The Polycom® V²IU series enables reduced costs for your enterprise, by simplifying deployment, management and security of converged video, voice and data networks.

NAT(Network Address Translation) and Firewall traversal issues are resolved by performing video and voice NAT at the public/private IP address boundary. This eliminates security risks posed by other traversal methods that 'tunnel' or obscure video and voice traffic at the existing perimeter.

The Polycom® V²IU 4300T employs a stateful packet inspection firewall in combination with an application layer gateway, providing comprehensive application-aware security. This approach enables the Polycom® V²IU 4300T to dynamically provision and close TCP and UDP ports as needed by video and voice endpoints.

Optimizing the quality of your video and voice calls is easy, as the Polycom® V²IU 4300T routes video and voice traffic via the shortest path possible to minimize jitter, latency, and packet loss. At the same time, bandwidth not in use by video or voice is made available, so that data traffic can burst up to its full line rate, maximizing WAN bandwidth. This also maximizes access link utilization while optimizing video and voice quality, using prioritization, traffic shaping, call admission control, and diffserv marking/policing.

For small and medium office connectivity, the Polycom® V²IU 4300T provides an Ethernet WAN port and q software-selectable, integrated T1 CSU/DSU or E1 interface. This allows you to use it either as your WAN access router, or install it behind an existing WAN access router.
