Using Terminal and Switchpack
Modes
3
Choosing an Interface Mode
You can make configuration changes either through the system terminal menus
(Terminal Mode) or by manually changing switches and jumpers on the board
(Switchpack Mode). Terminal Mode is the default setting.
In Terminal Mode:
You change configuration parameters by selecting menu options that appear
on a VT100-compatible terminal attached to the front panel of the termination
unit.
The unit is preconfigured at the factory for CP (customer premises) operation.
If you change the line build-out, you still need to move jumpers on the board
hardware.
In Switchpack Mode:
All configuration parameters are taken from the current setting of the
switchpacks and jumpers.
You must ensure that the switchpacks and jumpers are set as desired. (They
are not preconfigured at the factory.)
You can still display information about the unit from the terminal.
Any changes you had made in Terminal Mode are lost when you change to
Switchpack Mode.
Connecting to a System Terminal
An optional system maintenance terminal may be attached to your Model 7925
standalone termination unit through the modular jack on the front panel. You may
have terminals attached to both endpoints (HTU-C and HTU-R).
The system terminal must be a VT100-compatible terminal or emulation software
on a PC.
