Abstract

본 발명은 키패드로 누른 전화번호를 다이얼링을 행하는 마이컴과, 사용자가 누른 전화번호에 대한 DTMF 신호를 발생하는 DTMF제너레이터와, 전화번호를 다이얼링한 후 코올 프로그레싱을 행하는 톤디텍트IC와, 전화라인으로 들어오는 신호를 정류하는 브릿지다이오드와, 마이컴에 의해 온/오프기능을 갖는 스위치와, 통화상태음을 발생시키는 음발생부로 구성하여 전화번호가 통화중일 때 다시 다음 전화번호를 걸어 전화 통화상태를 재 확인해야 하는 사용자의 번거로움과 불편함을 해소시킬 수 있게 한 것이다.A DTMF generator for generating a DTMF signal for a telephone number pressed by a user, a tone detection IC for performing a COOL progression after dialing a telephone number, a telephone line A bridge diode for rectifying an incoming signal, a switch having an on / off function by a microcomputer, and a tone generator for generating a tone of a call tone so that when the telephone number is busy, the next telephone number is re- Thereby making it possible to eliminate the hassle and inconvenience of the user.
