Green Box Plans

Green Box Plans                              
Paying the initial rate in order to use a red box (on certain
fortresses) left a sour taste in many red boxers mouths, thus the
green box was invented. The green box generates useful tones such as
COIN COLLECT, COIN RETURN, AND RINGBACK. These are the tones that
ACTS or the TSPS operator would send to the CO when appropriate.
Unfortunately, the green box cannot be used at the fortress station but
must be used by the CALLED party.

Here are the tones:
COIN COLLECT     700+1100hz
COIN RETURN      1100+1700hz
RINGBACK         700+1700hz

Before the called party sends any of these tones, an operator realease
signal should be sent to alert the MF detectors at the CO.
This can be done by sending 900hz + 1500hz or a single 2600 wink (90 ms.)
Also do not forget that the initial rate is collected shortly before the
3 minute period is up. Incidentally, once the above MF
tones for collecting and returning coins reach the CO, they are
converted into an appropriate DC pulse (-130 volts for return and
+130 for collect). This pulse is then sent down the tip to the
fortress. This causes the coin relay to either return or collect the coins.
The alledged "T-network" takes advantage of this information.
When a pulse for coin collect (+130 VDC) is sent down the line,
it must be grounded somewhere. This is usually the yellow or black wire.
Thus, if the wires are exposed, these wires can be cut to prevent
the pulse from being grounded. When the three minute initial
period is almost up, make sure that the black and yellow wires are
severed, then hang up, wait about 15 seconds in case of a second
pulse, reconnect the wires, pick up the phone, and if all goes well,
it should be "JACKPOT" time.
                             

Brown Box Plans

Brown Box Plans                          

This is a fairly simple mod that can be made to any phone. All it does
is allow you to take any two lines in your house and create a party
line. So far I have not heard of anyone who has any problems
with it. There is one thing that you will notice when you are
one of the two people who is called by a person with a brown box. The other
person will sound a little bit faint. I could overcome this with some
amplifiers but then there wouldn't be very many of these made [Why not?].
I think the convenience of having two people on the line at once will
make up for any minor volume loss.

Here is the diagram:

Black Box Plans

Black Box Plans                              

Introduction:
------------
At any given time, the voltage running through your phone is about 20
Volts. When someone calls you, this voltage goes up to 48 Volts and rings
the bell. When you answer, the voltage goes down to about 10 Volts.
The phone company pays attention to this. When the voltage drops to 10,
they start billing the person who called you.

Function:
--------
The Black Box keeps the voltage going through your phone at 36 Volts,
so that it never reaches 10 Volts. The phone company is thus fooled
into thinking you never answered the phone and does not bill the caller.
However, after about a half hour the phone company will get suspicious
and disconnect your line for about 10 seconds.

Materials:
---------
1 1.8K 1/2 Watt Resistor
1 1.5V LED
1 SPST Switch

Procedure:
---------
(1) Open your phone by loosening the two screws on the bottom and
lifting the case off.
(2) There should be three wires: Red, Green, and Yellow. We'll be working
with the Red Wire.
(3) Connect the following in parallel:
     A. The Resistor and LED.
     B. The SPST Switch.
In other words, you should end up with this:
              (Red Wire)
           !---/\/\/\--O--!
(Line)-----!              !-----(Phone)
           !-----_/_------!
          /\/\/\ = Resistor
          O      = LED
          _/_    = SPST

Use:
---
The SPST Switch is the On/Off Switch of the Black Box. When the box is off,
your phone behaves normally. When the box is on and your phone rings,
the LED flashes. When you answer, the LED stays on and the voltage
is kept at 36V, so the calling party doesn't get charged. When the box
is on, you will not get a dial tone and thus cannot make calls.
Also remember that calls are limited to half an hour.

p.s. Due to new Fone Company switching systems & the like, this
may or may not work in your area. If you live in bumfuck Kentucky,
then try this out. I make no guarantees! (I never do...) --
