Introduction
This chapter describes how to prepare ISDN BRI equipment for acceptance testing. It explains
how to verify that ISDN BRI cards are enabled and functioning correctly and how to correct
any problems before starting the test.
Verifying ISDN BRI operation
After ISDN BRI equipment is installed and configured, you can visually inspect ISDN BRI cards
to make sure that they are operating correctly by observing their LEDs:
• Check the red Dis LED located on the MISP faceplate. If the Dis LED on an MISP is lit,
check that the MISP is disabled or faulty. If it is extinguished, check that the MISP is
enabled and operating. To enable the MISP or to correct a problem, refer to Avaya ISDN
Basic Rate Interface Maintenance (NN43001-718).
• 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 Avaya
ISDN Basic Rate Interface Maintenance (NN43001-718).
• 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
