Abstract

본 발명은 DTMF감지장치를 이용하여 D.D.D사용을 제어하는 간이 교환시스템의 D.D.D제어방법 및 장치에 관한 것으로, 전화장치로부터의 통화신호를 감쇄수단을 통해 DTMF감지부에 인가하는 것을 특징으로 한다. 따라서, 본 발명에 의한 이용자의 음성에 포함되어 있는 DTMF성분이 감쇄수단에 의해 제기되어 음성에 포함된 DTMF성분에 의해 D.D.D제어동작이 발생하는 것이 방지되게 된다.The present invention relates to a D.D.D control method and apparatus of a simple exchange system for controlling the use of D.D.D by using a DTMF detection device, characterized in that the call signal from the telephone apparatus is applied to the DTMF detection unit through attenuating means. Therefore, the DTMF component contained in the user's voice according to the present invention is brought up by the attenuation means to prevent the D.D.D control operation from being generated by the DTMF component included in the voice.
