13.2.3.3.1 Fast Power-On Re-Connect Advantages and Uses

Fast Power-On Re-Connect was designed to facilitate faster reconnect of a connection when one device and/or PHY is power cycled/reset for some reason and comes back online.

This mechanism assumes that the port was previously Beta connected and in the P2:Active state when the device and/or PHY was reset/power cycled. If the connected peer port supports Fast Retrain it will lose symbol synchronization and will go to the P11: Untested state in an attempt to re-establish synchronization. It will attempt to Retrain for a DISCONNECTED_TONE_INTERVAL (42.66 to 48 milliseconds). If device and/or PHY comes back online while the peer is still in the P11:Untested state (sending continuous tones), the Fast Power-On Re-Connect port will transition directly to P11:Untested and start the Training process at maxPortSpeed. This should reduce the total reconnect time from approximately 500 milliseconds to approximately 5 milliseconds.
