Abstract

본 발명은 국선라인에 연결되어 입력신호의 극성에 관계없이 정극성 신호로 변환하는 브릿지와, 상기한 브릿지와 연결되어, 제어부로 부터 출력되는 신호에 따라 국선라인을 접속하거나 절단하는 루프단속부와, 루프단속부에 연결되어 전기적신호를 음성신호로 변환시키거나 음성신호를 전기적 신호로 변환시키는 송수화부와, 홀드상태입력을 위한 홀드스위치가 포함되어 있으면서 상대방의 전화번호를 입력시킬 수 있는 다이얼부와, 핸드세트와 물리적으로 연결되어 있는 후크스위치와, 브릿지에 연결되어 국선라인으로 부터의 비지톤을 감지하는 톤 검출부와, 브릿지에 연결되어 제어부의 출력신호에 따라 국선라인을 홀드시키는 홀드회로부와, 송수화부와 다이얼부와 후크스위치와 톤 검출부와 홀드회로부에 연결되어, 홀드상태에서 상대방이 전화를 끊어 버릴 경우에 국선라인을 자동으로 절단하는 모든 동작을 제어하는 제어부로 구성되어, 전화가 홀드된 상태에서 상대방이 통화를 끊어 버리는 경우에 자동으로 국선라인을 절단함으로써 그 이후에 다른 곳에서 걸려오는 중요한 전화가 신속하게 감지될 수 있는 국선라인 자동절단 장치 및 방법에 관한 것이다.The present invention includes a bridge connected to a trunk line to convert a positive signal regardless of the polarity of the input signal, and a loop interrupter connected to the bridge to connect or cut the trunk line according to a signal output from the controller. Is connected to the loop control unit, and includes a handset for converting an electrical signal into a voice signal or a voice signal into an electrical signal, and a dial switch for inputting a phone number of the other party while holding a switch for holding a state input A hook switch physically connected to the handset, a tone detector connected to the bridge to sense busy tone from the trunk line, and a hold circuit unit connected to the bridge to hold the trunk line according to the output signal of the controller; Connected to the handset, the dial, the hook switch, the tone detector, and the hold circuit. It consists of a control unit that controls all operations to automatically cut the CO line when the call is cut off, and when the other party disconnects the call while the phone is held, the CO line is automatically cut. The present invention relates to a trunk line automatic cutting device and a method for quickly detecting an important incoming call.
