1. To demonstrate the V 42 error correction protocol on a noisy line an error injector can be used It inverts bits of input and output data once per time period When V 14 protocol is used some garbage symbols may occur on the terminal When V 42 protocol is used no garbage will occur on the terminal but data transfer will be paused from time to time damaged data will be retransmitted automatically To switch on the error injector V42_TX_ERROR_INJECTOR and V42_RX_ERROR_INJECTOR constants have to be defined in the v42 h file line 20 Example define V42_TX ERROR INJECTOR define V42_RX ERROR INJECTOR For normal operation do not forget to delete these definitions 7 MCF5407 Low Data Rate Soft Modem Quick Start Guide MOTOROLA For More Information On This Product Go to www freescale com Freescale Semiconductor Inc HOW TO REACH US USA EUROPE LOCATIONS NOT LISTED Motorola Literature Distribution P O Box 5405 Denver Colorado 80217 1 303 675 2140 or 1 800 441 2447 JAPAN Motorola Japan Ltd SPS Technical Information Center 3 20 1 Minami Azabu Minato ku Tokyo 106 8573 Japan 81 3 3440 3569 ASIA PACIFIC Motorola Semiconductors H K Ltd Silicon Harbour Centre 2 Dai King Street Tai Po Industrial Estate Tai Po N T Hong Kong 852 26668334 TECHNICAL INFORMATION CENTER 1 800 521 6274 HOME PAGE http Awww motorola com semiconductors Information in this document is provided solely t2. 420 1500 1 V 21 FSK 300 300 1080 1750 1 e ITU T V 21 V 23 V 22 and V22bis Physical Handshake Sequences e ITU T V 42 Error Correction e ITU T V 42bis Data Compression 2 MCF5407 Low Data Rate Soft Modem Quick Start Guide MOTOROLA For More Information On This Product Go to www freescale com Freescale Semiconductor Inc Related Files 1 2 ITU T V 14 synchronous to asynchronous converter AT command set Tone generation and detection DTMF and Pulse dialing DAA interface Si3044 Modem Daughter Card via the MCF5407 USART module DTE interface via the MCF5407 UART module Related Files The following files are relevant to Soft Modem project main c entry point of the Soft Modem modem h high level functions and main data structure definitions modem c implementation of high level functions state_machine h definition of state machine data structure state _machine c implementation of main state machine v21 h definitions used by V 21 protocol v21 c initialization of V 21 data pump protocol and realization of physical handshake sequence for V 21 v23 h definitions used by V 23 protocol v23 c initialization of V 23 data pump protocol and realization of physical handshake sequence for V 23 v22 h definitions used by V 22 protocol v22 c initialization of V 22 data pump protocol and realization of physical handshake sequence for V 22 v22bis h definitions us
