Description
The DDW-221 is an Industrial Ethernet SHDSL extender with support for redundancy.
The redundant protocol can be used ether on the SHDSL interface or on the built-in
Ethernet switch.
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.
SHDSL represents the best of several symmetric DSL technologies. This unit provides the
ability to reuse existing twisted copper pair with data rates from 192 kbit/s to 5.7 Mbit/s
in both directions. The DDW-221 makes it possible to communicate over 10 km
(6.2 miles) on twisted pair cable.
The DDW-221 is a bridge not router and so is simple to install. All configuration is done
using a web interface.
The DIN rail mounted DDW-221 is designed for harsh environments and can be used
in industrial and railway applications. It can be powered from two separate supplies and
handle an operating voltage range of 16 – 60 VDC.

Simple Network Management Protocol (SNMP)
The DDW-2XX supports Simple Network Management Protocol version 1 and 2c
(SNMPv1 and SNMPv2c). SNMP is an Internet standard protocol (IP) developed to
manage IP nodes (servers, workstations, routers, switches and hubs etc.) on an
Ethernet network.
SNMP enables network administrators and control engineers to manage network
performance, find and solve network problems, and plan for network growth.
The DDW-2XX MIB’s are divided into groups allowing the SNMP manager to poll
the SNMP agents for information.

Factory default
It is possible to set the unit to factory default settings by using two Ethernet cables and
connect to the unit.
To set the unit to factory default do the following:
1. Connect Ethernet cable from port 1 to port 4.
2. Connect Ethernet cable from port 2 to port 3.
3. Power up the unit.
4. Wait for the unit to start up. Control that the PWR led is flashing green.
The PWR flashing indicates that the unit will be set to factory default.
5. Remove the Ethernet cables, the unit will automatically start with factory
default settings.
Note! The Ethernet cables must be removed within 30 seconds from power up
or the unit will do a normal start up.
