Configuring the V2IU 4350

•Controls the data transfer rate of far-end WAN TCP devices to limit WAN link congestion.

•Supports network-based QoS applications by setting the TOS bits for all VoIP packets sent to the WAN and the LAN. TOS bits are used so that VoIP packets can be prioritized in the network by DiffServ enabled routers. The TOS bit value used by the 4350 is to “minimize delay and maximize throughput”, or 0xb8 hexadecimal. This value is set for all VoIP packets processed by the 4350 and overwrites any specific TOS bit configuration set by VoIP endpoints.

•Ensures that bandwidth allocated to new voice and video calls does not adversely affect the quality of existing active calls (Call Admission Control or CAC).

The 4350 combines sophisticated traffic management mechanisms including classification, prioritization, queuing, rate limiting and CAC to ensure high quality voice and video calls. Fortunately the system manages this complexity for you and configuring traffic management is very straightforward:

1.Enable traffic shaping.

2.Specify the upstream and downstream bandwidth of your WAN link.

3.Enable CAC.

Please follow the steps below to configure and enable traffic management.

Enable Traffic Shaping

1.From the Configuration Menu, select Traffic Shaper.

2.Select the Enable traffic shaper checkbox.
