ABSTRACT:
In a method for operating a digital data transmission network, and in a digital data transmission network operating according to the method, in an initial part of a transmission event between a control unit and at least one user unit in the network, a first data block containing data and a second data block containing data are transmitted from the control unit to the user unit. In the control unit, a first reference number is prescribed as a first transmission parameter in the first data block, which identifies a number of bit places provided for subsequent data transmission of the data contained in the first block from the user unit in a first useful channel. The control unit also prescribes a second reference number as a second transmission parameter in the second data block, identifying a number of bit places for subsequent data transmission of the data contained in the second block from the user unit in a second useful channel. The first and second data blocks are transmitted from the control unit to the useful unit and the first and second reference numbers are stored in the user unit. Following an end of the transmission event, the user unit employs the number of bit places indicated by the first reference number for data transmission of the data contained in the first data block in the first useful channel, and employs the number of bit places indicated by the second reference number for data transmission in the second useful channel of the data contained in the second data block.
