Well I enabled telnet with http://192.168.1.1/debug.htm
Unfortunately adslctl info –stats not working just typed in telnet, I believe some some kind of access route is needed like in this example:
”
Open the telnet shell.
Issue the following commands
cd /opt/lantiq/bin press enter
Downstream
“./dsl_cpe_pipe.sh g997lsg 1 1″ – copy and paste everything between the ” ” marks – press enter
Upstream
“./dsl_cpe_pipe.sh g997lsg 0 1″ – copy and paste everything between the ” ” marks – press enter
The ATTNDR=XXXXX will be your speed in Bits divide X / 1024 / 1024 = Mbits
EG – 71797596 / 1024 / 1024 = 68.4Mbits”
And this is as far I found. It looks like bit more is needed to get full stats like on Vigor not to mention to adjust snr….
I don’t think I will have that much time to play with. Ideally I just need modem with possibly recent lantiq chipset (slightly newer than on eci modem) and easy access to telnet with possibility to view stats and adjust snr ( I do -0.8 db on downstream on mine to get full sync speed). Poor Eci modem is still on duty but God knows for how long it will be able to serve me 
Netgear dm200 its just one of my spare ones which I decide to play with until my another hobby call me in
