Alarms, Errors, and Troubleshooting
555-233-143
4-74 Issue 1 May 2002
NOTE:
If the flowchart query “Is the problem affecting MOs on multiple BRI-BD
circuit packs?” is reached and the EPN in question has only one ISDN-BRI
circuit pack, then assume that the answer is “Yes,” and follow the repair
procedure for PKT-BUS.
When directed by the flowchart to refer to the maintenance documentation for a
specific MO, keep in mind that the repair procedure for that MO may refer you to
another MO’s repair procedure. The flowchart tries to coordinate these activities
so that a logical flow is maintained if the ISDN-BRI problems are not resolved with
the first set of repair procedures.
These following status commands may also be useful when diagnosing
ISDN-BRI problems:
■ status port-network
■ status packet-interface
■ status bri-port
■ status station
■ status data-module
