5.6.13 System Module - Digital Signal Processing
The System Module also employs a State-of-the-Art audio Digital Signal Processing (DSP).
Audio DSP is used to improve audio clarity, provide consistent audio leveling and enhanced tone
generation and decoding for more flexible and reliable control functions.
The DSP provides line cancellation used during 4-wire mode to prevent unwanted signaling on
the line, notch filtering during voted applications and line audio level processing employing
compression and threshold settings.
