Abstract

본 발명은 무선전화기의 모뎀 자동선택 시스템에 관한 것으로, 일반적인 전화기/모뎀 선택시스템에 있어서, 모뎀을 사용하기 위해서는 스위칭시스템을 통해 항상 전화라인과 접속하여 만이 모뎀사용이 가능한 문제점이 있었다.The present invention relates to a modem automatic selection system for a wireless telephone. In a general telephone / modem selection system, there is a problem that a modem can be used only by always connecting to a telephone line through a switching system in order to use a modem.

이를 보완하기 위한 본 발명은 모뎀모드시 무선전화기의 고정장치로 부터 송출된 고주파신호를 휴대장치에서 수신, 분석하여 일정횟수의 링신호가 수신되면 스위칭부를 자동으로 모뎀측으로 절환한후 링신호를 모뎀에 전송하고 또한 모뎀키이가 입력되면 고정장치에서 송출된 링데이타의 횟수에 관계없이 스위칭부를 모뎀축으로 절환하여 타모뎀과 무선으로 데이타 전송이 가능토록하고, 전화모드시에는 스위칭부를 송, 수화기로 절환하여 전화통화를 할수 있도록 한 것이다.The present invention to compensate for this is to receive and analyze the high frequency signal transmitted from the fixed device of the radiotelephone in the modem mode in the portable device, when a certain number of ring signals are received, the switching unit automatically switches to the modem side and then the ring signal to the modem When the modem key is input and the modem key is input, regardless of the number of ring data transmitted from the fixed device, the switching unit is switched to the modem axis so that data can be transmitted wirelessly with another modem. Switched to make a phone call.
