General Description

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

Optional Tx Noise Guard

Programmable attenuation during double-talk

Optional 34 dB microphone preamplifier

Dual channel AGC’ed volume controls with mute

Dual integrated 80 dB IDR codecs

Speech-trained Network and Acoustic Echo Cancellers

Rx and Tx supplementary echo suppression

Configurable half-duplex training mode

Powerdown mode
