The receiver outputs the control channel with the bit definitions defined in Transmit and signal names defined in Port Descriptions – MAC+PCS Variant.

If a DME error has occurred during the reception of a particular DME frame, the control channel outputs are not updated but retain the value of the last received good DME frame and are updated when the next good DME frame is received.

Note: While the Training Protocol is supported natively by the subsystem, there is no logic that controls the far-end transmitter adaptation based on analysis of the received signal quality. This is because, extensive testing has shown that to be unnecessary. However, a training interface is provided on the subsystem that allows access to all subsystem registers and to the DRP port on the transceiver. You can employ this interface to implement your own training algorithm for 10GBASE-KR, if required.
