10-1900 Issue 4 May 2002
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 for a maximum of 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.
