The invention relates to a method to attenuate transients caused in the desynchroniser by justification events in a digital transmission system. The analogue circuit arrangement realizing the method comprises a by-pass input for receiving the three-state signal (BPin), whereby the signal (BPin) represents justification events upwards and/or downwards, filtering means (R8 and C8) for filtering the pulse signal (BPin), and adding means (AMP2) for adding the filtered pulse signal to the output signal of the loop filter (AMP1), whereby the added output signal controls the loop oscillator (VCO).
