Digium VPMOCT032LF 32 Channel Hardware Echo Cancellation Module

Product Information

Specification

Description:

The Thirty-two (32) Channel Hardware Echo Cancellation Module is designed for use with Hybrid, AEX/TDM2400, and TDM400/800 cards. This module, offering 128ms (1024 taps) of echo cancellation across all channels, is an improvement over the older VPM100M module, which only provided 32ms of echo cancellation. The VPMOCT032LF delivers the same toll-quality, G.168 compliant echo cancellation as Digium's HPEC software-based commercial echo canceller. Unlike software-based solutions, the VPMOCT032LF is immune to system CPU spikes. It is compatible with Digium's twenty-four port analog card (TDM2400P), the eight-port analog card (TDM800P), and will also be used with future Digium interface cards.
