<p>PROBLEM TO BE SOLVED: To provide a method, apparatus and system for implementing Physical Media Attachment (PMA) alignment and rapid transition from a link training mode to a data mode for next-generation high-speed Ethernet(R) links including a 100 Gbps Ethernet link.SOLUTION: A first training frame is sent from a first Ethernet interface and a second training frame is returned from a second Ethernet interface. The training frames have a length that is the same as the length of Physical Media Attachment (PMA) frames, and the returned training frames include receiver readiness status indicia identifying a readiness status of a local receiver port, and countdown data. The readiness status indicia and countdown data are employed to facilitate a rapid transition from the link training mode to the data mode.</p> |
