What are the alternatives to the following: My shop runs a data
network over multi-drop four-wire leased lines to ~80 branch locations
stragetically sprinkled over half of our state, Ohio.  The lines run
SDLC or Bisync and carry IBM 3270 terminal traffic.  There are 4800-
and 9600-bps circuits.  The lines are utilized only during normal
business hours.  They cost a lot.
 
Is there a good way to have switched lines dial into a bridge to
create a multi-drop image?  Is X.25 a viable alternative?  Are there
new services such as ISDN or Virtual Private Data Networks or anything
else that could substitute?
