VOCAL’s V.34 fax/facsimile software implements a high speed fax modem used on GSTN and on point-to-point 2-wire leased telephone-type circuits
VOCAL’s V.34 fax/facsimile software implements recommendation ITU-T V.34 which defines the modulation methods and operating sequences for a fax modem used on General Switched Telephone Networks (GSTNs) and on point-to-point 2-wire leased telephone-type circuits.
The V.34 fax modem software uses state-of-the-art line probing analysis to automatically determine maximum channel capacity. It also supports MSE fallback/fallforward threshold control to adjust the tradeoff between higher data channel rates and symbol error rates. V.34 channel separation is accomplished using echo cancellation techniques.
