AudioCodes Enabling Technology Products
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.
Deliver Feature-Rich Solution
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.168-2000 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 VoicePacketizer
TM
software stack which
enables the processor to create a VoIP-compliant media stream as part of a
Media Gateway entity. The VoicePacketizer
TM
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
TM
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
close to 10 million VoP ports to date.
