ABSTRACT:
In a digital signal transmission system for effecting time-division multiplexing/circuit switching transmission of data in the form of packets by means of transmission cable, a method for the synchronization of system timing which permits the establishment of system timing such as the synchronization of frames and blocks is improved.
For this purpose, all of the individual personal stations in the transmission system have their own respective distance codes, and only the master station incorporates the distance code of transmitting personal station in its master packet, and the other personal stations than the master station independently calculate their own timing for sending out packets on the basis of the aforementioned data to establish their own system timing.
