xdsl2SCStatusLinScGroupSize
Module: VDSL2-LINE-MIB
OID (symbolic): VDSL2-LINE-MIB::xdsl2SCStatusLinScGroupSize
OID (numeric): 1.3.6.1.2.1.10.251.1.2.3.1.3
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: Number of subcarriers per group used to report the H(f) linear representation values for the respective transmission direction. The valid values are 1, 2, 4, and 8. For ADSL, this parameter is equal to one and, for VDSL2, it is equal to the size of a subcarrier group used to compute these parameters. This parameter is only available after a loop diagnostic procedure.
What is xdsl2SCStatusLinScGroupSize?
This object specifies how many adjacent VDSL2 subcarriers are grouped together when reporting the linear channel response (H(f) values) for each transmission direction. The valid group sizes are 1, 2, 4, or 8 subcarriers; in ADSL this is always 1, while in VDSL2 it depends on the channel estimation parameters. Technicians use this value to properly interpret the channel response data after running line diagnostics, as it determines the resolution of frequency-domain analysis available for troubleshooting line quality issues.
