Module: VDSL2-LINE-MIB

OID (symbolic): VDSL2-LINE-MIB::xdsl2LConfProfVdsl2CarMask

OID (numeric): 1.3.6.1.2.1.10.251.1.5.1.2.1.4

Node type: OBJECT-TYPE

Type: Xdsl2CarMask

Access: read-create

Description: VDSL2-specific subcarrier mask. This configuration parameter defines the restrictions, additional to the band plan, to determine the set of subcarriers allowed for transmission in both the upstream and downstream directions. The parameter shall describe the not masked subcarriers as one or more frequency bands. Each band is represented by start and stop

subcarrier indices with a subcarrier spacing of 4.3125 kHz. The valid range of subcarrier indices runs from 0 to at least the index of the highest allowed subcarrier in both transmission directions among all profiles enabled by the parameter xdsl2LConfProfProfiles. Up to 32 bands may be specified. Other subcarriers shall be masked.

What is xdsl2LConfProfVdsl2CarMask?

Defines, as up to 32 start/stop subcarrier-index bands (4.3125 kHz spacing), which subcarriers are allowed for transmission on a VDSL2 line beyond the restrictions already imposed by the band plan; anything outside the listed bands gets masked. An operator uses this to further restrict the usable spectrum on a line profile, for example to cap the highest frequency used regardless of which VDSL2 profile is enabled.
