National Communication System No. 1
National Communication System No. 1 :
"A nationwide FCDA communication system, set up to minimize communication disruptions following an attack, was placed in operation in 1955. The system, known as the FCDA National Communication System No. 1, utilizes voinceteletypewriter circuits, and is engineered to use regular commercial voice telephone circuits, bypassing the regular teletype communication centers located in critical target areas. The network connects FCDA National Headquarters with its seven regional offices, alternate National Headquarters, each State civil defense headquarters, and District of Columbia civil defense headquarters, and has provision for control from FCDA Region 5, Denton, Tex., should the FCDA National Headquarters become inoperative". (FCDA, 1955 Annual Plan, 1956, p. 97)
