No RJ45 socket

Hello,
I just moved into an apartment, where there is an RJ45 wall socket in every room. My problem is that I can't find the switches in the electrical panel; I have a DTI box with only one Ethernet socket on it, but that's it for sockets...
Thank you!
Best regards,
Léon.

Hello,
if you were to put some photos of your communication cabinet it would help, but from your description it’s likely that you only have the DTI test socket as an RJ45 in this cabinet.
You will need to make some modifications if you want to distribute a somewhat normal Ethernet network.
Also,
there is no switch in a communication cabinet, unless you install one, the sockets you are talking about are called a patch panel, not a switch, it’s not the same, it’s just the end of a cable.
The cable in question must be connected directly to the DTI from what you say.
Check this forum, you will find plenty of questions in the same situation, quite common actually.

Here is a photo!
Thank you for your response and for the corrections. Looking through the forum, I didn't see many cases where the patch panel was missing, which is why I took the liberty of posting. Moreover, as a tenant, I wonder to what extent I can install this myself, and finally, if in the worst-case scenario, I can't tinker with the cables to connect the wall socket of my box to the wall socket of my office.
Thanks!- Hi,
see this discussion
In fact, if you don't want to invest too much, there is a way to connect two sockets together, but I think you would be better off negotiating a proper installation with your landlord; it can only increase their property value. - Afterwards,
there are two strange things in your photo:
a cable that comes out of a sleeve to go into another, and a cut cable that is not connected, there has been some tinkering going on around there....

Hello,
Apparently your DTI box has 3 lines.
So, one telecom network input and 3 outputs. Each output must surely power each room.
From there, you can place your internet box in the room you want, however you cannot use the other sockets.
If you want to use all the sockets, you absolutely need (as brupala said) a communication cabinet. From there, place your box in the electrical cabinet and power the communication cabinet which will then supply each room.
Be careful, I am not an expert in ethernet cables but I don't think you can use one ethernet socket for multiple devices. Especially for TV (for my part I have a console + a Philips hub bridge + the internet TV + my Verisure alarm, so I placed the box next to the TV and I do not use the sockets in the bedrooms).

Hello,
Curious... it seems that a cable is cut clean (black arrow) and that a socket has been connected to another with a cable
drawn from one socket to another. (Red arrow)
Could we have a photo with the DTI box open and the two antenna cables passing
to its left slightly shifted to the left in order to see the inside of the DTI on one hand and this cable that seems cut on the other. -
Here! No cut cables, it's an ugly optical illusion. It does look like quite a mess... But when I see this, I wonder if by connecting the right wires, there’s a way to just link two sockets (box -> office), as if it were "just one cable".
In any case, thank you for your help!-
Ok...
In fact, the "disconnection" was due to the inscription on the cable that seems to be the incoming cable and comes out of the DTI with 4 cables
and I deduce that there must be 5 sockets in the apartment which would explain the double cable in one of the conduits.
This wiring is only for telephony... for internet, the 8 wires need to be connected to the sockets...
To be checked, but in the RJ45s in the rooms there should only be 2 wires connected.

There are only three sockets and three wall outlets; I will take one apart and keep you updated.
-
3 rooms and 3 wall sockets!
Yet there are, unless I'm mistaken, 5 cables around the DTI - 1 incoming cable labeled ALIM and 4 others that come out.
Not to mention the additional cable that is duplicated in one of the conduits and then goes into another.
Would there be any T-jacks in addition to the RJ45s in some places?

Hello.
Since you are renting and if the owner of the apartment refuses to do the work, you will need to carry it out knowing that what you do will have to stay in place (so the owner will be happy with your work) or run RJ45 cables along the walls.
.
There is also the availability of powerline adapters, which have the great advantage of being plugs that can be easily plugged in and removed, so when you move later, you can take them with you.-
it wouldn't be smart to add cables on the walls when there are already some inside and it's just a matter of putting proper plugs at the end.
As for the powerline adapters... Well, that's fine only if there's really nothing at all.
But if we just have some patching to do, that's not clever either.- However, not everyone is allowed to know how to wire a network. There are people who would never dare to venture into this kind of work, and there's no need to be clever to understand the problem. Some tinker, others work, each to their own profession. So all solutions can be good, it's up to each person to see noon at their door in light of their knowledge and/or their wallet.

If you just want to connect two sockets together,
you can install this type of connection to link them together by wiring them correctly like this:
to this module and the corresponding wall sockets.
You also need to find the two correct cables that go to these wall sockets.

and ... There you go!-

We start with the objective, which is to do this basically:
but without a patch panel, just by replacing the cord with the above product.
But I repeat, the ideal would be to do it like in the diagram; it’s cleaner and more scalable.
To identify the cables, you need a multimeter in ohmmeter mode, preferably with a buzzer, it’s simpler, often represented by a diode.
In any case, you can quickly identify it: it beeps when the probes touch.
Take an RJ45 cord that you cut in the middle and short-circuit the central pair (blue/white-blue in principle), insert it into the wall-mounted RJ45 to be found.
With the multimeter at the communication cabinet, we will test the continuity of the yellow/orange pair if the wall-mounted RJ45 is wired as above. The cable must be in the air, disconnected from the DTI.
When it beeps, it's the right cable ....
Not rocket science, right? -
