Cisco 1921/K9 C1921 Modular Router 

Cisco 1921 builds on the best-in-class. All Cisco 1900 Series Integrated Services Routers offer embedded hardware encryption acceleration, and advanced security services. In addition, the platforms support the industry's widest range of wired and wireless connectivity options such as Serial, T1/E1, xDSL, Gigabit Ethernet, and third-generation (3G) wireless.

The Cisco 1921 is designed to meet the application demands of today's branch offices with design flexibility for future applications. The Cisco 1921 provides significantly enhanced modular capabilities that offer you investment protection.

You can easily interchange modules used on the Cisco 1921 with other Cisco routers to provide maximum investment protection. Taking advantage of common interface cards across a network greatly reduces the complexity of managing inventory requirements, implementing large network rollouts, and maintaining configurations across a variety of branch-office sizes.
