In the telephone device, a tone receiving circuit is connected to the telephone line upon detecting that the ring tone has sounded a predetermined number of times, and an output from the tone receiving circuit that receives a tone signal sent from outside through the telephone line. A telephone device comprising: a control circuit that varies a ringing volume source in accordance with data and supplies the variable volume signal to the ringing tone generating circuit.

Claims

[Scope of utility model registration request]

A telephone device comprising an incoming call detection circuit and a transmitting/receiving circuit that are alternately connected to a telephone line in conjunction with attachment and detachment of the handset, and a ring tone generating circuit that generates a ring tone in response to an output signal of the incoming call detection circuit, A tone receiving circuit is connected to the telephone line upon detecting that the ringing tone has sounded a predetermined number of times, and in response to output data from the tone receiving circuit which has received a tone signal sent from outside through the telephone line. A telephone device comprising a control circuit that varies a ringing volume source and supplies the variable volume signal to the ringing tone generating circuit.
