<p>PURPOSE:To evade simultaneous cut back in a multiprocessor switching system, etc., by waiting for the cut back of a signal excepting for a signal link, for which a cut back control flag is turned on, until the cut back is finished through the signal link for which the cut back control flag is turned on. CONSTITUTION:A cut back control flag storage area 8 and a cut back control flag turning ON/OFF control means 10 are provided in a message transmitter. When the signal link is restored, with responding to the detection output of a signal link fault generation/restoring detecting means 4, the cut back control flag turning ON/OFF control means 10 turns on the cut back control flag of the cut back control flag storage area 8. Then, the cut back of the signal link excepting for the signal link, for which this cut back control flag is turned on, is waited until the cut back is finished through the signal link for which the cut back control flag is turned on. Thus, in the cut back of >=2 signal links in the plural signal links, the simultaneous cut back can be prevented and the message can be transmitted in a correct order.</p> |
