Commissioning of the network installation

Normally, there is always a color scheme for the A and B variants on the back. If the sockets are already installed, ask your electrician which variant he used, otherwise there's a 50/50 chance.

I always chose A because the wires lie next to each other as they were twisted. If necessary, you can also check this on a socket.

So I would refrain from crimping. Placing it on the patch field with an LSA, on the other hand, is really very easy. Especially because it is also easy to correct.

So today I took a photo of the telephone connection again? Is it now prepared so that I just have to put the plug on the cable and then connect it to the Fritz!Box?!

Unfortunately, I cannot see from the picture what is wrong with the cable. You can definitely see the [APL] there; was a telephone socket installed next to it as well? You would then have to plug the cable from the Fritzbox into this (if the phone is running through it), otherwise, a splitter must be installed in addition to the telephone socket.

There probably won't be any more splitters because of the digital connection

Therefore the note on how he tries to connect something. There are still areas in [Dtl.] where old connections exist.
