    摘要: 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.

    摘要: Methods and apparatus are provided for interconnecting first and second information buses each having a plurality of data lines. A pair of unidirectional information paths each consisting of twisted-pair cables are provided, along with a 25 MHz strobe. Information is transmitted using pseudo-ECL signal levels. A pair of clock differential receiver circuits is provided such that data is transferred over the interconnect bus using both the rising and falling edges of the transmitted clock signal and transferred from one bus to another at a rate of 50 MHz.
