SDH Frame Structure
The STM-n frame structure is best represented as a rectangle of 9 x 270xN. The 9xN first columns are the frame header and the rest of the frame is the inner structure data (including the data, indication bits, stuff bits, pointers and management).
The STM-n frame is usually transmitted over an optical fiber. The frame is transmitted row by row (first is transmitted the first row then the second and so on). At the beginning of each frame a synchronized bytes A1A2 are transmitted .
The multiplexing method of 4 STM-n streams into a STM-nx4 is an interleaving of the STM-n streams to produce the STM-nx4 stream. The method is shown in the next picture for producing STM-4 from 4 STM 1 streams.
