Caller ID would be great at a la carte pricing if it were priced at cost
plus a reasonable rate of return; perhaps $1.50 per month instead of the
predatory pricing by most wireline carriers. If they included universal
name delivery I could then see the price being higher; but they don't.

As late as 2001, long after divestiture, in Massachusetts there was a
separate charge of 47 cents/month to equip a residential telephone
line for touch-tone dialing as well as pulse dialing. In
http://newscenter.verizon.com/press-releases/verizon/2001/page.jsp?itemID=29740684
Verizon asked the Public Utilities Commision to eliminate the separate
touch-tone charge and roll it into the basic rate.
I don't know whether this request was granted.

As our moderator pointed out downthread, any technical fix is going to
have to be installed and used on a switch-by-switch basis, since some
people who control switches won't cooperate or can't understand how.
So even if there is a law requiring all IDs sent to the network to be
adequately validated at the injection point, it simply won't happen.
But although a "good-guy" telco apparently cannot refuse any traffic
from other telcos (at least under the law as it is), I see no reason
why that telco can't have its own list that names some of its own
neighbors (defined by network connectivity) as trustworthy and others
not. Then the good-guy telco could use one bit in the CLID strings it
sends its own customers to tell them whether it regards the string as
trustworthy. And if it doesn't, individual customers might choose to
block the call at their equipment.
This is the model I'm trying to achieve. The similar (analogous)
technique applied to TCP/IP works quite well against spam, and it's
only a matter of time before the volume of junk/spoofed phone calls
as a fraction of all traffic approaches that of spam.

Would it really?
The Internet has anybody (and everybody) able to connect and basically do
what they like with the packets they transmit, but telephony is still
essentially a controlled access network and those that provide the
connections can still enforce - by disconnection if necessary - any sort
of technical rule they like.
There are already all sorts of technical standards for connecting to the
voice infrastructure, if accurate Caller ID was another then it shouldn't
be that big a deal (for legitimate users, at least).

Knowledge is a measure of how many answers you have, intelligence is a
measure of how many questions you have.
***** Moderator's Note *****
A government could "require" that caller-id be accurate, but that
won't stop telemarketeers and/or dunning agencies from spoofing it:
there's money at stake, and the fines that _might_ be imposed are
likely to be less than the profit to be had.
I doubt that any LEC would disconnect a paying customer for spoofing
caller-id: they have stockholders to please, and acting as a rule
enforcer for a government edict might expose a LEC to tort claims,
which would raise the stockholders' ire, and isn't a paying
proposition anyway.

No, there is not. There are two _very_ different (from each other,
and from what you claim) concepts, lumped under the general name of
the "reasonable man hypothesis". One is what a hypothetical
"reasonable man" _would_ believe (i.e. the 'most likely thing') in a
given set of circumstances, the other is what said "reasonable man"
_could_ believe (i.e. anything _not_ totally 'unbelieveable') in a
given set of circumstances.

What the 'average' person does, or does *not* know about _anything_
is, legally, *irrelevant* to the 'reasonable man' hypotheses.
As for expectations, "Everyone has the inalienable right to be wrong."
Sometimes you have to let them exercise their rights.
It is not the buisness of the law to protect [a] man from his _own_
stupidities.

Whatever you think it "better be", the reality is that it IS NOT. And
_cannot_ be.

And with telemarketers who call numbers *without* verifying that they
are not cell phones. Even using recorded announcements to make the

There is no such single, monolithic, thing as "the law", to change.
There are, at a minimum_ some 246 *DIFFERENT* sets of laws that would
have to _all_ be changed in exactly the same manner, and *then* the
telcos would have to implement it. Ten years of design and testing
later, it gets implemented. And *THEN* "somebody" has to enforce 'the
law' -- correction, *ALL* 246 governments have to enforce it -- the
changes/improvement you will see will be only as good as the _worst_
of those 246 governments do at enforcement. And, I guarantee you that
there are at least 10-20 of them that, even if "the law" you demand
were passed, [would be] venial enough and corrupt enough that [they]
would take bribes from the low-lifes who wanted to continue the
scamming.

The service in question _cannot_ do what "everybody thinks" it can do,
under all circumstances. And there is *NO*POSSIBLE*WAY*, not even any
'theoretical' solution -- It can be mathematically _proven_ that it is
impossible to accomplish -- for any legislation in this country to change
that.
The -only- thing such legislation as you think 'must' be implemented will
accomplish is to give people 'warm fuzzies' and even *more* 'misplaced
trust' in a system that is not and -- without a *complete* redesign and
re-implmentation of the *entire* network (worldwide!!) -- *CANNOT* be
trustworthy to that degree.

Another reason to keep POTS: in an disaster (earthquake, widespread
power failure, etc.), VOIP or cellular systems may stop working, but a
wired POTS line almost always will work. You may not be able to call
out of town, but at least you can call the local police or fire
departments.

In _all_ U.S. jurisdictions, as far as I know, for multi-tenant *commercial*
properties, the telco demarc is where their cable enters the building, and
the building is responsible for wiring to the tenant spaces. Only for
"residential" service, and only in *some* states, is the matter handled
'differently'.

Just saw a letter to MCI customers in New York City that they are no
longer going to be providing local, local toll and/or long distance.
If the customer does nothing they are put on a Verizon plan --- (of
course the money stated for the costs is missing about 35% of the
total bill -- such as the FCC Line Charge, USF, taxes and surcharges,
or inside wiring or ....)
What is Verizon doing about the other MCI customers outside their
territory (besides continually raising they rates so that they leave)?
In CA, when AT&T's name change occurred, [they] kept the old AT&T
customers on the old plans, using "AT&T Corp." and moved the SBC
customers to AT&T Long Distance -- What happened to the AT&T customers
in the Verizon states -- AT&T has been simply increasing their rates
until they leave.

VERIZON WELCOMES MCI CUSTOMERS AND LOOKS FORWARD TO BEING YOUR TELEPHONE
PROVIDER
According to our records, your local, local toll, and/or long distance
service is provided by MCI*. MCI will no longer provide residential or
small business local, and bundled local, local toll and long distance
telephone service in your area after JULY 6, 2009, subject to state
and federal approvals. Verizon and MCI are pleased to offer you the
opportunity to receive ongoing value by transitioning your telephone
service from MCI to Verizon. While you will experience a change in
providers, you will enjoy exceptional telecommunications service if
you switch to Verizon. Please review this letter and consider your
options to replace your MCI service.
You have three options to choose from:
1. CHOOSE NOT TO TAKE ANY ACTION. If you do not select a new telephone
service provider on or before JULY 6, 2009, Verizon will automatically
become your local telephone service provider at no cost to you. Your
telephone number will remain the same.
Your new calling plan with Verizon will be Freedom Essentials. It
includes unlimited calling within the United States and Canada. Also
included are Call Waiting, Caller ID and Home Voice Mail (where
available) for one low rate of $44.99 - *49.99 per month. Certain
calling features you may have used will not be included in your new
calling plan.
2. SELECT ANOTHER TELEPHONE PROVIDER. You have the right to select any
company that is offering telephone service in your area. You must
select a new telephone provider on or before JULY 6, 2009. To make
this change, you will need to call that provider directly and you will
be responsible for any charges imposed by the new provider for making
this change. A list of most local telephone service providers is in
your local telephone directory.
3. CONTACT VERIZON directly on or before JULY 6, 2009, at
1-877-953-5552 to select the calling plan that best suits your calling
needs and to learn about current promotions for voice, video and
Internet product and bundled options.
If you transfer your local telephone service to another carrier or
your service is migrated to Verizon, you will need to re-establish any
blocking options you currently have, including 900 number blocking and
collect call blocking. If you have a long distance preferred carrier
freeze, MCI will remove it in order to transition your service to
Verizon. If you change to another carrier, you must first contact MCI
to remove the preferred carrier freeze. Once you have transferred your
service, you will need to contact your new carrier to re-establish the
freeze.
If your telephone service will be provided by Verizon, you will
receive a welcome letter from Verizon. A final bill will come from
MCI, and your new monthly bill will come from Verizon. You will be
notified in your Verizon monthly bill if there are any changes to your
rates, terms or conditions based on the services you have
selected. You will not incur any charges for the automatic transfer to
Verizon. You may change your calling plan at no cost by calling
Verizon after the transfer.
If you have any questions regarding this notice, your MCI account,
billing issues, complaints, or the discontinuation of service, please
call MCI at 1-800-444-0003. For questions regarding Verizon service,
please call Verizon at 1-877-953-5552 or visit www.verizon.com.
Sincerely,
Verizon and MCI

Putting coax in front of a jet blast deflector on an aircraft carrier
WILL produce this effect. The dialectric melts and the center
conductor shorts to the shield.

Mark,
I'm sure the putting coax cable in the exhaust path of _any_ jet
engine would produce that effect, but I was seeking information about
damage caused by the sun's rays, not General Electric's.

Actually, it's the other way around. Infrared light has a _shorter_
wavelength (750 nanometers to 100 micrometers) than satellite
television signals (1 centimeter or longer). The longer wavelength TV
signal is oblivious to the matte pattern.

This Digest is the oldest continuing e-journal about telecomm-
unications on the Internet, having been founded in August, 1981 and
published continuously since then. Our archives are available for
your review/research. We believe we are the oldest e-zine/mailing list
on the internet in any category!
