Information for isolating and resolving packet bus faults is included in Isolating and repairing packet-bus faults section in Maintenance Procedures for Avaya Aura® Communication Manager, Branch Gateways and Servers. The Troubleshooting Packet Bus Problems flowchart, along with the other information presented in the chapter, can help resolve problems that involve more than a single station.
Warning:
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 in Maintenance Procedures for Avaya Aura® Communication Manager, Branch Gateways and Servers.
ISDN-BRI endpoints come in a number of configurations. Every endpoint requires the D-Channel to convey signaling information to the switch. A voice-only set requires only one B-Channel. A voice and data-capable set requires both B-Channels. One of them is for voice and the other one is for data. Only a single ASAI or Avaya adjunct may be connected to an ISDN-BRI port. Multiple adjuncts per line are not supported.
The figure illustrates the physical connection between an ISDN-BRI media module and a voice or voice/data set. The connection is represented by a solid line. Each physical connection allows for two B-Channels, as stated above, plus one D-Channel.
Figure : 1. ISDN-BRI Set Interactions
This section contains the ISDN-BRI Set, ASAI Adjunct and Avaya Adjunct Maintenance documentation. Some of the results of maintenance testing of the ISDN-BRI Set or the ASAI and Avaya Adjunct may be affected by the health of the ISDN-BRI media module and port. These interactions should be kept in mind when investigating the cause of ISDN-BRI Set problems.
The alarm level for ASAI and Avaya adjuncts may be administered using set options. The alarm level can be set independently for on- and off-board alarms to WARNING, MINOR, or MAJOR for every ASAI and Avaya adjunct in the system.
Alarming for an ASAI and Avaya adjuncts is disabled if the adjunct asks the switch to suspend maintenance. When this occurs, an error and a WARNING alarm are logged against the endpoint. Busying out and releasing the ASAI station or ADDLE station will clear the alarm.
