532 Appendix B Silence suppression
NN40020-603NN40020-603
Figure 149 One call on a full-duplex link without silence suppression
When silence suppression is enabled, voice packets are only sent when a speaker is talking. When
a voice is being transmitted, it uses the full-rate transmission rate. Since the sender and receiver do
not share the same channel, the peak bandwidth requirement per channel is still equal to the full
transmission rate. The following figure shows the peak bandwidth requirements for one call on a
full-duplex link with silence suppression enabled. The spare bandwidth made available by silence
suppression is used for lower-priority data applications that can tolerate increased delay and jitter.
