Cat6 Rj54 leads - newbie q


Hi there!

Just a quick question before I buy my purchase (last time I bought a patch instead of a crossover - best to ask, eh?)..

What is the difference between a normal Cat6 and a Cat6 RJ54 lead?

I want connect a cable from the back of my modem to a 10/100 USB adapter.. no crossover cable, right? is normal cat6 a patch cable? is this what I want?

if i get you right: you want to know the difference between twisted (crossover) and straight? i only heard about cat3/4/5 or sometimes called UTP/STP and has RJ45-telephone jacks on both sides. (is cat6 shielded?)

straight:
1 2 3 4 5 6 7 8
| | | | | | | |
1 2 3 4 5 6 7 8

crossover:
1 2 3 4 5 6 7 8
| | | | | | | |
3 6 1 4 5 2 7 8

(7/8 and 4/5 are used for thelephon and can be skipped ?not 100% sure)

if you connect a eth to another you have to use crossover. if there is a switch/hub between then use a straight cable.
some devices like switches and those routers for adsl sometimes don't care - they can "see" whats on and do it right. for the router -> adsl i thing crossover may be the right (?? not sure).
