Polycom V2IU 4300T Series User manual

Connect any way you want with an all-in-one networking
and security solution for your enterprise edge
The Polycom V2IU 4300T helps reduce costs by simplifying the deployment, management and security of
converged video, voice and data networks. To begin with, it helps resolve NAT/firewall traversal issues by
performing video and voice NAT at the public/private IP address boundary, which eliminates the security risks
of other traversal methods that tunnel or “obscure” video and voice traffic from existing perimeter security.
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 full line rate,
maximizing WAN bandwidth. It 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
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.
The Polycom V2IU 4300T series enables you to access the power of Polycom unified collaborative
communications solutions.
With the greatest breadth and depth of integrated video, voice, and Web solutions, only Polycom delivers
the ultimate communications experience. Our market-leading conferencing and collaboration technologies,
