- Red Box Plans by the Jolly Roger
-
- Red boxing is simulating the tones produced by public payphones when you
- drop your money in. The tones are beeps of 2200 Hz + 1700 Hz
- Nickle = 1 beep for 66 milliseconds.
- Dime = 2 beeps, each 66 milliseconds with a 66 millisecond pause between
- beeps.
- Quarter = 5 beeps, each 33 milliseconds with a 33 millisecond
- pause between beeps.
-
- There are two commonly used methods being used by Phreaks to make free calls.
- 1. An electronic hand-held device that is made from a pair of Wien-bridge
- oscillators with the timing controlled by 555 timing chips.
- 2. A tape recording of the tones produced by a home computer. One of
- the best computers to use would be an Atari ST. It is one of the easier
- computers to use because the red box tones can be produced in basic with only
- about 5 statments.
