHDSL Line Card to an MDF or other demarcation point. Do not connect it to a
POTS splitter.
Procedure
To connect the Hotwire DSLAM chassis containing the Hotwire 8799 TDM SHDSL
Line Card to an MDF:
1. Plug the Telco 50-pin cable into the appropriate LINE port on the chassis.
2. Replace the longer Telco cable captive screw with a shorter connector captive
screw, which is provided with the Hotwire DSLAM chassis.
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
Connector Pin Assignments in the Hotwire 8799 TDM SHDSL Line
Card, with G.703 Interface, 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.
