Abstract: A resynchronization device for an Ethernet network device with a transmitter and a receiver includes a detector that detects faulty code groups received by the receiver. A counter counts the faulty code groups that are detected by the false carrier detector during a predetermined period. A resynchronization trigger asserts a resynchronization signal if the counter exceeds a predetermined threshold during the predetermined period. The faulty code groups include false carriers, which include non-idle code groups other than frame delimiters. Alternately, the faulty code groups include idle code groups that match idle code groups generated by the transmitter of the local network device.

Abstract: A method for data interleaving and data de-interleaving against periodical position interference, the process of data interleaving includes: multiplexing data of different transport channels, interleaving the data multiplexed, and outputting the data interleaved; the process of data de-interleaving includes: receiving the data interleaved, de-interleaving the data received, and de-multiplexing the data de-interleaved into different transport channels; performing a randomized operation in the process of the data interleaving and an inverse operation of the randomized calculation in the process of the data de-interleaving to make the outputted position of the data of different transport channels after the interleaving be random. It may be avoided by applying the present invention that all synchronization interference signals in a wireless channel are concentrated in the data of the same transport channel.

Abstract: A power sourcing equipment-powered device (PSE-PD) combination unit requests inline power from a connected PSE or other PSE-PD combination unit by having the PD portion of the PD-PSE combination unit adapt its electrical characteristics, if necessary, to obtain the maximum power available. The PD-PSE combination device keeps track of available power less power consumed locally with a summation unit. A PSE manager unit grants PD power requests from downstream devices based upon the available power left (e.g., original PSE power less losses less local consumption).

Abstract: In a multicarrier communication network, specific subcarriers are dedicated for use in carrying burst descriptor information. A subscriber station in the network may monitor the dedicated subcarriers to determine when a burst involving the station is to occur. By using dedicated subcarriers for burst information, scheduling decisions can be made closer in time to the actual bursts.

Abstract: This method of managing malfunctions in a telecommunications network is implemented in a router having a plurality of communication interfaces and a nominal operational routing plan that is duplicated on its interfaces. The method comprises the following steps that are performed during nominal operation: a step of calculating a secondary operational routing plan for degraded modes of operation; and a step of transferring secondary plans to each of the interfaces; and in the event of a malfunction being detected, a step of causing all of the interfaces to switch from the nominal plan to a secondary plan that corresponds to the degraded mode of operation that results from the detected malfunction.
