Software Universal image and Cisco Services Ready Engine (SRE)
module enable you to decouple the deployment of hardware and software, providing a
flexible technology foundation that can quickly adapt to evolving network
requirements. Overall, the Cisco 3900 Series offers exceptional total cost of
ownership (TCO) savings and network agility through the intelligent integration of
market-leading security, unified communications, wireless, and application services.
