| 1. A method of transmitting user data over a synchronous digital communication network (SDH), comprising:
structuring the user data into user data units;
packing the user data units in multiplex units;
contiguously concatenating a plurality of multiplex units (VC-4-4c);
transmitting the contiguously concatenated multiplex units in a common transport module (STM-4); and
converting the contiguous concatenation of the multiplex units (VC-4-4c) to a virtual concatenation of multiplex units (VC-4-Nv),
wherein only part of the multiplex units are filled with user data units, and wherein in the conversion, those multiplex units
which are not filled with user data units are omitted.
