Description: The table vdsl2SCStatusSegmentTable contains status parameters of VDSL2/ADSL/ADSL2 and ADSL2+ sub-carriers. Several objects in the table refer to NSus and NSds. For G.993.2, the value of NSus and NSds are respectively the indices of the highest supported upstream and downstream subcarriers according to the selected implementation profile. For ADSL, NSus is equal to NSCus-1 and NSds is equal to NSCds-1. The indexes of this table are ifIndex, vdsl2SCStatusDirection, and vdsl2SCStatusSegment. One index of this entry is an interface index where the interface has an ifType of vdsl2(251). The second index of this entry is the transmission direction. The third index identifies the specific segment of the sub-carriers status addressed.
