This is the most confusing thing to research. I want to eliminate the battery backup on the ONT (I understand what I'm doing on that front) and connect a UPS unit instead. I cannot get a clear idea as to what size UPS I'd need to run for a few hours in the event of an outage. I want to connect ONT, Quantum router and a 4 port switch all are co-located. I have a POTS line as well. That's it. Thank you!
