The invention relates to a method for dynamically changing the bit rate or bandwidth of constant bit rate data structures in an Asynchronous Transfer Mode (ATM) communications environment. The method is caracterized in that it includes the steps of: a) defining within said data channel a Change Indicator (CI) indicative of an end user's request for a bit rate change within said data structures; b) continuously transmitting said Change Indicator from the source side to the destination side, along with the data structures on said data channel; c) upon receipt at said destination side of a user's request of a bit rate change, modifying the value of said Change Indicator; d) at said source side, acknowledging the modification of the value of said Change Indicator, whereby the transmission of data structures continues on the data channel with a new constant bit rate .
