摘要:
In a communication system network that comprises a plurality of communication systems and a processing multiplexer, each of the plurality of communication systems is equipped with fallback operation circuitry. The fallback operation circuitry enables a communication system to operate as a standalone system when the interface buses that connect it to the processing multiplexer fail. In addition, the fallback operation circuitry enables the communication system to be reconnected to the processing multiplexer when the interface buses resume proper operation.

System configuration data required for use by various interfaces (102) can be obtained either directly via a data link (104) that couples the interfaces to other systems (109 or 111), or by a down link from a system data manager (106) configured as part of the interfaces' system (100).
摘要:
A communication resource method is set forth that allows communication with a subscriber unit that is in a priority access mode. Either a communication resource allocator or a subscriber unit is enabled to initiate a priority communication state in which a subscriber unit is accessible to reception of radio transmissions during the subscriber unit's priority mode status.
