Troubleshooting ISDN-BRI/ASAI Problems
5
describes the steps needed to isolate and resolve
ISDN-BRI problems. The order in which you should examine the maintenance
objects is determined by looking at how widespread the failure is. For example,
since all ISDN-BRI devices communicate with the TN1655 Packet Interface
circuit pack, this MO should be examined early in the sequence. On the other
hand, a failure of an Expansion Interface (TN570) circuit pack may cause
ISDN-BRI failure in an EPN, but could not be the cause of a failure in the PPN.

NOTE:
If the flowchart query ‘‘Is the problem affecting MOs on multiple BRI-BD
circuit packs?’’ is reached and the port network in question has only one
ISDN-BRI circuit pack, then assume that the answer is ‘‘Yes’’ and follow the
repair procedure for PKT-BUS.

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:
ISDN-BRI problems:
■
status port-network
■
status packet-interface
■
status bri-port
■
status station
■
status data-module
