Well written.
In my last two jobs, I provided IT support to ~200 user companies. Of course phone service is essential to any business. I remember staying at work until 11PM one night while AT&T repaired our PRI that went completely down. Lots of old cable in the area.
We had a group of POTS lines dedicated to dialing into burglar alarm panels for programming. We had issues dialing out and entered trouble tickets on two of those lines. Mother Bell sent two technicians, at the same time, to the same building, one for each ticket. Spoiler: only one human can fit in the phone closet at a time!
At my current shop we hae 5 lines going into a Norstar 616. One day, we started having bizarre issues. Lines were ringing randomly, bleeding over onto one another, could not hear customers, etc.
AT&T came out and replaced an underground splice case that was completely rusted through.
My personal favorite, it takes two technicians and two vehicles to make (1) key copy.
