The table xdsl2LineConfProfModeSpecBandUsTable extends xdsl2LineConfProfModeSpecTable with upstream-band-specific parameters for VDSL2, such as upstream power back-off parameters xdsl2LConfProfUpboPsdA and xdsl2LConfProfUpboPsdB (UPBOPSD-pb).

When a parent 'mandatory row' is created in xdsl2LineConfProfModeSpecTable, the SNMP agent will automatically create several 'mandatory' rows in this table -- one for each upstream band: Note: A mandatory row is one where xdsl2LConfProfXdslMode = defMode(1). When the parent row is deleted, the SNMP agent will automatically delete all associated rows in this table. Any attempt to delete a 'mandatory' row using the xdsl2LConfProfModeSpecBandUsRowStatus object will be rejected by the SNMP agent. The manager MAY create a new 'optional' row in this table using the xdsl2LConfProfModeSpecBandUsRowStatus object if the associated parent row exists, and the value of xdsl2LConfProfXdslMode is a G.993.2 value. The manager MAY delete an 'optional' row in this table using the xdsl2LConfProfModeSpecBandUsRowStatus object at any time.

With respect to the xdsl2LConfProfUpboPsdA and xdsl2LConfProfUpboPsdB parameters, for a given upstream band, if an optional row is missing from this table, then that means upstream power back-off is disabled for that upstream band.

Entries in this table MUST be maintained in a persistent manner.
