Re: OOB core router connectivity wish list

A POTS circuit necessarily terminates on a piece of gear with a specific CLLI, generally discernable at order time.

What that gear will be, and if it's in a CO with a "real" battery plant is also known in advance.

And, to tie it back on topic, the odds of a core router being in a place where its serving switch is /not/ a real CO 
are, I speculate, comfortably below 10%.

Well, let me treat this as an opportunity to learn. How does one
arrange for a POTS line ordered from the telco to travel its own
dedicated copper pair all the way back to the central office building
if the the tech tells you he only built it from one of the local holes
in the ground?
