This article will tell you how to change a normal touch tone
keypad and convert it to a portable unit. In addition, we
give the touch-tone frequencies.
 
First of all, the tones made by a touch tone telephone are not
single tones, they are a combination of two tones, making "DTMF"
(dual tone multi-frequency). The normal tone telephone dials 12
different signals, but is capable of dialing 16 different signals
(see bulletin on silver boxes).
 
The power required by a keypad is about 25 volts, but they will
work with as little as 15, thereby allowing the use of two 9-
volt radio batteries.  As you may have guessed, they are also
designed to operate with a telephone type speaker (and phone
line), and not the standard 8-ohm speaker which needs to be used
for adequate volume.  To accompolish this, we use a matching
transformer, this is one of those miniature ones available at
Radio Shack.  Enough of the theory, now for the circuit.
 
You will need:
 
A touch tone keypad
A miniature 1000 to 8 ohm transformer (Radio Shack # 273-1380)
A standard 8-ohm speaker
Two 9-volt radio batteries
Two 9-volt battery clips
A case to put it all in (optional)
 
A few construction notes, I suggest that you solder and tape all
connections.  It is also important to read this entire bulletin
before attempting to construct this.
 
First, connect the RED wire of the transformer to either
terminal on the speaker.  Now connect the WHITE wire from the
transformer to the other terminal on the speaker.  Next, connect
the RED (positive) wire of one battery clip to the black wire of
the other battery clip.  Now connect the the remaining RED wire
on the second battery clip to the GREEN wire from the touch tone
pad.  Connect the BLUE wire from the touch tone pad to the
ORANGE-and-BLACK striped wire from the touch tone pad.  To these
two wires, now connect the remaining black lead from first
battery clip.  You have now finished the power connection to the
keypad.  Connect the BLACK wire from the keypad to the BLUE wire
on the transformer.  Next connect the RED-and-GREEN striped wire
from the keypad to the GREEN wire on the transformer.  The BLACK
wire on the transformer should not be connected to anything,
along with quite a few wires from the keypad.  The connection of
the keypad is now complete.  All you have to do is connect two
nine volt batteries to the battery clips, and you'll be ready to
go. You may want to mount it in a case for easy portability.
Note that the silver box modification CAN be made to this unit,
allowing complete remote phreaking.  When none of the buttons
are pressed, this unit uses NO power, thereby eliminating the
need for a power switch, and extending the life of the
batteries.
 
The following are the frequency combinations generated by each
button on the keypad.

             3 WAY CALLING           
       Written by The Mortician      
 
 
 
     1) To do this you need two phone
lines with the jacks somewhat near each
other, or at least access to each jack
from a comman place as you will have to
run wires between the two different jacks.
 
     2) Now open up each jack and take a
look at the inside. (You can open it by
unscrewing the center screw on most modular
jacks.) You will see 4 terminals(Places where
wires meet) There should be one Red, One yellow
One Green, One black. Now what you will do
is take two extra wires(Preferably one Red
and the Other Green from your garage or where
ever you keep that shit). Now take your
red wire and attach one end to the Red
terminal. Do the Same with the green.
 
      3) Repeat step 2 with the jack for the
other line. So Now you will have a Red and
Greed Free wire for each Line.
 
      4) Now Get a Single Pole Double Throw Switch
From Radio Shack(Like $.28) Or where ever you can
find one.
      5) Now put the switch in between the
two green wires and the two red wires. Such
that when you turn the switch on the green
wires will be connected and the Red will be too.

       Use: Well Say your two lines are 6666 and 7777.
Who cares about the prefix. Any way I will call them
6 and 7. Pick up 6 and call somebody. Now call another
person on line 7. Throw the switch. The Person on 7 will
now be able to hear the person on 6 and vice versa. You
can also hang up one of the phones and talk through the
other and both will still hear you. Because of the
way this is set up the person on 6 will hear the peron
on 7 faintly but it isn't that bad. That is true for 7
hearing 6 too. Fool around with id and see what you get.
