威斯特摩以太网扩展器技术基于SHDSL，能够重新利用许多类型的原有铜电缆，从而在安装新系统时显著节约成本。Wolverine DDW-142能够创建超长距离（最大15 km（9.3 mi））的高效以太网网络，一根简单的双绞线电缆的数据传输速率可高达15.3 Mbit/s。通过“胶合”双绞线，该传输速率可翻倍到30.4 Mbit/s。集成交换机能够连接2个以太网设备，一个RS-232端口能够将一个遗留设备纳入到IP网络中。

WeOS（威斯特摩操作系统）开发用于提供跨平台、面向未来的解决方案。WeOS可为该类产品提供独有的安全功能，允许DDW-142利用威斯特摩FRNT协议或者工业标准STP/RSTP成为弹性多介质环网的一部分。WeOS开发用于提供工业网络解决方案，具有卓越的串行连接性能 – 从模拟旧AT调制解调器，转换Modbus RTU到TCP，直到封装串行数据到IP数据包中。

DDW-142拥有难以置信的灵活性和易用性。无需进行任何类型的配置，即可创建一个点对点或者多点网络。然而，如果有更复杂的解决方案需要一些网络配置，则可以使用网页界面轻松完成。另外还可提供CLI界面，以便网络专业人员可以方便地快速控制设备。一旦系统配置完成，则简单的解决方案还可用于维护工程师 – USB备份和恢复意味着可以从USB闪存盘自动下载存储的配置。

DDW-142通常用于铁路、道路或者故障可能导致巨大成本的公共事业等应用中。所有威斯特摩产品设计时都以高MTBF为目标，以提高运行可靠性以及提供长使用寿命。甚至具有SHDSL诊断和管理功能，能够指示线路退化从而允许计划维护。由于产品专为这些应用设计，威斯特摩还确保产品已经过测试，以确保设备可在极端温度、EMC和振动环境中运行，并仍然提供可靠的通信。

Westmore Ethernet extender technology is based on SHDSL and enables the reuse of many types of legacy copper cables, resulting in significant cost savings when installing new systems. The Wolverine DDW-142 is capable of creating highly efficient Ethernet networks over extremely long distances (up to 15 km (9.3 mi)), with data transfer rates up to 15.3 Mbit/s on a simple twisted-pair cable. By "gluing" twisted pair, this transfer rate can be doubled to 30.4 Mbit/s. An integrated switch can connect two Ethernet devices, and an RS-232 port can incorporate a legacy device into an IP network.

WeOS (Westmore Operating System) was developed to provide cross-platform, future-proof solutions. WeOS provides unique security features for this class of products, allowing DDW-142 to be part of an elastic multi-media ring network using the Westmore FRNT protocol or the industry standard STP/RSTP. WeOS was developed to deliver industrial networking solutions with superior serial connection performance - from emulating old AT modems, converting Modbus RTU to TCP, to encapsulating serial data into IP packets.

The DDW-142 offers incredible flexibility and ease of use. Create a point-to-point or multipoint network without any type of configuration. However, if there is a more complex solution that requires some network configuration, it can be easily done using a web interface. A CLI interface is also available so that network professionals can easily and quickly control devices. Once the system is configured, a simple solution is also available for maintenance engineers - USB backup and recovery means that the stored configuration can be automatically downloaded from a USB flash drive.

DDW-142 is typically used in applications such as railways, roads, or utilities where failures can result in significant costs. All Westmore products are designed with high MTBF in mind to improve operational reliability and provide long service life. There are even SHDSL diagnostics and management capabilities that indicate line degradation to allow scheduled maintenance. Because the products are designed for these applications, Westmore also ensures that the products have been tested to ensure that the equipment can operate in extreme temperature, EMC and vibration environments and still provide reliable communication.
