Core Integrated Solutions are working with a Leeds City Council UTC department to roll out a fibre based city-wide network. The cable infrastructure was initially deployed into ducting provided by a district heating scheme, and a number of key locations were identified to provide connectivity across the East and South of the city. We provided ducting and chamber infrastructure, as well as network cabinets, at these key locations, and interfaced to the UTC duct networks at junctions. With an eye on future road schemes which were providing further ducted cable routes, we designed a physical fibre ring, and a multi-layer IP network, with a layer 3 10Gb diverse ring across four locations, and a number of layer 2 1Gb sub-rings providing the connectivity to the existing systems.
The network has multiple VLAN architecture, and in addition to the fundamental traffic controller connections the network also supports CCTV, AI traffic sensors, vehicle presence sensors, variable message signs, and legacy wireless connectivity. The IP architecture has been built with spare VLAN capacity to enable other systems to be brought onto the network. We are also carrying out 5.8Ghz wireless connections to edge locations on the UTC network.
At this moment we have 66 network cabinets live, or coming live, and will have fibre network connectivity to over 120 traffic controllers across the city.
