If they're accurate you are 3dB outside the limits set by BT for the 1M
service (remembering it's a logarithmic scale so for every 3dB it's
aproximately a halfing or a doubling, in your case it's the formerI'm
afraid )....

Thanks, I thought as much. I was hoping with a db of 60 that I might be
able to squeeze in but halfway through writing the original post I noitced
the upstream of 63, so thats probably where I am failing.
