According to the ITU recommendations for SDH or SONET, a payload exceeding the transmission capacity of the largest virtual container can be divided over several concatenated virtual containers. According to a method for the transmission of such a payload via a synchronous information transmission network (NET), the payload is divided into blocks and the individual blocks are packed into virtual containers (VC4), each of which has a path overhead and a payload field, and are transported as a virtual concatenation in at least one transport module. A pointer (Z) that points to the next virtual container in the concatenation is inserted in the path overhead of all virtual containers (VC4) except the last virtual container in the concatenation. This makes it possible to change the number of concatenated virtual containers (VC4) during a connection.
