The Tesira STC-2 is a modular telephone interface card for use with Tesira SERVER and SERVER-IO devices. The STC-2 allows a Tesira system to connect directly to standard analog telephone lines. Each channel includes line-echo cancellation, noise suppression, caller ID decoding, ring detection/validation, DTMF decoding, and call progress tone decoding. When used in conjunction with Acoustic Echo Cancellation (AEC) processing, Tesira becomes a powerful, flexible, and affordable conferencing platform.
The Tesira STC-2 & Tesira STC-2 CK comply with the United States Trade Agreement Act (TAA), allowing it to be included in GSA Schedule contractors’ sales bids for the U.S. federal government.
