Abstract
A network connecting section is configured to operate by using operational power and connected to the telephone network to perform transmission and reception of signals with the telephone network. A main power supply is configured to supply a supply target including the network connecting section with the operational power. A network-event detector is configured to detect an electrical change in the telephone network as a network event. A normal-mode setter is configured to set an operational mode to a normal mode when the network-event detector detects the network event in a state where the operational mode is in a stopped mode. The normal mode is the operational mode in which the operational power is supplied from the main power supply to the network connecting section. The stopped mode is the operational mode in which supply of the operational power to the network connecting section is stopped.
