Verizon tells you that the battery only backs up the phone, but my Alcatel-Lucent I-211M-H ONT keeps both phone and internet powered for hours.
I also have an Alcatel-Lucent I-211M-H
I've unplugged it, and ran a stopwatch test on numerous occasions, and the Ethernet and TV connection lasts exactly 15 minutes on the battery alone.
More than 5 min, but not hours.
Oh, and I do have an APC SU750XL UPS that the ONT and Router are always plugged into.
Long UPS run-time isn't really an issue though, as long as the generator fires up..--
