or a UILC or to correct a problem, refer to Avaya ISDN Basic Rate Interface Maintenance
(NN43001-718).
If all indicator LEDs on ISDN BRI equipment are extinguished (with the exception of the CC
LED on an MISP), the equipment is functional and you can set up the terminals for this test.
Setting up ISDN BRI test terminals and trunks
Set up ISDN BRI terminals
To conduct acceptance testing for ISDN BRI terminals, you must have a setup that can verify
basic ISDN BRI functions and features.
terminals
on page 47 shows an example of the ISDN BRI terminal arrangement. You may
wish to establish a different test setup, which can be determined by the type of terminals
implemented in a specific customer configuration. You may want to setup communication
between ISDN BRI and non-ISDN terminals.
Refer to the Avaya ISDN Basic Rate Interface Installation and Commissioning (NN43001-318)
for ISDN BRI terminal installation instructions.
Performing acceptance testing
To perform acceptance testing of ISDN BRI terminals:
1. Select three DSLs, two connected to different SILCs and one to a UILC.
2. Equip each SILC DSL with two voice, one circuit-switched data, and one low speed
3. Equip the UILC DSL with a network terminator (NT1) and connect the two voice and
4. Configure the DSLs to support these ISDN BRI terminals and initialize the terminals
After you have completed the setup to perform acceptance testing, proceed with the tests

packet data ISDN BRI terminals.
Note:
Packet data testing can be conducted only if an external packet handler or an
Meridian Packet Handler (MPH) is installed as part of the customer configuration,
and is supported by the system (like the external DPN-100 packet handler). If
packet handler is not part of the configuration, do not equip the DSLs with packet
data terminals and skip all the packet data tests specified in this chapter.
