AC482xx
The highly featured, low cost and low power consumption AC482xx enables the rapid development of medium density gateways, access devices and routing/switching equipment, Residential Gateways and Integrated Access Devices (IAD). With AudioCodes’ field-proven, feature-rich software, the route to the complete solution is fast and smooth. The AC482xx can serve as a low cost direct replacement for the AC481xx. The AC482xx is based on VoIPerfect architecture, AudioCodes’ underlying, best-of-breed, core media gateway technology for all of its products.
Deliver Feature-Rich Solutions
The AC482xx voice over packet processor combines up to four channels of toll quality low bit rate voice compression, with a G.168-2002 compliant echo canceller, and complete voice band processing functions in a single device. With configurable tail length of up to 64 msec, the AC482xx delivers an adaptive, state of the art echo canceller. Field-proven G3 Fax Relay, compliant with the T.38 ASN.1 standard, is a major enhancement to the AC482xx 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 AC482xx is supported by the VoicePacketizerTM software stack which enables the processor to create a VoIP-compliant media stream as part of a Media Gateway entity. The VoicePacketizerTM 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 AC482xx and for run-time call control. The VoicePacketizerTM enables easy control of the packet processor
and fast time-to-market.
Software Upgrades
The complete functionality of the multi-channel processor is implemented in the internal firmware, which is downloaded into the processor by the host prior to start of the operation. This allows the addition of new features in future product releases without 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.
