the default duration of the test call is 8.6 seconds. Otherwise, if the B-channel is
restricted (ZCS) the default duration of the test call is 9.4 seconds. Once the test
call completes, the bit error rate is retrieved from the Maintenance/Test Digital
Port. 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, such as
the test isdn-testcall command.
If no Maintenance/Test circuit pack exists, the outgoing ISDN-PRI test call is
established over a high speed data channel on the Network Control (NETCON)
circuit pack (DATA-BD).
Asynchronous Commands
You can start, query, and stop an outgoing test call by using the following
maintenance commands:
■ test isdn-testcall trunk-group-no/member-no [ minutes ]
This command enables you to start an outgoing ISDN-PRI test call for a
maximum of two hours (120 minutes).
■ status isdn-testcall trunk-group-no/member-no
This command displays the progress of the outgoing test call by reporting
the bit and block error rates of the tested B-channel specified by the "trunk
group no/member no" identifier.
■ clear isdn-testcall trunk-group-no/member-no
This command enables you to stop an outgoing test call already in
progress. The trunk-group-no/member-no identifier specifies the
B-channel used to stop the test call. The measurements are not cleared
until the next test call begins.
NOTE:
Only one trunk can be tested in a given port network, until the test call is
canceled or completes.
