Some 5yrs ago I moved the telephone socket. Didn’t have the correct cable so just extended the 2 wires that were physically connected in the socket. That cable was buried under concrete so is not accessible. Phone works fine but now thinking of getting fast broadband via the telephone rather than the virgin cable that I presently have. What wires does the broadband use? Will the fact that only 2 of the wires were extended mean that the broadband won’t work?
