Note here that if you use a stat mux (statistical multiplexer)
the aggregate input can actually exceed the speed of the link.
For example you could put 10 2400 kb lines over a single 9.6
link.  Or for that matter multiple 9.6 lines muxed over a single
9.6 link.  Of course this only works for such things as terminal
traffic where the full bandwidth is rarely occupied.
