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。
