とする電話装置の発呼者選択回路。 In a telephone device equipped with a caller selection function that emits a ringing signal when the number corresponding to the DTMF signal sent by the caller after receiving a call matches the PIN number, the caller selection function is not activated. a first ringing signal generation circuit that becomes active when a ringing signal arrives and generates a ringing signal; and a DT that is transmitted by a calling party when in a caller selection operating state.
a number matching circuit that matches the number corresponding to the MF signal with the password and outputs a drive signal when the numbers match; and a number matching circuit that outputs a drive signal when the numbers match; 1
A second ringing signal generating circuit generates a ringing signal different from that of the ringing signal generating circuit, and when an incoming call operation is performed in response to the arrival of a ringing signal in the calling party selection operating state, the circuit enters an operating state for a predetermined period of time, a ringing operation control circuit that outputs a drive signal for activating the second ringing signal generating circuit when a second ringing operation is performed within the time; Caller selection of a telephone device, characterized in that the ringing signal outputted from the signal generation circuit and the ringing signal outputted from the second ringing signal generation circuit are made different by the drive signal of the ringing operation control circuit. circuit.
