The number of applications used in a metro, light rail and railway environment is significant: various types of voice communications (administrative telephony, help points, emergency phones), public address, radio, SCADA, passenger information systems, access control, train supervision, ticket vending machines, turnstile systems, CCTV for surveillance, etc.

In order to offer a smooth service and maximum security to the passengers, the personnel in the control room relies on quality images, non-stop availability of control signals, and the ability to send real-time information to the various equipment via emergency announcement and signaling systems.

OTN supports this mixture of applications. They are all integrated by means of interfaces into the nodes of a redundant fiber backbone. Many interfaces, many protocols, but one simple system that ensures completely transparent communication, simple to learn, to manage, to maintain and to use. Take a look at the benefits of an OTN.
 

You can experience OTN at leading transport authorities around the world:

• Vancouver Sky Train (Canada)
• Transrapid Maglev (Shanghai, China)
• Stadtbahn Bonn (Germany)
• Tramways Lyon and Montpellier (France)
