Professionally I use APC SmartUPS, while some would argue they are not Telco 
grade, they don't carry the telco price tag.

Two features with respect to alarming that many using SmartUPS are not aware of, 
is not only can the alarm be disabled, it can be set to only go off at "low battery", or 
"power fail + 30".  

A SmartUPS-700 runs one PC and a little network equipment fairly well.
