   Maybe it did originally, but with the advent of SLCs, there's not much   
   copper terminating at wiring centers anymore, and the space formerly   
   used for cable vaults has been repurposed.  Each SLC can serve a few   
   hundred homes, with only a couple pairs of fiber running to the CO.

   "Exchanges" meaning rate centers or wiring centers?

   SLCs also mean you don't need wiring centers all over the place; since   
   the trunk is fiber, you can run it much further than a copper loop.
