Automode cold start forced. This parameter is defined in order to improve testing of the performance of ATUs supporting automode when it is enabled in the MIB. Change the value of this parameter to 'true' indicates a change in loop conditions applied to the devices under test. The ATUs shall reset any historical information used for automode and for shortening G.994.1 handshake and initialization. Automode is the case where multiple operation-modes are enabled through the vdsl2LConfProfXtuTransSysEna object in the line configuration profile being used for the VDSL line, and where the selection of the actual operation-mode depends not only on the common capabilities of both ATUs (as exchanged in G.994.1), but also on achievable data rates under given loop conditions.

The table vdsl2SpectrumProfModeSpecTable extends the VDSL2 line configuration profile by VDSL Mode Specific parameters. A row in this table that has an index of vdsl2LconfProfVdslMode == defMode(1), is called a 'mandatory' row. A row in this table that has an index such that vdsl2LconfProfVdslMode is not equal to defMode(1), is called an 'optional' row. When a row in the vdsl2LineConfProfTable table (the parent row) is created, the SNMP agent will automatically create a 'mandatory' row in this table. When the parent row is deleted, the SNMP agent will automatically delete all associated rows in this table. Any attempt to delete the 'mandatory' row using the vdsl2LConfProfModeSpecRowStatus attribute will be rejected by the SNMP agent. The manager MAY create an 'optional' row in this table using the vdsl2LConfProfModeSpecRowStatus attribute if the parent row exists. The manager MAY delete an 'optional' row in this table using the vdsl2LConfProfModeSpecRowStatus attribute at any time. If the actual transmission mode of a DSL line does not match one of the 'optional' rows in this table, then the line will use the PSD configuration from the 'mandatory' row. The indexes of this table are vdsl2SpectrumProfName and vdsl2SpectrumProfXdslMode.

The table vdsl2SpectrumProfModeSpecTable extends the VDSL2 line configuration profile by VDSL Mode Specific parameters. A row in this table that has an index of vdsl2LconfProfVdslMode == defMode(1), is called a 'mandatory' row. A row in this table that has an index such that vdsl2LconfProfVdslMode is not equal to defMode(1), is called an 'optional' row. When a row in the vdsl2LineConfProfTable table (the parent row) is created, the SNMP agent will automatically create a 'mandatory' row in this table. When the parent row is deleted, the SNMP agent will automatically delete all associated rows in this table. Any attempt to delete the 'mandatory' row using the vdsl2LConfProfModeSpecRowStatus attribute will be rejected by the SNMP agent. The manager MAY create an 'optional' row in this table using the vdsl2LConfProfModeSpecRowStatus attribute if the parent row exists. The manager MAY delete an 'optional' row in this table using the vdsl2LConfProfModeSpecRowStatus attribute at any time. If the actual transmission mode of a DSL line does not match one of the 'optional' rows in this table, then the line will use the PSD configuration from the 'mandatory' row. The indexes of this entry are vdsl2SpectrumProfName and vdsl2SpectrumProfXdslMode.
