Description
DDW-225 is a part of the Wolverine family of Ethernet extenders. It uses the Westermo
WeOS operating system that provides the DDW-225 with all the advanced switching and
routing functionality supported by the DDW-225. These functions include VLAN support,
Layer 2/3 switching, Static Routing, Firewall functions, IGMP Snooping, VPN support.
A further enhancement the DDW-225 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-225 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.
