Portability still uses the original rate center as far as I know. Same
with wireless. The # assigned has a specified ratecenter which is used to
compute ld charges for wireline customers.
NPA/ratecenter:
select npa, ratecenter, count(state)
from (select distinct npa, ratecenter, state from npa_nxx_company_ocn) as s
group by npa, ratecenter
having count(state) > 1;
npa | ratecenter | count
-----+------------+-------
(0 rows)
My database shows that there are no cases of a npa/ratecenter that crosses
state lines.
NPA only:
select npa, count(state)
from (select distinct npa, state from npa_nxx_company_ocn) as s
group by npa
having count(state) > 1;
npa | count
-----+-------
(0 rows)
No NPA crosses state lines either.

Thats what a database is for. Mine is kinda small (164,900 entries) 'cause
it has only resolution to the lata at the NPA/NXX level. I suppose if I
loaded a lata->zip table it would expand out to 3.5M.
My database doesn't have county so I can't verify that though a zip->county
table (or lata->counties if it existed) could also handle that.

I'm not sure if this helps but I seem to remember that in some rural
border areas between Massachusetts and Rhode Island there were Rhode
Island houses being assigned Massachusetts area codes and numbers due to
their distance from Rhode Island phone exchanges.
You might need to contact the public service people who service those
two states and see if they still have this or no longer do it.

As a general rule, no. Rate centers (actually exchange areas, the
polygons corresponding to a rate center point) are state-regulated
constructs. There are some semi-exceptions, "localities" where a
border area is served across the state line, but most of these are
treated as two rate centers nowadays, even if they have the same
local calling area, etc.

Not state boundaries. An NPA/NXX combination is always assigned to a
single rate center. It may be shared by multiple carriers, who may
even home their switches on different tandems (ATT and Q allow that
on their tandems; VZ does not), but it's one rate center, which is one state.
Counties have no telecom-specific meaning. Rate center areas cross
them all the time.

Rate center area boundaries and ZIP code boundaries do not line up.
Also bear in mind that mobile phone rate center assignments are
sometimes rather arbitrary and do not necessarily align with where a
customer lives, let alone where they are at the time. There's all
sorts of ugly history behind that but let's not dwell on it here.

In iPhone, adult industry sees pocket porn market
By JOEL SCHECTMAN
Associated Press Writer
Jul 29, 6:43 AM EDT
NEW YORK (AP) -- It's a maxim of technology: Invent the newest gadget
and the porn industry will find a way to cash in.
So when Apple Inc. launched the iPhone 4 and its FaceTime
videoconference feature, it didn't take long for adult-entertainment
companies to develop video-sex chat services and start hiring workers
through Craigslist.
With more than 3 million of the phones already sold, the adult
industry stands to make big money on this new way to reach out and
touch someone - even if it puts Apple, which has always taken pains
to keep its iPhone apps squeaky clean, in an awkward spot.
In at least five cities, Craigslist ads seek models specifically for
video sex chat on FaceTime. Many of the ads even offer to throw in a
free iPhone 4 for the new employees.

Rate centers certainly cross county lines. My rate center Trumansburg
NY (see prefix 607-387) covers parts of three different counties.
There certainly used to be rural places where a telco in one state
picked up a few customers in another state, but I don't know if they
still do that. Just to deal with the regulators it'd be a lot easier
for the telcos to make them different rate centers, even if they're
still wired from the other state.
R's,
John

This is indeed the normal way to do things in a hotel. The Austrians
even went one step further: When the front desk's number is 05212
1234, room 123 could be 05212 1234 123.
Don't ask me how that is implemented technically.

Yes, he has a piece of paper from the government called a station license,
which is a binding contract.

The problem is that before Reagan, the rights and responsibilities were
all enumerated in part 73 and everybody knew what they were, but now most
of them seem to be gone and the notion that a station is actually supposed
to provide a public service to viewers or listeners and that they can lose
their license if they don't... that is gone.

No, LPTV has been around for many, many years. And there are still some
Class D low-power FM stations that predate the elimination of the Class D
license in 1978. Low power broadcasting is nothing new.

In the case of the antenna, reciprocity holds. In the case of the electronics,
it doesn't.

Once you have a model created in an anechoic chamber, you can derive the
response from any signal emission pattern you want mathematically.

That's why we have math.

Avoiding a Large Phone Bill When Traveling
By DAVID A. KELLY
The New York Times
July 27, 2010
UBIQUITOUS connectivity has its downside, especially when it comes to
the price of using your cellphone abroad. The proliferation of
smartphones and the increased use of data have made it easier than
ever to rack up huge communications bills while traveling overseas,
even on a short trip.
"Many leisure travelers with iPhones are going to Europe, not turning
off their data and allowing their apps to continue downloading data,"
said Ken Grunski, chief executive of Telestial, a company that
provides wireless services for travelers. "U.S. travelers were
already getting hammered with expensive voice calls that start at $1
per minute. I know of people that have returned home to $1,000 or
more roaming bills."
Luckily for tech-savvy travelers who want to stay in touch, there are
ways to avoid spending a small fortune. Here are some options.

In the Omaha area, the rate center spans two counties, Douglas
and Sarpy, and if you count one little burg on the very edge,
yes, part of Washington County as well.
Two of the major COs here are on Harrison Street, the county
line, and are only a few feet into Sarpy County. The NPA/NXX
boundaries extend well into both counties.
The rate centers around here do not, however, straddle state
lines. One geographic oddity which is discussed occasionally
here is that of Carter Lake, Iowa. This is politically in
Iowa, but geographically on the Iowa side of the river. Carter
Lake is served primarily by a downtown Omaha CO, but in the
712 area code and a different rate center.
A good write-up of this situation is here:
http://omahatelephonehistory.blogspot.com/2010/01/carter-lake.html
Some of the CLECs which serve Council Bluffs, Iowa, host
their services out of switches on the Nebraska side of the
river as well, but the NPA-NXXs are indeed in the Council
Bluffs rate center.
