Is that a lot of crosstalk then?
I think I've lost a bit of speed to crosstalk, but I don't think much as I was one of the early ones onto the cabinet when it went live and its never been a lot faster than this. Pre G.INP I was getting mid 30s DS sync, with the best I've ever seen with G.INP and 3dB being about 48Mbps. I think most of the loss is purely down to the line length.
