Lol I was a tech guy waaaay back in the day. Telecom high tech was teletype which then morphed into analog data feeding a controller to multi point CRT terminals and low speed printers. Cell service was only a dream and mobile phone was actually a radio feeding a phone head with the signal going through a base station hence the need for a 2nd class radio license. After my mentor retired I was the only outside tech to hold the license. Some toll guys worked the microwaves also held the license. I transitioned into Management and got away from the tech end in the mid 80s. I actually liked installing and repairing equipment better than managing people but my path was forged.
