Maximizing the Value of Ethernet Technology
in Multimedia Train Backbone

  • Behind the advanced technology, sophisticated instrumentation, and rich audio/visual connectivity of a modern train control system, there is a solid and dependable network. As train control systems have advanced, the requirements of train control networks have also kept pace. Networks need to deliver a high level of bandwidth and availability in order to support CCTV, PA, alarm, and control systems all on the same network, while still maintaining a reasonable total cost of ownership that does not overwhelm the operator with maintenance or operational burdens.

    Railway operators have achieved the network performance and flexibility they need by combining Ethernet Train Backbones (ETB) with Ethernet Consist Networks (ECN). The complete train control network must be able to manage traffic within consists and also between consists while avoiding IP address conflicts, and also deliver data from the on-board network to trackside control centers. What's more, the network must be able to perform in an unstable moving platform, which also physically changes when train consists are rearranged.

    Moxa Rail Solutions

  • Layer 3 Advanced Network Management:

    The TN-5816 and 5818 support layer 3 switching functionality, which simplifies the integration of multiple subnets. Each carriage consist can now be mass-configured with identical device IP without causing IP address conflicts. The layer 3 switches divide each consist into a subnet and allow data and information to flow between them.

  • Layer 3 Advanced Network Management
  • Future-Proof Gigabit Transmission

    It takes a lot of bandwidth to deliver the advanced technology, rich audio, and video data used in an onboard CCTV system; availability needs to be high as well to maintain uptime. Moxa’s
    EN 50155 managed Ethernet switches create future-proof Turbo Ring networks that can deliver large amounts of video data. These solutions meet increasing demands, have backup links that quickly respond to link failures, and also improve surveillance functionality without imposing additional operation costs.

  • Future-proof gigabit transmission
  • Efficient Dynamic Ring Coupling Technology

    In addition to network availability, high reliability and efficiency are also key factors in onboard CCTV systems. Moxa’s EN 50155 managed Ethernet switches feature Dynamic Ring Coupling technology that excels in inter-consist network redundancy. When train carriages are reordered, Dynamic Ring Coupling detects and automatically reconfigures the network. This technology reduces configuration time and potential human error, so the system is both highly reliable and efficient to operate day-to-day.
    Note: Dynamic Ring Coupling is available for custom projects

  • Efficient dynamic ring coupling technology
  • 802.11n Auto Inter-Carriage Connections

    For carriages that are connected wirelessly, Moxa’s Auto Carriage Connection (ACC) will automatically form 802.11n wireless bridges between adjacent wireless APs. ACC is available in the 802.11n AWK-RCC series, which supplies up to 300 Mbps of bandwidth to comfortably support media-on demand services.
