DuraMAR 2150

Rugged Rolling Stock Mobile Access Router

Eurotech DuraMAR mobile access router provides a continuous high-availability wireless connection interfacing a moving vehicle such as a train, bus or aircraft to the fixed back-end IP-network using multiple connections that may be used simultaneously or backing-up each other. DuraMAR routers enable prime contractors and systems integrators to achieve mobile communications-on-the-move (COTM) and a wide range of new in-vehicle networking applications, from wireless Internet access to Voice over IP (VoIP), passenger Wi-Fi services to streaming video surveillance and smart vehicle diagnostics/maintenance.

The DuraMAR® 2150 is an integrated rugged Mobile IP router designed for net-centric operation in rolling stock installations such as on trains and metros. Leveraging Cisco Systems' industry standard IOS® software and 3200 series mobile access routing (MAR) technology and Eurotech embedded Linux® wireless communication controller, the DuraMAR router enables prime contractors and systems integrators to achieve mobile communications-on-the-move (COTM) and a wide range of new in-vehicle networking applications, from wireless Internet access to Voice over IP (VoIP), passenger WiFi services to streaming video surveillance and smart vehicle diagnostics/maintenance.

Ruggedization
The DuraMAR 2150 model is particularly well suited for demanding train-borne applications where system operational reliability and integrated structure are required as this rugged router is designed to meet shock, vibration, humidity, safety, and protection standards of IP65, EN50155, EN61373, as well as radiated and conducted EMI/EMC levels and immunity of EN50121. One 10/100Mbit Ethernet port is brought out through a sealed locking automotive grade connector. The Wireless terminals such as GPRS/EDGE/UMTS/HSDPA, WiFi 802.11 a/b/g and/or CDMA2000 EV-DO Rev. A may be integrated inside the DuraMAR 2150 router.

The system is conductively cooled and the anodized chassis eliminates all moving parts and incorporates 4 M4 jam nuts for simple installation.

Interfaces
An internal 3-band GPRS/GSM modem allows remote access to the DuraMAR 2150 for diagnostics, status monitoring, configuration, as well as alarms using SNMP protocol.

This independent wireless interface enables remote access to HW modules of the system such as the embedded PC, router wireless interfaces as well as the CISCO router. SNMP protocol can be used over GPRS TCP/IP data to query the DuraMAR 2150 independently of the wireless interfaces used for primary router communication.

The unit's purpose built power supply supports standard 110V DC nominal train feeder voltage inputs, spikes, and transient levels. LED status indicators for power, system and modem status, as well as SIM card holders, two console interfaces and 1 USB port for maintenance of the controller are located on the front panel under a sealed service panel.
