Abstract

본 발명은 원래의 전화기에 병렬로 연결된 타전화기의 다이얼링을 억제하기에 적합한 전화기의 다이얼링 제어 장치 및 그 방법에 관한 것으로, 종래의 기술에 있어서는 사용자의 필요에 의해 병렬로 연결된 타전화기를 수신만 가능하도록 하고자 할 경우 이를 제어하기가 곤란하였으나, 본 발명에서는 타전화기 억제 모드에 따라 전화 선로(30)의 전압 레벨을 조절함으로써 병렬로 연결된 타전화기의 다이얼링을 용이하게 억제할 수 있으므로 상기 결점을 해결할 수 있는 것이다.The present invention relates to an apparatus for dialing control of a telephone and a method thereof suitable for suppressing dialing of another telephone connected in parallel to the original telephone. In the related art, only another telephone connected in parallel can be received by a user's needs. Although it is difficult to control this, in the present invention, by adjusting the voltage level of the telephone line 30 according to the other telephone suppression mode, it is possible to easily suppress the dialing of other telephones connected in parallel to solve the above-mentioned drawback. It is.
