Can someone tell me if these settings are alright as I'm getting conflicting reports...

Are these alright? I live in the countryside so my connection is rubbish but I am on MAX DSL, which I guess would be considered ADSL2?!
Also, my target snr as set by BT is 10db. If I change the snr through the router by entering a value of 50 in the snr menu that should give me a new snr of 7db shouldn't it?
Thanks!
