Patent ID: 7468949

Claim:
A method for media-redundant operation of a terminal in a network, comprising: automatically monitoring, via a first transmission device in the terminal, which is connected to a media access controller for the terminal, a connection which is formed between the first transmission device and a network component via a first connecting medium; producing, from the first transmission device, a failure signal if no connection or a faulty connection is found via the connecting medium during automatic monitoring of the connection, and as a reaction to the failure signal, deactivating the first transmission device via a control device which is connected to the first transmission device; activating, via the control device, a further transmission device, which is connected to the media access controller for the terminal, with a sound physical connection being reproduced between the terminal and the network via a further connecting medium, and sending an electronic failure message by means of the further transmission device via the further connecting medium to the network for registration of the further transmission device, wherein the further network components in the network analyze the failure message and adapt their MAC address addressing tables on the basis of the failure message in such a way that data packets which are addressed to the terminal are passed on to the further connecting medium.
