3 - 9

A typical 4300T installation for hosted video applications is depicted in the 

diagram below. In this scenario, the 4300Ts are used to connect all of the video 

endpoints to the Gatekeeper.  The video endpoints should be configured to 

point to the LAN address of the 4300T as the Gatekeeper and the 4300T will 

proxy RAS and call setup messages to the Gatekeeper

The 4300T is installed at the customer premises and is used as a demarcation 

point for the video service by providing the following functions: 

• WAN/LAN IP routing.
