That's the usual use of a UPS, but I'm having a difficult time imagining an ISP
providing one gratis for the sole purpose of letting end users keep their
machines on 24/7. That just doesn't make any sense, unless this is like those
toasters people used to get when signing up for a new insurance plan. I
speculated that it might be there for the purpose of protecting ISP equipment
because a UPS does more than just provide backup power -- it also acts as an
effective filter to keep power steady, with no brownouts, blackouts, or spikes
getting through to the computer equipment. It may be that the ISP wants to
protect its own equipment by inducing the end user to use a USP to protect it.
I sincerely doubt using a UPS as a battery backup is the only reason the ISP
would give them away with service contracts. It just doesn't make any business
sense.
