I have a new ADSL install pending in a house with multiple jackpoints. However, I just want 1 line directly to my router as I have no need for the other points or a phone. I've traced the jackpoint in question to the ETP

The blue and white wires on the right are terminated at the router jackpoint. Is it just a case of using a couple of gel joiners on those two and the white and brown wires from the black cable? Which one to which one?
Cheers
