Claims (2)
- 데이타출력시스템(110)과 모뎀(120)을 포함하는 방송국 송신장치(100)와, 상기 방송국 송신장치(100)로 부터의 데이타를 전송하는 선로상의 망증폭기(150)와, 상시망증폭기(150)를 통한 데이타를 수신하는 케이블-텔레비전 수신장치로 구성된 데이타통신 시스템에 있어서,상기 망증폭기(150)를 통한 데이타를 복조시키는 모뎀(310);상기 모뎀(310)으로부터의 데이타중 컴맨드에 불요데이타 포함 여부에 따른 소정 레벨을 가지는 잼(JAM)제어신호를 출력하고, 또한 잼(JAM)제어신호를 출력한 후에 불요데이타가 제거되지 않은 경우에는 경보구동 제어신호를 출력하는 마이크로컴퓨터(320);클럭신호를 발생시키는 클럭발생기(330);상기 마이크로컴퓨터(320)의 잼제어신호와 상기 클럭발생기(330)의 클럭신호를 논리합하여 출력하는 오아게이트(OR gate)(340);상기 오아게이트(OR gate)(340)의 출력과 상기 방송국 송신장치(100)내 데이타출력시스템(110)의 출력을 논리곱하여 상기 방송국 송신장치(100)내 모뎀(120)으로 출력하는 앤드게이트(AND gate)(350)를 구비함을 특징으로하는 통신망상의 불요데이타 제거장치.
- 제1항에 있어서,상기 마이크로컴퓨터(320)로부터 출력되는 경보구동 제어신호에 의해서 불요데이타 제거실패를 표시하는 경보장치(360)를 더 구비함을 특징으로하는 통신망상의 불요데이타 제거장치.
