I have AT&T gigabit fiber. Fiber from the pole to the house, through the wall, into a transceiver, which connects to the modem via a cat5e cable.

When I had AT&T DSL, it was standard telephone hookup to the DSL point of entry, then coax into the modem.

Verizon DSL was phone all the way to the modem, IIRC. My FIOS is something that’s neither Ethernet nor coax nor phone all the way to the modem. Not sure if it’s fiber or something else proprietary, just that it’s hard wired(!)
