A fully automatic teletypewriter switching center for military use

THE United States Army Signal Corps has recently added another chapter to the colorful history of military communications. On Dec. 17, 1952 at Fifth Army Headquarters, Chicago, Ill., the Signal Corps placed in service its new teletypewriter switching center which automatically switches messages through the Army´s vast world-wide teletypewriter network. Sufficient time has passed since the system was cut into service to provide adequate demonstration that the system is an important link in modern military communications. Behind the drama of the cutover to the new system lies a story of technical progress which has kept the Signal Corps abreast of the most modern developments in communications technique. Some of the many technical and operational problems encountered in the development of this highly complex system will be told here.
