i have just gone through the telnet command line guide that i downloaded from the 2800 series downloads page and have found the command to set the target SNR.

Code:

adsl codinggain 5

this should set the target SNR to 4db, but when i try this line, there is an error that says

Code:

% Valid subcommands are: [lists the possible commands]

i am using firmware version 3.3.0 with ADLS version 211801_A Annex A.

thanks for your help!

That firmware version looks like it's for the 2820 I would say.
The 2820 series is not the same as the 2800 series.

a fair answer. do you know if there is a way to do this on the 2820?

Not as far as I know, but someone else might know different.

Not possible, different chipset that doesn't support it.
