모뎀의 호출모드에서 마이콤(20)의 제어에 의해 통화로를 형성하고 다이얼림 제어하며 비지톤을 체크하기 위한 명령어에 대한 입력인가를 체크하는 제1과정과 비지상태 체킹용 명령어가 입력되었을 때 다이얼모드를 세트하고 입력펄스를 조성회로(n) 카운트할때까지 비지 상태임이 감지되어야만 비지상태로 인식할수 있으므로 소정회로(n)를 카운터 레지스터로 전송 카운팅 모드 세트하는 제2과정과, 다이얼링후 교환기로 부터 입력되는 신호로부터 비지상태에 해당하는 시호의 펄스폭을 체크하는 제3과정과, 제2과정의 설정 카운트 값(n)을 감소시켜 설정값이 제로이면 비지 상태음으로 감지하여 감지 상태를 사용자가 인식할수 있도록 출력하는 제4과정을 포함하여 이루어진 것을 특징으로 하는 비지 톤 에너지 감지방법.In the call mode of the modem, the first process of forming a call path under the control of the microcomputer 20, dialing control, and checking whether the input is input to a command for checking a busy tone, and a dial when a command for busy state checking is input. After the mode is set and the input pulse is detected until the input pulse is counted, the busy state can be recognized as the busy state. Therefore, the second process of setting the counting mode to transfer the predetermined circuit n to the counter register is performed. The third process of checking the pulse width of the time signal corresponding to the busy state from the signal input from the second signal, and the set count value (n) of the second process is reduced to detect the busy state by detecting the busy state sound when the set value is zero. Busy tone energy detection method comprising a fourth process for outputting so as to recognize. 모뎀 및 전화선을 이용한 컴퓨터 주변기기에서 비지 톤 감지회로에 있어서 모뎀 단말기에 RS-23C규격에 따른 연결로 데이터 단말장치를 접속할 수 있는 접속(10)와, 상기 접속부(10)의 입력데이타에 따라 프로그램을 처리하여 모뎀기능을 수행하도록 제어하여 다이얼 톤을 감지하고 다이얼링 송출을 제어하는 마이콤부(20)와, 마이컴부(20)의 제어에 따라 변복조 기능을 가지며 모뎀 전용회로로서 교환기로 부터 발생되는 통화중음을 감지하여 에너지 감지단이 감지신호를 상기 마이컴부(20)에 제공하는 모뎀(30)과, 송수신시 모뎀으로 부터 입출력되는 데이터의 전송통로를 제어하고 데이타를 버퍼링하는 하이브리드부(40)와, 마이컴의 제어에 따라 송수신시 릴레이를 제어하여 제어하는 수신되는 톤신호의 흐름을 제어하고 송수신 데이터를 트랜스에 의해 임피던스 매칭하는 릴레이부(50)와 릴레이부로 부터의 상대편 모뎀과 전화선(Tip, Ring)을 통해 접속되어지는 데이터 억세스 어렌지먼트(60)를 포함하여 구성된 것을 특징으로 하는 비지 톤 에너지 감지장치.In a busy tone detection circuit in a computer peripheral device using a modem and a telephone line, a connection 10 for connecting a data terminal device to a modem terminal by connection according to the RS-23C standard and a program according to the input data of the connection unit 10 are performed. It handles to perform modem function to detect the dial tone and control the dialing transmission, and has the modulation and demodulation function under the control of the microcomputer unit 20. Energy detection stage Modem 30 for providing the detection signal to the microcomputer 20, a hybrid unit 40 for controlling the transmission path of the data input and output from the modem at the time of transmission and reception and buffering the data, and the transmission and reception under the control of the microcomputer Control the flow of the received tone signal by controlling the relay at the time of the relay and the data to be connected through the relay unit 50 and the other modem and the telephone line (Tip, Ring) from the relay unit for impedance matching of the transmission and reception data by the transformer Busy tone energy sensing device comprising an access arrangement (60). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
