Abstract

Method for the transmission of a telefax message. The method is used for transmitting a telefax message from a telefax terminal equipment (TF) at a transmission side to a plurality of telefax terminal equipment (RF1 . . . RFn) at a reception side. The telephone numbers of the telefax terminal equipment (RF1 . . . RFn) are input into an operating unit (KB) of the telefax terminal equipment (TF) of the transmission side and are stored in a data area (COMFIL). Picture elements of the on original telefax message are converted into electrical picture signal elements and are intermediately stored in a further data area (NA) allocated to the first data area (COMFIL). A controller (CC) generates second image signal elements from every telephone number and converts these into, in particular, an original telefax message page format. The second and the first image signal elements are transmitted together to the telefax terminal equipment of the reception side identified by the telephone number.
