NOC technician. We monitor fibre optics, telephony, environmental (power, temperature, fire etc) of our buildings, and pretty much any odd ball thing you can think of like air conditioning. We also oversee a lot of other misc stuff like after hours business 611 and such. When there are mass power outages due to storms we'll coordinate sending generators etc... We used to monitor CDMA cellular but they took that away. It was actually kinda a pain anyway because we did not monitor HSPA yet we were still responsible for dispatching techs, so we were basically the middle man. All of that is gone now. We still monitor CDMA for fun as long as we can login to the app, as the other group keeps dropping all the cell sites and we just laugh. We did a better job.
Basically we make sure service does not go down. If you ever wonder why your phone still works when power goes out, it's because all these sites have batteries, and we make sure they don't get depleted by sending generators as required. Some of these sites are buildings, while some are small cabinets on the side of the street, usually called RCUs. (remote concentrator units I think is what it stands for, but I'm just taking a wild guess).
Basically if everything is working my job is fairly lax, but if there's lot of stuff down it can get hectic. Depending on overtime, and what shifts I work it's very good pay. I actually cleared 80k last year. I'm at 70k this year so probably wont quite clear that much but still a very good pay.
