Re: T568A and T568B - WAS KAT5, CAT5 + Clipsal

["Keith Doxey" <ukha@xxxxxxx>]

Hi Phil,

You could also have looked at
http://www.diyha.co.uk/electronics/rj45.html

T568A and T568B are ELECTRICALLY the same in that the pin connections
are identical, the only difference is the Orange and Green pair
colours are transposed. Any equipment (including KAT5) will happily
work on either A or B wiring.

Problems arise when, as you have discovered, you have patch panels
and sockets that are marked with opposing colour schemes. If you just
follow the Pin Numbering it will work fine.

I've been following the T568B pionouts my wiring, I'm thinking that
maybe the Clipsal is marked for T568A, therefore it never would have
worked.  Well its somewhere to start anyway :-)  Here's a link to the
site I used  http://stresscow.org/~jfuller/rj45/rj45.htm
