Hello, I am currently renovating my house and have a small issue with the wiring of the telephone lines and the connections.
I would like to have my internet box in my living room so that I have a permanent visual on the indicators, and to distribute from the box to 4 RJ45 sockets throughout the house (2 for the televisions, 1 for the office, and 1 for the home automation box).
I would also like to have the telephone line from the box in certain rooms.
I am not quite sure how the telephone line arrives and how the connections work, I am attaching a diagram.
In blue is the diagram I was thinking of making, and in color are my doubts...
And I also wanted to know which cable to use knowing that fiber is expected to arrive soon.
Thank you for your help
Configuration: Macintosh / Safari 9.1.3

Hi,
I didn’t quite understand whether the wall sockets and cables are already installed or not.
If nothing is installed yet, everything is possible .... :-)
If it’s already set up, it’s going to be a bit more complicated.
Given your last sentence, we’ll assume you’re still in the planning stage.
Overall, it would be better to place your box (internet box) at the patch panel, but that's not your choice.
First,
do not install RJ11 wall sockets, use RJ45 everywhere.
If at the location where you place your box, you install 2 or even 3 wall sockets for fiber to your patch panel, you shouldn’t have any issues.
At the patch panel, plan for:
a telephone splitter (a spider cable can do the job) and a gigabit switch for the Ethernet network, minimum 5 ports, 8 ports would be better.
Then, patch cords, and everything should run smoothly.
If you have an ADSL box:
3 RJ45 wall sockets for: one ADSL connection to the box, one Ethernet network to the switch, one to the telephone splitter; the first and the last can be grouped by adding two pair splitters.
Or even all 3 with two splitters like this:
But if you can, it’s better to plan for 3 sockets directly and 3 cables.
If you have a fiber box:
3 RJ45 wall sockets, if the ONT (fiber equipment before the box) is not present (or integrated into the box), you won’t have a choice, you will need to place the box where the fiber arrives, so at the patch panel, unless you bring the fiber near the box in the living room (not recommended).
one RJ45 from the ONT to the box and one from the box to the switch, plus one to the telephone splitter.
if the ONT is integrated or there is no ONT, 2 sockets will suffice: one to the switch and one to the telephone splitter.

Thank you for your quick response,
Indeed, it's under study, but we have already installed the conduits. We just have to run the cables.
What is the purpose of connecting the box to the patch panel?
I would like to create a diagram to see if I have fully understood your explanations, but I'm going on a business trip for 2 days; I will try to do it if I have the time.
First of all, to avoid adding a switch if we have few sockets and to connect the phone splitter directly as well.
In short, just one cable to the living room for the TV box instead of three.
