Digital Voice Systems AMBE-3000 HDK Brochure & Specs page 2

Voice Activity Detection (VAD), adaptive Comfort Noise
Insertion (CNI) and support for DTMF tones. This level of
performance has resulted in the successful deployment of
wireless communication systems in the most demanding
environments.
The AMBE-3000™ HDK vocoder board is equipped with industry
standard connections for fast and easy setup and operation.
An RCA jack and a handset connection allow analog voice
input/output for encoding/decoding real-time speech. A RS-
232 serial port is the data channel that delivers the compressed
bit stream between two AMBE-3000™ HDKs for real-time full
duplex communication. With the USB interface users can
connect the AMBE-3000™ HDK to a PC, to configure the channel
interface, encode (record) an analog input to a compressed
data file, and decode (playback) previously encoded files.
There are be a number of ways to configure the AMBE-3000™
HDK hardware. The user can select the vocoder rate and
control a variety of vocoder features from either a PC
connected to the USB interface or through dip switches and
jumpers. Additionally, the board provides test points for
extensive circuit probing and monitoring of data. All these
capabilities are ideal for comparing voice quality at various
rates, analyzing the compressed voice data I/O stream and
establishing customized interface requirements.
The AMBE-3000™ HDK is a complete hardware and software
package solution, with off-the-shelf availability. The
development kit includes the evaluation board, schematic
details, software routines for the on-board Microcontroller
(user is able to to recompile the AMBE-3000™ HDK source code
to achieve custom configurations), as well as reference circuit
designs. Documentation includes the AMBE-3000™ HDK User's
Manual that describes the hardware and software features
and a Software Manual to explain details of the included
software source code.
