Abstract

본 발명은 전화기에 관한 것으로, 일반전화기에 모듈과 잭을 이용하여 병렬로 접속하며 다수의 전화번호를 저장한 후 단축 다이얼링을 통해 상대방과 통화로를 연결하여 주도록 한 것이다.The present invention relates to a telephone, which is connected to a parallel telephone using a module and a jack to a general telephone, and stores a plurality of telephone numbers and then connects the call path with the other party through speed dialing.

본 발명은 자체의 메모리 선택 키를 이용하여 상대방 전화번호를 저장하여 일반전화기의 송수화 수단이 온훅인 상태에서 단축 다이얼링시 국선을 점유하여 저장된 전하번호를 송출한 후 일반 전화기의 송수화 수단이 오프 훅 되면 선로의 전압 변동을 검출하여 국선 점유를 해제하므로 사용에 편리성을 제공한다.The present invention stores the other party's telephone number using its own memory selection key to transmit the stored charge number by occupying the trunk line when speed dialing while the handset means of the general telephone is on hook, and then the handset means of the ordinary telephone is turned off. When hooked, it detects voltage fluctuations in the line and releases the occupation of the trunk line, providing convenience for use.
