UDS1-BD (UDS1 Interface Circuit Pack)
Issue 1 June 2005 2427
FAIL The UDS1 interface circuit pack detected a Yellow alarm sent by the
remote DS1 endpoint. An out-of-frame condition occurred at the DS1
endpoint.
If the UDS1 connects to a T1 network facility or to another switch, do the
following:
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 or a technician at the far-end switch to
diagnose the remote DS1 endpoint.
3. Check the physical connectivity of the UDS1 packs and of the cable.
4. Replace the local UDS1 interface circuit pack, and repeat the test.
If the UDS1 connects to a line-side terminating device (for example, a PRI
terminal adapter), do the following:
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, and check the premise distribution system (or
the intra-premise wiring) for physical connection failures.
5. Replace the local UDS1 interface circuit pack and repeat the test.
