REPEATER, CAN COMMUNICATION SYSTEM, AND METHOD FOR TRANSMITTING A DATA TELEGRAM WITHIN A CAN COMMUNICATION SYSTEM

The invention relates to a repeater (2, 2') for a communication system with at least one network (1, 1') for forwarding a data telegram comprising a recessive ACK bit from a first participant (A) to a second participant (B) either within the network (1) or in order to connect two similar networks (1, 1'), said repeater being designed to forward data telegrams on bit transmission levels of the ISO-OSI reference model. The repeater comprises at least two transceivers (5A, 5B) for physically coupling the repeater (2, 2') to the at least one network (1, 1'), said repeater (2, 2') comprising a logic unit (6) which is designed to detect the determined structure of a data telegram to be forwarded from the first participant (A) to the second participant (B) and to emulate an ACK bit and transmit same to the first participant (A) at a determined point in time before or while the recessive ACK bit of the data telegram is received.
