The Fast Ethernet Train Backbone Node (ETBN) is used when two or more trains need to be connected together. The Train Backbone Node has been specially designed to meet the requirements specified by IEC 61375 for the Ethernet Train Backbone (ETB) network.

The Train Backbone Node has four 100BASE-TX switched ports for Train Backbone Network implementation, and one 100BASE-TX port to be connected to the Consist Network.

The two pairs of Backbone ports are equipped with bypass functions.

One or more ETBNs can be used together with an active/passive redundant configuration to obtain the maximum level of protection.

IEC 61375 Train inauguration procedure is fully supported, as well as ETBN control interface for TRDP devices. Routing and address translation rules for multiple consist networks interconnections are automatically defined during train inauguration. Other interfaces (SNMP, REST) are also available, in order to provide a wider range of potential implementations. The TTCMP provides automatic device configuration and continuous monitoring, giving the customer a way to reduce commissioning and maintenance costs.

Designed to operate in harsh environmental conditions typical of rolling-stock applications, and fully EN 50155 compliant, the ETBN provides the highest level of reliability and robustness required by the railway industry.
