PURPOSE:To eliminate the necessity of a complicated system constitution provided with plural base stations, by restoring normal system synchronism by causing a base station and specific suboffice to respectively send a reference burst and suboffice burst after the suboffice makes communication of system synchronizing information with the specific suboffice. CONSTITUTION:A specific suboffice 3 sends a reference burst 5 instead of a suboffice burst 6 when the transmission of the reference burst 5 is in trouble and, after the function of a base station 2 is restored, the base station 2 and specific suboffice 3 respectively send the reference burst 5 and suboffice burst 6 after communication of synchronizing information is made with the suboffice burst 6 sent from the base station 2. Therefore, the other suboffices can maintain frame synchronism even if the reference burst transmission of the base station 2 is in trouble and any fault in system synchronism can be eliminated. |
