Error Log Entries and Test to Clear Values
Notes:
a. This error indicates a problem with the primary DS1 reference. It will be
cleared when the primary reference is restored. The following procedure
should indicate the problem’s source:
1. Enter list configuration board UUCSS to check if the primary DS1
Interface circuit pack is inserted in the carrier.
2. Verify that the administered primary reference matches the DS1
reference from the network synchronization plan.
3. Enter test board UUCSS long to test the primary DS1 Interface
circuit pack.
Check the Error Log for DS1-BD or UDS1-BD errors and see
‘‘DS1-BD (DS1 Interface Circuit Pack)’’ or ‘‘UDS1-BD (UDS1
Interface Circuit Pack)’’ on page 8-1707 to resolve any errors
associated with the primary DS1 (DS1 or UDS1) interface circuit
pack.
If the only errors against DS1-BD or UDS1-BD are slip errors, then
follow the procedures described in the previous troubleshooting
section. If no errors are listed in the Error Log for the primary DS1
Interface circuit pack, continue with the following steps.
4. Enter test Tone-Clock UUC long to test the active Tone-Clock
circuit pack in the master port network.
Check the Error Log for TDM-CLK errors, and verify that TDM Bus
Clock Circuit Status Inquiry test (#148), passes.
