2.14 Audio levels specifications
The audio of the
UC864-E/G is organized into two main paths:
•
internal path (called also MT)
•
external path (called also HF)
These two paths are meant respectively for handset and headset/hands-free use. The
UC864-E/G has
a built in echo canceller and a noise suppressor, tuned separately for the two audio paths; for the
internal path the echo canceller parameters are suited to cancel the echo generated by a handset,
while for the external audio path they are suited for a hands-free use.
For more information on the audio refer to the
UC864 Hardware User Guide.
