GDMT vs T1.413?

[anttu]

There is rumors that changing between the modes of WAN ADSL settings mentioned in the subject has effect on ADSL connection stability, especially with Zyxel 660HW.

Do you have any experience about this?

Well... To me, T1.413 only indicates ANSI compliance (USA), while G.DMT (G.992.1) is ITU-T (Europe)... If you do find any information connecting the different standards to connection stability it would be interesting, I haven't really heard anything.
