Section Overhead
In a Synchronous Transport Frame, nine bytes are delegated in the Frame Overhead
area of the frame for monitoring and maintenance of the frame signal across a section
span. The Section Overhead data is updated each time the frame passes through
Section Terminating Equipment. The functions of the Section Overhead include a frame
alignment pattern, a byte giving the order of appearance of this frame in a multiplexed
