Abstract

A first data stream for a first data transmission system having a first data rate contains ATM data cells and structural data, which are distributed as spaced apart data in accordance with a specified instruction and are assigned to a section including in each case a plurality of ATM data cells. While retaining its ATM data cell format, the first data stream is converted into a second data stream containing only ATM data cells for a second data transmission system having a second data rate which is higher than the first data rate. The structural data are thereby selected (or picked out) from the first data stream and are input into a marked structural cell having the ATM cell format, for the section. The structural cell is inserted into the second data stream to partially fill an unoccupied section resulting from the differing data rates.
