ABSTRACT:
Methods and apparati are disclosed for providing disciplined clock signals at a plurality of nodes located throughout a network. In the preferred embodiments, a plurality of clocks are ensembled to provide ensemble time base information. A universal clock signal such as from a global positioning satellite (GPS) or Loran receiver is also provided and the ensembled time information is disciplined to the frequency or the phase of the universal clock signal to provide syntonization or synchronization throughout the network.
