Abstract: A device includes a facsimile circuit, a voltage detector, an open-circuit voltage detector, and a telephone status monitoring unit. If a first voltage difference is less than a predetermined voltage difference, the monitoring unit judges that the public line is released if a second voltage difference is less than the predetermined difference, and that the public line is closed if the second difference is not less than the predetermined difference. If, when the facsimile circuit has released the public line, the first difference is not less than the predetermined difference, the monitoring unit judges that the public line is released if the second difference is less than the predetermined difference or if the detected line voltage equals the open-circuit voltage, and that the public line is closed if the second difference is not less than the predetermined difference and if the detected line voltage is different from the open-circuit voltage.

Abstract: In a communication apparatus has a line control unit that controls connection with a communication line network, a communication unit transmits/receives data through the communication line network. A detection circuit detects one of a line voltage value and a line current value when the communication apparatus is connected to the line network.

An adjusting unit adjusts the line voltage value and the line current value so as to satisfy the predetermined standard based on one of the voltage-current characteristic curves stored in the memory unit. A selecting unit selects another voltage-current characteristic curve different from the one of the voltage-current characteristic curves from among the multiple voltage-current characteristic curves stored in the memory unit.
