Oh dear.... perhaps not the Be DSLAM afterall.
Here we go again with the weekend wee small hours thing.
Graph 1 shows how rock steady the line normally is
Graph 2 shows the decline in upstream starting at about 05:30am
Graph 3 shows now and how the line is slowly recovering back to normal (11:45)
I dont have any record of attenuation, but it clearly shows
losses of up to 10dB of SNR on the upstream. Because my SNRm now is just shy of 16dB, this doesnt seem to have caused any ill effects at present, but its no wonder that when on adsl2+ my line couldnt handle such losses.
So it seems this intermittent problem has followed me to fttc
