Is RJ11 pin order like RJ45 where the order is always the same (e.g. Brown is always on the left, when looking from the bottom), or should they be mirrored - one side with red on the green's right, and the other with the green on the red's right?
According to the layouts I saw on the internet it seems that they should be like RJ45 - the same. But when checking an RJ11 cable that I have, it's mirrored - one's left-to-right is the other's right-to-left.
So which one is it?
1Its preference, because the information is passed over wires in a symmetrical pattern, unlike RJ45, where the wires that are paired are in order. typically they are not mirrored. But you only need two wires to make a pair, and if your pairs are symmetrical about the interface it doesn't matter which is tip and which is ring. – Alice – 2018-08-22T20:10:10.903
@Dylan Thanks. So I guess the official answer would be like RJ45, but people won't be careful about it because it doesn't matter, hence my RJ11 cable. – ispiro – 2018-08-22T20:13:44.560
