AC4880x
The AC4880x is an ideal low cost voice processing engine for a variety of Voice over IP, Voice over DSL and other voice over packet client applications. The AC4880x VoP processor is a one or two port 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 4880x is based on VoIPerfect architecture, AudioCodes’ underlying, best-of-breed, core media gateway technology for all of its products.
Deliver Feature-Rich Solutions
The AC4880x voice over packet processor combines one or two 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 AC4880x 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 AC4880x 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 AC4880x and for run-time call control.
Software Upgrades
The complete functionality of the AC4880x is implemented in the internal DSP software. The software image is downloaded into the AC4880x 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
over 12 million VoP ports to date.
