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. The Cisco 3800 series supports 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), while still supporting the existing portfolio of modular interfaces. This ensures continuing 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 dramatically reduces the cost and complexity of managing remote networks.Cisco Unified Communications brings voice, video, data, and mobility to help employees communicate effectively no matter where they work or what devices they use. The solution streamlines business processes, helps employees reach the right resource the first time, and increases profitability.Cisco Integrated Service Router Unified Communications Bundles combine award-winning hardware and software components from Cisco to provide a unified communications solution expressly for small and medium-sized businesses (SMBs) and enterprise branch offices.
