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.

Communications system for providing broadband communications using a medium voltage cable of a power system

A programmable data communications device is provided to process multiple streams of data according to multiple protocols. The device is equipped with a co-processor including multiple, programmable processors allowing data to be operated on by multiple protocols. The programmable processors within the co-processor include extended instruction sets including instructions providing the operations of zero stuffing, CRC computation, partial compare, conditional move, and trie traversal. These instructions allow the processor(s) of the co-processor to more efficiently execute programs implementing data communications protocols. Since each processor is programmable, protocols standards which change may be accommodated. A network device equipped with the co-processor can handle multiple simultaneous streams of data and can implement multiple protocols on each data stream. The protocols can execute within the co-processor either independently of each other, or in conjunction with each other.
