TL;DR: WTF are pins 4,5 and 7,8 used for? Which is TX and which is RX?
So I'm working towards CCNA. Just started a study book and the first few chapters are pretty basic review stuff from college.
Anyway its said pins 1,2 on your PC (and routers, etc... for that matter) is for transmitting and 3,6 is for receiving. Opposite on a switch/hub. Alls good....
The book then goes into introducing the other two pairs for 1000Base-T but doesnt specify what 4,5 and 7,8 are used for. It doesnt mention which is for tx and which is for rx. The assumer in me wants to say 4,5 is for transmitting like 1,2 and that 7,8 are used for receiving like 3,6. this assumption is based strictly off the adjacent pins.
I cant seem to answer this question on the internet. Surely someone here knows.
SO WHAT IS IT?!
