Cisco 2901 ISR routers are designed to enable the next phase of branch-office evolution,
providing rich media collaboration and virtualization to the branch while maximizing operational
cost savings…
Additionally, a new Cisco IOS Software Universal image and Services Ready Engine module enable
you to decouple the deployment of hardware and software, providing a flexible technology
foundation which can quickly adapt to evolving network requirements.
Overall, Cisco 2901 Integrated Services Router (ISR) delivers highly secure data, voice, video, and
application services for small and middle-sized offices. Now, let’s share the diagram for Cisco
2901/K9 router.
