Abstract: A facsimile apparatus includes a storage unit, a first detection unit, and a second detection unit. The storage unit stores a parameter based on a connection standard of a telephone-line connected to the facsimile apparatus, and an apparatus direct-current resistance of the facsimile apparatus. The first detection unit detects a first voltage that is a voltage at a line-open time of a telephone line connected to the facsimile apparatus. The second detection unit detects a second voltage that is a voltage at a line-capture time of the telephone line. By using the first voltage, the second voltage, the parameter, and the apparatus direct-current resistance, a voltage to be a threshold for determination of line capture is determined. By using a voltage detected from the telephone line and the voltage to be the threshold determined by the first determination unit, whether the telephone line is captured is determined.

Abstract: There is provided a method for capturing a line after an elapse of a predetermined time, in a case where the line has been disconnected caused by an occurrence of a specific event in which a heavy load signal is input to an input side connecting the line. The control method for controlling a communication apparatus configured to perform a data communication via a line, includes detecting a signal on the line, disconnecting the line based on a level of the detected signal, and capturing the line based on an elapse of a predetermined time after the line has been disconnected.

Abstract: A device which is capable of minimizing the use of resources in devices and safely communicating information such as settings on devices. The device is capable of communicating with another device via a wireless communication network and manages the other device. The device leaves a first wireless communication network to which the device is currently connected. Then, the device wirelessly connects to the other device so as to construct, with the other device that left the first wireless communication network after the device, a second wireless communication network, which is different from the first wireless communication network, by using a setting network ID for use in a setting change mode for changing setting values of the other device. The device sends setting data to the other device, to which the device was wirelessly connected, via the second wireless communication network.
