Abstract

A method is provided for localizing a physical network fault in a network having a plurality of network participants. The method comprises detecting by a first network participant and a second network participant that communication with a third network participant and the respective further participant of the first and second network participants is disrupted. In response to the detecting, the first network participant and second network participant automatically reduce their baud rate. The method comprises further establishing a connection between the first network participant and second network participant with use of the reduced baud rate, detecting by the first network participant and/or the second network participant that communication with the third network participant is not possible with use of the reduced baud rate, and storing information on the impossibility of communication with the third network participant.
