Just a quick update:-
It appears that the BT supplied modem (Huawei HG612) incorrectly reports some of its statistics in its GUI, particlularly error counts.
It seems to get FEC & CRC errors mixed up with each other, & maybe neither of them are the "true" values anyway.
For now, I have started to graph exactly what is reported in the GUI, & also what is reported via the various xdslcmd info --xxxx commands from a telnet session (please see the attached 16 day graphs - apologies if it is hard to view without downloading it first).
Some of the completely blank parts of the graphs are due to the fact that I wasn't logging the relevent data at the time.
The error count appears to have reduced overall since the engineer's visit in mid-November, but the sudden bursts of various errors does occasionally cause a re-sync, which also adds / removes DS interleaving at various differing levels.
The sudden & large bursts of errors have masked out all the other less severe error counts due to the scale/size of the graphs.
The current totals for a 52 hour connection up time are:-
DS CRC 462902 (also reported as RSUnCorr via xdslcmd)
DS FEC 7197 (also reported as OHFErr via xdslcmd)
DS HEC 136565 (also reported as HEC via xdslcmd)
From looking at other users' FTTC connection stats (almost zero error counts across the board - a few hundred maximum), these error counts still loook excessive to me, indicating an ongoing & reportable D-side line "fault".
Of course, Plusnet don't see it that way as I am "currently achieving reasonable stability & my speeds exceed the estimated speeds".
Is it at all possible that something on my side of the BT modem could be causing the errors/re-transmissions, such as the router or my PC itself?
