Abstract

본 발명은 케이블TV 망에서 기존의 네트워크 매니저먼트 시스템에 선로 절단 감지부를 추가한 것으로, 종래의 경보체계의 시설 및 유지에 대한 많은 비용 부담과 잦은 고장 등의 문제를 감안하여, 케이블TV망에서 기존의 네트워크 매니저먼트 시스템에 선로 절단 감지부를 추가하여 고의 또는 기타 여러가지 사고에 의한 선로 절단 신호를 감지하여 망 관리를 용이하게 하고, 외부 침입으로부터 가입자를 보호할 수있게 한것이다.The present invention is to add a line cut detection unit to the existing network management system in the cable TV network, in consideration of the problems such as a lot of cost and frequent failure for the installation and maintenance of the conventional alarm system, existing in the cable TV network The line cut detection unit was added to the network management system in order to detect the line cut signal caused by intentional or various accidents to facilitate network management and to protect the subscriber from external intrusion.
