CR00015525 ADSL, Core - With this software version, AR440S routers with a hardware revision of
M1-2 (or later) will support ADSL2 and ADSL2+ connections. You can see
the hardware revision of a router by entering the command show system
and checking the “Rev” column for the “Base” board.
When running this software version, AR440S routers with rev M1-2:
■ have the following new options for the command set adsl standard:
adsl2 connect only to devices offering ADSL2
adsl2plus connect only to devices offering ADSL2+
auto2plus connect at ADSL2+ if this is offered by the other end
device (CO), or otherwise automatically fall back to
what is offered
■ have a default ADSL standard setting of auto2plus
■ behave as they currently do for other ADSL standard settings
When running this software version, existing AR440S routers with a
hardware revision of M1-1 or earlier:
■ do not have the new options adsl2, adsl2plus, or auto2plus for the
command set adsl standard
■ still use the existing default ADSL standard setting of auto, which allows
automatic fallback connection for ADSL standards only.
