Abstract

본 발명은 공중전화기에 있어서 통화 이전까지를 온후크 상태로 다이얼링 하고 이후 외부 스피커를 통해 착신을 인지하여 온후크시에도 다이얼링을 하고자 한 공중전화기의 온후크시 다이얼링 방법에 관한 것으로, 이러한 본 발명의 목적은 온후크 상태에서 스피커 버튼이 눌러지게 되면 표시소자를 구동시키고 송수화기가 돌려질 때까지 수화기의 출력신호를 외부 스피커측으로 절환시키는 제1과정과, 투입된 요금이 기본 통화요금 이상이면 통화루프를 연결시키고 가입자선을 검색하는 제2과정과, 상기 제2과정에서 가입자선이 통화중 또는 부재중일 경우 스피커 버튼이 다시 눌러지면 상기 표시소자를 오프시키고 통화루프를 오픈하여 처음 상태로 리턴하는 제3과정과, 상기 제2과정에서 상대방 응답이 있게되면 외부 스피커의 출력신호를 송수화기로 절환시켜 통화를 가능하게 하는 제4과정을 실행시킴으로써 달성된다.The present invention relates to a method for dialing on hook of a public telephone, which is to be dialed even when on a hook by dialing before a call in a public telephone before the call and recognizing an incoming call through an external speaker. In the on-hook state, when the speaker button is pressed, the display device is driven and the output signal of the handset is switched to the external speaker until the handset is turned on. A second process of searching for a subscriber line; and a third process of turning off the display element, opening the call loop and returning to the initial state when the speaker button is pressed again when the subscriber line is busy or absent in the second process; In response to the other party's response in the second step, the handset output signal of the external speaker This is accomplished by carrying out a fourth process of switching over to enable the call.
