This AEC reference signal is used inside the TCC2 to steer the beam into a static status (at 315° horizontally and 90° vertically) at any time when the far-end presenter is active. The Static status is enabled when the level of the AEC reference signal exceeds a certain threshold. In order to ensure appropriate functionality of this feature, it is crucial to adjust the level of the AEC reference signal. Optimally, the level of the AEC reference signal should be adjusted in such a way that the Static status is not active when the far-end presenter is not active. In more challenging acoustic environments, this beam freeze can improve far-end echo cancellation. April 2020 Page 6
