The DuraNET 1XRTT is a rugged cellular modem companion node designed to provide reliable wireless backhaul connectivity for the Cisco 3200-based DuraMAR router. Supporting Verizon's 3G Wireless National Network over an 800MHz 1xRTT band, the unit adheres to CDMA2000 1X authentication standards and provides data throughput rates up to 153.6 kbps.
An ideal solution for on-the-move network connectivity in information-level railroad and military applications, the DuraNET 1XRTT features a simple cable and power management scheme with serial data and power signals being carried through a single MIL-C-38999 connector capable of being powered and routed directly by a PowerWithSerial (PWS) port on a DuraMAR router. Front bushing holes and rear protruding pins enable tool-less installation/removal when mounted "piggyback" on a DuraMAR router using an optional dagger pin mounting ring or if mounted standalone from the router using the front/rear dagger pin mounting bracket set.
To enhance reliability and robustness, the 1XRTT node incorporates no moving parts, operates over a wide temperature range of -40ºC to +70ºC and uses a compact, hardened aluminum extrusion. Since the modem is physically external to the DuraMAR chassis, heat dissipation is further improved. This distributed architecture also serve to potentially strengthen signal integrity (by reducing analog antenna cable length), while providing a simplified upgrade path for future communications technologies, since the DuraMAR router need not be modified/replaced during perpetual radio upgrades.
