The green and orange pairs are transposed between 568A and 568B.  As
long as
both ends are wired to the same scheme you shouldn't have any problems.

The problems usually arise when you buy some more CAT5 outlets (either
because you ran loads of CAT5 but could only afford to terminate some of
it,
or you had to install some more because you didn't believe a UKHA when
everyone told you to double what you thought was way too much ;) and
they
are marked/coded differently.

Mark McCall experienced this (and the not installing enough CAT5 bit :-P)
-
we punched down some new Clipsal stuff and it didn't work.  This is
where a
LAN tester such as http://www.automatedhome.co.uk/article.php3?story_id=753
becomes invaluable to quickly identify things like this.
