Wolverine DDW-225能够经济高效地远距离（最大15 km）搭建以太网络，且数据传输速率可达到5.7 Mbit/s。SHDSL技术让原有的电缆线路可得到再次利用，从而可节省大笔资金。根据线缆特性，传输距离最远可达15 km（9.3 mi）。DDW-225支持WeOS操作系统，能够方便地配置复杂的网络功能。对于简单应用，DDW-225甚至无需配置，因而非常适合快速安装。

DDW-225专为重工业应用而设计，配备坚固的铝合金外壳。宽范围的输入电源和I/O报警触点，使其在工业应用环境中便于安装，易于监控。瞬态阻断单元（TBU）被认为是防止由雷击或者高压设备导致的有害噪声尖峰的最有效方式。

只使用工业级部件，使得DDW-225的MTBF（平均无故障时间）达到70万小时，并且可确保长使用寿命。设备外壳无风扇或散热孔设计，可实现宽工作温度范围–40到+70°C（–40到+158°F）。DDW-225已通过威斯特摩内部和外部测试机构的检测，满足大多数EMC、隔离、振动和冲击标准，并达到重工业环境和铁路轨旁应用的最高水平。

威斯特摩开发的WeOS，能够提供跨平台、面向未来的解决方案。WeOS可提供该类产品中独有的IP安全功能，例如可利用基于内部端口的防火墙功能来创建多端口DMZ。使用加密VPN可以远程安全访问网络。

使用威斯特摩FRNT协议或OSPF可以组建DDW-225环网来实现弹性。DDW-225可用于企业网络。如需WeOS功能的更多信息，请参见WeOS参数表。

The Wolverine DDW-225 can cost-effectively set up Ethernet networks over long distances (up to 15 km) with data transmission rates up to 5.7 Mbit/s. SHDSL technology allows old cable lines to be reused, which can save a lot of money. Depending on the cable characteristics, the transmission distance can be up to 15 km (9.3 mi). The DDW-225 supports the WeOS operating system, making it easy to configure complex network functions. For simple applications, the DDW-225 does not even need to be configured, making it ideal for quick installation.

The DDW-225 is designed for heavy industrial applications with a rugged aluminum housing. A wide range of input power supplies and I/O alarm contacts make it easy to install and monitor in industrial applications. Transient blocking units (TBU) are considered the most effective way to prevent harmful noise spikes caused by lightning strikes or high-voltage equipment.

Using only industrial-grade components, the DDW-225 has an MTBF (mean time to failure) of 700,000 hours and ensures a long service life. The housing is designed without fans or heat dissipation holes to enable a wide operating temperature range - 40 to +70°C (-40 to +158°F). The DDW-225 has been tested by Westmore's internal and external testing facilities to meet most EMC, isolation, vibration and shock standards and to the highest levels for heavy industrial environments and railside applications.

WeOS, developed by Westmore, provides a cross-platform, future-proof solution. WeOS provides IP security features unique to this category, such as the creation of a multi-port DMZ using internal port-based firewall capabilities. Secure remote access to the network with an encrypted VPN.

Using the Westmore FRNT protocol or OSPF, DDW-225 ring networks can be constructed to achieve resilience. The DDW-225 can be used in enterprise networks. For more information on WeOS features, see the WeOS Parameter Table.
