1. An apparatus for transmitting isochronous information over an asynchronous network, comprising:

  • a memory for receiving a plurality of isochronous data words for a plurality of isochronous channels, each said isochronous data word being associated with a predetermined isochronous channel, said isochronous data words for a said isochronous channel being generated at a sampling rate predetermined for that channel, each said isochronous channel having a predetermined maximum acceptable delay time;

    an aggregator for receiving selected ones of said isochronous data words of said plurality of isochronous data words from said memory and aggregating said selected ones of said isochronous data words to provide an aggregation of selected isochronous data words for selected isochronous channels;

    a controller for, at a rate determined by the least said predetermined maximum delay time, repeatedly selecting channels of said plurality of isochronous channels, selecting said selected ones of said isochronous data words of said plurality of isochronous data words for each selected isochronous channel, said number of data words for a selected channel having a maximum determined by said sampling rate and said maximum acceptable delay time for that selected channel, causing said aggregator to receive and aggregate, and sending an instruction to assemble a data transmission packet;

    a multiplexer responsive to said instruction for assembling a said data transmission packet from each said aggregation; and

    a transmitter for transmitting each said data transmission packet over said asynchronous network.
