   Big Class 5 switches like DMSs do not live in remote terminals of the
sort you're describing.  Those are invariably CO switches, and their 
capacity scales far beyond serving a mere outlying area.   That's like
using a fire hydrant to feed a small garden hose.

   What they do put in remote terminals are DLCs with GR.303 trunks for 
backhauling customer POTS interfaces directly into a CO switch logically.
DSLAMs are also often remote.  These shelters are fed off mains power but
typically have extensive battery plant surrounding them, and in some cases
generators depending on the size of the installation and the likelyhood of
an outage.
