Abstract

본 발명은 모뎀 내장형 전화기의 입력신호 절환장치에 관한 것으로서. 종래의 모뎀 내장형 전화기는 음성통화 및 데이타 송/수신시 번번히 PC에 저장된 별도의 응용프로그램을 실행시켜야만 하기때문에 번거로우며, 또한 음성통화 및 데이타 송/수신시 매번 응용 프로그램 상에서 후크 스위치 (HSW)를 온/오프 시켜야만 하는 문제점이 있었다. 따라서, 상기 문제점을 해결하기 위한 본 발명은 후크 스위치를 손쉽게 온/오프 제어할 수 있도록 하고, 또한 입력신호를 모뎀카드 또는 통화수단으로 손쉽게 절환할 수 있도록 하여 별도의 전화기를 외부에 설치하지 않고도 모뎀에 접속된 헤드 셋 또는 핸드 셋을 이용하여 음성통화를 할 수 있도록 한 모뎀 내장형 전화기의 입력신호 절환 장치이다.The present invention relates to an input signal switching device of a modem embedded phone. Conventional modem built-in phones are cumbersome because they often have to run separate applications stored on the PC during voice calls and data transmission / reception, and also turn on the hook switch (HSW) on each application during voice calls and data transmission / reception. There was a problem that had to be turned on / off. Therefore, the present invention for solving the above problems can be easily on / off control of the hook switch, and also to be able to easily switch the input signal to the modem card or call means without having to install a separate telephone outside It is an input signal switching device of a modem-embedded telephone that allows voice calls using a headset or handset connected to the modem.
