I believe Northern Telecom phone switches already support digital
modems.  (Northern Telecom supplies telecommunications hardware to
both MCI and US Sprint).  In the long-distance telecommuncations
industry, most everything is already all-digital.  The problem is
essentially the local service and the wire in your house.

Ah, they do, especially if one phone company has it and another doesn't.
The problem is that it's an *extremely* expensive proposition that
involves replacing all the wires that the phone network consists of
with fiber.  That takes a _long_ time, and _alot_ of money.
