Digium VPMADT032 Thirty-two Channel Hardware Echo Cancellation Module (1VPMADT032LF)
The Digium VPMADT032
Thirty-two Channel Hardware Echo Cancellation Module (1VPMADT032LF) is a 128ms
per-channel echo cancellation module for use with Digium telephony interface
cards.
This module, which offers 128ms (1024 taps) of echo cancellation across all of
its channels, improves upon the older VPM100M echo cancellation module, that
only offered 32ms of echo cancellation. The VPMADT032 provides the same
toll-quality G.168 compliant echo cancellation found in Digium's HPEC
software-based commercial echo canceller. The VPMADT032 is immune from any
system CPU spikes that might otherwise affect a software-based solution.
