Abstract

전화회선(40)의 유휴시간을 이용한 통신장치를 전제로 한다.It is assumed that the communication device using the idle time of the telephone line 40.

그리고, 여기에 대응해서, 송신쪽에는, 잔송신호를 디지틀신호로 출력시키는 복수의 송신수단(12),(32), 이들 전송신호를 각각 아나로그화 하는 제1모뎀((15) 또는 (35)), 복수의 전송신호를 다중화 하여 전화회선(40)으로 출력시키는 다중화수단(C5),(U5)을 설치한다.Correspondingly, the transmission side includes a plurality of transmission means 12, 32 for outputting a residual signal as a digital signal, and a first modem 15 or 35 for analogizing these transmission signals, respectively. ), And multiplexing means C5 and U5 for multiplexing a plurality of transmission signals and outputting them to the telephone line 40.

그리고, 수신쪽에는, 상기한 다중화신호를 복수의 전송선으로 분할하는 분할수단(C6),(U6) 이들 전송신호를 각각 디지틀화하는 제2모뎀(15) 또는 (35), 각 전송신호에 대응해서 작동되는 수신수단(13),(33)등을 설치한다.On the receiving side, dividing means (C6) for dividing the multiplexed signal into a plurality of transmission lines (U6), and a second modem (15) or (35) for digitizing these transmission signals, respectively, corresponding to each transmission signal. Receiving means (13), (33) and the like are installed.

이렇게 하므로써, 전송신호는 디지틀 신호로 발생되어, 모뎀(15) 또는 (35)에서 아나로그 신호로 변환되지만, 전송속도록 비교적 낮은 속도로 설정하면, 모뎀출력의 단계에서는 점유대역이 좁아지므로, 전화회선(40)의 사용 대역을 유용하게 사용할 수 있으며, 따라서, 1회선의 전화회선(70)으로 복수의 전송신호를 동시에 전송할 수 있게 되어 정보전달을 확대할 수 있다. 그러므로, 전화회선(47)의 사용효율을 높이면서 전화회선(40)의 유휴시간을 이용한 통신에서 복수의 전송신호를 1회선의 전화회선(40)을 사용하여 동시에, 또, 혼신없이 전송할 수 있으므로, 정보전달의 확대화를 도모할 수 있게 된다.In this way, the transmission signal is generated as a digital signal and converted into an analog signal in the modem 15 or 35. However, if the transmission signal is set at a relatively low speed for transmission speed, the occupied band becomes narrow in the modem output phase. The use band of the line 40 can be usefully used, and therefore, it is possible to simultaneously transmit a plurality of transmission signals to the telephone line 70 of one line, thereby expanding information transmission. Therefore, in the communication using the idle time of the telephone line 40 while improving the use efficiency of the telephone line 47, a plurality of transmission signals can be transmitted simultaneously using the telephone line 40 of one line and without interference. As a result, information transmission can be expanded.

다중화의 한 방법으로, 전송신호를 주파수의 축을 따라 배열하는 것을 제안하고 있다.As a method of multiplexing, it is proposed to arrange transmission signals along an axis of frequency.

또, 다른 방법으로는, 전송신호를 시간의 축을 따라서 배열하는 것을 제안하고 있다.As another method, it is proposed to arrange the transmission signals along the time axis.
