Connecting Power to the Unit
If your package includes a power pack: Plug the power pack into an ac outlet
having a nominal voltage rating between 100–240 Vac. Connect the output cable
of the power pack to the connector marked POWER on the rear panel.
If your package includes a direct-connection+24 Vdc power cable: Connect the
unit to an external +24 Vdc power source as described in Connecting the Unit to
an Optional External +24 Vdc Power Source
.
If you will use a –48 Vdc power supply: Connect the unit to an external –48 Vdc
power source as described in the documentation shipped with the power supply
and power cable.
Connecting the Unit to an Optional External +24 Vdc Power Source
Use the following procedures only if you want to use the +24 Vdc power
cable.
Using the dc power cable, the Hotwire 7975 Standalone Termination Unit is
capable of operating on a +24 Vdc power supply.
Procedure
To use the dc power cable:
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 Termination Unit.

Connecting to the Network
Procedure
To connect your unit to the network:
1. Connect one end of the supplied network cable into the rear panel DSL jack.
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 termination unit. Use only Cat 5 twisted-pair network
cable.
Connecting to the DTE
The Hotwire 7975 Standalone Termination Unit connects to Data Terminal
Equipment (DTE) using a 25-pin EIA-530-A interface. Depending on the cable
used, the interface can be adapted to an X.21, RS449, or V.35 interface. See the
User’s Guide for more information.
Ferrite Choke
Procedure
To install the ferrite choke onto the DTE cable:
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) as shown to prevent the ferrite choke from
slipping down the cable.

Connecting to a System Terminal
An optional system maintenance terminal may be attached to your Hotwire
7975 Standalone Termination Unit 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 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
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.
Entering Identity Information
After accessing your unit for the first time, use the Change Identity screen to
determine SNMP administrative system information that will be displayed on the
Identity screen of the Status branch. To access the Card Identity screen, follow
this menu selection sequence:
Main Menu → Control → Change Identity

Network Configuration
The following figure shows several configurations including a network application
using a 4-port Hotwire 8775 M/SDSL Termination Unit in a central office (CO). In
this configuration, a frame relay switch and a router are connected, through the
termination unit, to partner units supporting a host or router, and frame relay
encapsulated or unframed data. The figure also shows a possible
standalone-to-standalone configuration.

Sample M/SDSL Configurations
In a DSLAM-to-standalone configuration:
The devices synchronize without altering factory defaults, since the CO unit
defaults to LTU mode, and the CP unit defaults to NTU mode.
In a standalone-to-standalone configuration:
One unit must be changed to run in LTU mode, since standalone units have
a factory default setting of NTU mode.
In both cases the clocking source may have to be altered depending on network
requirements.

Choosing a Configuration Mode
You can make configuration changes either through a VT100-compatible terminal
and the unit’s Configuration menus or by manually changing switches on the
board. The unit comes configured to allow settings to be made through the
Configuration menus.
Configuring the Unit Using the Configuration Menus
You can use the Configuration menu branch of the unit to display or change
configuration option settings.
The Hotwire 7975 Standalone Termination Unit has two sets of configuration
option settings.
The Current Configuration (the 7975 Standalone Termination Unit’s active set
of configuration options)
The Default Factory Configuration (a read-only configuration area containing
the factory default configuration options)
If the factory default settings do not support your network’s configuration, you
can customize the configuration options for your application. You must first load a
configuration into the edit area.
To load a configuration option set into the configuration edit area, follow this
menu selection sequence:
Main Menu → Configuration (Load Configuration From)
Make a selection by placing the cursor at your choice and pressing Enter.
If you select . . . Then . . .

through the DTE interchange circuits as specified by the V.54 standard.
ElasticStore
Possible Settings: Disable, Enable
Default Setting: Enable
Used to enable or disable a first in first out (FIFO) buffer circuit for the incoming external

Configuring the Unit Using the Internal Switches
If desired, use internal Switchpacks S1 and S2 to manually configure the unit.
!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.
Procedure
To configure the unit using internal Switchpacks S1 and S2:
1. Power down the unit and disconnect the power supply.
2. Remove the enclosure cover:
— Insert a small, flat screwdriver blade into the slots on one side of the
cover and push to free the inner latches
— Lift off the cover to expose the circuit board
3. Locate Switchpack S1.
4. Set switch 1 on Switchpack S1 to ON to enable Switchpacks 1 and 2.
5. After you enable the switchpacks, you must set the switches to your desired
configuration.
6. Replace and secure the cover.
7. Power up the board to reset and enable the new configuration.
