Abstract: Embodiments included herein are directed towards an automatic tire inflation monitoring system and method. The method may include confirming, using a battery powered electronic sensor, that there is no active tire re-inflation in progress. The method may further include monitoring, using the battery powered electronic sensor, the status of all tire pressures over a period of time and determining, using the battery powered electronic sensor, whether a rate of tire pressure reduction exceeds a first value. The method may include reporting, using the battery powered electronic sensor, a fault if the rate exceeds the first value.

Abstract: Described are a system and method for forwarding K-bytes between optical cards in a communication system. The system includes a first card and second card each connected to a backplane. The second card obtains protection-signaling information from an incoming signal arriving at the second card from over a network. The second card generates an out-of-band signal having the protection-signaling information, and transmits the out-of-band signal having the protection-signaling information to the first card in the network element. In one embodiment, the first card is a cross-connect card, and the cross-connect card simultaneously transmits the out-of-band signal with the protection-signaling information to a plurality of cards in the system.

Abstract: A first aspect of the invention provides a system for prioritising faults in a transport network comprising network elements arranged to transport data signals comprising respective overhead data and payload data. The system comprises one or more first network elements arranged to include in said overhead data a priority indicator indicating the relative importance of the respective payload data. The system further includes one or more second network elements arranged to examine the respective priority indicator of data signals in respect of which a fault is detected. Detected faults are prioritised using the respective value of the priority indicator and hence on the relative importance of the information carried by the faulty signal.
