Overview of the new standards
G.dmt = G.992.1 = ADSL
G.dmt.bis = G.992.3 = ADSL2 better performance loop diagnostics improved initialization & fast start-up power management …
G.adslplus = G.992.5 = ADSL2+ More downstream bandwidth
(spectrum 2.2 MHz) up to 24 Mbps / at least 16 Mbps
READSL2 = Annex L G.992.3 Reach Extended ADSL2
G.dmt = G.992.1 = current ADSL
G.dmt.bis = G.992.3 = ADSL2
G.adslplus = on G.992.3 = ADSL2+
