xdsl2LConfProfScMaskDs
Module: VDSL2-LINE-MIB
OID (symbolic): VDSL2-LINE-MIB::xdsl2LConfProfScMaskDs
OID (numeric): 1.3.6.1.2.1.10.251.1.5.1.2.1.2
Node type: OBJECT-TYPE
Type: Xdsl2ScMaskDs
Access: read-create
Description: Subcarrier mask. A bitmap of 4096 bits that allows masking up to 4096 downstream subcarriers. If bit i (0 <= i < NSCds) is set to '1', the respective downstream subcarrier is masked, and if set to '0', the respective subcarrier is unmasked. Note that there should always be unmasked subcarriers (i.e., this object cannot be all 1's). Also note that if NSCds < 4096, all bits i (NSCds < i <= 4096) should be set to '1'.
What is xdsl2LConfProfScMaskDs?
A 4096-bit mask that lets an operator block specific downstream subcarriers from being used at all (bit set to 1 means masked/blocked), commonly used to protect a licensed radio band or avoid a known-noisy frequency on a particular loop; at least one subcarrier must remain unmasked. This is a coarser, permanent version of the RFI-notching mechanism, applied at profile-configuration time rather than dynamically.
