Installing Router inside Electrical Closet and Hacking the Telephone Socket

Question

I live in the Netherlands and I have a router which I would like to hide away in my closet. Currently, it gets internet from the telephone socket seen in the image below.

I would like to place this router in my closet, near the electrical service panel, seen in the image below.

The closet includes an electrical socket, however, it does not have a socket for the internet/telephone connection. I assume that my internet/telephone cables do pass through the closet as it's the main entrance for outside connections (electricity, gas, water etc.). How can I find out which cables these are? What is a good way to hack these cables and make my own internet-socket there?

I understand that the information I have provided may not be enough to describe a detailed plan of what I should do. My question here aims to get information which can guide me in connecting the internet plug seen in the first image to whichever wires are the telephone connection in the last image.

Answer 1

For connecting the router to your phone line, you need to find the 'ISRA punt' (this is specific to the Netherlands). This is where the phone company line from outside connects to the phone wiring in your house. The cable up to the ISRA punt is owned by the phone company and you're not allowed to modify it. You are allowed to modify the wiring that comes out of the ISRA punt at the consumer end.

There have been several standard shapes for this over the years. In older houses the ISRA punt may not even be in the metering closet.

This KPN page helps you identify the ISRA punt:

Does your metering closet contain an ISRA punt?

Answer 2

I'm not sure about the Netherlands, but in the U.S., phone wiring does not necessarily have a demarcation in the same place as the rest of the utilities. The main demarcation point would be on the outside of the house in its own enclosure. From there, it goes up through the wall, into the attic (or basement), and runs to each telephone jack. Newer construction may have a junction panel inside the house somewhere like a closet for easy access.

After looking at your picture, it's possible that there would be telephone wiring in one of the conduits in the picture. You would need to find a way to access the wiring in each one visually, of course.

Tracing the wiring in the attic or basement is the best way to know for sure.
