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 UUCSS 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.
