Hi,
is there a standard or 'recognised' order for the colours when attaching connectors to cat5e cable and corresponding wallboxes?

cheers MG
 
"does it matter?"
You better believe it matters...
Obviously you have not worked with cabling that has to meet standards, Do you even have the proper tools? There is more to it then just getting the wires in the correct order.
 
"does it matter?"

yes at two levels:

For the electronics, at 10 or 100 megabits, it is vital that pins 1&2 be a pair and pins 3&6 be a pair. At gigabit, the other wires must be correct as well.

For humans, any wire one cannot identify is junk. I have tons of specialized RS-232 cables that are unmarked and therefore useless. (My mantra when we converted to ethernet was "at least it is not RS-232") With Cat 5 one can check the ends and know what use the cable has. Any cable you make with wrong ends will just confuse some poor human who is left trying to support the mess. It could be you.

I tried to remain child-like, all I acheived was childish.
