I just wanted to ask whether a modem which supports ADSL2/2+ (G.DMT.bis/G.DMT.bisplus) modulation better than a modem which only supports ADSL1 (G.DMT) modulation on MTNL's line?I had read somewhere that ADSL2+ modems can establish a connection even when the line is noisy.Is ADSL2/2+ better off than ADSL1 when it comes to the question of frequent disconnections?
