FIOS is installed in each house with a backup power supply that will provide up to 8 hours of backup power for voice calls. Your data or FIOSTV will cease to function until full power is restored to the ONT. One way to extend this time and keep data and FIOSTV going is to hook the ONT power plug into a larger UPS system. This will power the ONT for a longer time and keep all services going depending on usage.
