This product has been replaced by:
Digium - TE436BF Four Span Digital T1/E1/J1/PRI PCI 3.3/5.0V Card and Hardware Echo Cancellation (1TE436BF)
The TE412P 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 TE412P is a bundling of our leading TE410P product and our new VPMOCT128 Octasic DSP-based echo cancellation module. The VPMOCT128 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 VPMOCT128 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. Digium has designed the TE412P to be fully compatible with existing software applications and it is fully integrated with the Asterisk Open Source PBX/IVR platform. Also, the open source driver supports an API interface for custom application development. With the combination of Digium hardware and Asterisk software, numerous combinations of telephony configurations are possible. From the traditional PBX to VoIP Gateways, Digium solutions are paving the way for a new generation of worldwide communications. The TE412P supports industry standard telephony and data protocols, including Primary Rate ISDN (both N. American and Standard Euro) protocol families for voice, PPP, Cisco, HDLC, and Frame Relay data modes. Both line-side and trunk-side interfaces are supported, also included are advanced call features. The TE412P is for use only with a 3.3 volt PCI slot.
