Abstract
A synchronization system (D) for equipment of a synchronous transport network comprises, firstly, a first synchronization module (MA) comprising i) a first submodule (SMA) delivering a first intermediate clock signal derived from a first external reference clock signal or an internal reference clock signal, ii) a second submodule (SMA) delivering a first main reference clock signal derived from the first intermediate clock signal or a second intermediate clock signal, and iii) a third submodule (SMA) delivering a first output reference clock signal derived from the first main reference clock signal or a second main reference clock signal, and, secondly, a second synchronization module (MB) comprising i) a first submodule (SMB) delivering the second intermediate clock signal derived from another first external reference clock signal and another internal reference clock signal, ii) a second submodule (SMB) delivering the second main reference clock signal derived from the first or the second intermediate clock signal, and iii) a third submodule (SMB) delivering a second output reference clock signal derived from the first or the second main reference clock signal.
