A fast question about crossover E1 cable for ISDN PRI, to connect two PBX via two pri

The card TE110P works fine also, the problem was the cable (the cable made by me and the two cables which I had buy on stores and working really bad!)
I have buy a Cat5E cable, the plugs and make cable following this perfect video-guide. I have configured the two pri as I did in the first post, I had only to reboot the pri_net machine and…works all.
