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 has been 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
