Description
DDW-226 is an Ethernet extender with integrated switch and support for legacy serial
connections. It uses the Westermo WeOS operating system that provides the DDW-
226 with all the advanced switching and routing functionality supported by the DDW-
226. These functions include VLAN support, Layer 2/3 switching, Static Routing, Firewall
functions, IGMP Snooping, VPN support.
A further enhancement the DDW-226 provides is a set of advanced diagnostic functions
that allow the SHDSL line to be dynamically monitored allowing alarms to be config-
ured to pre-warn of any performance issues. This monitoring data can be accessed in a
number of ways; it can be read at any time through the Web Interface, Command Line
Interface or via SNMP.
A key function of the DDW-226 is its ability to be used to create redundant ring net-
works over the SHDSL links, using both the Westermo FRNT protocol, but also RSTP.
