Condition: NewDigium VPMADT032Echo Cancellation Module for TDM800 & TDM2400Hardware Echo Cancellation Digium VPMADT032 Echo Cancellation Module
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.
