1. A baud clock driven data multiplexer comprising:

  • means for receiving data from at least a first data terminal equipment (DTE) port;

    means for data multiplexing said received data to form a first data stream wherein said first data stream is a sum of data streams of at least the first DTE port and is carried by a first communication channel to a data demultiplexer that demultiplexes said first data stream back to its original constituent data;

    quality-responsive diverting means, responsive to a signal that indicates that a quality of the first communication channel that carries the sum of the data streams of at least the first DTE port has become reduced such that said channel carries less data than said sum of data streams, for automatically diverting part, but not all, of the received data to a second data stream carried by a second channel so that said first and second data streams together support transmission of said received data over said first and second communication channels,where said diverting means establishes communications over said second communication channel only upon said quality of the first communication channel becoming reduced such that said first communication channel is unable to carry all of said first data stream.
