Abstract

PURPOSE:To perform exchange processing successively preceding to switching by setting a status relating to each line connection on both current and preliminary channel devices in a current processor and making a preliminary procesor read the setting status from the preliminary channel device when a trouble occurs. CONSTITUTION:Normally, a current processr 11 sets up the status relating each line connection on both current and preliminarily channel devices 9, 10 and a switching device 8 selects the current channel device 9 to control each transmission line 6. At the time of trouble, the switching device 8 changes the connection to the line 6 and the preliminary channel device 10 and a preliminary processor 12 reads out the setting status from the preliminary channel device 10, performing exchange processing successively preceding to switching.
