Abstract

PURPOSE:To rationally decide the capacity of a backup battery and at the same time to miniaturize the battery, by fixing both the working range and the working time of an automatic private branch exchange device with the backup battery in consideration of the exchange service. CONSTITUTION:An interruption trunk 7 has an interruption and feeds a talking subscriber the previous announcement information such as ''The direct service is given in some seconds since the service is interrupted at present.''. At the same time, the busy circuit and the interruption circuit are opened and broken with an interlocking action among a central controller 10, a channel controller 9 and others in the lapse of a certain time from the moment of the service interruption which is decided in consideration of the consumption of a backup battery 13 and the extent of the exchange service. At the same time, a night switching device 5 operates to switch a trunk line 6 to the side of a direct telephone set 8, and a new call given from an extension telephone set 1 after the above-mentioned opening and breaking of the busy circuit, etc. is not processed. The same procedure is carried out as the set 1 for the busy circuit between the trunk line and another extension. In such way, the capacity of the battery 13 can be reduced.
