ᐅ Wiring for Telephone Connection / LAN

Hello fellow home builders,

We are currently planning the electrical installation for our new build, including LAN and telephone connections. I have already read a lot but haven’t found a satisfactory answer for our exact situation online. Your assessment would be very helpful:

We have a utility room in the basement where, naturally, the phone line from the telecom provider enters. If I understand correctly, a telecom standard telephone outlet (TAE socket) is always installed there? And the line belongs to the telecom provider up to that point?

We want to install the network wiring in the utility room, but the router is planned to be located on the ground floor. We have a spot where we are quite sure there will be Wi-Fi coverage where it’s needed. So we planned to install a power outlet and four LAN ports there. One port would bring the signal from the TAE socket in the basement to the router, and three would go back down to the patch panel/switch. Essentially, I would prefer to run a cable from the telephone outlet to the patch panel and then up to the router.

My main question is: Is this possible? Can a network cable carry the two-wire DSL signal, and if so, which adapters would I need? How should the two wires be connected to the patch panel?

Or is our electrician right in saying that we need an (additional) TAE socket where the router will be? According to him, everything else would be complicated and require a custom cable... We would actually like to avoid having a TAE socket on the ground floor, both for aesthetic reasons and flexibility (maybe the router will be moved at some point).

Thanks for your help and experiences...

Good luck, Björn

Besides the LAN wiring, we are currently considering running a telephone cable to two locations in the house (kitchen + office).

That doesn’t make sense... install LAN everywhere instead... then you can use it for telephone if needed... the other way around doesn’t work... so you might end up with cables that are useless.

If I place the router, for example, in the office and connect it via the telephone cable, I could connect the LAN cable at the LAN port, which runs back to the house’s main distribution room, and then supply the rest of the house with LAN via a patch panel.

Just run 1-2 extra LAN cables to the office and that’s it.

Are there phones now that can connect over Wi-Fi, or do I still need a telephone cable running from the router to the phone’s location?

There have been DECT phones for decades, and they work very well inside and around the house, alongside your Wi-Fi.

No one installs traditional telephone cables anymore. Nowadays, a "structured cabling" system is used, meaning network cables are installed everywhere, fully wired with all eight conductors. Even if later an analog phone only uses two conductors, it doesn’t cause any harm. IP phones are technically data devices too—even when handling "voice service," they use all conductors for Gigabit connections.

Connecting phones via Wi-Fi only makes sense for mobile handsets, meaning when you want to use a mobile phone at home. Cordless home phones work better with DECT technology. A DECT base station can also be an IP-DECT base, meaning the radio link between base and handset uses DECT (or cat-iq protocol), and the connection between the base and the phone system is IP-based. This IP-DECT base can also connect to the phone system or router via Wi-Fi.

If a Fritzbox is positioned unfavorably for direct registration of handsets or Fritzfons, usually an "ISDN"-DECT base is used on the FON S0 interface.
