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.
