Some areas don't have a (working) power backup. Expect to lose dial tone if your power is out. New phone modems don't even have a place to insert battery in. It doesn't mater since 99.99% of people no longer have one of those simple corded phones that get power via phone cord so when the power goes out their phones lose power too.
That's because Mediacom does next to no PM work.
