"At Adaptive Digital, we recognized long ago the impact that voice quality has on telephone users. Whether speaking with family, friends, or business colleagues, the telephone network must provide a conduit for clear, comfortable conversation," said Scott Kurtz, Adaptive Digital^s vice president. "We are both proud and pleased to learn that our attention to voice quality has yielded us an echo canceller that exceeds the requirements of AT&T, the company whose network historically defined the term ^carrier class."

The importance of voice quality cannot be overstated in the Voice over Packet (VoP) market; the subjective quality of voice signals perceived by listeners is the most important differentiator for most equipment providers. The network that provides enhanced call quality will establish permanence by securing loyalty in its customer base. As one of the key enabling technologies for VoP, echo cancellation is fundamental to that success. Implementation of echo cancellation in digital and cellular networks increases Quality of Service (QOS), which in turn increases revenue. AT&T^s "carrier grade " rating of Adaptive Digital^s echo canceller assures the manufacturers of Voice over Packet product clarity provided traditionally by the circuit-switched network.
