T-1 Alarm Programming
Description
The T-1 Trunk card and the system software provide tools to help detect and isolate problems
which may occur with the T-1 circuit. There are six LEDs mounted on the outside edge of the
T-1 Trunk card which either light or flash to indicate a variety of conditions on the T-1 circuit.
The Central Office Maintenance Center can send a command to place the CSU into Line Loop
Back mode. If there is no CSU, the T-1 Trunk card responds to the Line Loop Back command.
