Avaya 03-300430 User Manual

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 list 

measurement ds1-log location 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.
