V.29 Fax Software Using the Group 3 Fax Modulation Technique

The fax modem software consists of both transmission and receiving functions for symbol transfer in groups of 2 or 4 bits at rates of 2400 symbols per second respectively. It operates in either half or full duplex modes and has a "quick connect" feature.

Using the Group 3 fax (G3 fax) modulation technique, it offers fax data transfer at 9600 bps and 7200 bps on two-wire lines. The fax software is available for a number of DSP and microprocessors. 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.

Additionally, it can operate within a multi-tasking environment or as a stand-alone task and is highly optimized for fixed-point arithmetic.

This fax modem software belongs to GAO's family of Fax Software. Other products in the line include V.27, V.17 and V.34 fax software whose maximum bit rates are 4.8, 14.4 and 33.6 kbps. This line also includes T.30/T.30E and T.4 fax modem protocols, and T.38 fax relay protocols. The family provides the most comprehensive and unique suite of modem, fax, telephony, speech software, VoIP, FoIP, fax relay and fax/modem/voice relay software for embedded applications for DSP and microprocessors.
