Process for the transmission of digital data over several data transmission networks, conjugated and conjugated units programmes ".The present invention relates to a process in which the useful data are initially transmitted at a first data transmission network (12) to a first transfer unit of the network (22, 24). The useful data are encoded according to a first kind of encoding.The transfer unit of the network (22, 24) leads the useful data in a transmission network switching directly (16) without recoding.For the transmission network direct switching is signalled the sort of the original coding and a second kind of coding is permitted in the transmission network of direct switch (16).The signalling for the first kind of encoding is transmitted through the transmission network direct switch (16), without processing, to another transfer unit of the network (44)46). The useful data are transmitted in a data transmission network (16), in such a way, as if they were coded according to the type of coding is permitted.
