FAIL The UDS1 interface circuit p ack 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 cab le.
4. Replace the local UDS1 interface circuit pack, and rep eat 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 mod e, 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 d i ag nose the
equipment.
4. Check the p hysical connecti on of the UDS1 interface circ uit pack to the
terminating device, and check the premise di strib ution system (or the
intra-premise wiring) for p hysical connec tion failures.
5. Replace the local UDS1 interface circuit pack and rep eat the test.
