<p>PURPOSE:To enable using a subaddress properly according to plural uses at an incoming terminal side by providing a subaddress selecting means and an incoming deciding means to decide the propriety of an incoming call. CONSTITUTION:At each terminal side, a mode corresponding to plural subaddresses for incoming calls and using states is inputted to a subaddress selecting means 1, and one or more subaddresses are selected out of the subaddresses for the incoming calls according to the mode. By an incoming deciding means 2, the subaddress received from an outgoing terminal and the subaddress selected by the selecting means 1 are compared, the propriety of the incoming call, namely, at the time of a coincidence, an incoming acceptance is executed, and at the time of a non-coincidence, an incoming rejection is executed. At an incoming terminal, only when the subaddress of an incoming signal is made to coincide to the subaddress for an incoming call to be mode-set, the signal is detected as the incoming signal, and a communication is executed with the transmission terminal. Thus, the incoming call by the subaddress can be accepted or rejected according to the use.</p> |
