A telecommunications network arranged in a hierarchical manner establishes synchronism between operation of pulses at different locations within the network, by sensing a predetermined phase deviation between a master pulse train and a locally produced pulse train, correcting the deviation by adjusting the phase of the locally produced pluse train, determining the time between required corrections of the phase of the locally produced pulse train, and adjusting the control voltage of the master oscillator for the locally produced pulse train in response to the time interval between sucessive corrections of the locally produced pulse train.
