Note: When changing configuration settings on the ACS-PRI/BRI card, set STATE to conf
(for “configure”), make changes and then set STATE to actv. Selecting stdby will
cause the configuration information for that D-channel to return to the default
parameters.
4. The Call Status Screen will indicate if any calls are currently connected through the
ACS-PRI/BRI card. Review the Call Status Screen to determine if calls from any of the
ISDN ports are currently active. Generate calls through the ACS-PRI/BRI card and
review the performance register information (accessed by pressing P from the
ACS-PRI/BRI Main Screen) for the affected D-channel(s). This will assist is
determining the extent and possible cause of call failures (error disconnects, call
attempt, call rejected, etc.). Many configuration parameters can affect an ISDN call.
Verify that all configuration options (routing, B-channel assignment and status, etc.)
are correct before proceeding.

5. If an HSU card is being used to originate or receive ISDN calls, additional circuit tests
can be performed. Once an end-to-end call is established, use the loopback and test
signal functions of the HSU card to test the affected port. These tests are accessible
from the HSU Card Main Screen and associated Test Screen, as described in the HSU
chapter. They allow you to test the end-to-end circuit path for that call.
6. If the ACS-PRI/BRI card is determined to be faulty, replace it and return the faulty unit
for repair to the location specified by your distributor.
