FAIL Minor alarms are often accompanied by slip and misframe alarms against the
board. Trunk alarms and hardware error logs may occur on the associated
trunks.
If the UDS1 connects to a T1 network facility or to another switch, do the
following:
1. The performance of the DS1 link between the UDS1 interface circuit pack
and the remote DS1 endpoint is poor. Enter the list measurement ds1-log
UUCSS command to read the error seconds measurement.
2. Verify that both endpoints of the DS1 link are administered using the same
signaling mode, framing mode, and line coding .
3. Contact T1 Network Service or the technician at the remote switch to
diagnose the equipment.
4. Check the physic al connectivity of the UDS1 interfac e circuit packs and the
cable.
5. Replace the local UDS1 interface circuit pack, and repeat the test.
FAIL
(cont’d.)
If the UDS1 connects to a line-side terminating device (for example, a PRI
terminal adapter), do the following:
1. The performance of the DS1 link between the UDS1 interface circuit pack
and the line-side term inating device is very p oor. Enter the list
measurement ds1-log UUCSS command to read the error seconds
measurement.
2. Verify that the switch DS1 and the line-side terminating device are
administered using the same signaling mode, framin g mode, and line
coding.
3. Investigate the maintenance status of the line-side terminating device.
Obtain the error seconds measurement on the terminating device (if
possible). Refer to the ’Line-Side Terminating Device Operating Manual’ for
information.
4. Contact the vendor of the line-side terminating device to diagnose the
equipment.
5. Check the physic al connection of the UDS1 interfac e circuit pack to the
terminating device, and check the premise di strib ution system (or the
intra-premise wiring) for p hysical connection fa ilures.
6. Replace the local UDS1 interface circuit pack and repeat the test.
