	rj-45 jack installation
I am new to network cabling and am installing a system in our new offices. When checking the system, we found that pins 3 and 5 cross over in the jack. Is this correct or have we got some defective jacks. Also, What is the purpose of this if it is correct? Thank You

Dear Bryce, If they are cross overed INSIDE the jack (before the part where they go in parallel), it's fine. It's a technique for compensating exessive cross-talk between pairs. This is how I understood your question. Please send me more info if that's not what you were looking for. Sincerely, Dmitri Abaimov, RCDD
