Abstract

The invention relates to a data transmission system for the frame-oriented digital data transmission of a plurality of useful signals embedded in a carrier signal, using time-division multiplex operation, rate matching being undertaken between the useful signals and the carrier signal by means of stuff locations. The data to be stuffed, and the management information for the reassignment are embedded in previously unused 8 bytes in the path layer overhead of the carrier signal superframe, and protected by an HC(6,3,3) code. Clear channel signals can advantageously be transmitted using the system, and the transmission is time-transparent and data-transparent.
