All

Thanks for your help, I've now done what I need to and replaced the cable with an RJ11-to -RJ11, plugged into the RJ45 socket as before. Definitely NOT plugged into the phone socket. FWIW, my faceplate looks like the right-hand image of the two posted by MrSaffron, and the RJ45 is definitely the socket on the left.

NO

The RJ45 socket is the one on the left for both the models shown at http://www.thinkbroadband.com/images/iplate/bt-adsl-...

The ADSL socket looks like it is an RJ11 socket as it is narrower than the BT phone socket. If it was an RJ45 socket it would be almost the same width as the BT phone socket.

All the routers that I own have both RJ11 and RJ45 sockets. The RJ11 socket is for ADSL. The RJ45 sockets are for 10/100/1000-Base-T Ethernet

The ADSL v1.0 faceplates had an RJ45 socket for the ADSL/broadband, I know as we had this discussion years ago and actually have plugged in an RJ45 lead to prove it.

Appearance's can be deceptive. As I sit here I am looking at a filter faceplate with a RJ45 plug in the modem socket.

Filter faceplates all accept RJ11/45 plugs. The reason is so that a network patch lead could be use to add the signal on to an already existing network, in much the same way that on some networks a telephone fitted with an RJ11 plug can pick up a phone line from a RJ45 socket.

I should have done that as well before I wrote the post!
