  • Patent number: 3995121
    Abstract: A telephone paging system includes a central interconnect station responsive to phoned information for automatically transmitting the caller's verbal message to a designated portable paging receiver. The central station instructs the caller by means of a prerecorded message to provide a brief voice message preceded by touch tone or rotary dial digits identifying the receiver to be paged. The paging code digits and message are both tape-recorded by the central station. If the transmitter is free, the recorded paging code is automatically played back through a decoding circuit responsive to rotary dial clicks as well as touch tones. The output of the decoding circuit keys a radio transmitter which transmits a corresponding code followed by the recorded voice message. The central station employs a plurality of recorders. If one recorder is in operation, an incoming call is transferred to the next recorder. Recordings awaiting access to the transmitter are taken in a predetermined order.
