Testing ISDN BRI functions

The following describes some ISDN BRI tests used to verify the operation of
ISDN BRI features. The tests include basic call connections, voice and data
transmission, and verification of features using ISDN BRI terminals.
The tests are divided into:

— voice calls

— circuit-switched data calls
— B-channel and D-channel packet data calls
Voice calls
A voice call can be established between two voice terminals across a network
(ISDN or non-ISDN), between two terminals on the same Option 11, and
between two terminals on the same DSL.
Acceptance testing of ISDN BRI voice calls is conducted when testing the
following basic system features supported by ISDN BRI terminals:
— Call hold/call retrieve
— Call waiting
— Call forward no answer
— Call forward busy
— Calling line identification presentation and restriction
— Hunting
— Message waiting (audible)
