The C.R.M. 114 Discriminator is a fictional piece of critical radio equipment in Stanley Kubrick's film Dr. Strangelove, the destruction of which prevents the crew of a B-52 from hearing the recall code that would stop them from dropping their hydrogen bombs on the Soviet Union.
Real-life parallels
In Peter George'snovel, Red Alert, which was the basis for the film, the device is called the CRM 114. Peter George was well-informed - under the U.S. military Joint Electronics Type Designation System, CRM is the designator for an air-transportable cargo radio maintenance or test assembly, and 114 is a feasible series number. If the CRM 114 were an actual U.S. military item, its official number would be designated as AN/CRM-114.
To ensure the enemy cannot plant false transmissions and fake orders, the CRM 114 is to be switched into the receiver circuit prior to receiving attack or attack cancellation orders. The three code letters of the period are to be set on the alphabet dials of the CRM 114, which will then block any transmissions other than those preceded by the set letters from being fed into the receiver.
Prior to the introduction of addressed digital communications, some real-world analog communications systems performed a function very similar to the fictional CRM-114. Some aircraft radios used SELCAL, which muted the receiver unless an assigned tone was received. Ground mobile radios used a similar system called CTCSS.
