IEEE 802.11g wireless ADSL bridge/router w/ 4 Ethernet ports & 1 USB port
The AT-ARW256E is the perfect solution for
the small office or branch office that wants
to use high speed, ‘always on’ ADSL services
to access the Internet or other corporate
locations. Combining a wireless access point,
ADSL modem, IP router, 4-port 10/100TX
switch and Stateful Inspection Firewall into one
affordable unit, the AT-ARW256E provides the
ideal solution for bandwidth-hungry end-users
and ADSL service providers who need security.
The AT-ARW256E is easily installed over an
existing analog line, supporting standard POTS
operation together with state-of-the-art ADSL
services. Applications include data intensive
office use, fast web download, video-ondemand,
video streaming and telecommuting
via Virtual Private Network (VPN). VPN
operation is supported using IPSec, PPTP and
L2TP pass-through.
Because ADSL offers an ‘always on’ connection,
users are actually more at risk using this service
than with conventional modem dial-up. To
counter this threat, the AT-ARW256E is
equipped with a powerful Stateful Inspection
Firewall that protects against malicious attacks
from the Internet – giving peace of mind
security for the home and office LAN. In
addition, a built-in ‘Intrusion Detection System’
protects against a wide range of Denial of
Service attacks. Network Address Translation
(NAT) also ‘hides’ all LAN users behind one
public IP address, protecting the LAN from
external hackers. Single PPTP or multiple IPSec
and L2TP sessions are supported using the
AT-ARW256E’s sophisticated pass-through
capability; standard NAT limitations are no
longer a barrier for the power user.
The AT-ARW256E is ADSL2 and ADSL2+
compliant, supporting up to 12Mbps and
24Mbps downstream data rates respectively.
Using industry-standard Discrete Multi-Tone
(DMT) technology, the AT-ARW256E supports
network speeds up to 8Mbps downstream and
up to 1Mbps upstream. Alternatively, G.lite is
supported for applications where minimum cost
and tool-free installation is required. Close
partnering with Digital Subscriber Line Access
Multiplexer (DSLAM) vendors ensures the
highest levels of interoperability for service
providers, with extensive ADSL testing being
carried out. Built-in support for PPP over
Ethernet (PPPoE) and PPP over ATM (PPPoA)
provides full compatibility with existing ISP dialup
systems. Bridged Ethernet and IP over ATM
complete the range of flexible and robust
network connectivity options. Superior
rate/reach performance ensures that service
providers and users alike enjoy maximum data
throughput at maximum line-lengths from the
exchange.
Installation takes a matter of minutes using the
simple, browser-based configuration interface.
Standard cabling is used to connect to the
Ethernet LAN and ADSL. All cables, including
USB, are supplied with the product. All TCP/IP
Operating Systems are supported, including
Windows, Linux and Mac. An integral DHCP
server provides automatic IP address
assignment to all PCs on the LAN to minimize
network administration. Both static and
dynamic IP address assignment are supported
on the ADSL interface, so that all connection
modes are supported.
