V.29 Fax Software (V29 Fax Modem)

GAO V.29 fax modem software implements the ITU-T V.29 Recommendation, which provides full-duplex data transmission at rates of 9600, 7200, and 4800bps over 4-wire leased lines. GAO’s V29 modem data pump software has “quick connect” feature. It is also the modulation technique used in Group 3 fax (G3 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 (referred to as symbols) at rates of 1200 or 1600 symbols per second respectively.
