Electronic Translator System for Toll Switching-System Description
B. Fought, C. J. Funk · IRE Transactions on Communications Systems · 1970
The electronic translator system (ETS), which represents the first major electronic adjunct to a toll crossbar switching system, employs the stored program control (SPC) system No. 1A in conjunction with electromechanical-electronic interface circuits to perform route translation and selection functions. The introduction of the stored program with its associated electronic speed of operation enables the ETS to provide expanded classes of service, increased traffic capacity, flexible arrangements for administering traffic routing, and aggrandized network control functions, while providing the capacity for the introduction of new features to the toll switching network.
