Backbone Routers

A hierarchical structure with two levels of networks is needed to interconnect vehicles in close or open trains. Train Backbone Routers provide an Ethernet based gateway function as well as a proper redundancy between those network levels. In order to assure such "High Availability", Train Backbone Routers are designed with specific features like hardware by-pass and Active/Passive technology. Standard protocol is used for proper train inauguration procedures.
