본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 본 발명에 따른 블럭도.2 is a block diagram according to the present invention.

Claims (1)

다수의 휴대장치를 갖는 무선전화기의 고정장치에 있어서, 소정 제1핸드셋과 교신할시 소정 제1제어신호를 받아 그에 오디오 신호를 변조출력하거나 상기 제1핸드셑의 송신신호를 받아 복조하여 출력하는 제1송수신 모듈(TR1)과, 상기 제1핸드셑과 소정 제K핸드셑간에 상호 교신할시 소정 제2제어신호를 받아 상기 제1핸드셑에서 수신한 신호를 제K핸드셑에 변조 송신하고 제K핸드셑에서 송신한 신호를 복조하여 출력하는 제2송수신 모듈(TR2)과, 상기 제1송수신 모듈(TR1)의 변조출력을 받아 소정 제2제어신호에 의개 국선라인에 전달하거나 또는 상기 제2송수신 모듈(TR2)로 전달하는 제1스위칭수단(SW1)과, 상기 제2송수신 모듈(TR2)의 복조출력을 상기 제2제어신호에 의해 상기 제1송수신 모듈(TR1)로 전달하는 제2스위칭수단(SW2)과, 상기 제1송수신 모듈(TR1)을 제어하기 위한 제1제어신호와 상기 제2송수신 모듈(TR2)을 제어하기 위한 제2제어신호 및 상기 제1,2스위칭 수단(SW1,SW2)을 제어하기 위한 제3제어신호를 생성 출력하여 핸드셑과 핸드셑이 상호 교신할 수 있도록 각부를 제어하는 제어부(CT)로 구성함을 특징으로 하는 휴대장치끼리 통화가 가능한 무선전화기.A fixed device of a radiotelephone having a plurality of portable devices, wherein when communicating with a predetermined first handset, receiving a predetermined first control signal and modulating and outputting an audio signal or receiving and demodulating and outputting a transmission signal of the first handset. When communicating with the first transmission / reception module TR1 and the first hand and the predetermined K hand, receive a predetermined second control signal and modulate and transmit the signal received from the first hand to the K hand. The second transmission / reception module TR2 for demodulating and outputting the signal transmitted from the K-th handset and the modulated output of the first transmission / reception module TR1 are transmitted to the local trunk line by a predetermined second control signal, or A first switching means SW1 for transmitting to the second transmission / reception module TR2 and a second demodulation output of the second transmission / reception module TR2 to the first transmission / reception module TR1 by the second control signal. Switching means (SW2) and the first transmission and reception module (TR1) Generate and output a first control signal for controlling the second control signal, a second control signal for controlling the second transmission / reception module TR2, and a third control signal for controlling the first and second switching means SW1 and SW2. A wireless telephone capable of talking between portable devices, comprising a control unit (CT) for controlling each unit so that the hand and hand can communicate with each other. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
