Abstract

PURPOSE:To perform incoming/outgoing for each line by one telephone set by switching and connecting the telephone set to either lines via a facsimile equipment and switching and connecting the telephone set directly to either the lines. CONSTITUTION:In case of using a subscriber line 3 in facsimile communication by connecting the subscriber line 3 to the facsimile equipment 2, the incoming from a dedicated line 4 is detected by an incoming detection circuit 202, and the incoming of the dedicated line 4 is informed from the incoming detection circuit 202 to a CPU 205. The CPU205 judges the fact that the subscriber line 3 is used in the facsimile communication based on the detected output of a DC loop detector 102, and judges the connection of the telephone set 110 to the dedicated line 4 corresponding to the incoming from the dedicated line 4. And the CPU205 turns on relays K32, K37, and K38 to switch relay contacts K32a, K37a, and K38a. As a result, it is possible to receive the incoming from the dedicated line 4 by the telephone set 110.
