I'm using 16 channel multiplexors to connect users at a remote location
to our HP3000.  The multiplexors have an aggregate max burst rate of
115,200bps.  I have 2 printers and 4 terminals all communicating at 9600
bps.  My problem is that I can only have 3 of the terminals logged on at
one time - any 3 of the 4 but not 4 at one time.  The phone line is a
dedicated 9600 baud line.  On the surface it appears that the phone line
is the limiting factor.  My understanding is that the muliplexor is
sending individaul packets of information.  I would guess that a faster
line would therefore increase total throughput and allow me to add more
terminals - adding more terminals and printers is my ultimate goal.
Am I headed in the right direction or missing the whole concept?

Any help would be appreciated,
