Introduction
Project Introduction
When the department of transportation for one of the 50 United States decided to upgrade the traffic signal system at several intersections, one of their key requirements was setting up an IP-based networking system so they could manage and monitor the traffic signals over the Internet. In addition, they wanted to integrate an IP CCTV surveillance system over the same network. However, since it wasn’t practical to lay Ethernet cabling from intersection to intersection—because of cost constraints and since the distance between intersections was too long—they were faced with the problem of how to set up the IP network.

The first solution engineers often consider in a case such as this is fiber cabling. However, in this case fiber also wasn’t a viable option due to the difficulties associated with deploying new fiber cable either above or below ground. Consequently, they decided to re-use the existing 2-wire telephone-grade copper wires already installed and stretching from 1 to 2 km between intersections. The challenge was how to ensure that the network would be fast enough and reliable enough to handle network packets for both traffic signals and IP cameras.
