The issue wasn't diversity, it was "is my POTS on Central Battery"; sorry for the comparative red herring.

Typically when I hear statements like that, it's that the tech built
(strung aerially, trenched through ground, or through buried conduit)
from a pedestal or other copper splice point to the customer premise. 


I would only expect this to go to the nearest remote terminal, or
central office if there is no remote terminal. In a lot of (rural)
cases, there is no direct copper between most houses and the central
office, instead they have to (in most cases, depending on what copper
cabling is available you are only able to reach one remote) cable you
to the closest remote that has equipment, where you are aggregated and
back-hauled (typically via fiber, but sometimes by T1) to the central
office. 


If someone wanted completely physical diversity, up to the point of the
CO, you would have to ask (likely a few times, and possibly being
escalated to an engineering department of sorts) if your new POTS line
can be homed to a different remote, or directly to the CO, ideally on a
different physical cable route, assuming your goal is backhoe
diversity. 


For a business line, they may be willing to work with you on diversity
requirements. 


About the only way to guess if you're connected to a RSU or directly to
the CO, you would have to know where the CO is, guess the approximate
copper distance to it (which may involve guessing the approximate path
the cable goes) and then hook up some equipment to your POTS line that
measures and estimates the distance of that copper pair. Then you can
guess where you might be connected to.

or to an RSU? 

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?
