OK guys the modem is here (fast shipping from broadbandbuyer) and forgive me if mentioned models but is for educational purposes
All i have to say about this small modem is
W O W
Snr is set by default from isp at 9db & dslam is broadcom
Have an asus n55u and un-tweaked is locking about 9.500 kbps - trend/ralink
Tweaked (they added an snr tweak value via UI) 12.500 db but the snr staying at 9 db
A draytek locking at 10.500 but not tweaks possible - ADI
The 7700n will lock around 11.500
via telnet 0x32 or 50 about 13.000 ... can see the snr is set at 6db
& with 65550 value will lock around 14.000 kbps ... can see the snr locked at 3db but getting disconnections
How ever very pleased with this small modem and with 36 db attenuator the speed is more than expected even from kitz forum calculations

Note changing modems for testing and updating the 7700 firmware plus the snr tweaks the line seems gone slower so my guess after few days when settle again may give little more speed

My question is how to set high priority path 1 at dsl ... or if i set Link Power State high .... will make any difference for the disconnections with snr 3db?
Thanks
