Abstract:
1. A method for changing a data transfer rate used in a part of a communications connection, comprising the steps of: choosing a first processing method from a pre-determined set of processing methods; choosing a first restoration method from a pre-determined set of restoration methods; processing information using a processing method at a first point of the communications connection; transferring the information from the first point to a second point of the communications connection, data transfer rates between the first point and the second point being a first set of data transfer rates; restoring the information using said first restoration method at the second point of the communications connection; changing at least one data transfer rate used between the first point and the second point, the data transfer rates used after changing the at least one data transfer rate between the first point and the second point being a second set of data transfer rates; defining a set of compatible processing methods, each compatible processing method belonging to said pre-determined set of processing methods, having an output information rate that is lower than or equal to a lowest data transfer rate of said first set of data transfer rates and said second set of data transfer rates, and corresponding with a restoration method that belongs to said pre-determined set of restoration methods; selecting, prior to changing the at least one data transfer rate, a second processing method from the set of compatible processing methods; and replacing the first processing method with the second processing method and processing the information using the second processing method.
