Troubleshooting ISDN-PRI Test Call
Problems
An ISDN-PRI test call is placed across an ISDN-PRI user-network interface to a
previously designated number in order to test ISDN capabilities of the switch, the
trunk and the far end. An ISDN-PRI test call is also a maintenance procedure
concerned with the identification and verification ISDN-PRI user-network
interface problems. The ISDN-PRI test call can access ISDN-PRI trunks only.
An ISDN-PRI test call can be placed only if the circuit translates to an ISDN-PRI
trunk. An ISDN-PRI test call can be originated via either the
synchronous
or the
asynchronous
method. Each method is described below.
NOTE:
Before attempting to make an ISDN-PRI test call to the public network (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.
Synchronous Method
One command is used in this method to start, stop and query an ISDN-PRI test
call. In the synchronous method, an outgoing ISDN-PRI test call may be part of
one of the following
long
test sequences entered at the terminal:
■ test trunk grp/mbr long [repeat #]
■ test port UUCSSpp long [repeat #]
■ test board UUCSS long [repeat #]
The
long
qualifier must be entered in the above commands in order for the ISDN
test call to run. The repeat number (#) can be any number from 1 through 99
(default = 1).
The following information is displayed in response to the above commands:
■ Port: The port address (UUCSSpp) is the port network number, carrier
designation, slot, and circuit of the maintenance object under test.
■ Maintenance Name: The type of maintenance object tested.
■ Test Number: The actual test that was run.
■ Test Results: Indicates whether the test passes, fails, or aborts.
■ Error Code: Additional information about the results of the test (See the
ISDN-TRK section of Chapter 9 for details.
