ABSTRACT:
A method and apparatus for distributing an accurate time reference to numus locations, such as to the nodes of a digital communications network which can also be used to synchronize the network, which method and apparatus entails the functions of measurement of the local clock's time error, assignment of weighting factors to the paths over which the time reference is distributed through the network, and correction of the time error of the local clock, wherein the first two functions are not affected by the correction of the clock error at any other mode and wherein the time reference distribution system does not contain any closed (reentrant) distribution paths.
