Abstract

본 발명은 전화기의 다이얼 제어장치에 관한 것으로, 특히 별도의 DTMF(Dual Tome Multi Frequency)발생회로나 펄스 다이얼용 릴레이를 사용하지 않고도, 하나의 일반 다이얼러 회로를 중앙처리장치가 제어하여 다이얼을 송출할 수 있도록 함을 목적으로 한 전화기의 다이얼 제어장치에 관한 것으로써, 이러한 본 발명의 목적은 중앙처리장치로부터 출력된 코드데이타, 제어신호 및 스트로브신호에 따라 크로스포인트 스위치를 제어하여 다이얼버튼 입력수단의 버튼출력신호를 제어하는 크로스포인트스위치 제어수단과, 상기 크로스포인트스위치 제어수단의 제어에 따라 상기 다이얼버튼입력수단으로부터 출력된 다이얼에 해당하는 DTMF신호 및 다이얼펄스를 발생하여 국선으로 송출하는 다이얼신호출력수단으로 구성함으로써 달성된다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dial control apparatus for a telephone, and in particular, a central processing unit controls a general dialer circuit to transmit a dial without using a separate DTMF (Dual Tome Multi Frequency) generating circuit or a pulse dial relay. The present invention relates to a dial control apparatus for a telephone for the purpose of controlling the crosspoint switch according to code data, a control signal and a strobe signal output from a central processing unit. Cross point switch control means for controlling a button output signal, and a DTMF signal and dial pulse corresponding to a dial outputted from the dial button input means according to the control of the cross point switch control means to generate a dial signal output to a trunk line By means of means.
