3-17925-A2-GB20-30PRELIMINARY DRAFTJune 1997Using Terminal and SwitchpackModes3Choosing an Interface ModeYou 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 appearon a VT100-compatible terminal attached to the front panel of the terminationunit. 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 boardhardware.In Switchpack Mode: All configuration parameters are taken from the current setting of theswitchpacks and jumpers. You must ensure that the switchpacks and jumpers are set as desired. (Theyare 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 toSwitchpack Mode.Connecting to a System TerminalAn optional system maintenance terminal may be attached to your Model 7925standalone termination unit through the modular jack on the front panel. You mayhave terminals attached to both endpoints (HTU-C and HTU-R).The system terminal must be a VT100-compatible terminal or emulation softwareon a PC.
