1. A communications apparatus, comprising:

  • a first queuing means for receiving information packets associated with low bandwidth calls;

    a second queuing means for receiving information packets associated with high bandwidth delay sensitive calls;

    a third queuing means for receiving information packets associated with high bandwidth delay insensitive calls;

    a multiplexing means for sequentially and cyclically drawing a predetermined number of information packets during successive service cycle time periods from each of the first, second, and third queuing means and combining those packets on a single output line; and

    a variable scheduling means, associated with the third queuing means, for providing a plurality of selectable scheduling schemes for completing the high bandwidth delay insensitive calls.
