How Signals Are Transported by SDH?
The figure below explains exactly the structure. The container is the basic package unit for tributary channels. A special container is provided for each PDH tributary signal and is always significantly larger than the payload to be transported. The remaining capacity is partly used for justification (stuffing) in order to equalize out-timing inaccuracies in the PDH signals.
A Virtual Container is the entity that travels over the network because it is created or disposed closer to a point of termination service. This is formed by containers and path overhead (POH).
The next step towards formation of a complete STM-N signal is the addition of a pointer indicating the start of the POH. The unit formed by the pointer and the virtual container is referred to as the administrative unit (AU-n) or tributary unit (TU-n). Several Tus together form a tributary unit group (TUG-n) that in turn is collected together into a VC. One or more Aus form an administrative unit group (AUG).

Finally the AUG plus the SOH (Section Overhead) form the STM-N.
