Table 10-241. TEST #144 Slip Alarm Inquiry Test — Continued
Error
Code Test Result
1 to 88 FAIL
555-233-123
Description/Recommendation
The DS1 interface circuit pack detected a slip alarm. The error
code equals the number of slips detected by the DS1 interface
circuit pack since the last slip alarm inquiry test.
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 connectivity of the DS1 pack and of
the cable.
7. If this continues to fail, escalate this problem.
