Abstract
PURPOSE:To ensure the exchange service in on-line by executing an instruction to both duplicated channel systems so as to decide the normality thereby setting the normal system as an active system. CONSTITUTION:A subscriber circuit 1 and a processor 4 are connected via a 0 system channel 5 and a 1 system channel 6 in the channel system of duplicated constitution. In setting either the 0 system channel system 5 or the 1 system channel system 6 at the leading processing as the active system and the other as the standby system, the instruction of initializing or write is issued to both the systems 5, 6 during leading, whether or not the instruction is executed normally is judged and the normal channel system is set as the active system. Thus, it is not required to set a channel system having a fault potentially as the active system and the exchange service in on-line is guaranteed.
