Hello
I checked many specifications for ADSL routers and almost each missed some information about ADSL G.992.1 support. So specification shows router supports ADSL G.992.1 and no more info.
Does it mean such routers support only ADSL G.992.1 Annex A or they support both Annex A and Annex B by default?
Thanks
