Product Description
The feature phone application is a fully functional telephone based on the DSP5685x family that
incorporates a high quality full duplex speakerphone and CLASS feature support compliant with Telcordia
SR-3004 and SR-TSV-002476. The feature phone application provides a highly flexible framework for
screenphone and telco service products that permits device manufacturers to quickly add a custom user
interface and value-added convenience features, such as number and call log directories, voice announce for
caller ID, and digital answering/paging functions. The feature phone application can be expanded to support
multi-line applications with multi-line conferencing. Feature phone compatibility with telephone networks

Feature Phone Product Brief
MOTOROLA
is worldwide for call origination, call termination and speakerphone operation. Feature phone CLASS
features are compatible with GR-30-CORE compliant networks (North America). Figure 1 illustrates the
system diagram of the feature phone.
The feature phone application is a customizable framework that uses four telephony DSP modules. The
application software contains the main control loop and a real-time kernel that manages the telephone state
and makes calls to dedicated SDK modules to perform various functions. The application software performs
all start-up initialization and buffer allocation for the telephony modules and hardware drivers. It
implements the communications between device and peripheral drivers and the telephony modules.
The feature phone application communicates with the telephony modules through a well-defined API. All
input commands and data samples are passed to the modules through one of three data structures contained
within the function calls. These data structures are used by the modules to perform their function and pass
telephony events such as Caller ID information back to the application software. A simple serial control
interface using AT commands is provided to simplify integration into existing products that contain a host
controller.
Other features include:
An adaptive line echo canceller with a preset tail length of 16 ms that is adjustable in 8ms intervals
up to 64ms
An acoustic echo canceller with a preset tail length of 24ms that is adjustable in 8ms intervals up to
64ms

"Best in Class" Development Environment
The Software Development Kit (SDK) provides fully-debugged peripheral drivers, libraries and interfaces
that allow a programmer to create his own unique C application code independent of component
architecture. The Feature Phone Application is a premium component of the SDK. The CodeWarrior
Integrated Development Environment is a sophisticated tool for code navigation, compiling, and debugging.
A complete set of evaluation modules (EVMs) and development system cards will support concurrent
engineering. The Feature Phone Application is supported with either the DSP56852EVM or the
DSP56858EVM and the Telecommunications Daughter Card (TDC1). Together, the SDK, CodeWarrior,
and EVMs create a complete, scalable tools solution for easy, fast, and efficient development.
