tkind of cooperation between Bell Lab-oratories, the Operating Companies, andthe Western Electric Company, the man-lufacturing and supply unit of the BelljlSystem. Bell Laboratories couldnt sit 1back and design an ideal electronic Iswitching system. It had to design one » that would operate in the environmentof the telephone network that exists to-day. It had to be a system that wouldwork along with step-by-step, crossbarand panel systems. And it had to be ableto react correctly to any signal it mightreceive from the outside world, whetherit is a dial pulse, a touch-tone signal, ahigh voltage surge from a hghting bolt,shorted wires, or spurious signals from defective equipment. Furthermore, itmust handle gracefully all the mistakestelephone customers can make. H ESS is a job Bell Laboratories hasbeen working on for many years,and its roots go back to the late 1930swhen Bell Laboratories researchers firstbegan to investigate methods to process n!Il1l;!M!;!1M1irTltlll!l;!jl!!;!l.f!!!;;

Completed twistor memories are connected to frames in the Western Electric Columbus,Ohio plant where the Bell Systems No. 1 Electronic Switching systems are assembled. BELL LABORATORIES BIGGEST JOB digital information by electronic means.World War II interrupted that worktemporarily, though Bell Laboratoriesdid continue to employ its electronicscapabilities through its work in radarand microwave transmission. From the first investigations of elec-tronic switching, there was little doubtthat speeds could be hiked at least athousand-fold over electromechanical sys-tems. So after World War II, Bell Lab-oratories set up a formal program tobring electronics technology to bear onswitching problems. The work was doneby relatively small groups in research—some working on techniques and struc-ture that an electronic system might use,others on new devices. In a parallel proj-ect, solid state research on the behaviorof electrons in solids was leading to thediscovery of the transistor effect. P
