Fibre queries

[#1]

I'm considering upgrading to Essentials Fibre and have the following queries:
1)  I've just had my phone line diverted to a more direct point of entry and a new line socket fitted. Will the new master socket plug into this or replace it?
2)  Will the new master socket have a socket for my home phone which is currently plugged into the same line socket (via filter) as my modem?
3) Does the new modem/router come with a new Ethernet cable to connect to my pc or can I use my existing one?
Sorry if these are daft questions!

1. It depends - either replace it or just add a new filtered faceplate
2. Yes
3. the modem has its own cable to the phone socket and the router does come with a cable to connect to the modem and probably another shortish one for going from the router to the computer but you can use your own there with no problems
