The functions of the clear, list, and status commands associated with the ISDN
Testcall are summarized in the following list. For more detailed information, refer
to the appropriate sections as directed.
■
Clear isdn-testcall <grp>/<mbr> enables you to cancel an in-progress
ISDN-PRI test call and allow another test call to start. For details on this
command, refer to the clear isdn-testcall command description in the
“Clear Commands” section of
Chapter 8, ‘‘Maintenance Commands and
Trouble-Clearing Aids’’ .
■
List isdn-testcall <grp>/<mbr> enables you to list all the ISDN-PRI trunks
in use for an ISDN-PRI test call in the system. For details on this command,
refer to the list isdn-testcall command description in the “List Commands”
section of
Chapter 8, ‘‘Maintenance Commands and Trouble-Clearing
Aids’’ .
■
Status isdn-testcall <grp>/<mbr no> [minutes] 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). For details on this command, refer to the
status isdn-testcall command description in the “Status Commands”
section of
Chapter 8, ‘‘Maintenance Commands and Trouble-Clearing
Aids’’ .
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:
■
0—Voice
■
1—Digital Communications Protocol Mode 1
■
2—Mode 2 Asynchronous
■
3—Mode 3 Circuit
■
4—Digital Communications Protocol Mode 0 (which is usually the default).
NOTE:
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, please 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
