Digium Launches Echo Cancellation Cards

HUNTSVILLE, Ala. and CHICAGO -- Digium Inc., the creator of open source telephony today announced the availability of two new echo cancellation cards, the TE406P and the TE411P for Asterisk, the industry’s first and most widely used open source PBX. Asterisk offers a strategic, highly cost-effective approach to voice and data transport over TDM, switched, and Ethernet architectures.

The TE406P (for use with a 5.0-volt PCI slot) and the TE411P (for use with a 3.3-volt PCI slot) support both E1 and T1 environments and are selectable on a per-card or per-port basis. The TE406P and the TE411P will support ultimate density and performance with echo cancellation for four full T1 (96 channels) or E1 (124 channels) and improves voice quality in situations where software echo cancellation is not sufficient, is not done at the CO, or where CPU utilization must be minimized. The cards are designed to perform in the most difficult of environments while providing capacity/length trade-off by supporting 16ms of echo cancellation over 128 channels, 32ms over 64 channels, or 64ms over 32 channels.

“The combination of Digium hardware and Asterisk software enable numerous combinations and configurations,” said Mark Spencer, president of Digium and the creator of Asterisk. “Our new cards will scale better while improving the system’s density and voice clarity.”
