Even though I think it will happen earlier than 1994, I agree with Mr.
Lewis.  And, yes indeed, "the audio leased line department will go out
of business in a hurry!"  When a user can dial up a full T1 circuit
for 10 minutes *and be billed for only 10 minutes use*, it's going to
be hard to justify leasing a 19.2 kb/s connection 24 hours a day, 7
days a week.
  
ISDN was a warm-up.  *Broadband* ISDN is really going to change the world.
