5-77Troubleshooting the Outgoing ISDN-Testcall Command
5
The functions of the clear, list, and status co mmands associated with the ISDN
Testcall are summarized below.
clear isdn-testcall: enables you to canc el 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 comp letes 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 b een 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 p rovisioned
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 correc t service so that a network
facility message can b e sent across the ISDN-PRI network.
If the outgoing ISDN-PRI test call keeps abor ting, make sure that the far-end
device can hand le 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 servic e is provisioned
by the network. The user must subscrib e to Test Type 108 service and have
the correct far-end test c all number administered on the trunk group form
for the call to be allowed.
