The Integrated Ethernet Train Backbone Node (IETBN) is a perfect combination of an IEC standard Train Backbone Node implementation with a multi-port Ethernet Consist Switch. Due to this mix of backbone and consist ports, it provides an integrated and cost-sensitive solution.
Double switched backbone lines protected by a bypass relay ensure high levels of fault tolerance also in the case of a power failure. A couple of Integrated TBNs can be used together using an active/passive redundant configuration to obtain the maximum level of protection.
The Integrated ETBN can be powered from 24 Vdc to 110 Vdc nominal. Fully EN 50155 compliant, this device provides the highest level of reliability and robustness required by the railway industry.
Through the TTDP protocol, IEC Train inauguration procedure is fully supported. Routing and address translation rules (R-NAT) for multiple consist networks interconnections are automatically defined during train inauguration as well as TRDP interface. Full communication compliance with TRDP End Devices, as well as with IEC 61375-3-2 TCN communcation profile is ensured.
On the consist side, VDS Tools provide automatic device configuration and continuous monitoring giving the customer a way to reduce commissioning and maintenance costs. Eight (8) ports can be optionally equipped with PoE+.
