Johnson (eds) (Macmillan, 1930-5, 15 vols), and for planning and development of Number. 4 Electronic Switching System for long distance telephony. In 1945 he began research on two experimental switching systems: first the Electronically Controlled Automatic Switching System (ECASS), an experimental system using cold cathode gas tubes, reed switches and a special telephone set, and subsequently the Drum Information Assembler and Dispatcher (DIAD), a magnetic drum system that used vacuum tubes and semiconductor diodes.
DIAD was the first switch with memory.
In 1952 Vaughan became a supervisor in Bell Labs" Switching Research Department, leading studies on transistor, ferroelectric, and magnetic core memories in logic systems In 1955 he was named Head of the Switching Research Department and began work on the Experimental Solid State Exchange (ESSEX), a pioneering solid-state system using pulse-code modulation and a central time-division switch.
In 1958 Vaughan became Director of the Systems Research Center, and in 1962 moved to the Switching Systems Development Area. In 1968, Vaughan assumed overall responsibility for planning and developing Number.
