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:
“With the old kindness, the old distinguished grace,
She lies, her lovely piteous head amid dull red hair
Propped upon pillows, rouge on the pallor of her face.
She would not have us sad because she is lying there,
And when she meets our gaze her eyes are laughter-lit,
Her speech a wicked tale that we may vie with her....”
—William Butler Yeats (1865–1939)
“I am no source of honey
So why should they turn on me?
Tomorrow I will be sweet God, I will set them free.
The box is only temporary.”
—Sylvia Plath (1932–1963)
