Caller-id is sent as as 1200 baud signal (I think it's Bell 202 which is
pure FM, not bell 212 as usual 1200 baud).  And it's done while
ON hook (regular modems are ment to operate only off-hook).
The data is tramsmitted between the first and second rings.
If you pick up ANY phone too early, the data transmission is
aborted and there's no way for you to re-request it.

With caller-id chips such as the Motorola or Sierra being free of under
US$3, why bother modifying a modem when a module from scratch is cheaper?
There are too many modifications needed to shoehorn an old modem to
caller-id (different modulation, and the different voltages of
being ON hook / still hung up).

True enough, the caller id is NOT transmitted to you, the subscriber,
unless you pay for it.  You've got to subscribe to the service
to get it (just as with call waiting, etc).

If you are going to worry about (a), realize that those who listen
in will be doing so on equipment other than cordless phones.  Equipment
of choice includes baby monitors and scanners.

I would not worry so much about (b).  Most phones (see the recent
Consumer Reports article) use codes so that it would not be 
easy for someone else to use your base to dial calls.

It is covered in my book about phone service -- "The Phone Book",

I need a source for 8 bit linear CODECs and LPC chips (linear predictive
compression) I'm prototyping my own secure voice telephony.

Apparently the bandwidth with an 8 bit ADC sampling narrowband audio at 7khz is
too fast for todays technology. With LPC you can compress it down to 9600 baud.

If I had an ISDN phone system, then I wouldn't have these constraints.

Anyway, I'd appreciate any sources or manufacturers of telcom codecs or
scrambling chips.

Right, but not the "older" 212a modem, the really older 1200 half duplex
ones...
As caller id boxes become more and more consumer items, it won't be worth
your trouble, they'll be low cost or built into some of the better phones
that already have a display.

they all have -some- sort of regulatory oversight, but the level of this
(at least on teh interstate/federal basis) is strongly dependant on their
size.  to oversimplify, the larger the company, the more regulation.

AT&T is constantly bitching about the governmental interferecne in their
activities, as opposed to the level required over at the others.  they, in
turn, keep saying that AT&T's market share is so great that the regulation
is warranted.

 US military are developing some really cool VR machines for fighter pilots to
use.  Does anyone know anything more about this?  I'd also be interested on hea
ring perhaps some medical/electronics ideas about neural jacks.  Are they a pos

These are just my ideas, but I think that this group has a lot of potentially w

        A friend and I developed a system last semester through which
a fractally-generated, lighted, gouraud shaded (easily texture mapped
or volumetrically textured) planet (hooks are in for eventual
expansion to planetary systems) could be flown through interactively
in real-time, with the landscape being generated on-the-fly, based on
field-of-view clipping and projected viewing area, to try for maximum
performance.  (i.e. minimal wasted drawing effort).  We hope to have
a paper on it published in SIGGRAPH '94 Proceedings.
	It has full flight controls (no physics for flight, though,
which leads to some interesting maneuvers!) and can adapt itself to
run realtime on most 4D series IRISes, or run slower with a higher
level of detail (you can change the frame rate while flying) and is
currently being modified to take full advantage of multi-processor
machines.  It would not be too hard to port this system to another
graphics platform, as it is mostly (C++) processor-intensive code.
        We hope to eventually (when he gets out of his ROTC
commitment, and after I get a job [and hence a real computer, or
continue to have access to such]) further develop this system to read 
values from a database and display them realtime, using our clipping
and level-of-detail determination algortihms.

It isn't clear what you mean by this - these fractal datasets are 3D, and
any exploration of them (do you mean viewing of them) would be no different
than any other dataset you could look at in a HMD.  The basic problem would 
be that since fractals depend on a lot of detail for their beauty, you might

If by explore you mean the creation and use of 3D fractal datasets, like
I said, they are already 3D.  Although, some would be easier to use in
today's VR equipment then others.  For example, clouds tend to be a "slice"
of a 4D fractal, and are volumetric data whereas the mountains are surface
representations and thus more amenable to display on a polygon-based
graphics engine.

Sorry, I didn't make myself crystal clear...

I'm aware that fractals are three dimensional, but interacting them
with current programs (like Fractint) shows you one 2 dimensional image
at a time (for obvious reasons)...  

What I meant to say is that it would be nice to have a interface so
one can view fractals in three dimensions via a HMD.  I know how long
it can take to render even simplistic fractals (more than a second
on a Sparc 2)... So besides increasing CPU power, I'd guess that you
can decrease the amount of computation required by decreasing the
image quality (ie: resolution).  But then this is already done since 
HMD's don't have as high a resolution as most computer monitors...

I realize the image would have to be generated twice ... What I'm
wondering though is: would it be possible to get decent effects
by using a very low resolution and a simplistic fractal...

Also, since it takes quite a bit of development to create Virtual
Worlds ... this would seem to be a cheap and easy way to create
a three dimensional world...

Hope that was a bit clearer... As mentioned before I don't have a 
great deal of knowledge about fractals or HMDs...  Just thought
I'd spew this out and see what the net drags in and see if
it gets saluted, etc..

My mind swims with the possibilities...  As for the pure-entertainment

I'd imagine (*hope*) given a small enough display, a powerful processor

One in ten (technical) papers that I read on my walks through the
archives includes a call for standards. The problem is that every
group develops their own (admirable) architecture for a VR system,
usually using the client-server paradigm like X. All of these would
work, eventually, but almost none with each other.

More to the point is that the commercial concerns have their own
agenda, primarily of making a product which can sell, which means they
have to cut all sorts of corners to get it useful - none of which
involves generalising the architecture. Why do you think X runs like a
pig - because it is general. It won out because it worked just well
enough, was built for the future, and primarily was cheap, and you
could get the sources.

Frankly, I see the v-w approach going the same way. Lots of the little
companies which now have, and will continue to have niche markets
which will gradually expand, but when there is enough interest, one of
the institution developed general systems will probably take pride of
place.  (I only know of 5D, VEOS, and aviary at the moment. You can
get VEOS from the sci.v-w archives. Alternatively, a few people have
thought about starting from a MUD base - see the mud faqs for where
you can pick up their sources - but all seem to have come to the
conclusion that they are all but useless for the real-time graphically
based environment that most people mean by v-w).

	Actually the statement "Ja ne znaju etogo goroda/slova" is
	correct. This is based on "Roditelnii Padezh" of russian grammer.
	The statement ""Ja ne znaju etot gorod/eto slovo" SOUNDS OK as
