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

The TE407P is a bundling of Digium's leading TE405P product and the new VPM450M Octasic DSP-based echo cancelation module. The VPM450M provides a certified carrier-grade algorithm that has been labeled a benchmark for echo cancelation. This new module improves upon Digium's older VPM400M and TE411P/TE406P products. With the VPM400M, 16ms or 128taps of echo cancelation 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.

Digium has designed the TE407P 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 TE407P 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 TE407P is for use only with a 5.0 volt PCI slot.

Certifications for the TE407P are pending.

The TE407P is for use only with a 5.0 volt PCI slot. The TE412P should be ordered for use with a 3.3 volt PCI slot - typically available on newer motherboards and in 64-bit PCI bus architectures.
