48 Preparing the systemcorrect a problem, refer to ISDN Basic Rate Interface Maintenance(NN43001-718).If all indicator LEDs on ISDN BRI equipment are extinguished (with theexception of the CC LED on an MISP), the equipment is functional and youcan set up the terminals for this test.Setting up ISDN BRI test terminals and trunksSet up ISDN BRI terminalsTo conduct acceptance testing for ISDN BRI terminals, you must have asetup that can verify basic ISDN BRI functions and features. Figure 13"ISDN BRI acceptance testing setup for terminals" (page 49) shows anexample of the ISDN BRI terminal arrangement. You may wish to establisha different test setup, which can be determined by the type of terminalsimplemented in a specific customer configuration. You may want to setupcommunication 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 13Performing acceptance testingStep ActionTo perform acceptance testing of ISDN BRI terminals:1 Select three DSLs, two connected to different SILCs and one toa UILC.2 Equip each SILC DSL with two voice, one circuit-switched data, andone low speed packet data ISDN BRI terminals.Note: Packet data testing can be conducted only if an externalpacket handler or an Meridian Packet Handler (MPH) is installedas part of the customer configuration, and is supported by thesystem (like the external DPN-100 packet handler). If packethandler is not part of the configuration, do not equip the DSLswith packet data terminals and skip all the packet data testsspecified in this chapter.3 Equip the UILC DSL with a network terminator (NT1) and connectthe two voice and one circuit-switched data ISDN BRI terminal to theS/T interface on the NT1.4 Configure the DSLs to support these ISDN BRI terminals andinitialize the terminals as described in the "Initialize ISDN BRIterminals" section of the ISDN Basic Rate Interface FeatureFundamentals (NN43001-580).Nortel Communication Server 1000ISDN Basic Rate Interface Installation and CommissioningNN43001-318 01.02 StandardRelease 5.0 20 June 2007Copyright © 2003-2007, Nortel Networks.
