The table hwOntXdslSCStatusSegmentTable contains status parameters of ONT VDSL2 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 ONT VDSL2, NSus is equal to NSCus-1 and NSds is equal to NSCds-1. The indexes of this table are ifIndex, hwOntObjectIndex, hwOntUniPhyType, hwOntXdslPortid, hwOntXdslSCStatusDirection and hwOntXdslSCStatusSegment. The first index of this entry is an interface index where the interface has an ifType of ONT VDSL2. The second index of this entry is ONT ID. The third index of this entry is the physical type of ONT UNI. The fourth index of this entry is the ONT XDSL port ID. The fifth index of this entry is the transmission direction. The sixth index identifiest the specific segment of the sub-carriers status addressed.
