Abstract

본 발명은 광 케이블 텔레비젼의 분배 장치에 관한 것으로, 분배 장치가 광 케이블 텔레비젼 시스템 전체가 리셋되는 경우 또는 분재 스위치를 제어해 주는 부분이 동작을 못하는 경우 특정한 채널이 자동으로 스위칭되도록 하는 광 케이블 텔레비젼 오류 채널 처리 장치에 관한 것으로서, 종래에는 케이블 텔레비젼 전체가 정전되었다가 복구되는 경우나, 유지보수를 위해 불가피하게 스위칭 제어부를 정지시키게 되는 경우, 서비스되고 있는 채널의 화면이 불안정하게 디스플레이되는데, 이때 서비스 중단 사유를 가입자에게 알려주지 못해 가입자의 불만이 컸던 문제점이 있었으므로, 본 발명에서는 케이블 텔레비젼 전체가 정전되었다가 복구되는 경우나, 유지보수를 위해 불가피하게 스위칭 제어부를 정지시키게 되는 경우, 현재 서비스되고 있는 채널의 중단 사유를 나타내는 특정 채널이 선택되도록 하는 장치를 제공하므로써 광 케이블 텔레비젼의 분배 장치의 상태에 따라 가입자에게 선택 채널의 상태를 알려줄 수 있게 되어 가입자들로 하여금 신뢰감을 줄 수 있게 되고, 또한 시스템 이상 발생시 즉각 대처할 수 있게 된다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distribution device for an optical cable television, wherein the distribution device causes an optical cable television error to be switched automatically when the entire optical cable television system is reset or when the part controlling the bonsai switch fails. The present invention relates to a channel processing apparatus. In the related art, when an entire cable television is restored after a power failure, or when the switching control unit is inevitably stopped for maintenance, the screen of a channel being serviced is displayed unstable. Since there was a problem that the subscriber was not satisfied with the reason for the subscriber's dissatisfaction, in the present invention, when the entire cable television is interrupted and restored, or when the switching control unit is inevitably stopped for maintenance, the present invention is currently in service. By providing a device that allows a particular channel to be selected indicating the reason for the interruption of the null, the subscriber can be informed of the state of the selected channel according to the state of the distribution device of the optical cable television, thereby providing the subscriber with confidence. When an abnormality occurs, you can immediately deal with it.
