UDS1-BD (UDS1 Interface Circuit Pack)
Issue 4 May 2002 10-1887 555-233-123
2 FAIL The UDS1 interface circuit pack 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 UDS1 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 circuit
packs and cable.
4. Replace the local UDS1 Interface circuit pack and repeat the
test.
If the UDS1 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 UDS1 Interface circuit
pack to the terminating device. Check premise distribution
system (or intra-premise wiring) for physical connection
failures.
5. Replace the local UDS1 Interface circuit pack and repeat the
test.
