Abstract

PURPOSE:To shorten a pull-in time by constitution the titled system so that a communication equipment of the side where step-out has occurred executes pull-in at the point of time when a code rule violation of a synchronizing signal sent from the other communication equipment has been detected, and secures synchronization. CONSTITUTION:Each communication equipment is provided with a step-out informing means A, a code rule violation generating means B, and a pull-in means C, and in case when step-out has been generated, a step-out notice information is inserted into a synchronizing signal of a prescribed transmission frame and transmitted to the other communication equipment by the step-out informing means A. In case this step- out notice information has been received, the synchronizing signal of the prescribed transmission frame is allowed to generate a code rule violation by the code rule violation generating means B in a period in which this step-out notice information is being received, and transmitted to the other communication equipment. Also, in case the code rule violation has been detected while a step-out notice is being executed, pull-in is executed at the time when the code rule violation has been detected by the pull-in means C. In such a way, the pull-in time can be shortened without causing erroneous synchronization.
