Intelligent ADSL Rate Adaptation
The upstream and downstream data rates are
d
ynamically allocated by the AT-ARW256E to
minimize noise and maximize service reliability.
For each session, the ADSL connection speed is
automatically reconfigured to achieve maximum
data throughput (within the limits imposed by
the service provider).
Flash Software Update
The AT-ARW256E can be upgraded simply
and quickly by loading new firmware into flash
m
emory using the simple, browser-based
application. New enhancements can be loaded
into the unit in a matter of minutes.
