It is immune to wire reversal if you reverse the
wires of the same color at both ends. Pairs
are color coded, and need to stay paired.
Some pairs are twisted tighter than others, so
you can interchange pairs and usually have a
working cable.
Many devices, NIC's, hubs, etc. can automatically
correct for a miswired pair, if the wires of one
color are only reversed at one end.

Subject: EIA/TIA 568B Color code
Hi
In EIA/TIA 568B the pins to color code arrangements are as follows:
Pin Code
1 Orange/White
2 Orange
3 Green/White
4 Blue
5 Blue/White
6 Green
7 Brown/White
8 Brown
Is it true that this arrangement is made according to each wire electrical
properties and if mixed the cable will not work. I mean by mixing is that by
mistake inserting the Orange color in Pin 1 at both ends of the cable,
instead of the Orange/White in a straight-through cable.
I tried that mistake and the cable worked. Just not sure if some type of
applications are sensitive to this arrangement.
By the way, there are some other standards for making cables. What the major
differences between them and and which one is the recommended.
Many thanks to every contributor to this group. Given the fast life and the
time stress an IT pro is experiencing, spending a time to help a stranger is
considered a very nobel work.
Regards
Adiah
