The integrated services routing architecture of the Cisco 3800 series is designed to embed and integrate security and voice processing with advanced wired and wireless services for rapid deployment of applications, including application layer functions, intelligent network services, and converged communications. These routers support the bandwidth requirements for multiple Fast Ethernet interfaces per slot, time-division multiplexing (TDM) interconnections, and fully integrated power distribution to modules supporting 802.3af Power over Ethernet (PoE). And at the same time they still support the existing portfolio of modular interfaces, thereby ensuring continued investment protection to accommodate network expansion or changes in technology as services and applications are deployed. By integrating the functions of multiple separate devices into a single compact unit, the Cisco 3800 series routers dramatically reduce the cost and complexity of managing remote networks.Cisco C3825-NOVPN does not support embedded VPN.
