Certificate

Module description

The Cisco 800 and 1900 Series Integrated Services Routers are routers that provide collaborative business solutions for data communication to small businesses and enterprise teleworkers. They offer Metro Ethernet and multiple DSL technologies to provide business continuity. The routers provide the performance required for concurrent services, including firewall, intrusion prevention, content filtering, and encryption for VPNs for optimizing voice and video applications.

Security level exceptions
