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 cap abilities of the switch, the
trunk and the far end. An ISDN-PRI test call is also a maintenanc e procedure
concerned with the id entification and verific ation ISDN-PRI user-network
interface problems. The ISDN-PRI test call can ac cess 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 eith er the

synchronous

or the

asynchronous

method. Each method is described below.
NOTE:
Before attempting to make an ISDN-PRI test call to the pub lic network (the
far-end), make sure that test call service is p rovisioned by the network. The
user must subscribe to Test Type 108 service and have the c orrect far-end
test call number adminis tered on the trunk group form for the c all to be
allowed.

Synchronous Method

One command is used in thi s method to start, stop and q uery an ISDN-PRI test
call. In the synchronous method, a n outgoing ISDN-PRI test call may be part of
one of the following

long

test sequences entered at the te rminal:
■test trunk grp/mbr long [repeat #]
■test port UUCSSpp long [repeat #]
■test board UUCSS long [repeat #]
The long qualifie r must be entered in the above com mands in order for the ISDN
test call to run. The repeat number (#) c an be any number from 1 through 99
(default = 1).
The following information is disp layed in response to the above c ommands:
■Port: The port address (UUCSSpp) is the p ort network number, carrier
designation, slot, and c ircuit of the maintenance objec t under test.
■Maintenance Name: The type of maintenance o bject tested.
■Test Number: The actual test that was run.
■Test Results: Indicates whether the test passes, fails, or aborts.
■Error Code: Additional information ab out the results of the test (See the
ISDN-TRK section of Chapter 9 for details.
