Table 10-242. TEST #145 Misframe Alarm Inquiry Test — Continued
Error
Code Test Result
ANY FAIL
PASS
10-660 Issue 4 May 2002
Description/Recommendation
The test failed because the DS1 interface circuit pack detected
errors in the received framing bits pattern. The error code
equals the number of misframes detected by the DS1 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.
1. Retry the command at 1-minute intervals a maximum of 5
times.
2. If the DS1 interface circuit pack is a TN767, enter the list
measurement ds1-log UUCSS command to read the
error seconds measurement.
3. Verify that both endpoints and all intermediate equipment
of the DS1 link are administered using the same signaling
mode, framing mode, and line coding.
4. If the DS1 interface circuit pack connects to a T1 facility,
call the vendor of the T1 carrier to diagnose the remote
DS1 endpoint. If the DS1 interface circuit pack connects
directly to a switch, call the system technician of the
remote switch to diagnose the DS1 endpoint.
5. Check the active alarm and error logs for recent alarms
and errors against the synchronization (SYNC). Follow the
suggested repair procedure for these errors.
6. Check the physical connection of the DS1 pack and of the
cable.
7. If this continues to fail, escalate this problem.
No Misframe alarm is detected on the DS1 Interface circuit
pack.
