ABSTRACT:
The invention relates to a transmission system comprising at least a transmission device for exchanging transport modules in signals of a synchronous multiplex hierarchy which signals have a frame structure of columns and rows. The transmission device (5) comprises at least an adapter circuit (5) and a switching network (5). The adapter circuit (5) is provided to delay at least a higher-order transport module up to a given position in the adapted frame structured signal. The switching network comprises at least a time stage provided to write and identify column by column the bytes to be stored of an adapted frame structured signal and to read out the bytes identified column by column in a given order to form at least an outgoing frame structured signal.
