Verifying ISDN BRI operation

Setting up ISDN BRI test terminals and trunks

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, the MISP is disabled or faulty. If it is extinguished, the
MISP is enabled and operating. To enable the MISP or to correct a
problem, go to MISP fault isolation and correction in the Service
changes and maintenance section of this guide.
— Check the red LED located on the SILC and UILC faceplates. If the red
LED on an SILC or a UILC is extinguished, that SILC or UILC is
enabled and operating correctly. If the red LED is lit, that SILC or UILC
is manually disabled or faulty. To enable an SILC or a UILC or to correct
a problem, go to SILC or UILC fault isolation and correction in the
Service changes and maintenance section of this guide.
If all indicator LEDs on ISDN BRI equipment are extinguished (with the
exception of the CC LED on a MISP), the equipment is functional and you
may proceed with setting up the terminals you wish to use for this test.
Designating ISDN BRI test terminals
To conduct acceptance testing, you must have a setup that can verify basic
ISDN BRI functions and features. Figure 53 shows an example of the ISDN
BRI terminal arrangement. You may wish to establish a different test setup,
which may be determined by the type of terminals implemented in a specific
customer configuration. You may want to set up communication between
ISDN BRI and non-ISDN terminals.
