Method for transmitting data signals by means of virtually linked partial signals via synchronous data networks

A method for protected transmission of a data signal via synchronous data networks, the method comprising:

• subdividing the data signal into a plurality of virtually linked partial signals;
• and
• transmitting the virtually linked partial signals via a plurality of data channels, wherein
• at least one data channel more than needed is used for transmitting the data signal, wherein
• the data signal is subdivided into partial signals transported at a lower data rate and transmitted using all data channels, and wherein
• the data signal is subdivided again and allocated to remaining data channels, if there is a problem with a data channel.

A method for protected transmission of a data signal via synchronous data networks, the method comprising:

• subdividing the data signal into a plurality of virtually linked partial signals;
• determining a number of data channels needed for transmitting the virtually linked partial signals based on characteristics of the data signal;
• and
• transmitting the virtually linked partial signals via a plurality of data channels, wherein
• the plurality of data channels exceeds the determined number of data channels by at least one, wherein
• the overall capacity of the virtually linked partial signals is greater than that of the data signal, and wherein
• all data channels are used for transmitting.
