The back up power for new Fios installs in NYC consists of an optional battery box that holds 12 D cells. There is a manually operated switch on the box that is turned on in the event of a power failure.
I have the first ONT that Verizon used for FiOS installations. It is large and made by Tellabs. The battery backup uses a 12v sealed battery as opposed to the multi D cell.
RCN salespeople stop by the house once in a while looking for us to switch. They claim that RCN now has their own fiber in our area. A quick look at the utility poles along the street doesn't quite support that statement.
