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-AJ/LGATE-AJ) or AT&T adjunct (ATT_AJ/ATTE-AJ). These 
interactions should be kept in mind when investigating the cause of ISDN-BRI 
port problems. For more information on the circuit pack and endpoints, refer to 
the BRI-BD (ISDN-BRI Line Circuit Pack) Maintenance documentation, the 
BRI-SET (ISDN-BRI Endpoint) Maintenance documentation, and ASAI-AJ 
(Adjunct-Switch Application Interface) Maintenance documentation, ATT-AJ 
(AT&T Adjunct) Maintenance documentation, LGATE-AJ (Ethernet 
Adjunct-Switch Application Interface) Maintenance documentation, and ATTE-AJ 
(Ethernet AT&T Adjunct) Maintenance documentation.
