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 i t 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 P hone 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 curre nt down the lin, 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 Bre aker', or simply, "The DIFT box". Here's the simple schmatics for it: -----> RED -----> -----/----- >---------- RED TO LINE --------> Fromuphone----->Green-----> -----\----- >----------Green to line -------> ----->Black-----> -----/----- >----------Black to line -------> \ / \ + - Tracer Breaker 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 loterally,just 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 yoir DIFT rox yor ubouf 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,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 m`´´e`´ime`´hat`¨e`§ot`´he`£alln TØey äun 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. B ut 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 Number Identification (ANI) Automatic Number Identification (ANI) is a tracing mechanism available O NLY in ESS areas. ANI works because the YOUR phone co.'s computer sends a few di gital-encoded numbers to the DESTINATION'S phone co's computer. Then the other c omputer, and yo ñ…ur co.'s computer knows INSTANTLY where it is coming 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 cheesebo x to get around it or something. It would not be hard to do that. û 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 any where in the world for "Free". Little did they know that Sprint's ANI machine wa s working hard, a nd everyone was sent a cill 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 th ing would call you back, using ANI. Pretty sure it's gone now. û Conclusion Well, that does it for most tracing tectniques. I hope you guys kinda un derstood my DIFT box. If you don't, contact me through E-Mail at any of the boar ds at the end of this file. I have my computer answer sometimes, with an Answeri ng Machine type program, where you can leave mail and crap. Ask me for the #. -> Disclaimer <- Like every piece of great literature, comes this. I don't take responsib lity for any of YOUR fuck ups. If you get busted with your DIFT box, it IS a fed eral offense.
