Abstract
An object of the present invention is to provide a modem () that is capable of suppressing electric power consumption by switching an operation according to a power supply circumstance in an installation environment. The modem () includes a low-voltage power supply terminal () and a high-voltage power supply terminal (). The low-voltage power supply terminal () is not connected to a power supply unit (). When electric power is supplied from the high-voltage power supply terminal (), a first superposition unit () superposes the electric power input from the high-voltage power supply terminal () on a signal to be transferred to a communication path.
