                               Introduction
        Since the beginning of the telephone revolution, there have been ways to
trace a line. When there used to be operators with plugs and huge switchboards,
they could manually trace the line. Then came the crossbar switching, in which
they could trace the line three ways: Lock-In tracing, manual tracing (Never
done, anymore), or time syncronization. The ESS (Electronic Switching System)
brought an "Impossible" to beat tracing mechanism, ANI.

                      Chapter One : Lock-In tracing
        Lock-In tracing is exactly what the name says. It is a type of tracing
most often used by the FBI. The method of which Lock-In works is quite simple.
When a conversation is going on, there is voltage going through the line to keep
it open for those people talking. When lock-in is used, after the caller-to-be-
traced hangs up, a special FBI machine sends voltage down the line to make the
Phone Co's machines think that the line is still being used. Then that gives the
FBI time to trace manually.

                               The DIFT Box
        There is only one way that I have heard of beating Lock-In. If you keep
picking up the phone and hanging up, and the line doesn't go to a dialtone,
there is a chance that you are being traced. The way to stop this is to send a
current down the line, too. First you have to find a corner in your house where
the phone wire is running along. Then you can install 'Billy Heif's Peachy
Tracer Breaker', or simply, "The DIFT box". Here's the simple schmatics for it:


          -----> RED -----> |-----/-----| >---------- RED TO LINE -------->
rom phone----->Green-----> |-----\-----| >----------Green to line ------->
         ----->Black-----> |-----/-----| >----------Black to line ------->
                           |     \     |
                           |    /  \   |
                           |  +      - |

                           Tracer Breakes

       Where you see the plus and minus, you hook up a big 6 or 12 volt battery.
Make sure you put a switch in there somewhere, so you can switch it on fast.
Hook the + and - to all the lines going out. I think that will work, I am pretty
sure. Try testing it out first. While you are talking to one of your buds, click
it on.

                      Chapter Two : Manual Tracing
        Manual tracing is just following a line back to its source. I am not
talking literally, jut following it from circuits. This takes a HELL of a long
time, like 10-20 mins or more. The only way to prevent this is to make your
calls short and sweet,
so they don't have time. Of course, if you get Locked-In, you should click on
your DIFT box for about 30 seconds.

                   Chapter Three : Time Syncro Tracing
        Time Syncro Tracing is very simple. Let's say Bob Retard is getting 100
prank calls a night (From those guys who wrote "Anarchy Phone Pranks I,II,III,
IV"). Now Bob calls up the phone company, who sends out a techie with a clock
syncronized to the phone co.'s clock. When Bob gets his prank call that night,
he just hits the button that stops the clock. Then he calls the company and
tells them the time that he got the call. They run it through their computers
and come up with a call made at that exact time, and where it came from.

       This tracing is instoppable, so just don't crank someone all the time.
But if you do it on some night like Friday, when there are a million calls
going on at once, then it is pretty safe.

            Chapter Four : Automatic NumberIdentification (ANI)
        Automatic Number Identification (ANI) is a tracing mechanism available
ONLY in ESS areas. ANI works because the YUR phone co.'s computer sends a few
digital-encoded numbers to the DESTINATION'S phone co's computer. Then the
other computer, and your co.'s computer knows INSTANTLY where it is comin from.
        Ways to tell if you have ESS: (Stolen from some G-File)
          1) 911 service
         2) dialtone first at payphones
         3) call waiting and that shit
        Well, ANI is not absolutely foolproof. I guess you could make a
cheesebox to get around it or something. It would not be hard to do that.

        There was an incident back in March, 1988, concerning ANI. Some idiot
introduced the idea of the "Sprint Back Door", which gave you access to call
anywhere in the world for "Free". Little did they know that Sprint's ANI machine
was working hard, and everyone was sent a bill at the end of the month. So,
watch it with this thing. I think there used to be a number you could call, and
the thing would call you back, using ANI. Pretty sure it's gone now.

                               Conclusion
        Well, that does it for most tracing techniques. I hope you guys kinda
understood my DIFT box. If you don't, contact me through E-Mail at any of the

Answering Machine type program, where you can leave mail and crap. Ask me for
the #.
