RS 208-1786 RJ45 to BT

Part, erm, lost count, lets say 8, of operation run cable from lounge to study.   Wanted to plug the BT socket and CAT6 into the same face plate/back box but could only find 4 port RJ45 face plates.  Enter RS 208-1786 - RJ45 to BT conversion.


Pins 4 and 5 on the RJ45 port are the equivalent BT pins 5 and 2 (the ones you want).
