Abstract
A communication system is provided which allows synchronous devices in different synchronous communication networks to have synchronous communications with one another via an asynchronous communication network. In the communication system of the present invention, a master communication device generates a master clock based on a reference clock which is provided by a clock supplier. The master communication device sends a synchronization information frame, which contains information about the generated master clock, to plural slave communication devices via the asynchronous communication network. The slave communication devices each reproduce the master clock from the received synchronization information frame.
