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.
