2198 Westermo's DDW-120 Ethernet extender allows existing twisted pair cables to be used to establish a high-speed remote connection between two Ethernet networks. The company claims this is an easy-to-install alternative to optic-fibre or radio systems when linking remote Ethernet networks.

The device employs a transient blocking unit on each line interface to provide both over-current and over-voltage protection, allowing the line to handle indirect lightning strike transients, power induction and short circuit problems.

The DDW-120 uses twisted pair cables rather than expensive optical fibres or radio links. This plug-and-play unit covers many applications, offering data rates from 192Kbit/s to 5.7Mbit/s in both directions over distances of up to 15km (10 miles).

    Columbus, Ohio is to benefit from a US$38.1 million traffic management system to replace the one installed in the 1970s to allow the city to respond more quickly to problem areas and speed up travel throughout Columbus and even in its suburbs. The new system will wrap all signals into a single network. More data will funnel to new software in the traffic-management center, where operators can decide how to handle traffic congestion. Nearly 500 miles of fibre-optic cable will run to most traffic signals, and
