I am planning to install a RJ45 flush plate close to the telephone flush plate. What I am trying to do is to place the ADSL modem in a room rather than in the kitchen area. To do so, I am planning to get a cable with RJ11 in one end, and RJ45 in the other, so it can go from the central filter (adsl modem outlet) to the RJ45 outlet, and then at the end of the RJ45 (in bedroom), RJ45 -> RJ11 -> Modem. How do I go abouts wiring RJ11 to RJ45 plug, in terms of the pin outs etc. Cheers.
