Digium Echo Cancellation Module VPMOCT128M
Digium VPMOCT128M H/W Echo Cancellation Module
Digium VPMOCT128M H/W Echo Cancellation Module for Quad Span. VPMOCT128 provides a certified carrier-grade algorithm that has been labeled a benchmark for echo cancellation. The new VPMOCT128 enables users to eliminate echo tails up to 128 milliseconds / 1024 taps (codeks' utlization of the frequency of 8 KHz) across all 128 channels in E1 mode or 96 channels in T1/J1 modes. Further, this module takes advantage of the Octasic Voice Quality Enhancement to provide superior sound quality on all calls. This new module improves upon our older VPM400M/VPM450M products With the VPM400M, 16 milliseconds / 128 taps (codeks' utlization of the frequency of 8 KHz) of echo cancellation were possible across 128 channels.
