Fax Standards (ITU-T Recommendations)
International FAX standards (ITU-T recommendations) include G1 to G4. G1 to G3
use analog telephone networks. G4 uses a digital telephone network (ISDN). G3 is
the standard currently in greatest use. FAXes conforming to Super G3, a recently
added standard, are equipped with a fast 33.6kps modem and reduce
transmission times to about half those of G3 FAXes.
