Troubleshooting the Administration Terminal
Note: If the CMCC system LED has stopped flashing and the Administration
Terminal has no display, it is not properly connected to the CMCC. If
the CMCC system LED stops flashing but the Administration Terminal
button LCDs continue to flash, the Administration Terminal is not
connected to one of the first five TCM ports on the CMCC. In either
case, check the main distribution frame wiring and correct any problem.
1. Check that the time and date appear on the display.
2. Check the display. If the display is unreadable, ensure that the display
contrast adjustment (
ƒ•‡
) is adequate.
3. Check that power is on in the system.
4. Check that the Administration Terminal is connected to the correct port.
5. Check the 50-pin connectors at the system and make sure they are
plugged in properly.
6. Check the 25-pair TCM cables at the distribution frame to make sure
they are connected to the right ports.
7. Check the telephone wiring connections at the distribution frame to
make sure the connections have been made on the appropriate
connectors (see “Installing the hardware” chapter).
