# 3G-324M Interface overview

The 3G-324M Interface provides a flexible API for bridging 3G-324M clients into an IP network to provide access to various enhanced services applications. It allows for simple and flexible call setup with 3G-324M terminals on one side of the interface, while providing control for IPv4 or IPv6 media endpoints on the other side. Data must enter the interface in 3G-324M format.

For information about the 3G-324M Interface components, architecture, and data flow, see the Video Access Overview Manual.
