Then just check which cable is installed between the sockets. Really only 2 or 4-core, or maybe already CAT cable, where not all wires are connected.
Connection box in the wall - What kind of connections are these?

ok, good idea. Result see picture. Two gray cables come in here. From one, a black and a red cable go to the socket. Next to it, a yellow and white cable can be seen unused. From the other, a blue and a red cable go to the socket. Next to it, 5x white and respectively 1x brown, black, blue, yellow, and green are unused. Can you make use of that? Regards

Shame on me, you are right...

No, these are apparently the communication cables commonly used 30 years ago. Even though you could possibly connect 4 pairs of wires to RJ45 sockets here, the crucial feature of a CAT network cable is missing: special shielding of the wire pairs and the entire cable. What you would get is a network wiring in 10Mbit condition, which is useless because current routers and PCs will refuse anything below 100Mbit.Can you do anything with this?

Yes, if there are empty conduits. Then you can still use the cables as threading aids for the new CAT cables.No

Oh dear. That was botched by a hobby installer. "Internet coming out" can’t work here because it first has to somehow get into your home network, and then because of the socket wiring. These are ISDN sockets, which you can also see from the terminal strip that only has 4/5 and 3/6, so 1/2 and 7/8 are missing. For Ethernet, you would need 1/2 and 3/6 (or all four pairs for Gigabit Ethernet). Forget the nonsense about shielding making it unusable; I work professionally in the industry and have seen more perfectly functioning internet over doorbell wires in practice than even the well-informed ITK reader can believe.
You can still use the socket insert if you want to use it for analog phones, which are by no means obsolete yet—unlike ISDN. The cables you see are two different ones, and someone must have had a reason for that, because actually only the "smaller" one of the two would have been necessary here. The questions of where they come from (and by which route(s)) would be worth investigating.
The cables are, on the one hand, classic telephone cable, of which only the first pair was used (red/black), and a 6DA cable, also TK (or for moderate demands also IT) cable. You can keep the first as a reserve behind the socket; you can use the larger cable (for Gigabit Ethernet only for one socket). The pairs belong together as follows: red/blue, white/yellow, white/green, white/brown, white/black, and white/blue, cf. e.g. tocker (de). Together these are six twisted pairs, of which you only need four for one socket. Mixing with the other would also be possible, but that wouldn’t be my first choice.
