• Check the red LED located on the BRSC faceplate. If the red LED is
extinguished, check that the BRSC is enabled and operating correctly. If
the red LED is lit, check that the BRSC is manually disabled or faulty.
To enable a BRSC or to correct a problem, refer to
ISDN Basic Rate
Interface: Maintenance (553-3001-518).
• Check the red LED located on the SILC and UILC faceplates. If the red
LED is extinguished, check that the SILC or UILC is enabled and
operating correctly. If the red LED is lit, check that the SILC or UILC is
manually disabled or faulty. To enable an SILC or a UILC or to correct
a problem, refer to
ISDN Basic Rate Interface: Maintenance
(553-3001-518).
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 30 on page 94
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 Configuration
(553-3001-218) for ISDN BRI terminal installation instructions.
Procedure 26
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 packet data ISDN BRI terminals.
