From Mod.telecom on the USENET
|
|||
|
|
|
|||
|
|
|
|||
|
|
New England Telephone has announced that NPA617 (Eastern Mass.) is
|
|||
|
|
being split, with the area outside (inner) Metro Boston and some of
|
|||
|
|
the South Shore being moved into the new NPA508. Joy of joys for
|
|||
|
|
the affected! Worcester, Lowell, Maynard and New Bedford all get
|
|||
|
|
a new area code, along with suburbs like Framingham and Concord.
|
|||
|
|
Yet the Western Mass. NPA413 is practically empty. (Who drew the
|
|||
|
|
original lines?!?)
|
|||
|
|
|
|||
|
|
In the meantime, the ISDN Standards Committee T1D1 (which I'm on)
|
|||
|
|
has faced the question of how to set up a numbering plan for North
|
|||
|
|
America, based on extending the present plan to include non-local
|
|||
|
|
exchange ISDNs? For example, Telenet wants their own NXX codes.
|
|||
|
|
Bellcore has offered them an area code, but from the "interchangeable"
|
|||
|
|
range (like "552"), so it won't be dialable from telephones until
|
|||
|
|
we prepare to run out of current-style area codes.
|
|||
|
|
|
|||
|
|
If we give the other carriers NXX codes, some area codes may exhaust
|
|||
|
|
earlier. That will, of course, force the rest of the network to
|
|||
|
|
catch up and go to universal 1+ dialing before the presently-estimated
|
|||
|
|
1995 date.
|
|||
|
|
|
|||
|
|
This got me thinking: How close to full up are the NPAs? So I hacked
|
|||
|
|
the following together based upon the V&H tape used for billing.
|
|||
|
|
Sorry I couldn't make it multi-column or get states listed. This
|
|||
|
|
may be a clue as to which codes split next. (I've added my own comments.)
