The Cisco® 5900 Series Embedded Services Routers (ESRs) are optimized for mobile and embedded networks that require IP routing and services. The flexible, compact form factor of the Cisco 5900 ESRs, complemented by Cisco IOS® Software and Cisco Mobile Ready Net capabilities, provide highly secure data, voice, and video communications to stationary and mobile network nodes across wired and wireless links. The Cisco 5915 ESR is a high-performance, ruggedized router designed for use in harsh environments—offering reliable operation in extreme temperatures and under shock and vibration conditions typical for mobile applications in rugged terrain. With onboard hardware encryption, the Cisco 5915 ESR offloads encryption processing from the routing engine to provide highly secure yet scalable video, voice, and data services for mobile and embedded outdoor networks. The router offers high performance, five Fast Ethernet interfaces (two routed and three switched), and a rich Cisco IOS Software feature set, providing investment protection for customers deploying bandwidth-intensive applications in mobile or embedded networks in heavy industrial, public safety, transportation, defense, and energy markets.
