MG-DS1 (DS1 Interface Media Module)
Issue 1 June 2005 1623
2 FAIL The MM710 interface Media Module is reporting a Yellow F5 fault alarm.
There is a fault in the User-Network interface from the user (PBX) to the
network. An out-of-frame condition occurs on the remote DS1 endpoint.
If the MM710 connects to a T1 network facility:
1. Verify that both endpoints of the DS1 link are administered using the
same signaling mode, framing mode, and line coding.
2. Check the physical connectivity of the DS1 Interface Media Modules
and cable.
3. Replace the local MM710 Interface Media Module and repeat the
test.
4. Contact T1 Network Service to diagnose the remote DS1 endpoint.
If the MM710 connects to a line-side terminating device such as a PRI
terminal adapter:
1. Verify that the switch DS1 and the line-side terminating device are
administered using the same signaling mode, framing mode, and line
coding.
2. Investigate the maintenance status of the line-side terminating
device. Refer to the 'Line-Side Terminating Device Operating Manual'
for information.
3. Check the physical connection of the MM710 Interface Media Module
to the terminating device. Check premise distribution system (or
intra-premise wiring) for physical connection failures.
4. Replace the local MM710 Interface Media Module and repeat the
test.
5. Contact the vendor of the line-side terminating device to diagnose the
equipment.
PASS Neither a Yellow alarm nor a Remote Multiframe Alarm nor a F5 state
alarm is being received from the remote DS1 endpoint.
