1 to 88 FAIL The test failed because the UDS1 interface circuit pack and the remote
DS1 endpoint are not synchronized to the same clock rate. The UDS1
interface circuit pack detected a slip alarm. The error code equals the
number of slips detected by the UDS1 interface circuit pack since the last
slip alarm inquiry test.
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.
