Octasic introduced a new series of echo cancellation and voice quality enhancement (VQE) modules for telecom equipment manufacturers. The OCT9600 series is a family of voice processor modules offering a range of densities from 256 to 4032 channels. These modules are powered by Octasic’s OCT6100 echo cancellation chips, which use a unique echo cancellation algorithm to improve voice quality. Advanced features of the modules include ITU G.169 automatic level control, automatic noise reduction, integrated debugging and monitoring, extensive in-band signaling tone detection, audio conferencing, announcement storage and playback, and in-path tandem free operation (TFO) capabilities.

- Octasic was founded in 1998 and has been an outsourced design house for ATM and IP voice-over-packet solutions for major telecommunications vendors, such as Ericsson, Alcatel, Nortel Networks, NEC and Fujitsu. The company is now developing its own line of ASICs for key VoP functions: packetization, aggregation and mediation; compression; and echo cancellation. Octasic offers specialized processors performing each one of those individual functions.
