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 16 mm 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 and greatly simplifies design and accelerates time-to-market.
