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
• Independent Power Down mode for each group of 2 channels for power management
• Conforms to ITU-T G.165 and G.168 Recommendations
• Field proven, high quality performance
• Compatible to ST-BUS and GCI interface at 2Mb/s serial PCM
• PCM coding, µ/A-Law ITU-T G.711 or sign magnitude
• Per channel Fax/Modem G.164 2100Hz or G.165 2100Hz phase reversal Tone Disable
• Per channel echo canceller parameters control
• Transparent data transfer and mute
• Non-Linear processor with high quality subjective performance
• Protection against narrow band signal divergence
• Offset nulling of all PCM channels
• 10 MHz or 20 MHz master clock operation
• 3.3 Volts operation with 5-Volt tolerant inputs
• No external memory required
• Non-multiplexed microprocessor interface
• IEEE-1149.1 (JTAG) Test Access Port
Applications
• Voice over IP network gateways
• Voice over ATM, Frame Relay
• T1/E1/J1 multichannel echo cancellation
• Wireless base stations
• Echo Canceller pools
• DCME, satellite and multiplexer systems
