Abstract: Data communications are effected over one or more network branches to ensure appropriate receipt of data at different devices on the network. In accordance with an example embodiment, time-based communications are effected for a plurality of different network devices, at least two of which are connected to a common wired network link, with each network device being assigned to communicate during different time slots within a communication cycle. Each communication received on the common wired network link is assessed as being error-indicative or not error-indicative. In response to a received communication on the common wired network link being assessed as being error-indicative, the common wired network link is operated to corrupt data received on the branch, such as by driving the branch during a time slot in which the error-indicative communication is received, therein ensuring that other network devices disregard the data received during that time slot.

Abstract: Methods and devices for processing and retransmitting highway communication system transmissions include determining a reliability of a received message and including an indication of the reliability in retransmitted transmissions. Reliability of received messages may be based on a signal strength of the received peer transmission, comparison of the signal strength to a distance to the transmitter based on message contents, the age of the received message, the signal quality of the received message, and other parameters. An indication of the determined reliability may be included in retransmissions of the message to enable other vehicles and receiver units in the highway communication system to benefit from the reliability determination. Message reliability may be used as part of prioritizing messages for processing. Messages may be processed according to priority so that high priority messages are processed before lower priority messages.

Abstract: A line status monitoring circuit receives a frame through one of a number of lines from another node connected through a redundant transmission channel which is made redundant by the lines. The line status monitoring circuit includes a line-specific check frame monitoring unit. If a line-specific check frame having an added dedicated header corresponding to each of the plurality of lines is received through one of the lines from another node, the line-specific check frame monitoring unit determines whether or not a further line-specific check frame corresponding to a frame for checking which is identical to a frame for checking to which the line-specific check frame corresponds is received through at least a predetermined number of lines within a predetermined time. If the further line-specific check frame is not received in this manner, the line-specific check frame monitoring unit discards the frame.
