Highly Optimized V.27ter Fax Modem Software

PRLog (Press Release) - Feb 03, 2010 -
Toronto, Canada - GAO Research Inc.'s (www.GAOResearch.com) upgraded version of V.27ter fax modem software is widely used in the general switched telephone networks. It implements the ITU-T V.27ter Recommendation and uses the Group 3 facsimile (G3 fax) modulation scheme for fax image transfer at 4800bps and 2400bps. The software is highly optimized in C and multi-channel ready. It supports commonly used processors such as TI C5000 & C6000 series DSPs, ARM processors and ADI DSPs and OS such as Windows and Linux.
GAO V.27ter fax modem software 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. The fax modem software consists of transmission and receiving functions for symbol transfer in groups of 2 or 3 bits at rates of 1200 or 1600 symbols per second respectively. Optional backward channel modulation rate is up to 75 symbols per second. This fax modem software can be integrated with other GAO data modems, telephony, speech compression, and fax relay solutions for use in various applications.
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.
