Petersen There are two papers I know about: CCITT Recommendation T.4 : 1988, Standardisation of Group 3 Facsimile apparatus for document transmission. CCITT Recommendation T.6 : 1988, Facsimile coding schemes and coding control functions for Group 4 facsimile apparatus. You can get those papers via your local PTT connections...
