[Solved] Connecting Vodafone Router to German Telephone Socket: Cable Setup & Activation Issues

Hello. I am in the process of establishing a permanent internet connection in Germany and I have a problem because I cannot connect to the router according to the vodafone operator, everything is activated and the signal has been turned on. I decided to unscrew the socket and I see that two cables are connected and two are not my question is whether it should be connected or otherwise. Thank you in advance and I'm sorry how I set up the topic in the wrong department.

Is the phone connected to this socket working properly?
What service is this? What equipment? Filter installed?

I don't know if the phone works because I don't have one and I don't know if it was before. The vodafone dsl service 16. There was no filter in the set with the router and there is no filter in the connection description.

This plug in the photo from the router? Give a picture of the back of this router. What do you have there .

You came from the telecom and connected.
Greetings.
