Cisco 890 Series Integrated Services Routers Data Sheet
Cisco® 890 Series Integrated Services Routers (ISRs) combine Internet access, comprehensive security, and wireless services in a single high-performance device that is easy to deploy and manage. They are well suited for deployment as customer premises equipment (CPE) in enterprise small branch offices and in service provider managed-service environments.
Cisco 890 Series ISRs deliver integrated security and threat defense, protecting networks from both known and new Internet vulnerabilities and attacks. These powerful, fixed-configuration routers provide secure broadband, Metro Ethernet, and wireless LAN (WLAN) connectivity. Service providers offering managed Ethernet WAN services can deploy them in customer locations as CPE. You get centralized and remote management capabilities through web-based tools and Cisco IOS® Software for full visibility and control of network configurations at the remote site.
The 890 routers simplify the deployment of Ethernet WAN services, with end-to-end operations, administration, and maintenance (OA&M), service-level agreement (SLA) monitoring and verification, and configuration management.
