The Bie Switchover Isunder Way In Sheffield

摘要

The big switchover is under way in Sheffield. The equipment is all in place and one by one, the city's junctions are switching from analogue to digital in a major programme that will see some 350 junctions under UTC control using the latest TCP/IP communications technology.rnBrent Collier of Sheffield City Council, who has overseen the deployment, explains that rather than putting all their eggs in one basket, the city has selected three main routes for their comms upgrade, fibre, DSL and wireless mesh.rnThe fibre alternative has come about as a result of SWISS, thernSheffield Wide Image Switching System. SWISS was developed with funding from the Home Office as part of Sheffield's crime and disorder reduction partnership and brings together the various providers involved in the deployment of a comprehensive CCTV system throughout the city. Central to the system is fibre optic cabling which has been installed along the entire SuperTram route and provides the UTC connections to the traffic control centre. There are 77 junctions on the Supertram route and every one of them is equipped with IP communications via the fibre netwoik.
