11.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
Voice Activity Detection/Silence Suppression/Comfort Noise
Voice Activity Detection (VAD) detects whether or not speech is present. This lets the BM2022
reduce the bandwidth that a call uses by not transmitting silent packets when you are not
speaking.
When using VAD, the BM2022 generates comfort noise when the other party is not speaking. The
comfort noise lets you know that the line is still connected as total silence could easily be mistaken
for a lost connection.
Echo Cancellation
G.168 is an ITU-T standard for eliminating the echo caused by the sound of your voice
reverberating in the telephone receiver while you talk.
