The DSLPipe unit uses the minimal configuration it obtains via DHCP to access the specified TFTP server and a configuration file, which is identified by a filename that matches the unit’s serial number. After downloading the file, the DSLPipe begins using the configuration.

For this feature to work, the network administrator must set up the DHCP and TFTP servers, as described in the next sections. In addition, the DHCP server must be configured to access DNS, so the client can access the specified TFTP server by name.

For details about the DSLTNT requirements, see “Configuring the DSLTNT” on page 17-15.
