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.
Was going to say, despite my loathing of waste, I'd probably chunk of bag of unlabelled jacks. Hell, you'll waste a few fucking up anyway.
I'm usually the type to just deal with the annoyance and use them up to prevent tossing them. Probably a minor enough annoyance.
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.
Thankfully I don't need to worry about that for stuff later than ~2010.
Yeah but it still explains the โwhy?โ
Useless for 10/100. If you want gig you need the 4th pair.
So, useless for home internet, but useful if you want to use your PC VM on your laptop
They made 2 variations so it could coexist with older Telco wiring.
To prevent crosstalk inside the cable and between cables in the same location, among other reasons.
