Wait for Broadband ISDN.  SONET (Synchronous Optical NETwork) layer 1,
plus ATM (Asynchronous Transfer Mode) layer 2, plus the appropriate
definition of bearer capabilities, signaling, user-network interfaces,
and all that stuff (yet to be done...), gives you dynamic baodwidth
allocation.

Not until at least 1994, tho.  And even then only in very limited
deployment.  Not the kind of thing you'll order when you move into
that new apartment.
