The OCT6100 Series
of voice processors
performs high quality
echo cancellation
and Voice Quality
Enhancements (VQE).
Now available in a
lower power version
as well as a lead-free
option, the OCT6100
series also offers a
full complement of
tone and compression
functions, all in a 16mm-
square footprint - the
smallest in the industry.
Superior Voice Quality
Octasic’s OCT6100 Series of voice processors sup-
ports densities from 16 to 672 channels on a single
chip. Octasic’s echo cancellation algorithm uses a
Least Squares adaptive filter with frequency aware-
ness providing superior performance for today’s
solutions. Independently or combined with other
Octasic voice solutions, the OCT6100 Series can
significantly increase density in voice gateways
while offloading DSPs in order to maximize their
use for other value added features.
Carrier-Grade Echo Cancellation
When tested by leading carrier labs, the Octasic
algorithm received very high marks and was
labeled a benchmark-algorithm for echo cancel-
lation. Certified carrier grade, the solution is now
deployed worldwide. The OCT6100 Series sets a
new standard for voice quality in networks.
Extensive Monitoring and
Debugging Features
OCT-VQM (voice quality monitoring system),
the extensive monitoring and debugging system
behind the OCT6100 Series, gives developers and
field-support engineers the ability to monitor
networks, record problems live and use Octasic
services to ensure that the best voice quality
possible is delivered to their clients. Devices are
equipped with a software debugging port,
available through an API socket, and providing
complete access to VQM solutions.
