[comp.dcom.telecom] When to Use / Not Use the '1'

mvanbusk@bcm1a05.attmail.com (03/09/91)

With all of the questions recently on when to use 1 for dialing I have
a new twist to add. Why is it necessary to dial 1 for local calls? The
city I live in is served by Illinois Bell and GTE. When calling local
from the IBT Company to the GTE Company (815-398-xxxx to 815-874-xxxx)
a 1 must be dialed first. However, if calling from 874-xxxx to
398-xxxx 1 is not needed.  Any explanations? Do any other cities
served by two LEC's require this type of dialing?

[Moderator's Note: From IBT's Chicago-Newcastle CO to Centel's
Chicago-Newcastle numbers, only seven digits are dialed, and it is a
local, untimed call. From IBT or Centel in Chicago to IBT or Centel in
the suburbs -- even if is across the street (or the shop next door in
the mall, in one case along Harlem Avenue) then 1-708 or 1-312 must be
prepended.   PAT]
