Connecting Power to the Unit
If your package includes a power transformer:
1. Plug the power cable into an AC outlet having a nominal voltage rating between
100–240 VAC.
2. Connect the power cable to the transformer.
3. Connect the output cable of the transformer to the connector marked POWER on
the rear panel.
If your package includes a direct-connection DC power cable:
Connect the unit to an external +24 or –48 VDC SELV (Safety Extra Low Voltage) power
source as described in the following section.

3
Connecting the Unit to an Optional External +24 or –48 VDC Power
Source
Using the DC power cable, the unit is capable of operating on a +24 VDC or –48 VDC
SELV power supply.
Procedure
To use the DC power cable for +24 VDC:
1. Connect the green wire to a suitable ground.
2. Connect the orange wire to the +24 VDC source.
3. Connect the white wire to the return.
4. Cut the black, red, and blue wires off at the outer insulation.
5. Plug the power connector into the unit.
Procedure
To use the DC power cable for –48 VDC:
1. Connect the green wire to a suitable ground.
2. Connect the orange wire to the –48 VDC source.
3. Connect the black wire to the return.
4. Cut the red, white, and blue wires off at the outer insulation.
5. Plug the power connector into the unit.

Connecting to the Network
Procedure
To connect your unit to the network:
1. Connect one end of the supplied 8-position modular-to-8-position modular network
cable into the rear panel DSL jack.
2. Connect the other end to your DSL network interface.
NOTE:
Do
not
use a flat VF network cable as this may severely degrade the
performance of the unit. Use only Cat 5 twisted-pair network cable.
Connecting to a DTE
See
Connectors, Cables, and Pin Assignments
in the User’s Guide for specifications of
the connectors and cables.
Ferrite Choke (Model 7995)
Procedure
To install the ferrite choke onto the DTE
cable or V.35 adapter cable assembly:
1. Open the ferrite choke and place it
around the cable as close to the
cable connector as possible.
2. Close the two halves around the cable and snap the choke shut, pressing down on
the plastic latch to secure it in place.
3. Add a tie wrap (not included) to prevent the ferrite choke from slipping down the
cable.
All ferrite chokes that are supplied must be installed following these instructions to
ensure compliance with EMI regulations.
Model DTE Connection
7995 The synchronous interface is a25-pin EIA-530-A interface. Depending on the
cable used, the interface can be adapted to an X.21, RS-449, or V.35
interface.
7996 The G.703 interface is either two BNC connectors (Transmit and Receive) for
a 75-ohm unbalanced interface or an 8-position, unkeyed modular connector
for a 120-ohm balanced interface.

Connecting to a System Terminal
An optional system maintenance terminal may be attached to your Hotwire 799x
endpoint through the modular jack on the rear panel. The system maintenance terminal
allows you to view the status of the unit and change configuration options. The terminal
must be a VT100-compatible terminal or a PC running terminal emulation software.
Procedure
To connect your unit to a system terminal:
1. Connect the 9-pin end of the supplied terminal cable into a COM port on your PC.
2. Plug the other end into the modular jack on the rear panel.
3. Set the communication parameters on your PC or terminal to:
—9600 baud
—8 bit characters
—no parity
—1 stop bit
—no flow control
4. Press Enter from your terminal or PC to activate the Main Menu for the attached
unit.
The system runs diagnostics and status checks. After a few moments, the Main
Menu or Logon screen appears on your terminal.
