     The paper discusses the main advantages and disadvantages of using a
 modern PABX for mixed speech and data traffic.  It comes to the conclusion
 that with the currently available technology it is not economic to use
 such an exchange for extensive data traffic and the paper goes on to look at
 future trends in this area in
 particular the use of PABX/LAN Gateways to ease connection problems.
