Alas, many of the newer ones are capable of translating those "cute"
numbers like 1-800-ABCDEFG. Which means that when you dial A, B or C
you get 2. And you get 3 for D. *Older* Hayes and USR modems could
dial the ABCD tones. <sigh>

  The ABCD tones are merely the same row-tones with a different
(higher) column tone added. If you have a DTMF generator, they can be
useful: If you have a Voice Mail Box, you can often use onf of the
ABCD tones (back when I was a phreak, they were always referred to as
autovon tones) in your passcode. It will prevent access to your box by
just about anyone - the person would need to KNOW your passcode, and
he/she would ALSO need something that would generate the tones
(although, most AT-compatible modems can do them, these days).

My two cents.

Recently I had a request from a friend in Brazil to get him a
phone-radio system here in the US that he could use to connect a
remote place in a farm to his phone at home, and the rest of the
world.

I have never heard of these kind of systems before that are
essentially a phone <=> radio <=> phone kind of link, and that allows
one to install a phone on a remote place, with distances up to 60
miles, so I went on the search for some information.

Then I learned that there are some companies here that sell these
systems (mainly manufactured in Japan); that they are illegal to use
here in the US; and since them I have been in touch with a couple of
companies that sells these systems: Phone Masters and Megatronics
International; both of the LA area, but getting information on these
systems and on their reliability has been hard.

For example I have not been able to get the answer for the simple
question: What happens if there is a mountain in between? Does it
only get worse?  Does it work at all?

Where can I get some information on these radio-phones being sold in
US?

It's not an A/D chip, it's a DSP chip, which is the same thing but a
different name (I think).  A DSP is a souped-up microprocessor that is
designed to process analog data (i.e. sound).  There's a schematic for

I use this with hotel phones, but I first try to clip directly on the
pair somewhere.  This is assuming I can't use a regular modular plug.
Many hotels have standard modular jacks, but they often do various
tricks to make them unable to disconnect, apparently to avoid having
the sets ripped off.  Sometimes they cut off the plastic latch lever,
making it a bit more difficult to remove.  Other times they have these
funky screwed-on plastic blocks up tight against the lever.  I can
almost always get these off within a few seconds.  (Once I <blush>
pulled the cable out of the modular plug.  Since I carry an el-cheapo
Radio Shark modular tool in the bag of tricks, I reterminated it, sans
plastic widget.)  I've even seen the modular plugs glued in place.
This is a bit much.
 
I have thought of (and tried) using it on pay phones, but I've never
found one where I could loosen the mouthpiece cover.  I don't know if
they use some kind of a special locking screw-on cover, they just
screw them on >>VERY<< tight, or they glue them on.  In any case, I
have never found one that screws off by hand.

One place it will help is on "sequence calls" made on AT&T. For some
unknown reason, AT&T has started waiting after dialing subsequent
calls on a calling card. "You may dial another AT&T-handled call now"
is the announcement. After you dial the call, there is a long pause
and then, "Thank you."  If you press the '#' after the number, the
"Thank you" comes immediately and the call is instantly processed.

I don't know the "rules," if any, for cordless phones, but the FCC
requires radio amateurs experimenting with spread spectrum to use a
known, LINEAR, generator for the spectrum spreading code.  The code
generated by a linear shift register, pseudorandom code generator
having n stages can be "broken," by solving 2n+1 linear equations.

Also, linear codes are much easier to generate than are nonlinear
codes, suggesting that Cincinnati Microwave, in an effort to control
development costs while being able to choose codes from a very large
set, may well be using linear codes.

It sounds as if the sets described are effective only against
unsophisticated users who tune in using an older TV with a tuner that
covers through channel 84.  It wouldn't take much more than a code
demodulator and a PC with suitable interface to give a savvy
eavesdropper the ability to continue his/her hobby.

In fact, if truely secure encryption were this easy, Cincinnati Micro
would be making big bucks on the encryption technology alone and
wouldn't worry about selling phones.

There is a fairly straightforward technical problem here.  The
contents of the magnetic stripe on the back of a credit card are well
standardized (there are ANSI and ISO standards defining them) and
there is only provision for a single credit card number on the stripe.
There are three tracks on the stripe with the number recorded three
different ways for historical reasons, but they all have the same card
number.  You can't change it without changing the millions of existing
credit card readers found in businesses around the world.

If AT&T has enough muscle, they might be able to get themselves
assigned MC and Visa card prefixes that would identify the card as a
telco calling card.  It's my impression that the banks were rather
upset when AT&T got into the bank card business using a rather
peculiar little bank that does nothing but process charges for AT&T
Universal cards, so I doubt that the MC and Visa organizations would
do AT&T any favors.

A place where I am doing some contract work has an old interphone
system installed but not in use.  The sets have twelve button keypads
which do not emit tones.  The numbering scheme seems to be two digits,
though the system as installed has only six or seven sets.
 
There appears to be no central switch -- each set is wired to a common
five pair cable.  There is a central 24V power supply.  Each set has
a plug -- a clip really, that appears to set the address, though it's
not clear how the dialed digits are related to the plug setting.
 
The sets look like something from the early 1970s, but if so, I'm
surprised that enough electronics of that vintage fits in quite small
packages.

Has anyone heard of these or at least of the company ?  I would like
to get a manual.

They break the dialtone on a 1A ESS; I will have to try them on some
other types.  They does not seem to be accepted as "dialed digits".

They might be useful as some sort of special control signals for
something like 710, but the requirement of special hardware, like
ABCD, would preclude the use of the service from "normal" phones that
litter the land by the millions.

First of all a plug. As mentioned a while ago, we did start up a
mailing list for Northern Telecom switches, anybody who wants to join
should send mail to telswitch-nt-request@dg-rtp.dg.com.

I should think going off-hook every two minutes would give your PBX a
nervous breakdown. There are only so many slots configured to provide
dial-tone, and when you go off-hook you compete for one of those.
Everybody going off-hook every two minutes, I expect lots of people
would not get dial-tone at all.

Sounds like your company balked at paying $25 for replacing your
phones with new phones with message waiting lights. What you need to
do is retro-fit your phones with lights. You can do this in many ways,
places like Graybar will supply just the LED, or a new faceplate with
the LED installed, or gadgets with modular jacks that will plug into
your phone line. All these will respond to the 90 to 130VDC that the
PBX will put on your line when you have a message waiting.

Note that having a message waiting light or stutter dial-tone is an
either-or option; you can't have both. The people who administer your
PBX will have to switch each line from stutter dial-tone to message
waiting light as you equip the phones.

Hope this helps.

	If you want to do telnet over ethernet from an MS-DOG machine
into a Unix host, you have three Public Domain type choices:

	Kermit (MSKERMIT V3.11)  The best VT100 terminal emulation

	NCSA	The next best VT100 terminal emulation

	KA9Q	Terrible ansi/nansi terminal emulation

	All of the above three use the "Clarkson Packet drivers".

	Now the KA9Q stuff has other advantages besides telnet. It will
let you do ftp, ping, SLIP, amd SMTP (unix style email).

	But wait. There's more! If you load KA9Q on your MS-DROSS
machine, it can become a host and other machines can send it mail, ftp
files from it etc.

	Now for those who want Telnet with so-so VT-100 emulation and
ftp, slip ping etc, there is Sun's PC-NFS. This will cost you about
$350.00 per machine.


> Someone else is looking into the Mac version.

	There is a Mac version of KA9Q.
