I have FiOS broadband only (not from Verizon). All I have is a 100Base-T cable from the ONT (Optical Network Terminal) on the outside of my house**. What that cable goes to is none of my provider's* business.
*Frontier. Actually a pretty decent company to work with. When I upgraded my defunct wireless broadband to their system, they 'stuck' me with a maintenance contract (couple of bucks a month added) but said I could cancel it once the system was up and running and I wouldn't be calling for support. So when I called to cancel it, the account sales person tried reading me all the reasons I should keep the add-on, like anti-virus, O/S support, etc. I just said, "I run Linux" and she said, "Never mind. You won't be needing all that support." Charge removed, no arguments.
**When the installer showed up and put in the ONT, he was getting ready to crawl up in my attic with their MOCA coax. I just handed him the Cat 5 cable (pulled right to the ONT location) and told him that would be all I'd be needing. He just plugged it in and left with a big grin (no crawling through the attic insulation that day).
