Ethernet over cat5e telephone system in apartment.

My apartment is wired with cat5e for the telephone wires, one of which is already set up with an RJ45 connection (I'm assuming someone had Uverse in here previously). The others are all RJ11(with two connections available).

So the question is two-fold, can I use an adapter to make the two RJ11s on an outpost an RJ45 connection (rather than deal with converting it to an RJ45 connection)? The second part is can I then use these for wired networking as they're all connected in the AT&T telephone box (although I don't want to destroy their equipment either)?

I'd be connecting my main router to a switch, so I'm hoping that this should be an easy question to someone who's familiar with these boxes. Let me know if you need any additional details.

There is a good chance your RJ11 connections are actualy split from Cat5 cable, so you might be lucky.

Find where all these wires originate from. In many cases, all the wires are connected in parallel (as to provide for phone network throughout premises), on a panel like this

If you terminate these wires with RJ45 connectors at this end, and RJ45 wallplates at the other, you can have pure Cat5 network.
To a point the wire is all the same. You can make rj11-rj45 adapter cables if you can live with only 2 pair...ie limited to 100m. Still telephone wires are almost always all connected together at one location. You will have to remove all the wires from that splice point and somehow connect them to a switch. The best location for this switch is in that box which may not be a option if this is not in a area you do not have exclusive control over. If it is someplace in a closet in your apartment you could pull the wires from the splice blocks put rj45 ends on them and plug them in a switch. When you are ready to leave you would cut the ends and put them back into the splice block.

I am not real sure I would attempt it if you are not sure you can get it back to standard after.

Thanks Alabalcho, that module is pretty similar to the one that's in my apartment. As that's not my forte of expertise, I was hoping that they were connected through that module, so I appreciate your insight on that. I was hoping there's be an adapter for the dual jacks, but guess it's probably simpler to just rewire an R45 wall plate on there. I'll post an update once I get the chance to do so.
