canceller, and complete voice band processing functions in a single device.
With configurable tail length of up to 40 msec, the AC481xx 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 AC481xx 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 AC481xx 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么 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 AC481xx and for run-time call
control. The VoicePacketizer
TM
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.
