Patrick,

  Several folks have asked for information available in some form from
Bellcore -- and my e-mail to them failed.  Perhaps you could post this
AND include it in FAQ or archive.  Thanks.

To Bob Larribeau at <p00136@psilink.com>, asking for NPA/NXX information:
    
   Information about which LEC "owns" an NPA/NXX, and lots of other
   data you might want, is in several Bellcore "products".  For example,
   the NPA-NXX V&H Coordinates Tape (primarily for billing) contains the
   OCN (Operating Company Number) for each NXX -- you can translate that
   to an LEC (or equivalent in Canada/Caribbean).

To Richard Cox, who asked for information on the NPA/NXX activity guide:

   I tried to reply, but both <cix.comp@compulink.co.uk> and
<att!compulink.co.uk!cix.comp> didn't work; SMTP says 'compulink.co.uk'
is unknown.

      -----

   So, I've attached a canned response I use for questions about
Bellcore, but the telephone numbers correspond to the normal TR/TA
document center.  The NPA/NXX information is maintained by the
(somewhat) separate Traffic Routing Administration (TRA) group, at +1
201 829 3071.

   To complicate matters, there are three PUBLIC documents published
by Bellcore's document center, but maintained by the TRA.  These are
available by contacting the document center as described in the
attachment.

 - FA20: "Telephone Area Code Directory (TACD) Microfiche"
   Contains all customer-dialable points in the North American Numbering
   Plan with the corresponding NPA.  Issued monthly.   $50

 - TR-EOP-000093: "TACD Paper Report"  As above, issued annually around
   September.  Ordered by State and Locality.  Carrier Identification
   Codes are included.

 - TR-OPT-001843: 800/900 List on Paper, giving company name and telephone
   contact for each NXX assigned with the 800 and 900 codes.  Issued
   quarterly.

  [Call the document HOTLINE in the attachment for prices of paper
  documents.]

   For all other TRA "products", or information about on-line access
to a database of routing data, contact the TRA Hotline at +1 201 829
3071, or write to:

   Traffic Routing Administration
   Bell Communications Research, Inc.
   435 South Street, Room 1J321
   Morristown, NJ  07962-1961

  These non-public documents and on-line access require signing a
"Terms and Conditions Agreement" before purchase.  You should ask for
a complete list of products and prices.  Some of the documents do not
include Canada.

   Some of the more "common-use" TRA documents are:

 - NPA-NXX Vertical and Horizontal Coordinates Tape (the "V&H Tape")
   is primarily for billing purposes, and lists (for each NXX) the type
   of NXX, major/minor V&H coordinates, LATA Code, the ROA, Time Zone,
   Place Name, OCN (TELCO) and indicators for IDDD and "Non-Dialable".

 - NPA/NXX Activity Guide lists all NPA/NXX codes schedules to be added,
   removed or "modified" (monthly).  There's also an Active Code List
   that lists all NPA/NXX codes that aren't planned to be removed or
   "modified" for the next 6 months.

 - Local Exchange Routing Guide (LERG)
   contains information on all USA/Caribbean destinations, switching
   entities, Rate Centers and Localities, Tandem Homing information,
   operator service codes, 800/900 NXX assignments, etc.
   (3 1600 BPI tapes!!!)  Mostly useful to IXCs and other TELCos.
   

  Good Luck,
  Al Varney     varney@ihlpl.ih.att.com

Al Varney - the above represents my opinion, and not AT&T's....
  (And I do wish Bellcore paid commissions for these referrals!)
