Claims (1)

모뎀을 이용한 통신 방법에 있어서, 선로의 신호 레벨을 검출하는 제1과정과, 턴온레벨과 턴오프레벨을 검출된 신호레벨보다 제1소정 레벨만큼 높이 설정하여 상기 모뎀의 수신 감도를 설정하는 제2과정과, 유효데이타 수신 여부를 체크하는 제3과정과, 유효데이타 수신시 턴온레벨과 턴오프레벨을 현재 수신신호레벨보다 제2소정 레벨만큼 낮게 설정하고 이에 따라 상기 모뎀의 수신 감도를 재설정하여 수신하는 제4과정과, 유효데이타 수신상태가 아닐시 현재의 수신 신호가 턴오프레벨보다 제3소정 레벨만큼 낮은 레벨보다 작은지 체크하여 작을시 턴오프레벨과 턴온레벨을 현재의 수신 신호 레벨보다 제4소정레벨만큼 증가 시키고 이에 따라 상기 모뎀의 수신 감도를 재설정하여 수신하는 제5과정으로 이루어짐을 특징으로 하는 모뎀 수신 감도 가변 통신 방법.A communication method using a modem, comprising: a first process of detecting a signal level of a line, and a second sensitivity of setting a reception sensitivity of the modem by setting a turn-on level and a turn-off level higher than a detected signal level by a first predetermined level And a third step of checking whether or not valid data is received; and setting the turn-on level and the turn-off level lower than the current reception signal level by a second predetermined level when valid data is received, and reset the reception sensitivity of the modem accordingly. The fourth process and if the valid data is not received, checks whether the current received signal is lower than the turn-off level by a third predetermined level, and when it is small, the turn-off level and the turn-on level are lower than the current received signal level. And a fifth process of increasing by a predetermined level and resetting the reception sensitivity of the modem accordingly. Communication method. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
