Pseudo CI signal 12 6, when there via the communication line 130 is an incoming call CI signal from the partner apparatus, in order to sound the telephone 128 in a state of being disconnected from the communication line 130, to telephone 128 It is a signal sent. The pseudo CI transmission circuit 116 transmits a pseudo CI signal 126 to the telephone 128 in response to a transmission instruction by the pseudo CI drive signal 115 from the SOC 101. The PSTN 210 is a public line network, and the partner FAX 220 is an image forming apparatus that is a counter machine connected via the PSTN 210. The protection element 230 is a current protection element including a fuse or the like.
