I will not take responsibility for your actions so dont read this
with evil intentions for the information.

Well one day I got to thinking what the fuck is DTMF so I did
some research and put together this "DUMMIES GUIDE TO DTMF" for those
of you asking the same question. So enjoy.

Ok first things first DTMF stands for  Dual Tone Multi-Frequency. Still
stumped as to what that mean? Its the noises your phone makes you dummy.
Pick up your phone and press some keys thats an example of DTMF. 

Well back in the day Bell found that thier pulse dialing system sucked.
So they relized that they could use a tone for a number but decieded it
would be better to use two tones to keep the tones from getting mixed up.

Ok so with two tones for every number and 12 buttons on the phone that 
makes 24 tones...right? Wrong because back then 24 tones would equal
one gigantic phone. So they came up with a 7 tone design that looks
a little like this.


1         2       3    a     = 697Hz
4         5       6    b     = 770Hz
7         8       9    c     = 852Hz
*         0       #    d     = 941Hz
1209Hz 1336Hz 1477Hz 1633Hz

So to put this into simple terms press one button makes two noises.

I know now your saying "Hey wait a minute Mr. JackA$$ there was never
ABCD on my phone" thats because these were to keep you from getting
access to things you arent supposed to you evil phreak you.

But wait DTMF kicks ass when used right. A two way radio and some knowledge
will get you a long way. Grab a DTMF decoder and if you come across
something odd play it back on a two way radio. DTMF does all kinds
off cool shit like open doors so use your head. You can also add
a transmitter to whatever it is your fucking with and have a talk back
system but I dont know much about that so your fucked.

Ok now you might be asking why DTMF and not cooler shit. Well buddy
DTMF was made to be affordable to save money on expensive equiptment.

So in conclusion DTMF is cheap, easy to learn, and works on any radio.

MAKES YOU WONDER WHY THE TELCO MADE AN INVENTION SO EASY TO FUCK WITH DOESNT IT?

 Well thats it and remember be a good lil phreak or else the telco man 
                       will come and get you!
