Re: Lost power probably...
"...why arent they fitted with some sort of built in auxiliary power (barrel solar arrays or built in generator)?"
The one down the road from me has three (or four?) providers on it. Each one has a generator and an associated large underground propane tank. Of course, that tank only lasts a certain number of hours...and refueling it when there are downed trees across the road is...problematic. Wind generators, solar panels, etc don't produce enough steady power to run the site, and would require large batter banks.
All of which is why I still have a land line :-)
