DESCRIPTION
The DS2132A Digital Answering Machine Processor is
a Digital Signal Processor (DSP) optimized for the com-
pression/expansion of PCM coded voice to/from an ex-
tremely low bit rate. The DS2132A contains two ad-
vanced speech compression algorithms that offer
outstanding fidelity. The Standard Record/Playback al-
gorithm compresses speech to 9.8Kbps and the Ex-
tended Record/Playback algorithm compresses
speech to 4.9Kbps.
The DS2132A is ideal for embedded applications such
as digital answering machines, voice mail, voice annun-
ciators, and any other device that needs to maximize
speech storage in a limited memory space. A simple
three wire interface to the embedded microcontroller
frees up valuable controller port pins for other uses and
simplifies the software needed to transfer speech data,
issue commands, and receive DTMF/energy level/sta-
tus information. The DS2132A detects and generates
all 16 DTMF tones and can also generate a wide variety
of call progress tones. In addition, the DS2132A pro-
vides CCITT Rec. T.30 FAX calling tone detection which
enables the answering machine to determine if the in-
coming call is a voice or FAX transmission. The energy
level detector allows the microcontroller to perform call
progress detection and automatic gain control func-
tions.
