Keith,
This is a bit off subject but what is the correct mapping of all the
pins from a BT socket to an RJ45 ? I found something on the web ages
ago which says...
BT 1 (unused) -> RJ45 6
BT 2 (B wire) -> RJ45 4
BT 3 (Bell) -> RJ45 1
BT 4 (Earth) -> RJ45 2
BT 5 (A wire) -> RJ45 5
BT 6 (unused) -> RJ45 3
The bell wire in this schema goes to pin 1 - which is different to
your comment (and thus 99% likely to be wrong).
I actually crimped my phones with RJ45's before I found this - so my
phones conform to no standard known to man or beast. I'd like to redo
them to fit the definitive standard (whatever that is).
Cheers,
Steve
