Abstract: A signalling protocol (70) comprising a plurality of interleaved phases (90a, 90b, 90c and 90d) is transmitted at one of a plurality of baud rates, the plurality of baud rates being multiples of a base baud rate. The signalling protocol (70) allows a selective call receiver (FIG. 5) to decode at an operating baud rate equivalent to the base baud rate irrespective of the transmission baud rate by decoding only a portion (90a, 90b, 90c or 90d) of the transmitted signal, the portion decoded (90a, 90b, 90c or 90d) determined by the baud rate and the address of the selective call receiver.

Abstract: A selective call receiver receives a signal having a baud rate and comprising a number of phases. The number of phases are time division multiplexed to form the signal. The selective call receiver has selective call address information assigned thereto and includes a receiver for receiving and demodulating the signal and a memory for storing predetermined information. A demultiplexer is coupled to the receiver and the memory for demultiplexing the signal to recover one of the number of phases in response to the predetermined information and the baud rate. The selective call receiver also includes a decoder coupled to the demultiplexing means for decoding said one of said number of phases of said signal to derive a selective call message therefrom.
