Figure 10-9. ISDN-BRI Set Interactions
This section contains the ISDN-BRI Set, ASAI Adjunct, and AT&T Adjunct
Maintenance documentation. Some of the results of maintenance testing of the
ISDN-BRI Set or the ASAI and AT&T Adjunct may be affected by the health of the
ISDN-BRI circuit pack and Port. These interactions should be kept in mind when
investigating the cause of ISDN-BRI Set problems.
