AFAIK, there is no spec on imbalance of (each diff pair of) a port, and I will check it with my local IEEE Ethernet spec specialists. I don't know if there is a spec on the cable, but I will try to find it. I'd really like to see if the requirement from the standard has any basis in the actual real-world measurements. Neven
