The invention relates to a method for transmitting data from a data source to a data sink in a digital terminal via a data line, within a communications time slot of a time multiplex system. A predetermined no-load data item applied to the data line indicates a no-load state in which no data is transmitted. The inventive method comprises the following steps: transmitting a transmit data item to be transmitted from the data source to the data sink via the data line if said transmit data item does not correspond to the no-load data item, or logically combining the transmit data item with a combination data item to form a representation data item if the transmit data item does correspond with the no-load data item; and then transmitting an indicator data item and the representation data item from the data source to the data sink, in succession; temporarily storing a receive data item applied to the data line in the data sink for data processing if the receive data item is not identical to the indicator data item or inversely logically combining the representation data item following the receive data item with the combination data item to form the original transmit data item if the receive data item is identical to the indicator data item and temporarily storing the transmit data item formed from the representation data item by inverse combination for further data processing in the data sink.
