Any electricians in the house?

^^Telco^^ LOL, I think it was Newport, WA, when I worked for the Motorola outfit. The jail/ SO/ 911 dispatch was somewhat complete, and we were up there tying up some loose ends and yanking out abandoned cables, "Several" little "things."

One was the 911 director showed up at some point and said something that amounted to she was unhappy with the time we were spending, why can't we just cut those cables and pull them out. There "just happened" to be a vacuum cleaner against the far wall, and an extension cord. I tried to explain to her that "all those cables" (potentially) were just like that vacuum/ extension cord. Some of them were still connected to something at the other end.
===============================
At some point I was pulling cable out of the overhead runs. Up on a ladder with my head up above the ceiling tile, dropped ceiling. Here shows up a piece of coax, connected to a UHF (450mhz) two way radio that someone had cut. IT WAS SPLICED WITH WIRE NUTS
================================
In the course of chasing down the old cables, It "just happened" a local telco guy was there that day, so he and I teamed up to run some of this down. It turns out, example, that in the several-times remodeled building, one phone terminal was in a CLOSET.. I'd never found it except he knew it was there. Moved a bunch of junk, mop buckets, and here's a metal box

==================================

He and I ended up in the phone room, which, due to remodel, was surrounded by "the jail." We are back there chasing stuff and the room goes dark. AND we CANNOT GET OUT because the electric locks are controlled from dispatch, which was communicated via intercom, and neither of them now worked. No cell coverage there in the late 90's. Fortunately I had my trusty mini-mag--the only lighting between us. He found an outside line, called dispatch, and got someone to come back with keys and let us out

Turns out they were testing the emergency generator, HERE IS THE DEAL

Of all the expensive equipment, remodel, engineers, architects, etc, IT TURNS OUT that the lamp over the pool table and the kitchen coffee pot were both on the uninterruptible power supply (Bank of batteries the size of two coke machines) and of course the genset. BUT THE ELECTRIC jail locks AND THE BUILDING INTERCOM had not been wired into the transfer
