Digium Wildcard TE407P

Digium Quad Span with Echo Cancellation Card for Asterisk™
Supports Both E1/T1 in one single card.

The TE407P offers an on-board DSP-based echo cancellation module. It supports E1, T1, and J1 environments and is selectable on a per-card or per-port basis.

The VPM450M echo cancellation module provides a certified carrier-grade algorithm that has been labeled a benchmark for echo cancellation. This new module improves upon our older VPM400M and TE411P/TE406P products. With the VPM400M, 16ms or 128taps of echo cancellation were possible across 128 channels. The new VPM450M enables users to eliminate echo tails up to 128ms or 1024 taps 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.

The TE407P supports a 5.0v PCI slot only. If you are unsure about the PCI slots on your motherboard, please click the following link on Digium site.
