Description
The MT9300 Voice Echo Canceller implements a cost effective solution for telephony voice-band echo cancellation conforming to ITU-T G.168 requirements. The MT9300 architecture contains 16 groups of two echo cancellers (ECA and ECB) which can be configured to provide two channels of 64 milliseconds or one channel of 128 milliseconds echo cancellation. This provides 32 channels of 64 milliseconds to 16 channels of 128 milliseconds echo cancellation or any combination of the two configurations. The MT9300 supports ITU-T G.165 and G.164 tone disable requirements.
Features
• Independent multiple channels echo cancellation; from 32 channels of 64ms to 16 channels of 128ms with the ability to mix channels at 128ms or 64ms in any combination
