Re: VoIP isn't POTS....

That statement is not true. Comcast digital voice comes with a battery back up in the MTA, and has battery back up on the main lines, and will also work with alarms, fax, dial up modems, etc....
Yeah, but how long does the battery last? I'll bet not more than 8 hours. That's fine for short term outages but what happens when the power is out for 2 or 3 days such as after a big storm that knocks down a lot of power lines.

The advantage of line powered systems is that the central office usually has diesel generators that can last a week or more.
