1. A time division multiplexer for multiplexing data from a plurality of channels, comprising:

  • a) a high speed bus having a first data rate;

    b) a means for synchronizing;

    c) a system communication manager means coupled to said high speed bus, and including intelligent processing means for generating a data frame;

    d) a plurality of processors, each having a memory which stores said data frame, each one of said processors being coupled between a respective one of said channels and said high speed bus, and each of said processors being synchronized by said means for synchronizing, wherein said system communication manager means for transmitting said data frame to said plurality of processors over said high speed bus at predetermined times and at an effective second data rate slower than said first data rate, whereupon each of said processors stores said data frame in its memory, and said system communication manager means for causing said means for synchronizing to generate a synch signal which synchronizes said processors, wherein,said data frame comprises a first sequence of instructions for said plurality of processors coupled to said channels, which instructions instruct said processors as to when to place data on said high speed bus, and each of said plurality of processors synchronously and simultaneously runs said data frame and places data on said high speed bus according to said instructions of said data frame when the channel with which a particular processor is associated is indicated by said data frame.
