Abstract

PURPOSE:To enable main trunk incoming/outgoing call even during the stop of power application, by keeping the main trunk call during call as it is even if the power application is stopped, and connecting a vacant main trunk to any telephone set immediately after the stop of power application. CONSTITUTION:A main device ME is provided with a power application monitor circuit 5, channel monitor circuit 4, memory 3 and backup battery E. When the stop of power application is detected at the circuit 4, the connnection between a telephone set TEL1 during connection and an external line is held with a latching characteristic of a switching means, the connected information is stored in the memory 3, and a switching means to be connected to any telephone set TEL3 is operated to an external line not during connection. During the stop of power application, the connected information stored in the memory 3 is held with the battery E. At the re-start of power application, the telephone set TEL1 during call at the circuit 4 is detected, the connection correspondence between the external line during call and the telephone set TEl1 is discriminated, and the operation of the switching means can be kept.
