Explanation:

The Cuban Missile Crisis led to several significant changes. The White - House and Kremlin installed a hotline (improved communication system) to quickly communicate and avoid misunderstandings. The U.S. and Soviet Union reached an agreement to remove the threatening missiles. Also, the Limited Test Ban Treaty was signed later as a result of the heightened awareness of nuclear dangers from the crisis. Blockades were already in place during the crisis and the two super - powers did not increase nuclear production and testing as a direct result of the crisis.

Answer:

The White House and the Kremlin installed an improved communications system.
