摘要： A system (e.g., Fibre Channel Error Detecting Code (FC-EDC)) that maps the "standard" Hamming codes onto the bits of a 33-bit control block is provided. The system employs a "rotation" of the check positions in a two-dimensional parity-check matrix for the FC-EDC. The specification discloses a computer-implemented program to test further modifications and permutations of the "standard" distance-4 parity-check matrix to yield an FC-EDC with enhanced error-detecting properties, designed to detect the most likely errors in the known physical environment. By using a parity-check matrix with the "rotation" property, certain error-detecting properties of the parity-check matrix are ensured, and the computation time for searching for a matrix with enhanced error-detecting properties becomes much shorter.

摘要： In a wired data telecommunication network power sourcing equipment (PSE) coupled to a powered device (PD) carries out an inline power discovery process to verify that the PD is adapted to receive inline power, then a plurality of classification cycles are carried out to convey a series of inline power classes back to the PSE. The series of inline power classes may all be the same, in which case the PD is legacy equipment and is adapted to receive the power level corresponding to that class. If they are not all the same, information is thus conveyed to the PSE which may, for example, correspond to a specific power level to be applied or to other information.

摘要翻译：在有线数据电信网络中，耦合到受电设备（PD）的供电设备（PSE）执行内联电力发现过程以验证PD适于接收内联电力，然后执行多个分类周期以传达一系列在线功率类别返回到PSE。一系列在线功率级别可以全部相同，在这种情况下，PD是传统设备，并且适用于接收对应于该级别的功率级别。如果它们不完全相同，则信息因此被传达给PSE，其可以例如对应于将被应用的特定功率水平或其他信息。
