xdsl2SCStatusSnrScGroupSize
Module: VDSL2-LINE-MIB
OID (symbolic): VDSL2-LINE-MIB::xdsl2SCStatusSnrScGroupSize
OID (numeric): 1.3.6.1.2.1.10.251.1.2.3.1.9
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: Number of subcarriers per group used to report the SNR values on 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 xdsl2SCStatusSnrScGroupSize?
Reports how many adjacent subcarriers are grouped together (1, 2, 4, or 8) when reporting SNR values for this line's transmission direction; ADSL always groups by 1, VDSL2 uses the group size from that line's profile. An admin needs this to map each reported SNR reading back to the correct band of subcarrier frequencies.
