TL;DR — A special issue of Bell Labs’ house magazine on the No. 1 Electronic Switching System, the first stored-program telephone exchange, put into service at Succasunna, New Jersey in 1965.
Number 6 of the Bell Laboratories Record, June 1965, given over almost entirely to the No. 1 ESS, the electronic switching system whose first commercial office opened at Succasunna, New Jersey that May.
The articles trace the system’s lineage and design: an introduction by W. A. MacNair, W. Keister on the evolution of telephone switching, R. W. Ketchledge on the path from the Morris, Illinois trial to Succasunna, J. J. Yostpille on features and services, E. H. Siegel Jr. and S. Silber on the stored program, and A. H. Doblmaier on the control unit, among others. The recurring theme is stored program control: switching behaviour defined in software rather than wired relays.
What it is: a corporate technical magazine written by the engineers who built the system; a primary source for an early large-scale software project. An OCR’d scan; rights sit with Bell Labs’ successor (Nokia).
