What is hardware echo cancellation?

Hardware echo cancellation is the most effective way to remove echo from a line. Digium's VPMADT032 hardware echo cancellation module is the most powerful to date and future Digium card models will likely be compatible with this model. Digium designed the new VPMADT032 to offers industrial strength 128ms(1024 taps) per-channel echo cancellation across all channels on the TDM card. The VPMADT032 provides toll-quality G.168 compliant echo cancellation to combat hybrid echo on the PSTN interface.

Though there are open source echo cancellation routines that are somewhat effective in eliminating this hybrid type echo, the VPMADT032 module resolves this problem in hardware, mitigating any negative effect CPU resource shortages may induce on an otherwise purely software based echo cancellation solution.

Using this card in concert with Digium's Asterisk software, standard PC hardware, and the Linux OS, you can create SME or SOHO telephony environments capable of satisfying the needs of small or medium business applications at an industry-leading price.
