摘要： An apparatus for operating a low data-rate (LDR) link and legacy switch at a high data-rate (HDR) includes a first block and a second block. The first block receives input signals from the legacy switch and generates identical output signals. The second block receives the identical output signals and generates an HDR signal for communication over the LDR link coupled to an access point. Further, a media access control (MAC) interface communicates data at a first data rate with an Ethernet PHY block including a first-in-first-out (FIFO) module and a buffer. The FIFO receives data from the MAC interface at the first data rate and transmits data at a second data rate. The buffer receives data from the Ethernet port at the second data rate and transmits the received data at the first data rate in response to detection of an end of packet.

摘要： The PCS and FEC layers are combined into a single layer and the number of lanes is set at four lanes. The combination allows removal of many modules as compared to a serial arrangement of a PCS layer and an FEC layer. The reduction in the number of lanes, as compared to 100 Gbps Ethernet, provides a further simplification or cost reduction by further reducing the needed gates of an ASIC to perform the functions. Changing the lanes in the FEC layer necessitates changing the alignment marker structure. In the preferred embodiment a lane zero marker is used as the first alignment marker in each lane to allow rapid sync. A second alignment marker indicating the particular lane follows the first alignment marker.
摘要翻译：将PCS和FEC层组合成单个层，并将车道数设置为四个车道。与PCS层和FEC层的串行布置相比，该组合允许移除许多模块。与100Gbps以太网相比，车道数量的减少通过进一步减少ASIC的所需门来执行功能，进一步简化或降低成本。改变FEC层中的通道需要改变对准标记结构。在优选实施例中，车道零标记用作每个车道中的第一对准标记，以允许快速同步。指示特定车道的第二对准标记遵循第一对准标记。
