You have some time to kill and a punchdown tool?

I have the colorcode written down in my PBX manual at home. I can send it 
to you tomorrow.

The basics is this....
Each wire has 1 of 5 MAJOR colors and 1 of 5 MINOR colors. So. you have 5 
majors and 5 minors. 5*5 = 25. Then each wire has an associated neighbor it 
is twisted with and has the minor/major reversed. This gives you 25 pairs. 
There is a specific order they go in and I have the order written down at 
home too. btw, the minor color is the stripe, the major is the body color. 
Some makers have the 1st wire a solid and the second the solid+stripe.

If nobody answers I'll have it tomorrow, or maybe tonight.

btw, there is an AT&T type punchdown, type 110 and type 66. The AT&T type 
is slightly interchangeable with the type 110.

AND, why do you want so many 10Mbs ports? These aren't 100Mbs. Also, CatOS 
is not IOS, so you might want to read up on it if you've never seen it.
