2 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 eia-470b dtmf dialer extension-in-use detection control tonal ringing generator command/control interface via at commands or direct function calls performance application program (words) data (words) mips caller id type 1-2 software module 2820 257 9.6 caller id parser software module 1440 550 -- generic echo canceller software module (with 8ms tail length) 850 800 12.0 full duplex speaker phone software module (with 24ms tail length) 1650 930 15.0 feature phone application software 1760 1310 1.0
motorola feature phone product brief 3 ? 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. product documentation the following documents are required for a complete description and proper design with the feature phone application and modules. documentation is available from local motorola distributors, motorola semiconductor sales offices, motorola literature distribution centers, or online at www.motorola.com/ semiconductors/ . topic description order number dsp56800e reference manual detailed description of the 56800e architecture, 16-bit dsp core processor and the instruction set dsp56800erm/d targeting motorola dsp5685x platform focuses on specifics of target configuration for motorola?s dsp56852 and dsp56858 devices available on sdk cd order # re10118si dsp56852 user?s manual detailed description of the memory, peripherals, and interfaces of the dsp56852 dsp56852um/d dsp5685x user?s manual detailed description of the memory, peripherals, and interfaces of the dsp5685x family of devices dsp5685xum/d dsp5685x evaluation module user?s manual describes in detail the hardware on the dsp56852evm and dsp56858evm dsp56852evmum/d dsp56858evmum/d feature phone application application documented in targeting manuals available on sdk cd order # re10118si programmer?s guide describes the development environment, software modules and tools for the dsp568xx devices and the application programming interfaces (apis) sdk101/d gr-30-core gr-30-core, lssgr: voiceband data transmission interface section 6.6 (a module of lssgr, fr-64), telcordia technologies, december 1998. www.telcordia.com sr-3004 sr-3004, testing guidelines for analog type 1, 2, and 3 cpe as described in sr-ins-002726 (a module of adsi, fr-12), telcordia technologies, january 1995. www.telcordia.com sr-tsv-002476 sr-tsv-002476, cpe compatibility considerations for the voiceband data transmission interface, telcordia technologies, december 1999 www.telcordia.com
