Yup! When all the walls were open for the remodeling, I made sure to
run a second coax and ethernet cable to every location. You never
know when you might need them.

The ONT actually has three outputs - a copper pair for telephone, a
coax for TV, and an ethernet cable for internet. There's no separate
cable-modem. The only reason there's a coax going to the Verizon
router is so the router can inject program guide info for the set top
box onto the coax (or so I've been told).
Thanks for the advice!
