Abstract
A user apparatus periodically detects the mount state of any terminal interface card, and transmits, to a center apparatus, configuration information indicative of the configuration of the user apparatus and including the detection result, when responding to a request for delay time measurement. The center apparatus recognizes and manages the configuration of the user apparatus on the basis of the configuration information. When newly mounting or removing of a terminal interface card has been recognized, the center apparatus performs newly setting releasing of a destination identifier corresponding to the mounted or removed terminal interface card, and notifies the user apparatus of the newly set destination identifier. The user apparatus, in turn, manages identification information sent from the center apparatus, in relation to the terminal interface unit corresponding to the information. As a result, exchange, addition or cancel of communication services which the user uses can be performed easily.
