704 Appendix A Silence suppression
N0060606N0060606
Figure 221 One call on a half-duplex link without silence suppression
When silence suppression is enabled, voice packets are only sent when a speaker is talking. In a
typical voice conversation, while one speaker is talking, the other speaker is listening – a
half-duplex conversation. The following figure shows the peak bandwidth requirements for one
call on a half-duplex link with silence suppression enabled. Because the sender and receiver
alternate the use of the shared channel, the peak bandwidth requirement is equal to the full
transmission rate. Only one media path is present on the channel at one time.
