Abstract

본 발명은 송신자측에서 키보드를 사용하여 문자를 입력하면 입력된 문자를 송신자측 전화기에 부착된 액정 표시장치 상에 출력하는 동시에, 각각의 문자에 대응하는 DTMF 신호로 바꾼 다음, DTMF 신호를 전화선을 통하여 전송하면 수신자측에서는 전송된 DTMF 신호를 수신자측 전화기에 부착된 액정 표시장치상에 다시 문자로 출력함으로써, 전화선을 통한 문자의 송수신이 가능하도록 구성한 문자 전송 전화기에 관한 기술이다.According to the present invention, when a character is input using a keyboard at the sender side, the character is output on a liquid crystal display attached to the telephone at the sender side, and at the same time, the DTMF signal corresponding to each character is converted into a DTMF signal. When the transmission is performed through the receiver, the receiver transmits the transmitted DTMF signal to the liquid crystal display attached to the receiver's telephone, and then transmits and receives the character through the telephone line.
