Abstract

본 발명은 1가입자번호에서 수 대의 전화기를 병렬 연결하여 사용하는 경우 임의의 전화기를 통해서 통화로가 형성된 상태에서 다른 전화기의 송수화기를 들게 되면 이 전화기의 기능을 일시 정지시킴과 더불어 그 송수화기를 통해 소정의 멜로디를 출력함으로써 우선 사용자의 비밀을 보호할 수 있도록 된 비밀번호 기능을 갖춘 전화기에 관한 것으로, 훅쿠검출수단을 구비한 여러 대의 전화기를 병렬로 연결한 저화시스템에 있어서, 상기 혹크검출수단의 전단에 설치되어 오프훅을 검출하게 되면 소정 레벨의 신호를 출력하기 제 1 훅검출수단과, 상기 훅크검출수단의 후단에 설치되어 오프훅을 검출하게 되면 소정 레벨의 신호를 출력하기 위한 제 2 훅검출수단, 소정의 음을 송출하기 위한 음송출수단, 송수신자의 음성신호 및 측음에 대한 신호처리 등을 수행하기 위한 네트워크회로 및, 상기 제 1 훅검출수단으로부터 오프훅이 검출된 상태에서 상기 제 2 검출수단으로부터 오프훅이 검출되게 되면 상기 네트워크회로를 제어하여 송수신자의 음성신호를 차단함과 더불어 상기 멜로디 발생수단을 구동제어하여 소정의 음을 송출하도록 제어하는 제어수단을 포함하여 구성된 것을 특징으로 한다.In the present invention, when using a plurality of telephones connected in parallel in one subscriber number, if you pick up the handset of another phone in a state in which a call path is formed through an arbitrary phone, the function of the phone is paused and the predetermined number of handsets are used. The present invention relates to a telephone having a password function that can protect a user's secret by outputting a melody of the present invention. In a lowering system in which several telephones having hook signals are connected in parallel, a front end of the hook detection means is provided. A first hook detecting means for providing a signal of a predetermined level when the off-hook is detected and installed at a rear end of the hook detecting means, and a second hook detecting means for outputting a signal of a predetermined level when the off-hook is detected when the off-hook is detected. Signal processing for sound transmitting means for transmitting a predetermined sound, voice signal and side sound of a transceiver A network circuit for performing an operation, and when the off-hook is detected from the second detection means while the off-hook is detected from the first hook-detecting means, the network circuit is controlled to block the voice signal of the transceiver. And control means for controlling the melody generating means to drive and transmit a predetermined sound.
