As most of you know a touch tone fone produces a sound
when a key is pressed. What some people don't know, however,
is that this tone is actually 2 sounds. This system is
referred to as DTMF (dual tone multi-frequency). Here is a
list of both tones' frequencies :
KEY FREQ. #1 FREQ. #2
--- -------- --------
1 697 1209
2 697 1336
3 697 1477
4 770 1209
5 770 1336
6 770 1477
7 852 1209
8 852 1336
9 852 1477
* 941 1209
0 941 1336
# 941 1477
These freq. are measured in Hertz.
Red Boxes:
Here are some money frequencies to use with the red box.
Although 1 piece of real $ is needs to be sent first the
red box duplicates the rest. ms=millisecond 1700hz & 2200hz mixed together
nickel-66ms on (1 beep)
dime-66ms on, 66ms off, 66ms on (2 beeps)
quarter-33ms on, 33ms off (repeat 5 times)
Silver Boxes:
Sliver boxes change the 3,6,9,# keys on a touch tone
fone to A,B,C,D As with a regular key these use DTMF.
KEY FREQ. #1 FREQ. #2
--- -------- --------
A 697 1633
B 770 1633
C 852 1633
D 941 1633
These freq. are in Hertz.
Green Boxes:
A disadvantage of these is that they must be used by the called party.
The freq. here should be used only after a signal is sent to alert
the MF detectors at the CO. This is done by sending 900 + 1500 Hz or
a single 2600 Hz (90 ms) tone followed by 60ms of silence and then
the tone you want for at least 900ms. Here are the freq. in Hertz :
That concludes this little journey into the world of
fone phreaking...hope this helped someone out there.
