To quote Karl Marx, blue boxing has always been the most noble form of phreaking. As opposed to such things as using an MCI code to make a free fone call, which is merely mindless pseudo-phreaking, blue boxing is actual interaction with the Bell System toll network. It is likewise advisable to be more cautious when blue boxing, but the careful phreak will not be caught, regardless of what type of switching system he is under. In this part, I will explain how and why blue boxing works, as well as where. In later parts, I will give more practical information for blue boxing and routing information.

Now let's say you're tired of talking to your friend in Amarillo, so you send a 2600Hz down the line. This tone travels down the line to your friend's central office (CO2) where it is detected. However, that CO thinks that the 2600Hz is originating from Bell equipment, indicating to it that you've hung up, and thus the trunks are once again idle (with 2600Hz present on them). But actually, you have not hung up, you have fooled the equipment atyour friend's CO into thinking you have. Thus,it disconnects him and resets the equipment to prepare for the next call. All this happens very quickly (300-800ms for step-by-step equipment and 150-400ms for other equipment). When you stop sending 2600Hz (after about a second), the equipment thinks that another call is coming towards --> on hook, no tone -->off hook.

Now that you've stopped sending 2600Hz, several things happen:1) A trunk is seized.2) A "wink" is sent to the CALLING end from the CALLED end indicating that the CALLED end (trunk) is not ready to receive digits yet.3) A register is found and attached to the CALLED end of the trunk within about two seconds (max).4) A start-dial signal is sent to the CALLING end from the CALLED end indicating that the CALLED end is ready to receive digits.

Now, all of this is pretty much transparent to the blue boxer. All hereally hears when these four things happen is a . So,seizure of a trunk would go something like this:1> Send a 2600Hz2> Terminate 2600Hz after 1-2 secs.3> [beep][kerchunk]Once this happens, you are connected to a tandem that is ready to obey ...

    I do not actually remember when I got my first pair of boxing gloves; I just remember them being there. They were red with chewed up white elastic around the wrist section and Mike Tyson’s autograph replicated on the knuckle. They were all chewed up because when we would put on one glove we would use our mouths to put on the other glove. I do not know what intrigued me about this vicious sport, but I loved every second of it. I guess I thought that being the world champ meant that you had nothing to fear, like superman. My dad always told my brother and I about the undefeated heavyweight champ

Throughout the 1940s, they were treated as nothing because everyone used them for free labor and they did not have a voice in society.
