| AudioCodes Enabling Technology Products AC48304 Voice over Packet Processor for Client Applications 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. 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.168-2000 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. 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. Fast Integration with Software Stacks Low per-channel cost and power Independent channel operation Toll quality voice compression Robust bandwidth-saving fax relay Software Upgrades Small footprint Proprietary evaluation & development tools 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.
