Abstract:
A wireless communication system having a plurality of base stations interconnected by a common transmission facility that is configured in a channelized format, wherein each of the plurality of base stations comprises:a signal level buffer for receiving data transmitted over the transmission facility; a framer for receiving the data from the signal level buffer, for detecting a beginning of a frame in the data and for outputting the frame with an indicator identifying the beginning of the frame; a time slot interchanger for receiving the frame and the indicator output from the framer, and for outputting predetermined portions of the frame using the indicator; a universal synchronous-asynchronous receiver transceiver for receiving the predetermined portions output from the time-slot interchanger, for examining subsets of the predetermined portions of the frame, for outputting interrupt signals if the subsets are flags, and for outputting the subsets if the subsets are not flags; and a microprocessor for receiving the outputs of the universal synchronous-asynchronous receiver transceiver and examining an identifier associated with a signaling message composed of the outputs of the universal synchronous-asynchronous receiver transceiver which are not interrupt signals.
