Introduction

The ToughNet TN-5508A series M12 managed Ethernet switches are designed for railway applications, such as rolling stock, and wayside installations. The TN series switches use M12 and other circular connectors to ensure tight, robust connections, and guarantee reliable operation against environmental disturbances, such as vibration and shock. The TN-5508A series Ethernet switches provide 8 Fast Ethernet M12 ports. In addition, the -40 to 75°C operating temperature and IP54-rated waterproof enclosure allow deployment in harsh environments. Moreover, the TN-5500A series is compliant with the mandatory sections of EN 50155, covering operating temperature, power input voltage, surge, ESD and vibration, making the switches suitable for a variety of industrial applications.

White Paper: Optimized Ethernet Redundancy for Inter-Consist Networks Download

Network redundancy is a critical factor in ensuring passenger safety and journey reliability in onboard railway communications for both intra-consist and inter-consist Ethernet networks. In addition, railway operators are looking for ways to more efficiently allocate resources and serve passenger demands. For example, metropolitan rail services may want to run trains with fewer consists during off-peak hours but longer trains with more consists during rush hour. Railway operators can also serve multiple markets and conserve track assets by connecting multiple consists with different destinations into one train if they will travel along the same route for at least part of the journey. 

This white paper describes how Dynamic Ring Coupling helps railway operators provide seamless onboard Ethernet redundancy with both rapid recovery times and automatic Ethernet switch configuration even when consists are rearranged mid-journey.
