Maintenance-Object Repair Procedures

This section covers the maintenance documentation for ISDN-BRI ports. Some of
the results of maintenance testing of ISDN-BRI ports may be affected by the
health of the ISDN-BRI Line circuit pack (BRI-BD), BRI endpoint (BRI-SET), or
ASAI adjunct (ASAI-ADJ/LGATE-AJ/LGATE-AJ) or Avaya adjunct
(ATT-ADJ/ATTE-AJ). These interactions should be kept in mind when
investigating the cause of ISDN-BRI port problems. For more information about
the circuit pack, see:
■ ‘‘BRI-BD/LGATE-BD (ISDN-BRI Line Circuit Pack)’’ on page 8-321
■ ‘‘BRI-SET, ASAI-ADJ, BRI-DAT’’ on page 8-354
and its endpoints, see:
■ ASAI-ADJ (Adjunct-Switch Application Interface)
■ ATT-ADJ (Avaya Adjunct) Maintenance documentation
■ ‘‘LGATE-AJ’’ on page 8-1013
■ ATTE-AJ (Ethernet Avaya Adjunct) Maintenance documentation
