Abstract:
1. A method for facilitating a transition from a low power mode and a data mode for a high-speed Ethernet link, comprising: in response to signal initiating a transition from the low power mode to the data mode, transmitting ALERT frames from a transmitter port of a first component at a first end of the link to be received at a receiver port of a second component at an opposing end of the link, the ALERT frames having a first length and being transmitted using Physical Media Attachment (PMA) framing logic employing frames having a second length different than the first length; receiving ALERT frames transmitted from a transmitter port of the second component at a receiving port of the first component, the ALERT frames that are received including frame alignment offset data identifying a relative offset between a start of an ALERT frame and a predetermined location in a PMA frame, and countdown data; and employing the frame alignment offset data and the countdown data to facilitate the transition from the low power mode and the data mode.
