When I first started working for Western Electric back in 1963, I was in the program starting in 1964 learning, about digital electronic switching. Up first electronic switching system was called number one ESS Electronics, then my education continued learning all about tsps traffic service position systems, along with, ETS, electronic translator system, then number four, ESS All Digital electronic switching system, then my education continued, with the Laboratories, number five ESS the first digital fiber optic switching system. Many many years in School, learning Unix, that's the operating system for the current systems. Unlike people think mainframe computers, those are toys in comparison. 36 years service with the Bell System, they were a fantastic company, until in my opinion the breakup in 1984, by judge green. Breaking the system up into seven independent operating systems.

@royd5323 after the step central office equipment, they had number one crossbar then number five crossbar, after that they had number one ESS, electronic switching systems, at the same time we had tsps, traffic service position systems, this is what replaced the whole telephone switchboards or as we call them in the business a boards., at the same time we had ETS, electronic translator system, electronically controlled T1 carrier systems, then we had number four ESS, that was a electronic switching system digital All Digital, then we had number five ESS, this was the first, digital fiber optic system. I hope this gives you some idea of the progress of the systems.
