摘要: A premise signal conditioning device is provided that can be inserted into a transmission line of CATV system on user. The includes at least first diplexer set, each set including supplier side and creating return path for an upstream bandwidth forward downstream there between. further detector configured to measure level signals present in segment frequencies between the bandwidth. switch controller alter width from second response exceeding predetermined threshold level.
