ISDN-TRK (DS1 ISDN Trunk)

Whenever a circuit translates to an ISDN-PRI trunk during a Long Test Sequence,
an outgoing test call is invoked. If the B-channel is unrestricted (B8ZS or HDB3)
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

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:
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).
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.
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

NOTE:
Only one trunk can be tested in a given port network, until the test call is
canceled or completes.
