The Cisco 3800 Series includes the Cisco 3825 and Cisco 3845 Series Routers. These routers integrate a comprehensive set of security features such as firewall, IPSec and Secure Sockets Layer (SSL) VPN, intrusion prevention system (IPS), and voice call processing with advanced wired and wireless services for rapid deployment of new applications that include application layer functions, intelligent network services, and converged communications. The 

Cisco 3800 Series is available in three optional configurations:

​• AC power

• AC power with integrated inline power support

• DC power

In addition, two new models, C3825-NOVPN and C3845-NOVPN, offer all the features supported by the Cisco 3825 and Cisco 3845 Series, with the exception of VPN payload encryption and secure voice features. These two new models provide a limited set of security features, such as firewall, and IPS, compared to the Cisco 3825 and Cisco 3845 Series Routers.
