AC486xx
The AC486xx is an ideal solution for a single T1 or E1 Trunking Gateway, as well as a building block for high-density, carrier class Voice over IP gateways. Featuring high channel density, low power consumption and a compact footprint, the AC486xx enables the building of cost effective, low power high-density gateways, access devices and routing/switching equipment,
without requiring an external RAM. Field-proven, feature-rich software enables the rapid development and fast time-to-market of the complete solution. The AC486xx is based on VoIPerfectTM architecture, AudioCodes’ underlying, best-of- breed, core media gateway technology for all of its products.
Deliver Feature-Rich Solutions
The AC486xx voice over packet processor combines up to twenty-four channels of toll quality low bit rate voice compression or forty-eight G.711 channels, 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 128 msec, the AC486xx 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 AC486xx offering. Other advanced features include selection of Vocoders on the fly for each channel, 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 AC486xx 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 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 AC486xx and for run-time call control.
New IPmedia Features
The AC486xx offers a new set of media processing technologies, such as fast/slow voice playback, announcements, automatic gain control, energy detector, answer detector, PCM pattern detector and packet to packet transcoding. These features enable developers of Media Server Platforms to exploit AudioCodes’ vast experience in the voice over packet market for
significantly shortening their time-to-market.
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.
