A red box is a phreaking device that generates tones to simulate inserting coins in pay phones, thus fooling the system into completing free calls. In the United States, a nickel is represented by one tone, a dime by two, and a quarter by a set of 5 tones. Any device capable of playing back recorded sounds can potentially be used as a red box. Commonly used devices include modified Radio Shack tone dialers, personal MP3 players, and audio-recording greeting cards.
Famous quotes containing the words red and/or box:
“All those girls
who wore the red shoes,
each boarded a train that would not stop.
Stations flew by like suitors and would not stop.
They all danced like trout on the hook.
They were played with.”
—Anne Sexton (1928–1974)
“Appeal. In law, to put the dice into the box for another throw.”
—Ambrose Bierce (1842–1914)
