Just a little bit of semi-useless info.
I've seen a couple reference to the fact that the backup battery is ONLY to provide phone service in the event of an outage.
Maybe not so.

I replaced a ceiling fixture and had to kill the power that my FIOS setup is wired from. The bright MD-DVR box continued to shine it's super bright TIME when the power was cut off, so thus the battery provides more than just PHONE backup. Nuts, I should have checked the router lights but my guess is that it remained powered because when I was finished I had not lost the GUIDE channels, so I think my system remained connected to the internet and the router and the ONT likely remained powered byt the battery.
