Annex A or B related information (NOTE from DSL-N66U f/w 1.0.7.3)
My question to ASUS:
1.
Possible bug in syslog:
Administration -> DSL Settings -> Annex Mode = Annex B/J/M (I selected B on setup)
and yet
System Log -> DSL Log says, "Annex Mode" = "ANNEX_A"
Maybe this is related to the following that I found on the web: "For example, VDSL2 Annex B Plan B (aka Bandplan G.998) used by BT Openreach for its Profile 17a service is compatible with G993.2 Annex A for the Americas (an Annex with only one bandplan)."
Asus Reply:
For question 1, yes, they are compatible. So you can choose Annex B/J/M but running with Annex A. Our driver will choose the proper one.
However, we suggest to choose the correct mode, for your case is Annex A/I/J/L/M.
My interpretation:
1. When I selected Annex B in the quick setup for UK openreach, the DSL-N66U knew that openreach uses VDSL2 Annex B Plan B (aka Bandplan G.998), and also that this is compatible with G993.2 Annex A.
It therefore chooses to configure itself as G993.2 Annex A. Thus G993.2 Annex A is what I see on the logs.
Asus suggest I change the configuration to select Annex A/I/J/L/M directly.
