2.13 Audio levels specifications
The audio of the
GE864 / GC864 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
GE864 / GC864
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 Hardware User Guide.
