engineer has been this morning. Not faults on the line or noise !. they have done a profile reset in the cab to 80/20 but he said i would have to wait 10 days for line training if this does not fix a swap around in the cab would be needed. am i right in thinking that the attainable rate should not of moved from 88/30 its now currently 46/19 and this is this issue not the sync speed
