Abstract: The invention relates to active star coupler based network handling of redundancy in the physical layer by transmitting a message to both regular and redundant links. In an error free case, the message is forwarded by the regular interface, while the redundant link, is blocked. Each interface is equipped with link failure detection logic. If a link failure is detected, an incoming message is blocked and the affected interface controls the interface connected to the redundant link to take over message forwarding. If the link recovers, the regular interface takes over forwarding responsibility and the redundant link is disabled.

Abstract: The invention relates to a network comprising a plurality of network nodes. At least part of the network nodes are directly coupled to each other via at least one star node. The star node comprises a plurality of star interfaces which are assigned to at least one network node. In dependence on a respective pilot signal, a star interface conveys a message from the assigned network node to the other star interfaces, or from another star interface to at least one of the assigned network nodes. Also, in the event of simultaneous arrival of at least two pilot signals at the respective star interfaces, a decision circuit releases one star interface for the transmission of data.

Abstract: In order to further develop a communication system (400) as well as a corresponding communication method in such way that a protection of the communication medium (300, 310) from timing failures of a communication controller (120) of a node (100), in particular a limited protection of the communication channel (300, 310) from illegal transmissions in the time domain, can be achieved without providing any bus guardian, it is proposed to prevent any transmission of the node (100) during phases with high susceptibility to illegal transmission, in particular during the communication startup of the communication system (400).

Abstract: The invention relates to a communication system with at least two communication nodes for the transmission of information via a common transmission medium in a time division multiplex process. During the system start, at least one node is provided for monitoring whether a first signal which utilizes at least one slot in a regular manner is already present in the transmission medium. If a first signal is present, said node is designed for testing this first signal as to its integrity and said node is designed for sending a second signal in the case of an incorrect integrity of the first signal, and a programmable position within the time frame given by the second signal is allocated to the time slot utilized by the first signal.

Abstract: The invention refers to a method for monitoring a communication media access schedule of a communication controller (5) of a communication system (1) by means of a bus guardian (6). The communication system (1) comprises a communication media (2) and nodes (3) connected to the communication media (2). Each node (3) comprises a communication controller (5) and a bus guardian (6) assigned to the communication controller (5). Messages are transmitted among the nodes (3) across the communication media (2) based on a cyclic time triggered communication media access scheme.

Abstract: The invention concerns a network comprising an interconnecting network and several network nodes that are coupled to said interconnecting network and are designed to adapt their local communication time schedule to the communication time schedule of at least one other network mode, prior to being integrated as active network nodes. A network node to be integrated checks the activity of other network nodes and if no activity is identified, sends out positional messages for other network nodes, said message being fixed by predetermination in its communication time schedule. If a network node cannot be integrated as a reference node, it can only be integrated as an active node if it adapts its local communication time schedule to that of the reference node after receiving positional messages and if a check as to whether its own communication time schedule agrees with the communication time schedules of at least some of the active network nodes proves positive.

Abstract: The invention relates to a communications network with at least two network nodes, between which data may be transmitted via a transmission medium, in which a communications schedule is provided which allots time slots to the network nodes for access to the transmission medium, in which the network nodes each comprise at least one communication controller with a first scheduler for controlling access by the network nodes to the transmission medium according to the communications schedule, in which the communications network comprises at least one bus guardian with a second scheduler for monitoring accesses by the network nodes to the transmission medium according to a monitoring schedule, in which the communication controller comprises means for generating a local, independent clock signal and a global clock signal, which may be influenced by at least one parameter of the communications system and in which the global clock signal is provided both to control the first schedulers of the communication control

Abstract: In order to provide a method for transmitting messages between a number of nodes (1, 2, 3, 4) of a network over two channels (A, B) which ensures reliable message transmission even in the event of a failure of one of the two channels (A, B), it is proposed that, in the event of a failure of one channel (A, B), messages are transmitted over the other channel (B, A).

Abstract: A dual-channel network with in each case one communication controller (2, 6) for each of the two channels (A, B). In order to ensure that the two channels (A, B) operate on a temporally matched basis, an exchange of current states (“ready, “abort”) takes place via an external or an on-chip interface (1a, 1b). The cold start operation is carried out only if, and so long as, both communication controllers are in the “ready” state.

Abstract: A method and a bit stream decoding unit for bit stream decoding has a bit stream comprising a number of consecutive samples. In order to provide for rapid and, in particular, reliable decoding of the bit stream, a detection window comprising a number of samples is defined and the detection window is positioned at certain positions on the bit stream in order to comprise certain samples with respective sample values. A majority voting is applied to the sample values in the detection window and, in dependence on the result of the majority voting, the bit stream is decoded and respective bit values are generated.
