NetModule NB3710 MultiRail

The NB3710 MultiRail enables wireless Internet access for applications like passenger WiFi & information and condition monitoring. Numerous additional communication interfaces guarantee an excellent interaction with onboard electronics.

NB3710 is an all-in-one router for railway and other fields with highest demands on the hardware. Equipped with up to four UMTS/LTE modules, the total bandwidth can be extended to the needs of the applications. Especially in passenger entertainment applications the increased total throughput gives a better user experience. The quad SIM feature and the sophisticated WAN link manager are offering load balancing, highest connection availability using multiple network providers.

Thanks to its unique port-based subnetting feature, the NB3710 is able to separate different application networks, thus avoiding interferences and guaranteeing dedicated communication paths. Quality of Service support allows prioritizing the traffic to avoid that less important tasks are blocking high priority data. The router is qualified for operating under harsh environmental conditions defined by EN 50155.

Available options include interfaces for CAN, IBIS, RS-485 and Audio Line In/Out. The device is also available with extended input voltage (72 - 110V).

The router software is based on well proven components including an embedded Linux operating system and a powerful communication protocol suite. The device is managed via web browser, command line or SNMP. Self-provisioning for new software or new configuration is possible. The device can be configured remotely by customer programs via a powerful application interface. Customer specific software extensions are possible via SDK.
