Introduction
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. The DDW-225 Ethernet Extender is the ideal solution for
extending your Ethernet network over copper cables where in the past the only option would have been fibre. At shorter range the transfer rate will be as fast as 5.7 Mbit/s in both directions. Transmission distances up to 15 km are possible, however at a reduced data rate. The SHDSL transmission technology makes the DDW-225 perfect for the re-use of existing copper cable installations from older communications networks. The Ethernet Extender supports two SHDSL interfaces and can therefore be used to create a daisy chain or ring network. The units will auto negotiate the transmission speed but can also be forced to choose a slower (more reliable) or faster (less reliable) data rate. With its built in four-port Ethernet switch the DDW-225 is the only unit required to build a complete Ethernet solution. The DDW-225 uses the Westermo WeOS operating system already employed in our range of RedFox industrial Routing Switches. Using WeOS provides the DDW-225 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.
