US 10,542,170 B2 · Image communication apparatus and method therefor

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.

Dependent claims

An image communication apparatus to communicate with a telephone set, the image communication apparatus comprising:

a processor configured to control the image communication apparatus;
a detector configured to detect off-hook on the telephone set;
a generator configured to generate an intermittent off-hook voltage;
and
a switch configured to switch a connection state between a state in which the telephone set is connected to a communication line and a state in which the telephone set is connected to the generator,
wherein, in a case where it is set that the telephone set does not ring according to reception of an incoming call when the image communication apparatus is in a power-saving state and a condition for a transition of the image communication apparatus to the power-saving state is satisfied, power supply to the processor is restricted, the telephone set is connected to the generator by the switching unit, and the intermittent off-hook voltage generated by the generator is supplied to the detector.
