This object is used, in case the 'indirect' attachment-method of VoP to xDSL lines is implemented, to create a new row, to modify a row, or delete an existing row in this table. In case the 'direct' attachment-method of VoP to xDSL lines is implemented then rows in this table are automatically created and deleted by the embedded system and this object is not implemented/used. When the object is being used, as described above, rows in this table are dynamically created, modified and deleted by the management system. When the object is being used then before a row in this table can be deleted or taken out of service (by setting this object to 'destroy' or 'notInService'), it MUST be first un-referenced from all associated xDSL lines. A row in voSetupTable is said to be not referenced when there is no instance of xdsl2LineTable (VDSL2-LINE-MIB) which refers to the row.
