I have just moved into a new place and found that the wall jack has been unwired for some reason, although I am quite sure that previous tenants were using it for their modem to get internet.
Anyway I wanted to wire an RJ12 socket so that I can attach my modem but the existing wires seems to be the wrong colours to all information I can find on the subject, including the diagram that came with the socket.
Existing wiring is an 8-core with colours red, orange, green, black, white, grey.
There is also a 4-core with colours green, blue, brown, white.
I can't tell which wires were previously used. Does anyone have any ideas?
