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.

Cisco IOS Software Licensing and Packaging

Cisco IOS Universal Image

A single Cisco IOS Universal image encompassing all functions is delivered with the platform. Advanced
features can be enabled simply by activating a software license on the Universal image. Technology
packages and feature licenses, enabled through right-to-use licenses, simplify software delivery and
decrease the operational costs of deploying new features.

Three major technology licenses are available on the Cisco 900 Series; these licenses can be activated
through the Cisco software activation process identified at https://www.cisco.com/go/sa. The following
licenses are available:

●

IP Base: This technology package is the default

●

Application Experience (APP): This license includes data and application performance features

●

Security (SEC) or Security with No Payload Encryption (SEC-NPE): This license includes features for
securing network infrastructure
