Abstract

PURPOSE:To suitably use a telephone set in the case one telephone line is shared for the telephone set and a data terminal equipment by outputting, to the telephone set, a call signal to let the telephone set ring itself in the case of a call from an equipment other than the data terminal equipment. CONSTITUTION:When a detection signal is outputted from a call signal detector 5, a contacting point 1 is closed to close the DC circuit of a telephone line. After a detection signal is outputted from a hook-off detector 6, a voice response device 9 is activated. Upon completion of the voice response, a facsimile equipment 14 starts a prescribed facsimile transmission procedure. If the opposite equipment is decided to be other than a facsimile equipment i.e. a telephone terminal by a controller 13, a call signal is generated by a call signal generator 11 to let the telephone set 3 ring.
