Abstract

PURPOSE:To directly connect standard facsimile equipment to the inner line side of a main key telephone system by incorporating the circuit parts of an incoming call signal detecting part, etc., to detect an incoming call signal transmitted in a data line into facsimile equipment. CONSTITUTION:When the detecting output of an incoming call signal detecting part 11 of facsimile equipment 5 is inputted to a counter part 12 and arrives at the specified number of times specified beforehand, a driving current is supplied to a relay 7 and a counting completing signal is sent to a response signal sending circuit 13. The relay 7 and respective switching contacts 7a and 7b constitutes a switching circuit part to switch and connects a calling line 4 from a key telephone system 6 to a facsimile main body part 15. The response signal sending part 13 receives the receiving completion of picture information or the transmitting completing signal of the picture information from the facsimile main body 15 and simultaneously, sends a cutting signal for the calling line 4 through a buffer amplifier 16.
