There are two ways they are using.
Most have the broadband on fibre and the phone on the existing copper. Some are having the fibre carry both phone and broadband, so on existing places the copper becomes redundant, and on new builds there isn't any copper going there.
So the answer is, "it depends".
Which isn't much help
