| The
DDW-120 Ethernet Extender is the ideal solution for
extending your Ethernet network over copper cables where
in the past the only option would have been fiber. At
shorter ranges the data rate will be as high as 5.7
Mbit/s in both directions. The technology used suggests
transmission distances of up to 10 km at lower data
rates, depending on the quality of the cables. In
practical applications however much greater distances
have been achieved. The SHDSL transmission technology
makes the DDW-120 perfect for the re-use of existing
copper cable installations from older communications
networks. It is transparent for multicast addressing,
VLAN packets, allows VPN pass-through for IPSec and can
be used with protocols like MODBUS/TCP and Profinet IO.
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. DDW-120 can be used in
point-to-point applications or as start or termination
unit together with the DDW-220/222/225 in daisy-chain
applications. |

| The
DDW-225 / 226 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 / 226 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 / 226 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 / 226 is its ability to be used to create
redundant ring networks over the SHDSL links, using both
the Westermo FRNT protocol, but also RSTP. |
