ABSTRACT:
A method for transmitting digitally coded analog signals which are combined in coding blocks in a digital packet multiplex system permits transmission of coding blocks having a length which does not correspond to the normal useful packet length. In such an instance, packets having a different content are generated and information identifying such packets is transmitted to the receive side of the system in the form of a designated number of bits in the existing available transmission capacity of the beginning of the packet, so that the beginnings of the coding block can be recognized at the receive side.
