Abstract
A broadband service communication system using an MV cable for conveying RF signals in a network segment, which includes a distribution center (PLT controller) and a plurality of power line telecommunication (PLT) stations. The PLT controller has a distribution modem for conveying downstream and upstream RF signals to and from the PLT stations through the MV cable via couplers. Each PLT station has a modem for conveying the downstream and upstream RF signals via couplers and for conveying media signals to one or more customer premises equipment (CPE) via, e.g. wireless links. The PLT controller controls each PLT station regarding upstream communications transfer of all downstream communications and also controls. The PLT controller can be connected via a router to a WAN to convey media signals to and from the WAN. Repeaters and interlinks are used to join multiple network segments.
