Like everyone has said, contact the service provider. Each one has different ways they install the service.

Here in Ontario, in this area there are 3 providers that have the territory divided up between themselves, some of it overlapping. The telephone company advertises fibre, but it is only to a service box down the block or even several blocks away and it switches to telephone wires. In our old location it changed to a 50 year old corroded cable with lots of noise. They wouldn't change it, only try another pair of wires in the cable. The cable company uses their TV cable to feed the internet.

Where we are now, the service provider offers fibre, and installs a fibre line right into the house, with an excellent signal. So you need to find out what your local service provider will provide and how they will connect you up.
