11.3.1 atidoc03.cfg in Dual IP Mode
In Dual IP mode, the Transponder will first attempt to download the proprietary configuration
file atidoc03.cfg through the CPE’s interface from a TFTP server on the CPE network. In many
networks, the TFTP server is blocked or disabled, so the transponder also has provisions to
download this file through the Cable Modem interface from the modem’s provisioning server if
necessary. The filename and TFTP server location may also be specified through special tags
in the DHCP Offer, refer to
Section 13.3.3, Specifying atidoc03.cfg Name and Location via
DHCP Tags for details. Similiar to Single IP mode, any IDH4 proprietary SNMP MIB setting may
be placed in the modem’s DOCSIS configuration file which would eliminate the need for atidoc03.
