Toronto, Canada (PressExposure) September 18, 2009 -- GAO Research Inc. (www.GAOResearch.com) has upgraded its widely-deployed V.17 Fax Modem software which implements the ITU-T V.17 recommendation for a two-wire modem for facsimile applications with data rates up to 14,400bps. This international standard defines the operating sequences and modulation techniques to be used in high speed fax applications.
GAO's V.17 fax software operates at a frequency of 1800Hz and supports V.24 interchange circuits. QAM is used for the channel with synchronous line transmission at 2400 baud. Exchange of rate sequences is provided during start-up to establish the data-rate, coding, and any other special facilities. The trellis coding rates are from 7200 to 14000bps and modulation rate is 2400 symbols/s. All GAO software are subject to the most stringent quality control procedures, which is reflected in its well structured code, detailed design documentation, and well-defined design and test plans. This ensures ease of integration into the user's system, easy maintenance, and a smooth upgrade path for next-generation products.
GAO V.17 soft fax modem solution can operate within a multi-tasking environment or as a stand-alone task and is optimized for fixed-point arithmetic. It supports most commercial analog front ends (AFE) as well as proprietary discrete DAAs with codecs, depending upon the application. It can be integrated with other GAO data modems, telephony, speech compression, and fax relay solutions for use in various applications.
The software supports commonly used processors such as TI C5000 & C6000 series DSPs, ARM processors and ADI DSPs and OS such as Windows, VxWorks, and Linux.
