A 2600 Hz tone is used to break a line and seize the long distance trunk on
a bluebox. The KP1 is used as a start signal on a national call. The KP2 is
used as a start signal on an international call.
The ST stands for Start Transmission and KP stands for KeyPulse.
A bluebox operator first dials an
800 number and when it begins to ring, he presses 2600 hz and then punches
out his number on the bluebox in the format of KP + XXX-XXX-XXXX + ST. On the normal Touchtone keypad, there are the 0-9, plus the # and *. There can also be modifications to a touchtone phone to make it produce the AUTOVON tones. These four tones are usually labeled as A, B, C, and D. These four tones can be used to obtain free long distance also. The four keys are referred to as follows:
A-Flash B-Flash Override Priority
C-Priority Connection and D-Priority Override.
Pink noize is a masked 2600 Hz tone composed of 2600 Hz and 3000-3700 Hz tones mixed. This is used to avoid detection of 2600 Hz on the line by blue box detection schemes.
