In telecommunication, a hotline (also called an automatic signaling service or off-hook service) is a point-to-point communications link in which a call is automatically originated to the preselected destination without any additional action by the user when the end instrument goes off-hook.
Hotlines cannot be used to originate calls other than to preselected destinations. Various priority services that require dialing are not properly termed "hotlines."
Perhaps the most famous hotline was the so-called "red telephone" that linked the White House with the Kremlin during the Cold War. It was established in 1963 after the Cuban missile crisis made it clear that reliable, direct communications between the two great nuclear powers was a vital necessity. It was rumoured that this link was encrypted using the theoretically unbreakable one-time pad system.
- Derived from Federal Standard 1037C.
