Abstract: An information processing terminal device includes a state monitoring unit that monitors whether or not there exits an unread e-mail or a missed call, a light order control unit that makes an emitting unit emit a color corresponding to each sender in a given order when the unread e-mail or the missed call is detected, where a light order control unit determines a light order of the colors according to a receiving order of the unread e-mail or an incoming order of the missed call.

Abstract: A collect call control device in a telephone exchange system in which a call signal for the collect call is sent from an international switching center through a central office exchange and a private branch exchange to a called subscriber, the private branch exchange has an attendant's switchboard connected and the attendant's switchboard has an attendant's telephone connected. The collect call control device detects whether the collect call request is indicated in a call signal which is input to the central office exchange from the international switching center and includes information on the collect call request and a called subscriber's telephone number; determines whether to control the collect call to the called subscriber based on the detection; generates an attendant's telephone number based on the determination; and connects the call signal to the attendant's telephone.
