Upgraded Fax Modem Software Implements ITU-T V.29 Recommendations

Toronto, Canada – GAO Research Inc. (www.GAOResearch.com) has recently updated its fax modem software supporting commonly used processors such as TI C5000 & C6000 series DSPs, ARM processors and ADI DSPs and OS such as Windows and Linux. It implements the ITU-T V.29 Recommendation, which provides full-duplex data transmission at rates of 9600, 7200, and 4800bps over four-wire leased lines. The soft modem software is also modulation technique used in Group 3 fax for fax data transfer at 9600bps and 7200bps on 2-wire lines. It consists of transmitting functions and receiving functions which are called to transmit/receive bits in groups of 2 or 3 at rates of 1200 or 1600 symbols per second respectively.
GAO Research’s V.29 modem data pump software operates in either half or full duplex modes and has a “quick connect” feature. It uses amplitude and phase modulation for synchronous transmission. The V.29 soft fax modem solution operates within a multi-tasking environment or as a stand-alone task and is optimized for fixed-point arithmetic. It can be integrated with other data modems, telephony, speech compression, and fax relay solutions for use in various applications.
All GAO’s 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.
