Table 6-25: Troubleshooting Control Link Failure

 Step Action

1 Verify the span settings using the span_view command on the active master GLI2 MMI port. If

these are correct, verify the edlc parameters using the

show command. Any alarms conditions

indicate that the span is not operating correctly.

– Try looping back the span line from the DSX panel back to the Mobility Manager (MM) and

verify that the looped signal is good.

– Listen for control tone on appropriate timeslot from Base Site and MM.

2 If no traffic channels in groomed MCCs (or in whole C–CCP shelf) can process calls, verify that

the ISB cabling is correct and that ISB A and ISB B cables are not swapped.
