Police system converges voice and data

British Transport Police is completing a major network renewal as part of its overarching IT infrastructure overhaul. The police force is preparing to switch on a converged IP network that can carry roughly four times the traffic at the same cost as before.

The main achievement was to replace its ageing metropolitan and local area networks, in anticipation of a move to new headquarters in Camden in November. In their place the force has rolled out a converged voice and data network from Global Crossing.

From October, British Transport Police will migrate its wide area network off fixed 64-bit ISDN lines onto Global Crossing's broadband DSL network.

It will also replace its 2mbps metropolitan leased lines with Global Crossing's faster Metro Ethernet Access service, which uses the firm's 25 city rings and the facilities of its 50 partners.

British Transport Police will use Fast (10/100Mbit) and Gigabit Ethernet for its local area networking connections.

One challenge in designing the network was to incorporate the police force's two major "enhanced communications lines" that go to two different telephone exchanges from its seven main London offices. "We cannot afford to lose communications. It is an expensive thing to do but we do not have a choice," said Andrew Watson, head of technology at British Transport Police.

"The project to replace leased lines countrywide is due for completion in November. I cannot think of another organisation that is doing what we are doing. We had to undertake the commercial and technical negotiations within the same financial year. We have a professional procurement department that has aided us."

Watson said he is already seeing cost savings from the work that has been completed. "We are seeing more savings on our telecoms costs, and getting two to four times the bandwidth for the same costs," he said.
