TAP No. 16 - Red Box Plans

Publishes a redesigned Red Box circuit and construction notes, and appeals to readers to recruit friends to boost circulation rather than raise the subscription price. Reader letters debug regional variations of the ‘T network’ (Southern New England Bell wiring differences), discuss ground-wire tricks for pay phones, and continue the Destructory Assistance information-trading department. One letter is from a reader demanding removal from the mailing list over YIPL’s politics.

THE YOUTH INTERNATIONAL PARTY LINE
Dear YIPL,
In issue no. 15 the "T" network does not work
for the Southern New England Bell Co. system
because coin return etc. still works with only red
and green wires, even when yellow is cut. (there
is no black for S. N. E. T.)
Collect calls are accepted always at a certain pay
phone ina dorm. Could this mean that it is being
tapped? If so, how canI tell? Is there any
way that f still can work the "T" network?
-DESTROY~ CONNECTICUT.
In certain places the pay phone uses a ground
wire seperate from the phone line cable. Look
for a wire to a nearby pipe, or to an electric
fixture plate. Otherwise, try reversing the po-
larity of the red and green wires, this should
reverse ali collect and return signals.
Pay phones that don't start with 99 or 98 in
the last four digits are good targets for collect
calls. Operators usually don't accept calls to
most pay phones because they recognize the #,
Sirs,
In writing to recieve your publications my
Sole interest was in gaining knowledge about
electrical systems, Yet, upon recieving some
back issues (ordered 11/72) I have found the
political motivation of your organization totally
contrary to my own. My interests certainly do
not lie in "ripping off" the Bell system. Eventual
reform in society must come from more concrete
and benefical works (this being the primary idea
behind my involvement with UNICEF).
Because of the misunderstanding initiating our
contact, I must deziuna that all further commun-
ications cease immediately. -D, C, -N. Y.
YIPL has determined, after exhaustive testing, that the
economy has taken a turn toward heaven, thus tempting
us to raise our prices, Of course, we wouldn't think of
doing that to you, our money-drained devotees. So we
decided that the only way to keep YIPL's price down is
to increase circulation immediately. That means either
every YIPL has to sign up one friend, or a few YIPLs
have to sign up several friends. You people are taking
part in the greatest man vs. machine drama ever to
unfold in the history of civilization, and you can help
to make it a lot of fun, so help out, O.K.? Don't for-
get that the more people we have, the more we have
to intimidate Bell with, the more information we get
to use and people to use it, and the more people who
will save money on expensive calis talking to loved
ones{Aw, shucks’).

We've only gotten a few responses to our Destructory As-
sistance department that we introduced last month, which
is a shame because we've already got a wealth of great
information ready to trade for other phone info. Also we
have a special interest in city codes for foreign countries
which we're compiling into a master list, along with good
telephone numbers to call overseas, whicn we will be pub-
lishing regularly. We've got schematics for various ver-
Sions of blue and red boxes, and general info on same. So
Send us info, a stamped self-addressed envelope, and if
you want Some specific info we'll try to get it for you, as

@y THE RED BOX ao) &
ul waka AK SY
CONSTRUCTION
The largest units in the red box are the telephone earpiece and battery. Since
the unit works on 9V and has no coils, 10V parts can be used. The push buttons
are high quality units that won't bounce on you and fire the box twice. Grayhill
makes some good ones. Snap action are the best, but they make noise when you
hold the box up to the phone.
Different earpieces or speakers will produce different volumes. If a low im-
pedance (8-32ohms) speaker is used, less volume and more battery drain will
result, Increase the value of the 10 mfd. output capacitor with low impedance
speakers, and increase 22K gain resistor if necessary.
Remember, with a red box you are going to play it for an operator who will
easily recognise a faulty tone pulse. So make your solder connections tight &
use good switches. Cover the speaker holes with a small patch of thin foam
to prevent gook from flying into the magnet.
OPERATING PRINCIPLES
The red box consists of four sections, the oscillator, the flip-flop, the
timer and the amplifier. To understand how these produce the necessary tones
we'll take for example a dime sound. A dime is two pulses of 2200 cycles, each
being 60 milleseconds long, with a 60 ms. space between them. When you press
the 10¢ button, the flip-flop starts turning on and off, on for 60 ms, and off for
60 ms., continuously, This in turn shorts out the oscillator, producing on and
off pulses to be fed to the amplifier and speaker. How do we get only 2 beeps?
Well, when you press the button, the timer starts. After 180 ms. it turns off
the flip-flop, thus stopping the tones, Other sounds are produced by changing
the speed of the flip-flop and the delay of the timer. Also, the two RC pairs of
1M and .047 pulse the timer and the shorting transistor, to start the timer and
flip-flop at the same time. Current drain is approx. 7 ma, so don't worry
about the battery. You will hear some e after the tone sounds if you keep
holding the button down, but this is alright if it's faint or if you let go.
TUNING
First, adjust the 30K oscillator trimmer to produce a beep when a button
is pushed. Then, simply call a friend at a pay phone and have him deposit money.
Tune the oscillator to the same pitch as the beeps you hear. If the oscillator is
too high, raise the .0033 cap to .0047. If-the range of the trimmer is too small,
add a 30K series resistor,
Now, you should get one, two, and 5 beeps for 5,10, and 25. If not, you'll
need to adjust a bit. If you get only 4 beeps for 25, raise the 620K resistor,
This may, however, the 5 and 10 beeps. The 680K resistor is the number
of beeps for the dime, and the 120K is for the 5 button.
The 150K resistor controls the speed of the flip-flop for 25. If you get 5 beeps,
but they're too slow compared to the phone your friend is at, you can speed
them up by lowering it. This will give you more beeps, however, in the same
period of time that used to give you 5 beeps. So then you should lower the 620K
until you get 5 beeps again, and then check for proper beeps’on the other buttons.
Always adjust 25 first, then do 5 and 10.
5¢ = 600n
10¢= 60 on, 60 off, 60 on
25¢= 35 on, 35 off(5 times)
CALLING
Go to a pay phone, dial your number direct(after depositing a dime){or 20¢)
and when the operator comes on she'll ask for more money, and possibly even
return your dime. Now, very slowly and quietly put the red box up to the mouth-
Piece and press one button per coin, and be sure to pause several seconds in
between each coin, just as if you were reaching for the money in your pocket
and fumbling to put in the coins. If the operator gets suspicious it could be for
two reasons; first, you may be off tune or off speed. In that case tune it. Sec-
ond, the operator may be suspicious because in some areas a visual indicat-
ion of insertion of cains is provided for the operator.. So the eperator may say
something like "I'm sorry, sir; but that didn't register". Just mosey along to
another phone booth. You'll find the red box is the safest box to use and easy
and fun to use, too. Even the operator will thank you!

TEL-COM is a computer designed by two San Francisco
engineers. It is essentially a telephone caller with a re-
corded message. It can be programmed to call up to
50, 000 homes before being reprogrammed. Oh yes, if
your line is busy it waits and calls you back. A lot of
laughs when your taking a bath, or just sleeping around
the house. (sic!)...Then there's the "fone freak foiler foiler””
which is merely asking phone-phreaks everywhere to
spend a few minutes everyday dialing long distance info
and whistling (or blue boxing) 2600.Hz and after getting
an open line hanging up. This will activate the telephone
company's foiler with a false alarm. If enough people do
this, well you know the answer to this one...A recent
Bell Telephone campaign and PR sheet claimed that 90%
of all coin phones, in New York, were in working order at
any given time. However, a recent YIPL survey of coin
phones in the Manhattan area showed 83 out of order. ..

couldn't tell us what the hidden costs were) Since we never
got the onion rings we refused to pay. A big burly looking

that next time we came here and ordered onion rings we'd have

IMPORTANT NOTICE
..- about the enclosed 1973
telephone credit card.
To make certain no unauthorized
person is using your card, the tele-
. phone operators who handle credit
YY card calls may ask you a question or
@ Sri two whenever you place such a call.
They're the type of question that
can be answered easily and quickly
by @ person having a credit card, but
should discourage an unauthorized
user from trying to complete the call.
We hope you'll understand that our
Operators will be doing this for your
Protection and ours.
As an added precaution we urge
you to treat this card as you do your
other credit cards:
® Notify your Business Office

e Do not give the card or number
to anyone else to use.
Thank you for your cooperation.
@) New York Telephone
Since credit card owners are receiving
these notices with their new credit cards
we can expect to play some games with
the operators this year. Don't sweat, the
questions are only designed to scare you
and make you hang up, thus giving it away.
Though you might get a few questions like
the name of the company, city or area
code of the credit card number, you'll
have no problem if you keep cool. The
operator knows at most the name of the
city and area code , not the company's
name. So have your number memorized,
and if you need the code numbers for
certain cities, get YIPL #8, and be sure
to read our reprint on making credit card
calls. Also write in and tell us what kind
of questions operators are asking in your
part of the country.

Many times people ask YIPL questions that we don't have
the answer to. Questions dealing with what operators know
and don't know, how phone traces are done, and general
policies of the Bell's crack security gang led by the fear-
le®s Joe Doherty and his turtle Flash. We need people to
answer questions like whether ESS will allow Blue &
Black Boxes in the areas where they live. We need oper-
ators to tell us how they know when enough money is
put into the phone to fill it up and it has to be dumped.
Tell us anything and everything, don't sign your name,
and tell’'us if you don't want us to print the letter. And
if you have friends who work for the kompany, have them
write us.
YIPL, it is said, has its better days. And although we're
doing better in mailing now, the Post Office isn't. YIPL
is mailed third class. Now first class goes slow, and even
second class doesn't go much faster than osmosis, but we
go at the very end of everything else, when we go at all.
And there's no sense trying to make it any better because
postmen steal your mail, our mail, and everyone else for
that matter. So be patient. Allow 2 months for delivery of
a newsletter, 1 month for back issues. And do not send
cash or stamps through the mail, BECAUSE THE POST
