1. A network interface for multiplexing and demultiplexing isochronous and nonisochronous data streams in asynchronous transfer mode based communications networks, which comprises:

  • a multiplexer portion including means for receiving isochronous and nonisochronous data from independent processors and for generating ATM cells incorporating said data, and means for multiplexing said ATM cells onto a single logical connection associated with said asynchronous transfer mode based communication network; and

    a demultiplexer portion including means for receiving isochronous and nonisochronous ATM cells from said single logical connection and for demultiplexing said isochronous and nonisochronous ATM cells to extract isochronous data from said isochronous ATM cells and nonisochronous data from said nonisochronous ATM cells, and means for storing said extracted isochronous and nonisochronous data for subsequent transfer to independent processors.
