  • Transmission method
    Patent number: 8040919
    Abstract: A transmission method in which a first signal frame, carrying a payload in a first part of the signal frame and second information in a second part of the signal frame, is transmitted intact between a signal source and a signal destination by copying the second information into the first part of at least one additional signal frame, transmitting both frames between the signal source and the signal destination and, at the destination, reconstructing the first signal frame by retrieving its original second information from the first part or parts of the additional signal frame or frames and placing the retrieved second information in the second part of the first signal frame. A typical application of the transmission method lies in its use in an SDH transmission system.
