Repeater production for the North Atlantic link

Production of the submarine telephone cable repeaters, designed to have a minimum trouble-free life of 20 years, required many new and refined manufacturing procedures. Care in the selection and training of personnel, manufacturing environment, inspection, and testing, were of great importance in the successful attainment of the ultimate objective. Although quality of product has always been of major significance in Western Electric Company manufacture, building electronic equipment for use at the bottom of the ocean, where maintenance is impossible and replacement of apparatus extremely expensive, required unusual manufacturing methods.
