Abstract
An image communication apparatus, to communicate with a telephone set, includes a first control unit, a detection unit, a generation unit, and a second control unit. The first control unit controls the image communication apparatus. The detection unit detects an occurrence of a telephone set off-hook state. The generation unit generates a pseudo-CI signal for ringing the telephone set or an intermittent off-hook voltage to be supplied to the detection unit. The telephone set is connected to a communication line or the generation unit. The second control unit controls the generation unit. Where the telephone set is controlled to wait for a call without being allowed to ring in a power-saving state, the telephone set is connected to the generation unit and placed in the power-saving state. In the power-saving state, the second control unit controls the generation unit to supply a generated intermittent off-hook voltage to the detection unit.
