MG-DS1 (DS1 Interface Media Module)
Maintenance of the Avaya G350 Media Gateway 201
June 2004
2 FAIL The MG-DS1 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 MG-DS1 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
Contact T1 Network Service to diagnose the remote DS1
endpoint.
3
Check the physical connectivity of the DS1 Interface Media
Modules and cable.
4
Replace the local MG-DS1 Interface Media Module and
repeat the test.
If the MG-DS1 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
Contact the vendor of the line-side terminating device to
diagnose the equipment.
4
Check the physical connection of the MG-DS1 Interface
Media Module to the terminating device. Check premise
distribution system (or intra-premise wiring) for physical
connection failures.
5
Replace the local MG-DS1 Interface Media Module and
repeat the test.
