    • The invention relates to a method or an arrangement for the clock synchronization of a plurality of distributed modules of an information or communication system, said modules being coupled via a packet-switched network. At least two of said modules are controlled by a local clock generator of the modules using an adjustable frequency, and a clock signal is transmitted via the network in the form of clock signal packets in a synchronous minter with respect to the local clock of the modules. One of said at least two modules takes over the function of a master module, and all remaining said at least two modules, the slave module(s), synchronize the local clock of the modules with the clock of the master module, wherein said slave modules ascertain a measurement for the deviation of the local clock generator of the modules relative to the clock generator of the master module by comparing the clock signal transmitted by the master module with the clock signal of the modules and use said measurement in order to regulate the local clock generator of the modules.
    • 本发明涉及一种用于信息或通信系统的多个分布式模块的时钟同步的方法或装置,所述模块经由分组交换网络耦合。 至少两个所述模块由模块的本地时钟发生器使用可调频率控制,并且时钟信号以时钟信号分组的形式相对于模块的本地时钟以时钟信号分组的形式传输 。 所述至少两个模块中的一个接管主模块的功能,并且所有剩余的至少两个模块,从模块将模块的本地时钟与主模块的时钟同步,其中所述从站 模块通过将主模块发送的时钟信号与模块的时钟信号进行比较,确定模块本地时钟发生器相对于主模块的时钟发生器的偏差的测量,并使用所述测量来调节 本地时钟发生器的模块。
