DDW-225 Ethernet Extender
The DDW-225 is an Industrial Ethernet SHDSL extender with support for redundant rings. The redundant protocol can be used either on the SHDSL interface or on the Ethernet interface. Our unique FRNT (Fast Recovery of Network Topology) technology is the fastest protocol on the market to re-configure a network in the event of any failure of a link or hardware. DDW-225 uses the Westermo WeOS operating system that provides the unit with all the advanced switching and routing functionality supported by the RedFox. These functions include VLAN support, Layer 3 switching, Static Routing, Firewall functions, IGMP Snooping, VPN support and SNMP V3. 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 configured to pre-warn of any performance issues. This monitoring data can be accessed in a number of ways; tit 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 networks over the SHDSL links, using both the Westermo FRNT protocol, but also RSTP.
