Method of time aligning the members of a virtual concatenated group in a synchronous transmission system

摘要

The method according to the present invention serves for time aligning members (VC-4) of a virtual concatenated group. The members (VC-4) are transmitted through a synchronous transmission system (3), a time unit is defined for the virtual concatenated group, the virtual concatenated group is associated to an order of distribution of information among the members (VC-4) in same time unit at a transmission side (1). The method comprises the steps to be carried out at a reception side (2) of:
A) receiving information of the members (VC-4) of the virtual concatenated group;
B) storing into memory means the received information; and
C) reading from the memory means the information of the members of the virtual concatenated group corresponding to the same time unit at the transmission side (2) according to the order, after that a period of time has elapsed since the reception of the information of the most delayed member corresponding to the same time unit.
