What are the primary differences between the Cisco CVA120 Series and the Cisco uBR900 Series?
A. The Cisco CVA120 Series provides one Ethernet port and one USB port for data and two telephony ports. Data capability is limited to IP routing and Cisco Easy IP, and the Cisco CVA120 is primarily positioned as a flexible cable voice over IP (VoIP) platform. On the other hand, the Cisco uBR900 Series products support a rich set of Cisco IOS Software features such as Cisco IOS Firewall and IPSec hardware-acceleration on some models. The Cisco uBR905 and uBR924 feature a four-port Ethernet hub, while the uBR914 supports a serial interface.
