New Digium T1 Cards with Octasic Echo Cancellation Now Shipping!
Digium has recently released (4) new products featuring onboard DSP echo cancellation from Octasic.
The TE412P Quad T1 for 3.3V PCI, the TE407P Quad T1 for 5.0V PCI, the TE212P Dual T1 for 3.3V PCI and the TE207 Dual T1 for 5.0V PCI.
These new models offer an on-board DSP-based echo cancelation module. They support E1, T1, and J1 environments and are selectable on a per-card or per-port basis.
Echo cancellation is provided by Digium’s 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 our 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 these products to be fully compatible with existing software applications and they are 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.
These products support 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 for business VoIP.
