Abstract
Systems and methods described herein provide a method for operation, administration and maintenance (OAM) of data message transmission. The method comprises reading a transmit register of a transmitter associate with a first management entity to determine a transmit status of the transmit register. The method further comprises loading a data message into the transmit register when the transmit status of the transmit register indicates availability. The method further comprises embedding the data message as an out-of-band message with physical code sublayer modulation, and transmitting the out-of-band message on the physical code sublayer to a receiver associated with a second management entity. A transmit state machine of the transmitter and a receive state machine of the receiver establish a handshake to allow the out-of-band message to be passed asynchronously.
