AT-AR441S
| Secure ADSL Router
of PICs, including BRI/PRI ISDN, high speed
E1/T1, Synchronous, and FXS VoIP.
Performance
The AT-AR441S modular router provides a
significant improvement in the performance of
Allied Telesis' modular router family.The 300MHz
CPU within the AT-AR441S ensures that large
packets are forwarded at wire-speed and that
small packets are forwarded with minimal delay.
Comprehensive Management
and Configuration
The AT-AR441S comes with a comprehensive
suite of management features and is also
compatible with SNMP based management
packages. An extensive command set is available
via the Command Line Interface (CLI), and a
browser-based Graphical User Interface (GUI) is
also provided to simplify configuration and
management of the AT-AR441S.The GUI provides
access to default set-ups in key management areas
and provides access to regional settings. Allied
Telesis' SNMP support extends to SNMPv3, which
provides the option of secure management.
