Powered by Octasic’s certified carrier-grade algorithms, the OCT6100 performs high quality Echo Cancellation (EC) and Voice Quality Enhancement (VQE) functions.

The OCT6100 was designed for a broad range of applications; it supports densities from 16 to 672 channels on a single chip and offers extensive features such as Acoustic Echo Cancellation (AEC), signaling tone detection, audio conferencing, background music solutions and more. This feature-rich device is offered in a 16mm x 16mm footprint—the smallest in the industry.

Used independently or combined with other Octasic voice processing solutions, the OCT6100 can significantly increase density in voice gateways while offloading DSPs to maximize their use for other value-added features. The OCT6100 requires minimum integration, greatly simplifies design, and accelerates time-to-market.
