UDS1-BD (UDS1 Interface Circuit Pack)
Issue 1 May 2002
8-1773
555-233-143
1 to 17
FAIL
The test failed because the UDS1 interface circuit pack detected errors in the
received framing bits pattern. The error code equals the number of misframes
detected by the UDS1 interface circuit pack since the last misframe alarm
inquiry test. Major bit and minor bit error rate (error types 2561 and 2817)
error logs often accompany misframe alarms. Clearing the cause of these
error logs may clear the misframes which are occurring.
If the UDS1 connects to a T1 network facility or to another switch, do the
following:
1. Retry the command at 1-minute intervals up to 5 times.
2. If the DS1 interface circuit pack is a TN464C, enter the list measurement
ds1-log UUCSS command to read the error seconds measurement.
3. Verify that both endpoints of the DS1 link are administered using the
same signaling mode, framing mode, and line coding.
4. Check the active alarm and error logs for recent alarms and errors against
the synchronization (SYNC). Follow the suggested repair procedure for
these errors.
5. Contact T1 Network Service or the technician at the remote switch to
diagnose the remote DS1 endpoint.
6. Check the physical connectivity of the UDS1 interface circuit packs and
the cable.
7. Replace the local UDS1 interface circuit pack, and repeat the test.
