I'd be most grateful for any opinions or advice on this anomaly:-
We performed a horrible DSL speed test this morning.
Strangely it almost looks as if DLM or another regulator is running the line at quite horrible near-sync conditions after the fault is triggered by cause(s) unknown.http://www.dslreports.com/speedtest/12671865
We then did a 5 minute power-reset of the modem followed by another speed test and, quite astonishingly, we have a low, but acceptable increased upload and download, speed on this line. http://www.dslreports.com/speedtest/12672119
Meanwhile a local bonded set of ADSL services continue unaltered at a sync speed of 2.68, 2.21 and 1.99 Mbps download.
This problem has been ongoing for almost a year so has just been escalated to email@example.com
Does anybody know what ADSL data is available to this team so we might perhaps suggest they monitor a particular parameter ?
We also see that the bRAS checker in the public domain produces much lower figures than on normal ADSL or VDSL services.
I wonder if there could have been an error in the configuration profile ?
