5-77Troubleshooting the Outgoing ISDN-Testcall Command
5
The functions of the
clear
,
list
, and
status
commands associated with the ISDN
Testcall are summarized below.
clear isdn-testcall
: enables you to cancel an in-progress ISDN-PRI test call and
allow another test call to start.
list isdn-testcall
: enables you to list all the ISDN-PRI trunks in use for an
ISDN-PRI test call in the system.
status isdn-testcall
: enables you to check on the progress of an outgoing test
call. When an outgoing ISDN-PRI test call completes in a specific port network,
another ISDN-PRI trunk from the same port network is available for testing
(regardless of whether the
status
information has been displayed).
Troubleshooting the Outgoing
ISDN-Testcall Command
If the TestCall BCC field appears on the Trunk Group Administration Form, make
sure the TestCall BCC field indicates the correct BCC for the service provisioned
on the ISDN-PRI trunk. The TestCall BCC values are defined as follows:
If the ISDN-PRI trunk is of type
cbc
make sure the TestCall Service field on the
Trunk Group Administration Form indicates the correct service so that a network
facility message can be sent across the ISDN-PRI network.
If the outgoing ISDN-PRI test call keeps aborting, make sure that the far-end
device can handle DCP Mode 0 or DCP Mode 1.
NOTE:
Before attempting to make an ISDN-PRI test call to the public network (that
is, the network is the far-end), make sure that test call service is provisioned
by the network. The user must subscribe to Test Type 108 service and have
the correct far-end test call number administered on the trunk group form
for the call to be allowed.
