The Cisco® 900 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.
Product Overview
The Cisco 900 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 and Metro Ethernet and wireless LTE WAN connectivity. Service providers offering both
managed Ethernet and wireless LTE WAN services can deploy them in customer locations as CPE.
Centralized and remote management capabilities are available through web-based tools and Cisco IOS®
Software for full visibility and control of network configurations at the remote site.
The 900 Series ISRs 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.
The Cisco 900 Series ISRs come with a 4-port managed switch, providing LAN ports to connect multiple
devices. Figures 1 and 2 show the C921-4P and C926-4P models.
