Abstract

본 발명은 직류펄스로 제어되는 재래식 기계식 자동교환기에 의해 구축된 통신망에서 DTMF(Dual Tone multi Frequency) 톤에 따라 서비스가 제공되는 부가 서비스 시스템을 이용할 수 있게 다이얼 모드가 DP(Dial Pulse) 방식과 MFD(Multi Frequency Code) 방식으로 상호 전환되도록 된 팩시밀리에서의 다이얼 모드변환 방법 및 그 장치에 관한 것으로, 다이얼모드 변환 기능키를 구비한 키패드부; 장치 전반을 제어하는 것으로, 통화로가 설정된 상태에서 상기 키패드로부터 다이얼 모드변환을 위한 소정의 기능키가 눌려지면 다이얼이 초기의 DP모드에서 MFC모드로 전환되어 동작되도록 제어하는 제어부; 상기 제어부의 제어에 따라 DP 모드에서는 직류 루프전류회로를 숫자만큼 단속하여 다이얼 펄스 열을 출력하고 MFC모드에서는 고역 주파수군과 저역 주파수군에서 조합되어 만들어지는 DTMF 톤을 출력하는 톤 발생부 및; 상기 제어부가 소정의 특수키 입력에 따라 다이얼모드를 변환하도록 하는 동작 프로그램을 제공하는 프로그램 저장부를 구비하는 것을 특징을 한다.The present invention is characterized in that a dial mode is divided into a DP (Dial Pulse) mode and an MFD (Dual Mode) so that a supplementary service system provided according to a DTMF tone can be used in a communication network established by a conventional mechanical automatic exchanger controlled by a DC pulse. (Multi-Frequency Code) method and an apparatus thereof, the method comprising: a keypad unit having a dial mode conversion function key; A controller for controlling the entire apparatus to switch the dial from an initial DP mode to an MFC mode when a predetermined function key for dial mode conversion is pressed from the keypad in a state in which a call is established; A tone generator for outputting a dial pulse train by interrupting the DC loop current circuit by a number in the DP mode under the control of the control unit and outputting a DTMF tone to be combined with the high frequency group and the low frequency group in the MFC mode; And a program storage unit for providing an operation program for allowing the control unit to change the dial mode according to a predetermined special key input.
