Hotwire TDM SDSL Termination Units
Hotwire® 8777 and 8779 Termination Units are circuit card assemblies that contain
eight Time Division Multiplexer Symmetric Digital Subscriber Line (TDM SDSL)
interfaces and eight DSX-1 or G.703 interfaces. When the Hotwire 87xx TDM
SDSL Termination Unit is used in a Hotwire 8610/8810 Digital Subscriber Line
Access Multiplexer (DSLAM) chassis or 8620/8820 GranDSLAM chassis, it
transports up to 2064 Kbps signals over traditional twisted-pair telephone wiring.

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.

Connecting to an MDF
You can connect the Hotwire DSLAM chassis 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 chassis containing the unit to an MDF:
1. Plug the Telco 50-pin cable into the appropriate line port on the chassis:
—For a Hotwire 8610/8620 DSLAM chassis – Line connectors are
numbered 1–3 on the back of the chassis. After installing the connector,
insert a cable tie through the tie mount to hold the cable in place.
—For a Hotwire 8810/8820 DSLAM chassis
numbered 1–18 on the back of the chassis.
2. Make sure the other end of the cable is connected to the appropriate MDF or
demarcation point.
Refer to
NOTE:
Connector Pin Assignments
–
Line connectors are
in the User’s Guide for pinouts.
If 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.

Configuring Cross-Connections
The Hotwire cross-connect system allows you to connect the DSX-1 or G.703
ports to the DSL ports in a variety of ways:
DS1 Bypass mode – The entire DSX-1 or G.703 interface is connected to the
DSL interface.
DS1 Cross-Connect mode – The entire DSX-1 or G.703 interface is
connected to the DSL interface through cross-connect circuitry. Ports can be
switched through software.
DS0 Cross-Connect mode – Any time slot of any DSX-1 or G.703 interface
can be connected to any time slot of any DSL interface. Time slots can be
individually allocated for voice or data.
Configuration of the cross-connections consists of the following steps:
❑ Determine how the ports will be connected and configured.
❑ On the Network Interface Options screen, enable if necessary the DSL ports
that will be in the cross-connection. The ports are enabled by default.
❑ On the DSX-1 or G.703 Interface Options screen, enable the DSX-1 or G.703
ports that will be in the cross-connection. For G.703, specify whether Time
Slot 16 is used for signaling (voice mode).
❑ On the System Clock screen, configure the system clock.
❑ On the Cross-Connect Mode screen:
— Define all DS1 Bypass ports
— Define all DS1 Cross-Connect ports
— Define all DS0 Cross-Connect ports
❑ On the Assign Time Slots screen, configure the DS0 cross-connections.
IMPORTANT:
All DSL time slots are available for cross-connect regardless of DSL line
rate, but all time slots are only available for data transport if the DSL line
rate is the full rate (1552 for DSX-1 or 2064 for G.703). Only configure
time slots that will be used.
