  • ERROR DETECTION FOR DATA FRAMES
    Publication number: 20110188401
    Abstract: A method for detecting data frame mode mismatch errors may include receiving a data frame that includes an overhead byte. It may be determined whether a value associated with the overhead byte indicates that a transmitting device operating mode matches a receiving device operating mode. In an additional implementation, it may be determined whether a value associated with the overhead byte indicates that a transmitting device output port matches a receiving device input port. An alarm may be generated when it is determined that the value associated with the overhead byte indicates that either the transmitting device operating mode does not match the receiving device operating mode or the transmitting device output port does not match the receiving device input port.
