| Overview: | D2's Low Complexity Network Echo Canceller (LCNEC) algorithm module is an ITU-T G.165 compliant network echo canceller that is designed for echo tails of 32 msec and under. |
| Ideal Performance: | Integrated with other VP Open modules and tested for concurrent real-time processing on multiple voice ports. |
| Algorithm Verification: | G.165 tests for tails of <32 msec, ERL of 6 dB: steady state residual echo test, convergence test, convergence in the presence of near end noise, halting of convergence by double-talk, halting of convergence by large continuous background noise, leak rate test, infinite return loss convergence test, and tone stability test |
