Communication Manager Maintenance Object Repair Procedures
The test sets up a call to a far-end switch over the trunk to be tested. If a Maintenance/Test
circuit pack does not reside in the system, the test call connection is established over the TDM
Bus of the transmit and receive sides of the ISDN-PRI trunk to a data channel.
If a Maintenance/Test circuit pack does reside in the system, the test call connection is
established over the TDM Bus of the transmit and receive sides of the ISDN-PRI trunk to a
digital trunk testing port on the Maintenance/Test circuit pack. The digital port on a TN771D
Maintenance/Test circuit pack sends a bit pattern to the far end which is echoed back. If the
received pattern matches the pattern that was sent, the test passes. If there are differences, the
test fails.
If a test call is running when scheduled maintenance starts, the green LED is turned off. To
determine whether a test call is still running:
● Enter list isdnpri-testcall and status isdnpri-testcall.
● Check for a lit amber LED on the Maintenance/Test circuit pack.
Synchronous Test Calls
Enter one of the following commands to initiate a synchronous outgoing test call:
● test trunk grp#/mem# long [repeat #]
● test board location long [repeat #]
● test port location long [repeat #]
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, perform further diagnostics
such as test isdnpri-testcall.
Asynchronous Test Calls
You can start, query, and stop an outgoing test call by using the following commands:
● test isdnpri-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 isdnpri-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.
● clear isdnpri-testcall grp#/mem#
This command terminates an outgoing test call already in progress. Measurements already
collected are not cleared until the next test call begins.
A PASS of the asynchronous test indicates only that the test call was successfully established.
Enter status and list to get the results of the test.
