Manufacturer’s Description

The Cisco 1841 router is designed for secure data connectivity and provides significant additional value compared to prior generations of Cisco 1700 Series routers by offering more than a fivefold performance increase, integrated hardware-based encryption enabled by an optional Cisco IOS Software security image, and a dramatic increase in interface card slot performance and density while maintaining support for more than 30 existing WAN interface cards (WICs) and multiflex trunk cards (voice/WICs [VWICs]-for data only on the Cisco 1841 router) of the Cisco 1700 Series.The Cisco 1841 modular architecture has been specifically designed to meet requirements of small-to-medium-sized businesses and small enterprise branch offices as well as service provider-managed applications for concurrent services at wire-speed performance.
