  So what are you using?  AC or DC?  If you are not on DC, I would
  switch.  Maybe you would have better luck.

You took the words right out of my mouth.  -48vDC is *so* much cleaner
and less troublesome than mains AC (or even upsed AC) that I urge all
my clients to use it for *everything* whenever it's available.

Typically telco setups have about 30min-1hr of AC UPS capacity and
4-6 hrs of 48V battery capacity.  Last time i was at MAE-East it
didn't have any backup AC power and a nice DC setup.

BTW, the cheap solution for DC hookup would be using a power inverter.
