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:
“The poppy that my heart was,
formed to bind all mortals,
made to strike and gather hearts
like flame upon an altar,
fades and shrinks, a red leaf
drenched and torn in the cold rain.”
—Hilda Doolittle (1886–1961)
“A Cherokee is too smart to put anything in the contribution box of a race that’s robbed him of his birthright.”
—Howard Estabrook (1884–1978)
