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 pac k 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 pack s and the
cable.
7. Replace the loc al UDS1 interface circ uit pack, and rep eat the test.

(cont’d.)
If the UDS1 connects to a line-side terminating device (for example, a PRI
terminal adapter), do the following:
1. Retry the command at 1-minute intervals for a maximum of 5 times.
2. Enter the list measurement ds1-log UUCSS command to read the error
seconds measurement.
3. Verify that the switch DS1 and the line-side terminating device are
administered using the same signaling mode, framing mode, and line
coding.
4. Investigate the maintenance status of the line-side terminating device.
Refer to the ’Line-Side Terminating Device Operating Manual’ for
information.
5. Contact the vendor of the line-side terminating device to diag nose the
equipment.
6. Check the physical connection of the UDS1 interface circuit pac k to the
terminating devic e, and check the p remise distribution syst em (or the
intra-premise wiring) for physical connection failures.
7) Replace the local UDS1 interface circuit pack and repeat the test.
