Not all PTTs are so anti-change. Several years ago Telecom Australia
announced Austpac, a datagram service to be charged by the octet. Don't
know if it took off though.

Analog to digital converters and digital switching technology offer
unification of voice and data handling.  A generation of managers used
to SxS or crossbar technology may resent digital. Then again upgrading
to digital while maintaining compatibility is not an easy job.
