Abstract

A method is shown for transmitting a digital data message in time slots within fixed length time frames between a sending unit and a receiving unit. The message is transcoded for transmission according to a transcoding function and when the transcoding function is due to be changed, one of the units sends to the other unit a signal indicating at which frame the transcoding will change.
