Figure 82: ISDN-PRI Outgoing Test Call
Synchronous Test Calls
Use one of the following commands to initiate a synchronous outgoing test:
● test trunk grp#/mem# long [repeat #]
● test board address long [repeat #]
● test port address long [repeat #]
The previous test sequences include a test call for ISDN-PRI trunks. The duration of the test call
is 8.6 seconds for unrestricted (B8ZS) B channels and 9.4 seconds for restricted (ZCS) B
channels. The test fails if the bit error rate retrieved from the Maintenance/Test digital port is
greater than 0. When this occurs, you will need to perform further diagnostics, such as test
isdn-testcall described below.
Asynchronous Test Calls
You can start, query, and stop an outgoing test call by using the following maintenance
commands:
● test isdn-testcall grp#/mem# [minutes #]
This command initiates an outgoing ISDN-PRI test call up to 120 minutes. Default times are
as above. Only one trunk per PN can be tested at one time.
● status isdn-testcall grp#/mem#
This command displays the progress of the outgoing test call by reporting bit and block error
rates of the tested B channel.
