3.30 Audio levels specifications
The audio of the Telit GE863-PRO
3
modules 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 Telit GE863-PRO
3
modules have 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 GE863-PRO
