Abstract
In a multistation communication network for effecting time-sharing multiplex transmission and reception of digital signals in the form of packets by the use of optical cables, this invention establishes system timing by putting up a flag identifying a master station only in the packet signal issued by a personal station which has acquired priority in system timing, finding front guard time for the individual personal stations by arithmetic processing using the distances from an optical star coupler to the personal stations and the guard time at the position of the optical star coupler, and clocking the front guard time based on the timing of reception of the packet signal from the master station.
