摘要： A novel mechanism for detecting the presence of powered devices over a network. A unique, infinite pseudo-random sequence of pulses are generated and transmitted over the network to the link partner attached to the other end of the cable. At each time unit, the PSE decides whether or not to transmit a pulse at that time. Thus, the pulses generated have pseudo-random inter-pulse delays between them. In addition, each pulse is pseudo-randomly selected to have either positive or negative polarity. If the link partner is a powered device it will be in loopback mode and the transmitted pulses will be looped back to the transmitter (i.e. the PSE). The PSE, at each time unit regardless of whether or not a pulse was transmitted, opens a search window in which it listens to the RX line for the appropriate expected behavior. If a pulse was transmitted, the PSE expects to see a pulse looped back. Similarly, if no pulse was transmitted, the PSE does not expect to receive a signal during the search window. If the expected behavior is observed, a match counter is incremented, otherwise a mismatch counter is incremented. If a sufficient number of matches are received, the PSE concludes that a powered device is present on the network.

摘要翻译：一种用于通过网络检测有源设备的存在的新颖机制。生成唯一的无限伪随机脉冲序列，并通过网络传输到连接到电缆另一端的链路伙伴。在每个时间单位，PSE决定是否在那时发送脉冲。因此，产生的脉冲之间具有伪随机脉冲间延迟。此外，每个脉冲被伪随机选择为具有正极性或负极性。如果链路伙伴是供电设备，它将处于环回模式，并且发送的脉冲将被环回到发射机（即PSE）。在每个时间单位的PSE，无论脉冲是否被发送，都会打开一个搜索窗口，在该窗口中它将侦听RX线路以获得适当的预期行为。如果发送脉冲，则PSE预期会看到脉冲循环。类似地，如果没有发送脉冲，则PSE在搜索窗口期间不期望接收信号。如果观察到预期的行为，则匹配计数器递增，否则不匹配计数器增加。如果接收到足够数量的匹配，则PSE得出结论：网络上存在受电设备。

摘要： A novel mechanism for sharing filter taps across a plurality of interference cancellers. Each interference canceller may be directed to impairment, such as Ethernet impairments, including Ethernet 1000Base-T impairments. Various interference impairments include echo cancellation, NEXT cancellation and/or other interference detection or cancellation, etc. The hardware requirements of the interference impairment cancellers are reduced by sharing filter taps among the cancellers. In a first embodiment, the taps from a unified filter tap bank are shared across all the interference impairment cancellers for all four channels and over all ports. In a second embodiment, a portion of the taps of each filter are shared wherein each canceller comprises a fixed filter tap portion and a shared filter tap portion. A tap allocation algorithm assigns taps to those cancellers that need them the most. A canceller configuration is selected that yields maximal interference mitigation and the taps are allocated accordingly.

摘要： A novel mechanism for 1000BASE-T network adapters to detect and resolve connections for cables that are either fully aligned, fully crossed or semi-crossed. The mechanism is applicable to adapters in either master or slave modes, and operates with cables that either have channels A and B aligned with channels C and D crossed or channels A and B crossed and channels C and D aligned. Cables of different configurations can be switched at any time without impacting network operation. In addition, a mechanism for 1000BASE-T adapters to support multiple scrambling methods between the adapter and its link partner is described.
