UC864-E/G/WD/WDU Product Description

80281ST10034a Rev. 4 – 2009-06-24

3.14 Audio levels specifications

The audio of the UC864 family 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 family 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-E/G/WD/WDU Hardware User

Guide.
