xdsl2SCStatusQlnScGroupSize
Module: VDSL2-LINE-MIB
OID (symbolic): VDSL2-LINE-MIB::xdsl2SCStatusQlnScGroupSize
OID (numeric): 1.3.6.1.2.1.10.251.1.2.3.1.7
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: Number of subcarriers per group used to report the Quiet Line Noise values for the respective transmission direction. The valid values are 1, 2, 4, and 8. For ADSL, this parameter is equal to 1, and for VDSL2, it is equal to the size of a subcarrier group used to compute these parameters.
What is xdsl2SCStatusQlnScGroupSize?
Reports how many adjacent subcarriers are grouped together (1, 2, 4, or 8) when reporting Quiet Line Noise values for this line; ADSL always groups by 1, VDSL2 uses the group size computed for that line's profile. An admin needs this group size to correctly interpret which frequency range each reported QLN value actually covers.
