Cisco 870 Series of integrated services routers are fixed-configuration routers that support multiple types of DSL technologies, broadband cable, and Metro Ethernet connections in small offices. CISCO877W-G-A-K9 provides the performance needed to run concurrent services, including firewall, intrusion prevention, and encryption for VPNs; optional 802.11b/g for WLAN networking; and quality of service (QoS) features for optimizing voice and video applications. In addition, the Cisco Router and Security Device Manager (SDM) Web-based configuration tool simplifies setup and deployment, and centralized management capabilities give network managers visibility and control of the network configurations at the remote site.
