UDS1-BD (UDS1 Interface Circuit Pack)
Table 533. TEST #141 Yellow Alarm Inquiry Test — Continued
Error Test
Code Result
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:
If the UDS1 connects to a line-side terminating device such as a PRI terminal
adapter:
555-233-119
Description/ Recommendation
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.
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.
