Configuration Guide For Trunk Side IP PBX Applications

Companies with existing IP-based WAN links for inter-office voice and data

communications can use the 4300T as a traffic shaper to meet the stringent jitter,

latency and packet loss requirements for toll quality voice. The 4300T is deployed at

the edge of the WAN in both headquarters and branch office locations, as shown

below.

The 4300T performs WAN/LAN IP routing and traffic management functions in this

application. In particular, it provides prioritization to ensure voice packets are not

delayed or dropped while allowing data traffic to use all remaining bandwidth.
