I'm getting a splitter installed by a Telecom technician for broadband and have few questions regarding the rest of the wiring in our house.

1) After some research it seems Cat5 or Cat5e seem to be the way to go. I understand that the data connection from the splitter will consist of a pair of copper lines. Since Cat5 have four pairs of wires I suppose only one pair will be used?

2) Secondly my modem (Linksys W200g) has a two pair (four wires) connection (is it RJ11?), so how is this interfaced with the Cat5 cable?

Yes you are correct, but depending on how the installer decides to do things a single Cat5e cable will be run from the demarc to the ADSL site only one pair is used, a filtered feed for the phone could be run on another pair in that cable.

A phone/adsl circuit is only 2wires or 1pair, only the centre pins of the RJ11 are used, the other two are not connected to anything.

Normal practice is that the installer will run the ADSL circuit to a BT socket where you ask him to place it. He will label this "ADSL", you the use a standard BT-RJ11 line cord to connect to your ADSL modem.

Thanks for clearing that up.

The technician was going to use a single pair wire, but agree to wire with Cat5e for the modem. Phone will be using existing copper wire and will not be upgraded as I will be eventually switching to Xnet Fusion or similar.

I would rather use a faceplate with four RJ45 connections like the one below rather than a single BT socket.

The reason being my modem will be connected to another computer and a HTPC in future. One of the jacks in the faceplate will be a RJ11 connected to the modem, and the rest will be RJ45 jacks connected from the modem to other computers. Is this a good way of networking a house without adding a BT socket? Or should I get a BT socket to the modem and a RJ45 jack faceplate for networking? (I couldn't find any RJ11 jacks for this particular faceplate in Cables Direct?)

RJ11/RJ12 and RJ45 jacks are all compatible with each other - they just clip in. There is no need for an RJ11/RJ12 keystone.

You are right. Clearly I don't deserve the Master Geek title!

Where can I buy this type of faceplate/jack/keystone from at a reasonable price? Master Trade?

Be aware not all RJ45 (8p8c) jacks will accept an RJ11, so physically check before you commit there are minor dimensional differences that cause issues. Yes Mastertrade/Corys can sell you parts. Beware that PDL parts are 3x the price of Keystone jacks from Dynamix or SigTech, but the quality is not that much different. So ask for the price before you commit.

Just pop into a Mastertrade or Corys and get a PDL faceplate and keystone adapters and some cat5e keystones. The small adapters are required as they clip into the faceplate so standard keystones will clip in correctly.

You can stick to RJ45's and just use one of these cables to connect to the router.

NB: the DSL line should be feed on the blue pair of the CAT5e cable.
