ZYCOO Echo Cancellation Module is designed with Zarlink ZL38065 chip for voice echo canceller,
which has the following features:
- Independent multiple channels of echo cancellation, from 32 channels of 64 ms to 16
- channels of 128 ms with the ability to mix channels at 128 ms or 64 ms in any combination
- Fully compliant to ITU-T G.165, G.168 (2000) and (2002) specifications
- Passed all AT&T voice quality tests for carrier grade echo canceller systems
- Unparalleled in-system tunability
- Sub 50 ms initial convergence times under many typical network conditions
- Fast reconvergence on echo path changes
- Patented Advanced Non-Linear Processor with high quality subjective performance
- Superior noise matching algorithm
- Per channel Fax/Modem G.164 2100 Hz or G.165 2100 Hz phase reversal Tone Disable
- Protection against narrow band signal divergence and instability in high echo environments
