Massive amounts of HEC errors

Weaver:
Burakkucat will be the man to ask. Wonder if this is the same for TT Retail, TT Business and TT’s Wholesale arrangements with ISPs? Three cases possible to consider. AA user TT Wholesale a lot so I wonder if this affects them.

jon_:
Slight development... I've managed to get telnet access, and the modems support SNR tweaks..

Once DLM has put you on a 15dB SNR target with interleaving, is there much else it can do? If I force it to connect at a lower SNR is it likely to start doing really nasty stuff like rate limiting the connection?

ejs:
Is it 20CN ADSL1 or 21CN ADSL2+?

jon_:
21CN ADSL 2+...

Hum? I haven't seen any sign of a new DLM process.  :-\

Still bumbling on, much as always, in The Cattery --
