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 PCSS 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.
