FAIL If the UDS1 connects to a T1 network facility or to another
switch, do the following:
1. The performance of the DS1 link between the UDS1
interface circuit pack and the remote DS1 endpoint is very
poor. Enter the list measurement ds1-log UUCSS
command to read the error seconds measurement.
2. Verify that both endpoints of the DS1 link are administered
using the same signaling mode, framing mode, and line
coding.
3. Contact T1 Network Service or the technician at the remote
switch to diagnose the equipment.
4. Check the physical connectivity of the UDS1 interface circuit
packs and the cable.
5. Replace the local UDS1 interface circuit pack, and repeat
the test.
FAIL
(cont’d.) If the UDS1 connects to a line-side terminating device (for
example, a PRI terminal adapter), do the following:
1. The performance of the DS1 link between the UDS1
interface circuit pack and the line-side terminating device is
very poor. Enter the list measurement ds1-log UUCSS
command to read the error seconds measurement.
2. Verify that the switch DS1 and the line-side terminating
device are administered using the same signaling mode,
framing mode, and line coding.
3. Investigate the maintenance status of the line-side
terminating device. Refer to the ’Line-Side Terminating
Device Operating Manual’ for information.
4. Contact the vendor of the line-side terminating device to
diagnose the equipment.
5. Check the physical connection of the UDS1 interface circuit
pack to the terminating device, and check the premise
distribution system (or the intra-premise wiring) for physical
connection failures.
6. Replace the local UDS1 interface circuit pack and repeat the
test.
