3-1057TBRI-TRK (TN2185 ISDN Trunk-Side BRI)
3
There are two methods available to place an outgoing ISDN Trunk-side BRI trunk
test call:
1. The test call connection is established over the TDM Bus of the transmit
and receive sides of the ISDN Trunk-side BRI trunk to a data channel.
2. The test call connection is established over the TDM Bus of the transmit
and receive sides of the ISDN Trunk-side BRI trunk to a digital trunk testing
port on the Processor circuit pack. The Processor Digital Port generates a
pseudo bit stream.
A test is run periodically to check if the call is hung. If so, it gracefully tears down
the call to release the resources.
Synchronous Commands
You can demand a synchronous outgoing test call by using the following
maintenance commands:
■ test trunk trunk-group-no/member-no long [repeat number]
■ test board board-location long [repeat number]
■ test port port-location long [repeat number]
Whenever a circuit translates to an ISDN Trunk-side BRI trunk during a Long Test
Sequence, an outgoing test call is invoked, and the duration of the test call is 8.6
seconds. The outgoing ISDN Trunk-side BRI trunk test call is established over a
high speed data channel on the Processor circuit pack (DATA-BD). A bit error
rate greater than zero is reported as a failure to the Manager I terminal (MGRI). A
failure indicates the need to run further diagnostics.
Asynchronous Commands
NOTE:
Only one trunk can be tested in a given port network, until the test call is
canceled or completes.
