    @ Essebe

    ^^ Great explanatory image ! ^^

    Is SNR Margin and Attenuation dependant on modem's modulation type ?
    I'm using DNA-A211-I and I've set the modulations to G.dmt and ADSL2+.
    Is it ok.

    Sonmetime I am getting the SNR Margin of 6 dB and line Attenuation of 28 dB. (both the values are of downstream.)
    So is it the time to call BSNL linemen ?
