Figure 9-53. Outgoing ISDN-PRI Test Call
Synchronous Test Calls
You can initiate a synchronous outgoing test call by entering one of the following
commands:
■ test trunk
group#/member#
long [repeat
#
]
■ test board
UUCSS
long [repeat
#
]
■ test port
UUCSSpp
long [repeat
#
]
The above test sequences include a test-call for ISDN-PRI trunks. The duration of
the test call is 8.6 seconds for If 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 the
test isdn-testcall
command described
below.
Asynchronous Test Calls
You can start, query, and stop an outgoing test call by using the following
maintenance commands:
■ test isdn-testcall group#/member# [minutes #]
This command initiates an outgoing ISDN-PRI test call for a maximum of
120 minutes. Default times are as above. Only one trunk per port network
can be tested at one time.
