Below is a link to my folders which show the Stats I have collected over the past few days, could someone who knows abit about these stats have a look for me and let me know if they think that there is a problem with my line?
It is possibly the effect of increased crosstalk over the months.
You also have quite a high interleaving depth & there are quite regular peaks in FEC errors & errored seconds, suggeting quite a bit of 'interference'
It also appears that you have quite a long line from the cabinet.
Do you know roughly how long the line is?
I see that your modem's firmware was updated in the early hours of this morning.
My line length is around 1000m or so in length & my sync speeds have gone from around 30 Mbps to around 20Mbps since January (again, probably due to crosstalk according to a number of visiting engineers).
I have seen a marginal improvement since my modem was updated in October.
You may also see a slight improvement too, due to revised band plans etc.
FWIW, I'll very soon be releasing an update to HG612 Modem Stats
which should deal with some of the 'glitches' shown in your ongoing graphs (gaps here & there).
