Hotwire 8784 TDM SDSL Termination Unit
The Hotwirer8784 Termination Unit is a circuit card assembly that contains two
Time Division Multiplexer Symmetric Digital Subscriber Line (TDM SDSL) ports
and a DSX-1 interface. When the Hotwire 8784 TDM SDSL Termination Unit is
used in a Hotwire 8600 or 8800 Series Digital Subscriber Line Access Multiplexer
(DSLAM) chassis, it transports up to 1544 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.

Installing TDM SDSL Cards
A Hotwire 8784 TDM SDSL Termination Unit can be installed, removed, and
replaced without disrupting service to the other cards in the chassis.
"Procedure
To install the unit:
1. Determine in which slot the unit will be installed. Verify that cards in adjacent
slots have been fastened.
2. Remove the filler plate from the installation slot and store for possible later
use.
3. Insert the unit:
—For a Hotwire 8600 Series DSLAM chassis – Hold the unit horizontally,
with the component side facing up, and insert it into the left and right card
guides.
—For a Hotwire 8800 Series DSLAM chassis –Hold the unit vertically,
with the component side facing right, and insert it into the top and bottom
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 termination 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 two ports of the Hotwire 8784 TDM SDSL Termination Unit is
through the 50-pin interface connector on its faceplate. Refer to Connector Pin
Assignments in the User’s Guide.
"Procedure
To connect the Hotwire 8784 Termination Unit to your DTE:
1. Connect the 50-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.
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 two terminating connectors to your DTE or DTEs.
Connecting to an MDF
You can connect the Hotwire DSLAM chassis containing the Hotwire 8784 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 chassis containing the unit 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 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.
