ᐅ Is a telephone connection box still required?

Addition: To be honest, I don’t even know if the house has a cable connection. The previous owners had TV via satellite and internet through DSL from Telekom.

The wiring is the same in both cases, meaning I instruct the all-rounder to run duplex LAN cables from the basement to every living room and install double RJ45 outlets there.

Okay, but then the installation has to be done the same way in both cases, right?

Behind the FritzBox it is the same; the FritzBox model (usually rented with the service plan) differs between Telekom/Vodafone (telephone cable) and Kabel Deutschland (coaxial cable). Telekom typically offers you T-Entertain Triple Play.
What’s important for the electrician is that the cables are terminated with 8P8C connectors and that the outlet is suitable for this (RJ45 refers to a broad range, including some "ISDN" outlets which are wired as 8P4C). I would recommend using separate cables — taping the two cables together does not provide any advantage.

And when moving in, I will decide between the two options. Right?

Correct. The switch in the basement still requires power. The access points do as well, easiest through a switch with PoE.

Alright, thanks! According to Vodafone, the cable is available; I hadn’t considered that option before.

The description of this socket states:

"Shielded Cat.6A network outlet with two RJ45 (8/8) ports for data transfer rates up to 10 Gbit Ethernet according to IEEE 802.3an."

That should be suitable, I think.

So I’m telling the all-rounder to run duplex LAN cables from the basement to every living room and install double RJ45 sockets there.

I would approach this with a bit more planning.

- Basement: Should the patch panel, switch, and other devices be mounted on the wall, or should everything go into a network cabinet?
- Living rooms: One double outlet per room is a good start, but rooms like the TV or office might need more. This way, an additional outlet in the room can be avoided.
- Access Points: These can obviously be connected to a regular network socket or have a dedicated spot. For example, mounted high on a wall or on the ceiling. With PoE, no power outlet nearby is necessary, but these APs are usually more for enterprise settings. Ideally, one access point per floor should be used. The exact position depends on the floor plan.
- Cable routing: The best solution is to run network cables inside conduits that allow replacement. Nothing is more future-proof than properly sized empty conduits.
- Patch panel: Always choose a patch panel with a few more ports than cables arriving. Over time, you will likely want to add more connections.
- Secondary rooms: Besides living rooms, don’t forget to provide network connections to hobby rooms or the garage.
- Wi-Fi in the garden: If this is desired, prepare for it at least, because it’s not always guaranteed that Wi-Fi signals from inside the house will reach the garden.

Thank you for the suggestions. I had considered the garden; a LAN outlet is well positioned there. All cables will also be run in conduit. Network cabinet: the old basement can of course sometimes get damp, so that might be a good idea.

Or, because of possible moisture in the basement, would it be better to place all devices (patch panel, switch, router) in the utility room on the ground floor? And if so, what would the cabling need to look like—would that be more complicated?
