correct a problem, refer to 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. Figure 13 "ISDN BRI acceptance testing setup for terminals" (page 49) 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 ISDN Basic Rate Interface Installation and Commissioning (NN43001-318) for ISDN BRI terminal installation instructions.

Procedure 13

Performing acceptance testing

Step Action

To perform acceptance testing of ISDN BRI terminals:

1Select three DSLs, two connected to different SILCs and one to a UILC.

2Equip each SILC DSL with two voice, one circuit-switched data, and one low speed 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.

3Equip the UILC DSL with a network terminator (NT1) and connect the two voice and one circuit-switched data ISDN BRI terminal to the S/T interface on the NT1.

4Configure the DSLs to support these ISDN BRI terminals and initialize the terminals as described in the "Initialize ISDN BRI terminals" section of the ISDN Basic Rate Interface Feature Fundamentals (NN43001-580).
