CS6420 General Description

Most modern speakerphones use half-duplex operation, which switches transmission between the far-end talker and the speakerphone user. This is done because the acoustic coupling between the speaker and microphone is much higher in speakerphones than in handsets where the coupling is mechanically sup.
