Abstract

본 발명은 전화기와 국선 선로의 연결 상태를 발신 초기에 검출하여 사용자에게 알릴 수 있는 전화기의 국선연결 체크 방법에 관한 것으로, 이를 위하여, 통화 시도시에 국선 선로와 전화기의 연결 상태를 체크하기 위한 방법에 있어서, 사용자가 발신을 위해 송수화기를 들면 후크 오프 상태임을 마이컴에게 인식시키기 위한 과정과, 상기 마이컴의 제어에 의해 국선 선로에 전화기가 제대로 루프되었는지를 검출하는 과정과, 루프가 되지 않았을 경우 사용자에게 이를 인식시키기 위하여 스피커를 통하여 에러톤을 발생하는 과정을 포함하는 전화기의 국선 연결 체크 방법을 제공함으로서, 전화 불통시에 사용자에게 전화기와 국선 선로의 연결이 불량하다는 것을 알려 보다 편리한 서비스를 제공하기 위한 것이다.The present invention relates to a method for checking a trunk line connection of a telephone that can detect a connection state between a telephone line and a trunk line at an early stage of transmission and notify a user. To this end, the present invention relates to a method for checking a connection state between a trunk line and a telephone line when a call is attempted. The process for recognizing the microcomputer that the user is in a hook-off state when the user lifts the handset for transmission, and the process of detecting whether the telephone is properly looped on the trunk line by the control of the microcomputer, and if the user does not loop, By providing a method for checking the trunk line connection of a telephone including a process of generating an error tone through a speaker for recognizing, it is to provide a more convenient service by informing the user that the connection between the telephone line and the trunk line is poor when a telephone is not available. .
