Red Box (phreaking)

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:

    Every one of my friends had a bad day somewhere in her history she wished she could forget but couldn’t. A very bad mother day changes you forever. Those were the hardest stories to tell. . . . “I could still see the red imprint of his little bum when I changed his diaper that night. I stared at my hand, as if they were alien parts of myself . . . as if they had betrayed me. From that day on, I never hit him again.”
    Mary Kay Blakely (20th century)

    He had put, within his reach,
    A box of counters and a red-veined stone,
    A piece of glass abraded by the beach,
    And six or seven shells,
    A bottle with bluebells,
    And two French copper coins, ranged there with careful art,
    Coventry Kersey Dighton Patmore (1823–1896)
