Abstract
In a communication system network that includes a processing multiplexer, a plurality of communication units, and a plurality of communication systems, each of the plurality of communication systems includes a base interface modules for interfacing the communication system with a limited number of repeaters that transceive information amongst the plurality of communication units and a processing multiplexer interface module for interfacing the communication system with the processing multiplexer. Each processing multiplexer interface module includes a base interface database that stores base interface status information of the base interface module of each of the plurality of communication systems that is periodically updated. The base interface database is updated when a processing multiplexer interface module of one of the plurality of communication systems detects a change in the base interface status information of the one of the plurality of communication systems. Once a change is detected, the processing multiplexer interface module stores the change and transmits the change to the processing multiplexer interface module of the other communication systems. The processing multiplexer interface module also transmits unchanged base interface status information at varying time intervals to the processing multiplexer interface module of the other communication systems.
