Abstract

The invention relates to a method for synchronizing transmissions at a constant bit rate in ATM networks and circuit arrangements for carrying out the method, in which a time stamp T.sub.S is fed to the ATM cells which have been input on the receiver side, the data is output in a delayed fashion, the actual delay time (T.sub.A -T.sub.S) is compared with a prescribed desired value t.sub.V, and a correcting variable, which adjusts the clock frequency of a time base (14) counter to the error variable, is generated by a controller (13) on the basis of the error variable t.sub.R =t.sub.V -(T.sub.A -T.sub.S).
