Subject: April NPA Report
Date: 31 Mar 94 20:24:00 GMT
Organization: Moscom Corporation, Pittsford NY


This is my quarterly report on the number of exchanges in each NPA in
the NANP.  It is derived from information in FCC #10.  This is article
#13 in the series.

FCC #10 is a tariff issued by BellCore that contains all the area
codes, exchange combinations in the North American Numbering Plan
(NANP).  It also contains lata information and V&H coordinate
information.  There is a lot of additional information that I don't
use, so I won't add here.  It is available through a number of
sources.  The one closest to the FCC is ITS, which can be contacted at
202-857-3800.  My company compiles this information for use in its
products and does not seem to be interested in selling this
information.  Queries are still flowing through the bureaucracy.

I have used pages that are effective prior to April 21, 1994.  I am
not responsible for the information supplied in FCC #10.

I have not included the following in my counts of exchanges:

- NXX's that are not dialable by a standard user (ie nxx's that begin
with a 1 or 0).
     
- Mexican exchanges in the 52? series of area codes.  I've got them,
you can dial them with 011, but they're not really NPAs.

- Exchanges that are non-dialable in the 88? series of area codes.  I've
got those also, but you can't dial them, so I'm not including them.

Numbers that begin with 88 are nondialable stations in the US, Canada and 
Mexico.  They are ranches in the middle of the Nevada or Texas desert,
or isolated outpost of civilization (always wanted to use that phrase) in
the tundra of Canada.  I find place names like the Bar J Ranch, Double B 
Ranch, and JD Dye, Texas, Amargosa, Corncreek and Reese Valley, NV, and 
Chick Lake, Redknife and Taglu, NT.  I gather they are ringdown stations, 
or radio-telephone stations.  [It has been noted in c.d.t. that at least
two of these numbers are for a bordello on the NV-CA border.]

The fields are:
                        ------------ rank last in January, 1994
       213: 736 (1, 7)

Note: The Los Angeles Area (213/818/310) area will receive an overlay area
      code.  While none of these NPAs are in the top 20 (they are 64/47/32),
      this is an area of rapid telephone growth.

->  The NPA that is largest and is not splitting nor has plans, at this time,
    to split, is 703.

->   The 3 smallest NPA's were 302, 906, 807.  They are now:

      302: 134 - Delaware (+2 exchanges)
      906: 117 - Michigan's Upper Peninsula (no change)
      807: 107 - Western Ontario (+1 exchange)

->   The NPAs with the greatest growth rates are:

  NPA   % growth

         512     4.91
         917     4.76

         515      0
         519      0

Just for grins:

   The most used NXX (not counting 555) is 754 used in 118 npas.

   The least used are:
        211 and 311 used only in 212,
 900 used in 213,
 950 used only in 716 (my NPA), 
 and 959 used only in 808.

Telefonos de Mexico is offering an audio text product much like our
dial 900 services in the U.S. It is dialed within Mexico by dialing
91-801 xxxxx. The cost is whatever specific service cost associated
with the dialed phone number plus the cost from the caller to Mexico
City.

If your business in Mexico has not prohibited calls from your PBX, you
should consider blocking this number. As in the U.S., your
business/hotel/etc. cannot reliably determine the cost of a call
before you are billed by Telmex. As a result, you are likely to be out
some money.

We provide businesses in Mexico with call pricing data and call
rating software. Our software will rate calls from any place in 
Mexico to anyplace in the world. We cover local, national, and 
international calling using a full V&H database.

We can also provide Mexican private rating data for those who need it.

Subject: 911 Chatline


New service to pay for cost of enhanced 911
Date: Fri, 1 APR 94 8:20:19 EST

NEW YORK (AP) -- Century Communications announced today plans for an
exciting new 900 service, with profits to go to help defray the cost
of installing and maintaining enhanced 911 service across the country.
Called, 'The 911 Chatline,' it allows callers to choose an area of the
country, and to listen to 911 emergency calls from it.

When asked what prompted this unusual foray into the 900 business,
Century spokeswoman Fawn Lebowitz said, "In recent years we've seen a
dramatic increase in the popularity of reality-based television
shows. The 911 Chatline allows callers to experience real-life drama
while it is going on, all from the comfort of their own home."

While listening to the emergency calls going through, callers to the
Chatline have a number of options. They can listen to just the 911
calls for the area they select, switch their call to a different area,
or, probably the most interesting option, connect their call to the
'911 Chatline' to discuss the details of the emergencies with each
other as they happen, and before the police have even arrived!

Thanks to new voice recognition software from AT&T, callers do not
even need a touch tone telephone in order to use the service. They can
choose which 911 center to listen to simply by saying the area code
and city that they are interested in listening to calls from. Calls
are directed to the 911 center nearest this location.  

As 911 centers sign up to recieve their share of the profits, they are
connected to the Chatline network.  Century says it has already wired
up over 50 centers, and that it has coverage in most major
metropolitan areas. They plan to have the whole nation wired by April,
1995.


[TELECOM Digest Editor's Note: Probably by April 1, 1995 ... Readers,
take care and think it over before writing me in response to this one.
I guess by now everyone has heard about the infamous magazine article
this past week which talked about new FCC regulations which '...ban
speeding on on the Information Highway or driving on it while under
the influence of drugs or intoxicating liquors ... and which ban any
discussion of sexual matters using networks connected to the Information
Highway ...' A reference number was given and there have actually been
a large number of angry calls to Senators and others in Washington, DC.
April 1 always brings these things to the net.   PAT]

A twist to a recent thread on 911 over cellular phones...

I am trying to gather information on the use of so-called "extended"
911 over cellular phones (e.g., the 911 provider can automatically
zero in and locate the caller's location).  This is relatively
straightforward for fixed-address phone numbers, but with nomadic
telephony it becomes more complicated.

What is the state of the art in this area?  Can anyone point me to
resources that might discuss the technical, legal, and management
aspects of this problem?

Random thoughts and musings would also be appreciated.  Thanks.

Subject: Is 800 ReallP portablY yet?
Organization: FidoNet 


I just received a "New Releases" flyer from Bellcore, and one of the
publications listed was a "Special Access Codes 800/900 NXX
Assignments" (SR-OPT-001843) dated Dec. 1993. For USD$40, one can get
the NXX assignments for 800 and 900 special access codes in North
America. The thing is, there was supposed to be a cutover to
"portable" 800 service last year which rendered the idea of 800 NXX
assignments to carriers meaningless. Canada should also have 800
portability by now (as of January from my latest news).

Does this mean there are still some carrier NXX assignments for 800,
or at least 900 service?

Tangent: a recent ad for a company just outside Toronto listed its
regular number as (905) 819.wxyz while its toll-free number was (800)
819.wxyz, the seven digit components being identical.


[TELECOM Digest Editor's Note: After portability started, I do not think
all the numbers were just tossed in a big pot for everyone to pick from.
I think they were left with the carriers which had them all along but the
earlier prohibition against moving them was dropped. If you, for example,
want a certain 800 number and it is found to be inactive and available,
you go to your carrier of choice and ask for it. They in turn check the
database and find that the number is in the custody of carrier X, where
it always had been prior to portability. Your carrier has to then go to
carrier X and ask to have the number released to them, and carrier X cannot
frivilously refuse to comply. Now if you have existing service with 
carrier X and you want to move it to another company, then you have to
sign a standard form all the carriers seem to be using which authorizes
the change. And it must be properly filled out. AT&T for one has been very
stubborn about cooperating with portability. Whenever the form is sent to
them, they always refuse to accept it the first (and usually second or
third) time around, claiming it has been filled out incorrectly. They claim
they can only work with the signature of the president of the corporation,
for example, even if he has nothing to do with the phone service at all.
Then they challenge the signature and claim it must have been signed by
someone else fraudulently; etc. The carrier losing the account is given
72 hours after each time the form reaches them to challenge it, contact
the customer themselves and eventually give over the number or refuse to
do so (without additional 'verification'). In summary, if you try to get
a *working* 800 number away from AT&T, it is not easy. 

When it comes to 'good' numbers (i.e. they spell words or end in x000
or some other desirable combination) which are idle from AT&T, then AT&T
always claims the number is 'reserved' for a pending customer. They never
can produce the name of the so-called customer of course, and although
reservations are theoretically only good for sixty days (at which point
a carrier has to make it available without further hassles) AT&T keeps
on renewing the reservations on the numbers they want. Protest all you
like, it does not matter. The big three carriers seems to have an unwritten
rule which says you keep out of our pool of 'good' numbers, and we won't
raid your pool of 'good' numbers where idle numbers are concerned. That 
is, if you as a potential customer see that a number is idle and ask your
carrier for it, chances are likely they will try hard to avoid bucking
AT&T to get it ... of course as an existing customer you can change your
800 away to wherever you want -- they can't give you any bull about the
number 'is not available, it is reserved by another customer' -- but
AT&T will insist that the president of your company sign off on it and
even then they will stall. So although portability is the law, it will
only work as it should when the FCC orders all the carriers to start
responding promptly to customer requests for numbers which 'belong' to
other carriers and to quit reserving numbers for customers who do not
exist in order to hang on to desirable numbers.   PAT]

Subject: 900 and Other Premium Numbers (was Pager Scam)
Date: Thu, 31 Mar 1994 14:20:25 -0500
From: Atri Indiresan <atri@eecs.umich.edu>


I thought that when you called a premium number, by law, it was
required to have a recording that told you what the service cost, and
gave you thee seconds to hang up to avoid invoking any charges? I
remember reading this a long time ago, and it was the case on the one
occasion I had to call a 900 number.

Does this rule apply only to 900 numbers, and not to local premium
services? Or is it voluntary and only more "respectable" services
follow the rule?

It seems to me that if this were applied to all numbers to which
anything but the normal toll charges applied, all such scams would
collapse.

As an aside, 900 numbers get a lot of publicity, and most people know
that they are expensive to call. Until I started reading the Telecom
digest, I was not aware of the existence of 976/540 or any other kinds
of premium numbers. Offhand, I cannot recall seeing a single
advertisement for local premium services, but anyone who has ever
watched late night TV cannot help being aware that 900 calls are
rather expensive.

Is there anywhere a list of surcharged prefixes in the U.S.?  In most
places 976 is used for non-porn announcements, but the list of other
surcharged prefixes seems to be large, growing, and largely
undocumented.

Here in eastern Mass, for example, the prefixes (valid in both 617 and 508)
are:

 550 - live chat lines
 554 - live porn
 920 - business info
 940 - recorded porn
 976 - recorded general info

You have to ask in writing to get calls to 554 and 940 turned on.

I am astonished at the report that Sprint billed the surcharge for a
212-540 number.  Has anyone else ever had this happen?

Subject: AccessLine and 700 Service Information Wanted


Does anyone have any experience with AccessLine service or know how
popular this service is?  AccessLine is a personal communications
services offered via landline telephone service through local
telephone companies (US West, Ameritech, BT, etc).  It allows you to
set up one number access with a personal service profile that will
forward calls where you want, allow prioritization of forwarded calls
via voice prompts, interaction with independent fax or email systems
for paging, etc.

This seems similar to the AT&T 700 Easy Reach Service introduced a
couple of years ago, but I can't find any information about how useful
these products are and how much they're selling.


Thanks in advance,

they state very good rates with no enrollment fee, monthly charge, or
access costs. They also have a travel phone card for those on the
move. Sample rates from Europe are:

Netherlands to USA $0.40/minute
Austria to USA  $0.34/minute
UK to USA  $0.29/minute

This seems almost too good to be true. Does anyone have experience
with this company or dialback companies in general?

Their phone number is (France) +33 1 39 28 00 19 (phone/fax) US +1 305
386 5343 (6352 fax)

If anyone happens to call the Miami Better Business Bureau I would be
interested in their record :-)

Subject: Getting Wired: Leased Line vs. Dial-up For 14.4kps Data Comm


Our small non-profit organization is trying to become an Internet
service provider with a budget of ~$20,000 which demands that we do
everything that we do on the cheap.  Our plans are to connect our
Linux-based PC to our local Internet service provider, which is using
rack-mounted USR Courier v.32bis modems.  I'm trying to figure out the
best way of doing this given two options:

(1) We get a regular POTS line installed, ($40/month, $60 for the
installation), buy a relatively cheap 14.4kbps modem (~$300) and have
our service provider dedicate a dial-up line to our exclusive use.

(2) We get a leased data line (the phone company calls this an LDDS 
circuit, $32/month, $180 for the installation) installed and buy a more 
expensive but leased-line capable 14.4kbps modem (~$900) and connect 
directly.

The first option works out to a cost of $840 for the year, the second 
option $1284 for the year, a not-insignificant difference.

I do not know enough about high-speed modems and leased lines to be able 
to evaluate the two options technically, nor do I know enough about the 
telephone system to know if I'm missing a third [or fourth] option that 
would be a better route to follow.  I would very much appreciate any 
advice in this regard.

Subject: Satellite/Mobile Data Applications


I am currently investigating what companies provide applications for
mobile data/satellite networks such as remote data collection, fleet
management, stolen car tracking, etc.  Does anyone know of companies
which provide these kinds of applications or would be interested in
providing these kinds of applications?

Subject: Voice and Data Simultaneously Over Modem?

Hi,

I have read in recent articles in computer magazines about two
different schemes which allow SIMULTANEOUS duplex voice and data
transmission using high speed modems.  Voice is severely compressed
and then multiplexed with the normal modem data.  For example, a user
could be connected to an online service and type away while
simultaneously talking voice to support staff.

Does anyone have ANY info about the above?  It is a software standard
which can be used with standard modems.

Direct replies by E-mail appreciated.


Thanks,

Does anyone have any info on companies that provide a FAXMAIL service?

What I am looking for is a FAX Number I can give out that receives
faxes and then allows me to retrieve them from any fax machine by
dialing up my code.

There has been much talk as of late on the new area codes in the Los
Angeles region and elsewhere.  I haven't seen any comprehensive list
of announced area codes to be implemented in the future.

In particular, I believe that I read somewhere that there will be a
second (third if you count outlying metro) area code for the Houston
area (pagers and cellular).  However, I've not seen a posting on this
subject.

Does anyone have a comprehensive list of thus far announced codes
including Houston?
