China., February 24, 2013 - (PressReleasePoint) -V.27ter Fax Modem Software
Toronto, Canada - GAO Research Inc. ) recommends its V.27ter fax modem software used in the general switched telephone network. This fax modem software can also be integrated with telephony, speech compression, and fax relay solutions for use in various applications in communications and telecom.
This V.27ter fax modem software implements the ITU-T V.27ter fax recommendation which incorporates a modem operating at either 4800 bps or 2400 bps. It operates at a reduced rate of 2400 bps with four phase differentially encoded modulation and uses a data signaling rate of 4800 bps with eight phase differentially encoded modulation. It is the modulation scheme used in Group 3 facsimile (G3 fax) for image transfer at 4800 bps and 2400 bps.
This fax modem software 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 a rate of 1200 or 1600 symbols per second respectively. It also features optional backward channel at modulation rates of up to 75 symbols per second. In addition, it is highly optimized in C and is multi-channel ready.
This V.27ter fax modem software belongs to GAO's family of Fax Software. This line also includes V.17 Fax Software implementing the ITU-T V.17 recommendation for a two-wire modem for facsimile applications with rates up to 14,400 bps, V.29 Fax Software implementing the ITU-T V.29 Recommendation which provides full-duplex data transmission at rates of 9600, 7200, and 4800 bps over 4-wire leased lines and V.34 Fax Modem Software that incorporates a higher level of optional capabilities, intelligence, and adaptability than the lower V.series modems to make the best use of the available conditions.
