AT-AR256E
| 4-Port ADSL Router
Up to 253 LAN Users Can Share
O
ne Line and One IP Address
The AT-AR256E supports up to 253 LAN-
attached users – easily enough for a small office,
while high speed ADSL services mean that they
c
an all share a single line and still have plenty of
performance. NAT allows 253 users to share
one public IP address for low-cost Internet
access.
Intelligent ADSL Rate Adaptation
The upstream and downstream data rates are
dynamically allocated by the AT-AR256E 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-AR256E can be upgraded simply and
quickly by loading new firmware into flash
memory using the simple, browser-based
application. New enhancements can be loaded
into the unit in a matter of minutes.
