  I would suggest contacting the LEC[1] and seeing if they'll extend
the demarc to your phone room.  That means they move their CPE[2] out
of the demarc and into your phone room.  That would likely mean
running additional fiber from the demarc to the phone room, which
won't be cheap, but will be the most reliable solution.

  Alternatively, see if they can change the line card/configuration in
the existing CPE at the demarc over to "outside plant" type[3], and
then put NIUs[4] in your phone room as an extended demarc.  That would
let you run the signal over your existing copper.  Outside plant runs
go tens of thousands of feet.

  Goal here is to bring the telco signal as close to your equipment as
possible, eliminating the question of customer-responsibility
repeaters/etc., entirely.

customers.
