1. An automatic paging telephone set comprising:
- a mode selecting switch having first, second, and third settings according to a paging number recording mode, a paging mode and a general communications mode, respectively, connected between a power source and a system controller;
said system controller having a second memory for storing paging number information input from a first dual tone multi-frequency transmitter in response to said mode selecting switch being set in said first setting and a third memory for storing caller number information transmitted by a caller to the telephone set while said mode selecting switch is in said second setting;
a switching circuit, connected to a telephone line, comprising a hook switch driven by a transceiver and a relay switch driven by said system controller via a relay driver for establishing or interrupting a communication channel;
a second dual tone multi-frequency transmitter for receiving data from said controller and for converting said data to a dual tone multi-frequency;
a communication circuit having a first input connected to an output of said first dual tone multi-frequency transmitter and to an output of said second dual tone multi-frequency transmitter, a second input connected to an output of said transceiver, an input-output line connected to said telephone line via said switching circuit and an output connected to said transceiver, a tone detector and a dual tone multi-frequency receiver;
said dual tone multi-frequency receiver digitizes said paging number information transmitted in a dual tone multi-frequency from said first dual tone multi-frequency transmitter and said caller number information transmitted in a dual tone multi-frequency from said caller for storage in said second and third memories, respectively; and
a ring detector connected to said telephone line for driving a speaker and for providing a ring detected signal to said system controller.

Abstract
An automatic paging telephone set comprising first and second DTMF transmitters, a mode selector for selecting either a pager number recording mode, a paging mode, or a general communication mode, and a controller for controlling the telephone set according to the mode selected by the mode selector.
