SN ratio thats correct. And I see i made another typo. Voice margin is noise margin. I wanted to see what the maximum quality could be. The quality is ok here considering I have voice over IP with a ISDN/annex B SN-marge 8,5 Line Attenuation18,5 / 27,5 So if anyone know a tool

Hi, I have a question. On an adsl connection it is important to have a ns margin / voice margin higher then 6. Is there a tool somewere that can calculate the max margin possible?
