DS1-BD (DS1 Interface Circuit Pack)
Issue 1 June 2005 1019
1 to 88 FAIL 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 up to 5 times.
2. If the DS1 interface circuit pack is a TN767, enter list
measurement ds1-log location 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.
PASS No Slip alarm is detected on the DS1 Interface circuit pack.
