SCREAM.

Some of us would *love* to be able to call US 800 numbers and pay for
the calls. Or have a way to find out the POTS number. Even in UK-only
publications, I *still* see US companies only quoting their 800
numbers.

So what if a given state orders telcos to allow per-call blocking on
800 calls using the same code (*67 or whatever) as is used for Caller
ID?

[TELECOM Digest Editor's Note: This is a moot point simply because the
state cannot issue such a directive. They lack the jurisdiction to do

Actually this has already come up in the context of international
callers who cannot use the 800 service.  Some companies would publish
_only_ their 800 numbers, and thus reduce the value of your
suggestion.  I suppose that most folk have wised up to the fact that
some customers cannot or will not use the 800 service, and provide
both 800 and regular numbers in their ads.

You are correct. Shannon's Law is defined as C=W * LOG [1 + (P/N)]
                                                      2

Where P is the power in watts of the signal through the channel, N is
the power in watts of the noise out of the channel, and W is the
bandwidth of the channel in hertz.

One typical values for a voice-grade analog circuit are: W=3000hz,
P=.0001 watts (-10dBm), N=.0000004 watts (-34dBm). This would yield:

 C = 3000 * Log2(1+250) = ~24,000 bits per second.

Due to the nature of the Log function, its easier to increase the
value of C more easily by increasing the value of W , rather than P or
N.

The cell site can send a mobile audit request -- basically a 'ping'
of a mobile unit which does not result in a ring.

The cell site typically sends an autonomous registration request
message from time to time, causing all mobile units which receive it
to respond.  Roamers and home-system mobiles are addressed separately
for this one.

This is one of the ways in which the system attempts to keep track
of which mobiles are turned on, and where they are ... so it knows
where to page them in case it has in incoming call.

Whooh! This has some scary implications of the Big Brother variety!
If Cellular One keeps this info, it could be a real invasion of

[TELECOM Digest Editor's Note: Now come on and try to be for real!
What do you expect the rest of us to do who roam, manage somehow

at some later point trying to exchange information?  If you think
this is such a darned invasion of your privacy then either quit
roaming, don't turn on your phone (when roaming) until you get ready
to originate a call, or get out of cellular altogether. Exactly what

As has often been pointed out, this is only half an answer.  The caller
might be willing to pay for an overseas call, after all.  And the other
half of the answer is that even in if you're willing to pay, you *still*
can't do it.  As was noted,

But as I understand it, this requires you to have a USA phone number
yourself, so that it can be billed to.  Is that still true?

Actually, in all of the foregoing, "USA" should read "USA and/or
Canada, as appropriate for the particular number".  Some 800-numbers
in each country can be called from the other in the usual way.  In
fact, some can *only* be called from the other country.

1) There is no way that a customer in a foreign country can find out
   which carrier services a particular (800) number.

2) Only the "big three" carriers have "home direct" services.

3) All of the people asking this question are quire willing to pay
   USD 5.00 + USD 1.50/minute (or whatever the operator-assisted rate is)
   to talk to these companies (who then will often gladly leave the call
   on hold for 5 to 15 minutes before answering it.

About ten years ago, AMerican industry started telling people, that
for our own good, they were moving manufacturing to South East Asia.
The American workforce would henceforth be retrained for jobs in:

(a) Service
(b) Development and Engineering
(c) Sales and Marketing

In the meantime, the marketing departments of America's "Fortune 500"
companies are now staffed with people who have difficulty thinking
straight (to put it VERY politely). How else can I describe my
experience last October, when I was attending a large international
trade show in Paris with 400 American companies displaying their
products to 23,000 visitors, and many of them were handing out product
data sheets with only an 800-number for contact information?  A dozen
(American) trade magazines had printed special editions for the show,
filled with glossy color ads and press releases, which generally had
only the company name (no mailing address, no city name) and an 800
number?

Given that the IXCs fall down on their face and refuse to route calls
to these numbers, I have only two pieces of advice:

I.   To the customers: Don't buy anything from a company that has
     an "International Marketing Manager" who orders up such ads.
     If they treat customers this way in the "buttering-up" phase, how
     will they treat you after the sale ?

II.  To the telecom gang: There should be a business opportunity in
     setting up a (toll restricted) call diverter line to route calls
     to 800-numbers. Maybe make the caller listen to a 30 second blurb
     for TelePassport before giving them a dial tone good only for 800
     numbers, or for long distance calls paid for with Orance cards.
     (Which "home direct" service will accept calls from Europe for
     800-numbers served by Orange ?)

In light of the inflammatory content above, I should explicitly say
that my employer, Rockwell International is very unlikely to agree
with these opinions!

With portable 800 numbers, that strikes me as being nearly
impossible, short of calling the company on its regular business line,
and asking what their long distance carrier is.  And while you're on
the line, you might as well ask them whatever you wanted in the first
place ;-)

Thats probably why the NSFNet's Acceptable Use Policy is widely held
to be unconstitutional. The part which says that "no commercial use
allowed" restricts speech based on content. Last I heard, the
attorneys general from nine states (MI included) have given opinions
that the policy is unenforcible. Its really a moot point since the
policy is going away in the spring anyhow, last I heard.

We got it last year when they upgraded our crossbar to some sort of
1ESS system.  I figure we should have ISDN here some time around 2030,
if the installation of other features is any example.  This is in
southern VA.

Unlikely.  An 800 number costs at rock bottom ten cents a minute,
while message rates are usually more like two cents.  Even with
metered local service, calling direct is considerably cheaper.

Note that in New York City, the calls are metered, but local calls are
charged one unit (about a dime) per call, no matter how long the call
is.  If ever there were a rate plan that favors modem users, that's
it.

Flat Rate is available to all residence customers and maybe some small

There has never been a choice of pulse, rotary and tone; just the
latter two.  According to NYTel, the standard offering is rotary only
with a surcharge for tone even though most, if not all, lines can
handle tone quite nicely.

I intend to call the business office next week and make an attempt to
find out if 516-333 is tone enabled which I think it is.  I seem to
remember that 516-333 was mentioned in the first deployment of SS7
which, at least to me, means that it has either a DMS-100 or a 5ESS
switch and is able to handle either touch tone or rotary dialing.

I also find it hard to believe that tone isn't deployed in that
exchange since tone has been around on Long Island since 1965 or
before.

Here are the exchanges in the 33X series for Area Code 516:

             0     1     2     3    4     5     6     7      8    9
          -------------------------------------------------------------
      33X |     |PtJef|GdnCy|<----Westbury--->|Hksvl|GdnCy|Wstby|     |

Code: PtJef - Port Jefferson; Hksvl - Hicksville (a small tale here);
GdnCy - Garden City.

Note that all except 331 are in Nassau County and all are next door so
to speak from each other and there are a plethora of businesses and
government offices is that area.  I don't think that they'd put up
with rotary only dialing.
