1. In a cellular, communication system comprised of a plurality of base stations coupled to a wireline network having fixed sites connected thereto, a radio transceiver having transmitter circuitry operative to transmit a fixed number of call sequences to a base station of the cellular communication system to effectuate thereby telephonic communication between the radio transceiver and fixed sites of the wireline network associated with the call sequences transmitted by the transmitter circuitry, the combination with the transmitter circuitry of:

  • means forming a first memory location for storing a first call sequence therein;

    means for initiating transmission by the transmitter circuitry of the first call sequence stored in the first memory location;

    means forming a second memory location for storing a second call sequence therein; and

    means for initiating transmission by the transmitter circuitry of the second call sequence stored in the second memory location only after effectuation of telephonic communication between the radio transceiver and the first fixed site and termination of telephonic communication therebetween.
