Troubleshooting ISDN-PRI Test Calls

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 through either the synchronous or

the asynchronous method. Each method is described in the following sections.

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

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's number, carrier

designation, slot, and circuit of the maintenance object (MO) under test.

Maintenance Name: The type of MO 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. For
