How long will your batteries last? And what about Comcast's equipment? Do they have batteries? How long will they last? Alarm system batteries should last 24 hours and then be able to sound an alarm for 4 minutes.
These are all things you don't have to worry about with POTS, hence my statement that alarm systems work better with POTS.
Exactly. This is why I'm reluctant to move off DSL to cable. The cable company nodes are powered by the electric utility, and in theory, they have batteries in them. But I know how much maintenance Mediacom does (as little as possible), and even then, the batteries aren't going to last as long as the telco CO will. It has a generator, and my ADSL circuit is CO based, so it should stay up as long as any overhead wires are up.
