somewhat strange your cross.. I am accoustumed to use the 568A/568B normalized cross, which is:

1-white-green
2-green
3-white-orange
4-blue
5-white-blue
6-orange
7-white-maroon
8-maroon

the other side:
1-white-orange
2-orange
3-white-green
4-blue
5-white-blue
6-green
7-white-maroon
8-maroon

as you can see, the green/orange pairs are the switched ones. Also, you *must* use the corresponding white of each pair - no mix/max whites please (Alcatel cables have no coloured strips), otherwise the crosstalking can produce a lot of collisions..

change the cable accordingly and try again.
