11.3.1 atidoc03.cfg in Dual IP Mode

In Dual IP mode, the Transponder will rst attempt to download the proprietary conguration

le 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 le through the Cable Modem interface from the modem’s provisioning server if

necessary. The lename and TFTP server location may also be specied 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 conguration le which would eliminate the need for atidoc03.
