Yeah, why is this the case? I have to refer to a diagram whenever I punch down a jack. Always forget where the green goes.

    I sing a little ditty in my head:

    Orange-stripe, orange, green-strip, blue,

    Blue stripe, green, brown-stripe, brown.

    If it's the "other" scheme? Fuck me, to the diagrams I go.

    EDIT: Realized you're talking about jacks. Aren't they all clearly labelled these days, with both schemes?

    Yeah, the good ones are labeled, but I have a bag of unknown origin that don't have it on the side. I should probably just get a new bag.

    Blue in the middle is pair 1. Orange around that is pair 2. Green on the left, brown to the right.

    CC-B-AA-B-DD.

    Pair A is for telephone back when Ethernet was wired to a punch down block. Pair B and C are for data. Swap b and c on one end for crossover.

    The fourth pair is basically useless.
