Converged Network Appliance  
Benefits  
Connect any way you want with an all-in-one networking  
and security solution for your enterprise edge  
Simplifies deployment issues  
• All-in-one network and security solution  
for converged voice, video, data networks  
• Offers either T1 or Ethernet WAN access  
router  
• Integrated four-port managed Ethernet  
switch with VLAN support  
The Polycom V2IU 4350 converged network appliance 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.  
• Embedded LAN side gatekeeper support-  
ing up to 15 registrants  
Enhances security  
The Polycom V2IU 4350 converged network appliance employs a stateful packet inspection firewall in  
combination with an application layer gateway, providing comprehensive application-aware security. This  
approach enables the Polycom V2IU 4350 converged network appliance to dynamically provision and close  
TCP and UDP ports as needed by video and voice endpoints.  
• Secures voice and video devices  
• Application layer gateway H.323 video,  
SIP, and MGCP voice that resolves  
NAT/firewall traversal issues  
• Dynamic access control list simplifies  
setup + operation  
Optimizing the quality of your video and voice calls is easy, as the Polycom V2IU 4350 converged network  
appliance 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.  
Optimizes video and voice quality  
• Routes media shortest path  
• Video and voice call admission control  
prevents congestion of priority traffic  
• Traffic management: priority queuing,  
traffic shaping and diffserv  
marking/policing  
• Supports up to 3 Mbps of traffic in any  
combination of voice, video, or data  
For small and medium office connectivity, the Polycom V2IU 4350 converged network appliance provides an  
Ethernet WAN port and software-selectable, integrated T1 CSU/DSU interface This allows you to use  
it either as your WAN access router, or install it behind an existing WAN access router.
