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
combined with Eurotech's embedded Linux wireless communication
controller, the DuraMAR router enables prime contractors and
systems integrators to achieve mobile communications-on-the-move
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 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 to IP65, EN50155, EN61373, as well as
radiated and conducted EMI/EMC levels and immunity to EN50121.
One 10/100Mbit Ethernet port is brought out through a sealed
locking automotive grade connector. Wireless devices covering
technologies such as GPRS/EDGE/UMTS/HSDPA, Wi-Fi 802.11 a/b/g
and/or CDMA2000 EV-DO revision A may be integrated inside the
DuraMAR 2150 router.
A dedicated internal 3-band GPRS/GSM modem allows remote access
to the DuraMAR 2150 for diagnostics, status monitoring and
configuration, as well as providing alarms using SNMP protocol.
This independent wireless interface enables remote access to
HW modules of the system such as the embedded PC and router
wireless interfaces as well as the CISCO router components.
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 x USB port for
maintenance of the controller are located on the front panel
under a sealed service panel.
The system is conductively cooled. The anodised chassis eliminates
all moving parts and incorporates 4 x M4 jam nuts for simple installation.
