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.
Red Box are a British pop group founded by Simon Toulson-Clarke and Julian Close. Active from the early 1980s to the early 1990s, they scored two UK Top Ten hits with the singles "Lean on Me (ah-li-ayo)" in 1985 and "For America" in 1986, both of which were included on their debut album, The Circle & the Square.
Red Box returned briefly in 1990 with the single "Train" and second album Motive and again in 2010 with third album Plenty released in October 2010. The group is now led by singer-songwriter Simon Toulson-Clarke with a third line-up of supporting players.
Ministerial boxes, informally called red boxes, are used by ministers in the British government to carry their documents. Similar in appearance to a briefcase, they are primarily used to hold and transport official departmental papers from place to place. They are not to be confused with the despatch boxes from which speeches are given in Parliament, although ministerial boxes are also referred to as "despatch boxes" in government documents.
