Odd Interleaving.
I have been trying an old DG834GT for two weeks and have noticed that there are two interleaving sets of data.

I switched back yesterday from from forcing the modem on ADSL instead of what it is set to now ADSL2+ the interleaving was 32 D / 2 up
Hopefully in a few days the interleaving will come back down again.
On this modem I have noticed before you get 'G.dmt framing' and 'ADSL2 framing' .
Odd, How can this be ?.   :hmm:

Weaver:
Mad illiterate UI. It's usually illegal for hackers old or young to be able to string a few words together to make some plain English sensible text, in my experience. That's why I took charge of tech documentation personally most of the time.

But that doesn't really answer your question- you will need me to explain the cause of the madness?

aesmith:
What strikes me is that at 52dB loss, 5.8dB noise margin, you should be running a whole lot faster than 3meg.

ejs:
Presumably it's a 3Mb banded WBC (21CN) profile, which explains the high INP value (which is the reason for the high interleaving depth and FEC ratio).

Weaver:
Agree with aesmith.
