A feed forward apparatus and method discipline a clock signal by a reference signal in digital telecommunication networks. A synthesizer correction term within the feed forward apparatus and method includes a frequency correction term so that when one frequency correction term is selected in place of another frequency correction term the phase of the clock signal remains free from extraneous frequency or phase variations during the transition between frequency correction terms. Alternatively, the synthesizer correction term includes a phase correction term so that phase coherence between the reference signal and the clock signal results.
