AudioCodes Enabling Technology Products
AC48304 Voice over Packet Processor for Client Applications
¥ Low per-channel cost and power
¥ Independent channel operation
¥ Toll quality voice compression
¥ Robust bandwidth-saving fax relay
¥ Small footprint
¥ Proprietary evaluation & development tools
www.datasheet4u.com
The AC48304 is an ideal voice processing engine for a variety of Voice over
IP, Voice over DSL and other voice over packet client applications. The AC48304
VoP processor is a four ports voice over packet processor that combines toll
quality low bit rate voice compression, T.38 compliant fax relay and other
voice band processing functions. Field-proven, feature-rich software enables
the rapid development and fast time-to-market of the complete solution. The
AC48304 is based on VoIPerfect architecture, AudioCodes’ underlying, best-
of-breed, core media gateway technology for all of its products.
Deliver Feature-Rich Solution
The AC48304 voice over packet processor combines four channels of toll
quality low bit rate voice compression, with an adaptive G.168-2002 compliant
echo canceller, and complete voice band processing functions in a single
device. Field-proven G3 Fax Relay, compliant with the T.38 ASN.1 standard,
is a major enhancement to the AC48304 offering. Other advanced features
include dynamic packet size programming, high quality DTMF/MF R1/MF
R2/Call Progress Tones, detection and generation of user defined tones and
Caller ID, silence suppression, and automatic voice/fax/data discriminator.
Fast Integration with Software Stacks
The AC48304 is supported by the VoicePacketizer TM software stack which
enables the processor to create a VoIP-compliant media stream as part of a
client entity. The VoicePacketizer is an ANSI-C software stack that supports
the RTP/RTCP protocol. The software stack also provides a simple API for
initialization and configuration of the AC48304 and for run-time call control.
Software Upgrades
The complete functionality of the AC48304 is implemented in the internal
DSP software. The software image is downloaded into the AC48304 by the
host processor prior to start of operation. This allows the addition of new
features in future product releases without any system hardware modifications.
Benefit from Extensive Experience
AudioCodes is one of the world’s leading providers of DSP solutions since
1996. During this period, the company successfully passed numerous
interoperability tests while maintaining high levels of performance. AudioCodes’
commitment to innovation yields consistently high-quality voice processing
products that are feature-rich and field-proven. AudioCodes has deployed
close to 10 million VoP ports to date.
