[comp.dcom.telecom] First to Acknowledge the 1+?

I read in the Phoenix, Arizona call guide of Feb. 1990 that the
1+602+7D for toll calls within Arizona was to go into effect July 1,
1990.  It goes on to say "It will also allow customers to continue to
know on which calls a charge applies."

(To summarize, for those areas needing N0X/N1X prefixes:

Toll calls within area must be 7D or 1+NPA+7D; can no longer use 1+7D.
Toll calls to other areas must be 1+NPA+7D; can no longer use NPA+7D.)
