[comp.dcom.telecom] dialling patterns

de@moscom.UUCP (Dave Esan) (10/28/87)

Over on rec.arts.tv there has been on ongoing discussion of a telephone
number that Denise Huxtable called on "A Different World".  Strangely,
to call Brooklyn she dialled, so some one claims, 01-212-nxx-xxxx. 

It has been noted that Brooklyn in is 718, and that 01 is the prefix to
call internationally using the operator.  However, the following message
arrived recently:

--  In Georgia, the state Denise's collage is located, you must dial
-- 1-area code-telephone number, to call a long distance number,  If
-- you need operator assistance you must dial 01-area code-number.
-- For internationl operator assistance you dial 00.

Does anyone know if this is true?  I had thought that the prefixes 1, 0, 011,
01, and 10, were universal in their usage, and now that DC has changed to
require 1+ dialling, universal in their need.

Furthermore, has anybody heard of dialling 0 for the intralata operator and 
00 for the interlata operator?

Thanks.

It is common to see both 00 and 01 used in different areas to
access a long distance carrier for either operator or direct
calls.

The 1+ dialling requirement you find in DC and a couple of years
ago required in other states is so that you can start having 
local exchanges that look like area codes: 416, for example.
The switching office can no longer look at the second digit dialled
to see if it is 0/1 and determine long distance.  Hence, the 1+.
