<p>When a network device, such as an ADSL modem to be connected to a communication network through an ADSL line facility, is physically connected to a port of a line facility, it is checked whether or not this connection is the first connection (or access). If this connection is the first connection, a first-time flag is affixed to data. This data is notified to the line facility, whereby the network device requests initialization setups from a management side.</p> |
