Abstract

본 발명은 전화국으로부터 송출된 에러톤 신호가 입력되면 이를 완충하는 버퍼부와, 상기 버퍼부에서 출력되는 신호에 포함된 잡음을 필터링하는 필터부와, 상기 필터부에서 출력되어 파형정형부를 통과한 신호와 훅크 스위치 상태감지부에서 출력되는 신호를 조합하여 송수화기가 방치되어 있는가를 판별하여 송수화기가 방치되어 있으면 이에 해당된 제어 신호를 출력하는 로직부와, 상기 로직부에서 출력되는 제어 신호에 의해 훅크스위치를 수신 가능하게 전환시켜 수신벨 및 자동 응답 회로가 작동되도록 하는 훅크 스위치 위치조절부로 구성되어, 에러톤을 이용하여 송수화기가 방치상태을 판별하여 훅크 스위치를 수신 가능 상태로 자동 절환 시키므로 송수화기가 전화기 본체로부터 이격되어 있어도 상대 가입자의 수신내용을 기록하거나 수신 벨이 구동되게 하여 상대 가입자와 통화를 할 수 있는 에러톤을 이용한 전화기의 수신 벨 구동 회로에 관한 것이다.The present invention provides a buffer unit for buffering an error tone signal transmitted from a telephone station, a filter unit for filtering noise included in a signal output from the buffer unit, and a signal output from the filter unit and passing through a waveform shaping unit. And the signal output from the hook switch state detection unit to determine whether the handset is left unattended. If the handset is left unattended, the logic unit outputs a control signal corresponding thereto, and the hook switch is controlled by the control signal output from the logic unit. It consists of a hook switch position control unit which switches the receiver so that the reception bell and the answering machine can be operated. Record or receive the other subscriber's To be bell is driven relates to a driving circuit receives bell of a telephone with an error tone to the call with the external subscriber.

Claims (1)

전화국으로부터 송출된 에러톤 신호가 입력되면 이를 완충하는 버퍼부와, 상기 버퍼부에서 출력되는 신호에 포함된 잡음을 필터링하는 필터부와, 상기 필터부에서 출력되어 파형정형부를 통과한 신호와 훅크스위치 상태감지부에서 출력되는 신호를 조합하여 송수화기가 방치되어 있는가를 판별하여 송수화기가 방치되어 있으면 이에 해당된 제어 신호를 출력하는 로직부와, 상기 로직부에서 출력되는 제어 신호에 의해 훅크스위치를 수신 가능하게 전환시켜 수신벨 및 자동 응답 회로가 작동되도록 하는 훅크 스위치 위치조절부로 구성된 것을 특징으로 하는 에러톤을 이용한 전화기의 수신 벨 구동 회로.A buffer unit for buffering an error tone signal transmitted from a telephone station, a filter unit for filtering out noise included in a signal output from the buffer unit, a signal output from the filter unit and a hook switch, and a hook switch By combining the signals output from the state sensing unit, it is determined whether the handset is left. If the handset is left, a logic unit for outputting a control signal corresponding thereto and a hook switch can be received by the control signal output from the logic unit. Reception ring driving circuit of the telephone using the error tone, characterized in that the switch is configured to switch the hook ring position control unit to operate the receiving ring and the answering machine. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
