It is means that whenever the SNR margin below par is mostly due to the phone line problem? Cause mine doesn't have any noise when pickup the phone.

Current SNR margin is between 8 - 15 only. Therefore i been disconnect almost 10 mins frequently. Effort to call Streamyx help is dissappointing coz they always divert us to tmnet. Shouldn't they inform the tmnet to come and check our line since they already know most of the SNR margin low is due to phone line rather than DSLAM.
