My bro now on the trial but massive FEC/CRC errors

[#1]

Plusnet Thomson TG585 stats as below. It was originally on G.992.3 Annex A but I telnetted in and forced the adsl2+ mode.
Any ideas?

At that sync rate an atten the dlm dosent allow the + to be used. if no tones above 1.1khz are used then its a adsl2 sync
Maybe try and telnet in to use adsl2 and not adsl2+. doubt it would make a diffrence thoe as the dlm overrides my dg834g v4 if i try to force a + sync.

Yeah I thought that, will put it to 2 and then check the stats....

Those high up direction counts look totally bogus to be honest. Do they appear like that immediately after a reboot or do they increment from zero?

Compute 2^32 - 1

They increment from zero.... here are the stats after I put it back to 992.3

Ah that looks better
To be honest your downstream error counts look fairly reasonable considering the sync rate, line attenuation and SNR margin.

drop in your attention as well when using 992.3

thanks for the feedback guys
