Overview
The Synway FXM series are analog voice boards newly developed for Asterisk system. They can
work with Asterisk system and allow various configurations by using different modules to provide
all features and functionalities of common voice boards. What’s more, they have the enhanced
capability in echo cancellation (128ms for time delay estimation on each channel). As a link
between the board hardware and Asterisk, they are only used to set up the Asterisk platform, but
not applicable to secondary development.
Figure 1-1 is a typical application model with FXM.
