A synchronous method for the clock recovery in transport, from a transmitter to a receiver, of constant bit rate (CBR) services over an ATM network comprises the comparison of the square wave (csd) related to the source frequency to the square wave (cnd) related to the network frequency, by using an exclusive OR (EXOR), to get a signal (y) from which the duty cycle is obtained and the transport to the receiver, with the duty cycle of said signal of the information which is necessary and suficient to recover the source clock, when the network one is known.
