- When my home-town exchange went non-SXS last year, they lost the
- ability to use four-digit local dialing -- even though the switch
- could have supported the town as a Centrex group with four digits.

- Fred's comment (in a published "planning guide") was not individual
- opinion, but that of the "North American Numbering Plan
- Administration", headed up by Fred. You have to view the comment in
- context with the REASON for the comment.
-
- The guide assumes a time 20-30 years hence, when the use of overlay
- NPA's will cause a lot of "local" calls to require dialing of another
- NPA. In such cases, the callers from those numbers will have to
- (usually) dial "1+" on a majority of their calls. All callers will
- have to remember to check the NPA of any neighbor's or business phone
- they use, to determine if 1+NPA is needed. Also, in 30 years, many
- calls will be made from phones that have the intelligence to do
- dialing from other stimulus (voice, etc.). Thus, requiring ten-digit
- dialing will not be "onerous" and will permit calling any party
- without the need to first know from where one is calling. And it will
- "free up" the leading "1" for other uses, perhaps in aiding the
- conversion to 4-digit NPAs in the far-distant future -- if the first
- such NPAs are 1XXX, they could be easily differentiated from the "old"
- NXX-XXX-XXXX numbers.

-
- Al Varney - just MY opinion.
