Major alarms may be downgraded to Warning alarms based on the value used in set options.
Note:
The section, Isolating and repairing packet-bus faults, in Maintenance Procedures for Avaya Aura® Communication Manager, Branch Gateways and Servers, along with the other information presented in the chapter, can help resolve problems involving more than one station.
Other:
If a significant packet bus failure occurs, errors and alarms may not be logged as expected for BRI-PORT/ABRI-POR/ATT-PORT/ LGATE-PT/ ATTE-PT. Conditions under which this occurs are detailed in the Isolating and repairing packet-bus faults section in Maintenance Procedures for Avaya Aura® Communication Manager, Branch Gateways and Servers.
The following media module support this maintenance object:
  • MM720 BRI Media Module
The MM720 BRI Media Module provides 8 S/T ISDN 2B+D ports that interface to either the central office or another PBX. The MM720 contains eight, 4-wire ports that interface to the network at the ISDN S/T reference point over two 64Kb channels and over a 16Kb signaling channel. The 64Kb channels are B1 and B2, and the 16Kb channel is D. The B1 and B2 channels can be simultaneously circuit switched, or individually packet switched. The D-channel is circuit switched. The circuit-switched connections have a Mu-law or A-law option for voice and operate as 64Kb clear data channels.
Note:
This maintenance object applies to the MM720 BRI Media Module only if its ports are all configured as station line ports instead of trunk ports.
For BRI endpoints, each B-Channel may support voice or circuit-switched data and may be circuit-switched simultaneously. The B-Channels are not used on ports connected to ASAI or Avaya adjuncts. The D-Channel is used for conveying signaling between the switch and a BRI endpoint or endpoints, ASAI or Avaya adjunct. Each ISDN-BRI D-Channel is connected to the switch processor and the ISDN-BRI port through the packet bus.
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 BRI endpoint BRI-SET, or ASAI adjunct ASAI-ADJ/LGATE-ADJ/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, see:
