- 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.)
