Abstract

Controlling an unreliable data transfer in a data channel from a transmitting unit to a receiving unit. A bypass mode or a buffer mode is activated depending on the error rate in the data channel. If bypass mode is selected, data packets are directly transferred in probation from the transmitting unit to the receiving unit by a bypass line. The data packets are error checked after the data transfer. If buffer mode is selected, data is transfer from the transmitting unit to the receiving unit by a buffer line via an error detecting and correcting unit and a buffer unit. The errors are detected and corrected during the data transfer.
