Claims (1)

단말장치(10)와 핸들러(20)에 전화단자를 첨가하여 전화코드로 연결통신시 상기 전화단자내 신호검출부(21)의 출력루프신호(SL)가 하이인 상태에서 훅상태 검출부(22)의 훅상태신호(SH)가 하이이면 훅-오프 상태임을 나타내고, 상기 신호(SH)가 하이가 아니면 링검출부(23)의 링신호(SR)가 하이이거나 아닐 경우에 상기 링신호를 일정시간 체크시 구형파 발생시 링상태임을 표시하는 단계와, 상기 루프신호(SL)가 하이가 아니면 릴레이를 온하여 훅-오프 검출신호(ST)가 하이거나 아닐경우 링신호를 일정시간 체크하여 구형파 검출시 링상태이고 검출되지 않으면 처음으로 돌아가는 단계와, 상기 훅-오프 검출신호(ST)가 하이이고, 링신호(SR)가 하이가 아니면 링신호를 여러번 체크하여 구형파 검출시엔 링상태를 검출되지 않을 경우엔 훅-오프 상태임을 나타내는 단계로 진행됨을 특징으로 하는 핸들러의 전화선 상태 체크방법.Hook state detection unit 22 in the state that the output loop signal (S L ) of the signal detection unit 21 in the telephone terminal is high when the telephone terminal is connected to the terminal device 10 and the handler 20 by the telephone cord. If the hook state signal S H of the signal is high, the hook-off state is indicated. If the signal S H is not high, the ring signal S R of the ring detection unit 23 is high or not. Displaying a ring state when a square wave occurs at a certain time check, and if the loop signal (S L ) is not high, the relay is turned on to check the ring signal for a predetermined time if the hook-off detection signal (S T ) is low or not. When the square wave is detected, if the ring state is not detected and returns to the beginning, and the hook-off detection signal S T is high and the ring signal S R is not high, the ring signal is checked several times. If is not detected, it is hook-off The telephone line status check method of the handler, characterized in that the step proceeds to the step. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
