This is probably one for Paul but if anyone else knows that will be fine.
I am needing to make up a phone patch cord from a US (RJ11?) phone cable but with a British Telecom plug on the other end (computer modem conectivity). I seem to recall that the UK uses the outer two pins for line 1 as opposed to the centre two. I am not certain about the polarity though on a UK telephone connector.
I see that unlike 8 pin cat 5 computer plugs, each end of a telephone lead is wired as a mirror image of the other.
Thanks - just about to reach for my UK raincoat!
