By MAY WONG AP Technology Writer

SAN MATEO, Calif. (AP) -- The promise of Internet-based video has long
been hamstrung by copyright and piracy worries, slow dial-up
connections, technical challenges and consumer disdain for watching
blotchy videos on their home computers. But a Silicon Valley startup
is tackling those obstacles, hoping to become the first major provider
of cinema straight from the Internet to the living room boob tube.

Subject: Verizon Wireless Takes a Bite Out of 'Spam'


Nation's Leading Wireless Carrier Wins Legal Injunction Against RI-Based
Wireless Spammer; Champions Customer's Right to Privacy

BEDMINSTER, N.J. and WOBURN, Mass. Aug. 30 /PRNewswire/ -- Verizon
Wireless today announced it was granted a permanent, legal injunction
against Rhode Island resident Jacob Brown, a known 'spammer' who
knowingly executed a systematic spam attack on wireless phones owned
by Verizon Wireless customers.  The Honorable Mary L. Cooper, United
States District Judge in Trenton, New Jersey, permanently enjoined
Jacob Brown from sending further spam to Verizon Wireless customers.

Brown and his cohorts distributed unsolicited short text messages
(also referred to as 'spam') offering mortgage loans and directing
individuals to adult Web sites. Additionally, these individuals
'spoofed' and disguised themselves by using IP addresses of innocent
persons to distribute messages, creating identification protection for
the guilty and an undercurrent of insecurity for innocent people. The
company, which has long championed a customer's right to privacy and
'spam-free' wireless environment, believed legal action was necessary
to deter future wireless phone 'attacks' that force customers to pay
for unsolicited commercial spam messages each time one reaches their
phone.

The action taken against Jacob Brown is the latest of many legal
filings by Verizon Wireless against wireless 'spammers.' Last year,
for example, Verizon Wireless filed two suits against wireless
spammers in federal court in Georgia -- which were disseminating
repeated, unsolicited, text messages to Verizon Wireless customers --
and succeeded in stopping those spam attacks.  These are believed to
be some of the only legal actions taken in the nation against wireless
spammers.

     Beware of Pop-Up Internet Ads and 'Modem Hijacking' Scheme
     - Aug 30, 2004 11:41 AM (PR Newswire)

Consumers Who Click 'yes' to Pop-Up Ad Questions Without Reading The
Fine Print Could Be Agreeing to Have Their Modems Programmed to
Automatically Dial

Expensive International Long-Distance Calls

NEW YORK, Aug. 30 /PRNewswire/ -- Consumers should read the fine print
before clicking "yes" or "I accept" to questions that appear on
so-called pop-up ads while browsing the Web. They could be agreeing to
install software on their computers that then dials international
locations. The result could be significant, and perhaps unexpected,
international long-distance charges for which the customer is
responsible.

This scam, known as "modem hijacking," occurs when a computer user
sees certain ads pop up on the screen while visiting a Web site. If
the user clicks on the pop-up, a series of questions appears asking
the user to choose a "yes," "I agree," or a similarly phrased button
to agree to the terms and conditions of the ad.  A positive response
to the question triggers a software download to the user's computer -
which will then automatically dial the international phone numbers at
random times without the customer knowing it.

The Federal Trade Commission, in response to increasing incidents
involving this scam, has posted a consumer alert on its website at:

Subject: Website Offers Caller I.D. Falsification Service


By Kevin Poulsen ,SecurityFocus Aug 27 2004  2:37PM

Overdue debtors beware: You may not be able to rely on Caller I.D. to
screen out those annoying bill collectors much longer. A California
entrepreneur has a plan to bring the hacker technique of Caller I.D.
spoofing to the business world, beginning with collection agencies and
private investigators.

Slated for launch next week, Star38.com would offer subscribers a
simple Web interface to a Caller I.D. spoofing system that lets them
appear to be calling from any number they choose. "It creates an extra
avenue for them to have someone pick up the phone," says founder Jason
Jepson.

Caller I.D. spoofing has for years been within the reach of businesses
with certain types of digital connections to their local phone
company, and more recently has become the plaything of hackers and
pranksters exploiting permissive voice over IP systems. But Star38.com
appears to be the first stab at turning Caller I.D.  spoofing into a
commercial venture. Jepson claims the service will charge a
twenty-five cent connection fee for each call, and seven to fourteen
cents per minute.

"A US website will offer Caller ID falsification service ... slated
for launch this week, Star38.com would offer subscribers a simple Web
interface to a Caller ID spoofing system that lets them appear to be
calling from any number they choose. [...] SecurityFocus took the site
for a test drive, and found it worked as advertised. The user fills
out a simple Web form with his phone number, the number he wants to
call, and the number he wants to appear to be calling from. Within two
seconds, the system rings back, and patches the user through to the
destination. The recipient sees only the spoofed number displayed on
Caller ID. Any number works, from nonsense phone numbers like "123
4567" to the number for the White House switchboard."

[TELECOM Digest Editor's Note: Well, you know what is good for the
goose is also good for the gander as they say. Debtors can also use
that service to spoof the skip tracers and bill collectors. For 
example, a common technique used by skip tracers who cannot find your
phone number anywhere is to send you a letter from some bogus company
telling you that you have won a prize; to claim the prize all you have
to do is call us on this (toll free) number and punch in the 'extension'
number shown. The letter is vague enough that they do not have to
award any prizes, but they do match up *your* phone number (which is
what they really wanted; you cannot hide it when you call an 800 number)
and the specifics of your alleged indebtedness (the 'extension' number
you were asked to punch in when you called), and you can be sure you
will get a callback rather soon from some no-nonsense person who would
like to speak with you about your debt. They don't all bother with the
ruse of telling you that you won a prize, some skip tracers employ
young ladies to write cozy, friendly, occassionally lurid letters
using pink felt tip markers to guys (males, it seems, make up the
majority of skip-traceable [or hard-core] debtors) claiming to be a
long-lost friend (of the opposite sex of course; what guy would not
fall for that one and eagerly return the call). "Call me on my office
line at 800-xxx-xxxx and ask for extension xxxxx so we can renew our
friendship." Men are always getting lured into that trap I am sorry
to say.

Now imagine for a minute if you *did* return those absolutely wicked,
nosy, spying phone calls to (a) claim your 'prize' or (b) meet the
person who had been 'flirting' with you but you returned the call via
this new web site phalsification service and gave your caller ID 
blast as 202-456-1414 or whatever. But this new web site costs money
for your phalse ID calls; why should you have to pay for the service
when you could use your FWD/Pulver phone (which can call USA toll 
frees and gives an NYC 212 number for the caller-ID blast.) Wheeee!
And a good time was had by all.  PAT]

Then say something that isn't a number.  Sometimes the system will pass

Funny that.  Considering the poor reliability, price gouging and
community disrepect earned by Verizon, I couldn't wait to get VoIP
over a cable broadband connection and drop Verizon for good. :)

I guess it depends on where you live.  Cable and telephone have both
been prevailing regulated monopolies for a long time, and depending on
where you live, one or the other is the lesser of two evils that you
must pick from.  If only DBS didn't have such a horrible latency
problem, we could all drop both services.

Thank you for the comments Charlie. Could you expand a little on your
comments about using your cell phone to answer calls dialed at your
Vonage number? I like the notion ... it is one of the main reasons I
tried AT&T CallVantage. With Vonage, if you are outside your cell
coverage area or the cellular network does not cause your phone to
ring but rather go straight to voicemail on the cell phone, is the
Vonage service smart enough to cause the call to keep ringing on the
other destinations or to go to the voicemail box associated with it as
opposed to dropping the caller into the voicemail box affiliated with
the cell phone?

Thanks!

Yes, you can get that (in the USofA) completely free; they finance the
operation on the penny or so a minute they get for the incoming call
from the PSTN.

One operation doing this is at http://www.ipkall.com.  They'll give you a
free number in an exchange south of Seattle.  No choice of where they
put you.  You get a web interface which allows you to forward your
number to any SIP proxy, such as Free World Dialup, or your own SIP
server, as you find most useful.

There is no outgoing at all.

A zener diode usually serves as a voltage regulator.  

Most kinds of diodes are intended to conduct in one direction only.
With enough reverse voltage, they will conduct the other way.  This
damages the diode.

Clarence Melvin Zener was an American mathematician and theoretical
physicist who figured out that it would be possible to manufacture a
diode that would break down at a desired reverse voltage and not be
damaged.  Bell Labs found that he was right.

If you manufacture a zener to break down at ten volts and feed it a
small reverse current, ten volts will appear across the doide.  If you
need a higher current capacity for that ten-volt supply, you can use
that zener as a reference for a power transistor.  Zeners are commonly
included within integrated circuits.

Some radios and TVs had an item called the Zennith.  IIRC, it was
applied after the Quality was installed.

No, the correct term is zener diode (pronounced zee-nar).  With a
zener diode (as opposed to a conventional diode) as the reverse
voltage is increased the leakage current remains essentially constant
until the breakdown voltage is reached where the current increases
dramatically.  This breakdown voltage is the zener voltage for zener
diodes.  While for the conventional rectifier or diode it is
imperative to operate below this voltage, the zener diode is intended
to operate at that voltage, and so finds its greatest application as a
voltage regulator.

They are named for Dr. Clarence Melvin Zener of Southern Illinois
University, inventor of the device.

Different guy. Clarence Zener was a physicist who conceived and
described the semiconductor property that Bell Labs exploited to come
up with the diode they named for him.

Zener diodes maintain a constant voltage drop over a range of current
when reverse-biased. That makes them good reference voltage sources
for voltage regulators and other voltage control circuits.

See http://encyclopedia.thefreedictionary.com/zener%20diode

"The effect was discovered by the American physicist Clarence Melvin
Zener (December 1, 1905 - July 15, 1993). Zener was an American
physicist who described the electrical property exploited by the Zener
diode, which Bell Labs named after him. Zener was a theoretical
physicist with a background in mathematics who also wrote on a range
of subjects including superconductivity, metallurgy, and geometric
programming. Zener was born in Indianapolis, IN. It is pronounced
"ZEN-ur". "

Zener diodes have a precisely designed "breakdown" voltage, at which
point they conduct "backwards". They are used for voltage regulators
in low voltage circuits, and require current limiting (usually a series
resistor) to prevent damage from the reverse current flow.

A Zenner diode is most commonly used as a simple voltage
regulator/stablizer.  It conducts if the applied voltage is greater
than whatever level it is built for, and doesn't conduct if the
voltage is lower than that value.

The Western Union website IIRC says Mailgrams are no longer provided.

Could it be that the Mailgram is provided by a separate company?

TELECOM Digest is an electronic journal devoted mostly but not
exclusively to telecommunications topics. It is circulated anywhere
there is email, in addition to various telecom forums on a variety of
networks such as Compuserve and America On Line, Yahoo Groups, and
other forums.  It is also gatewayed to Usenet where it appears as the
moderated newsgroup 'comp.dcom.telecom'.
