adsl2LConfProfScMaskDs
Module: ADSL2-LINE-MIB
OID (symbolic): ADSL2-LINE-MIB::adsl2LConfProfScMaskDs
OID (numeric): 1.3.6.1.2.1.10.238.1.5.1.2.1.2
Node type: OBJECT-TYPE
Type: Adsl2ScMaskDs
Access: read-create
Description: Sub-carriers mask. A bitmap of 512 bits that allows masking up to 512 downstream sub-carriers, depending on NSCds. If bit i (0 <= i < NSCds) is set to '1', the respective downstream sub-carrier i is masked, and if set to '0', the respective sub-carrier is unmasked. Note that there should always be unmasked sub-carriers (i.e., the object cannot be all 1's). Also note that if NSCds < 512, all bits i (NSCds < i <= 512) should be set to '1'.
What is adsl2LConfProfScMaskDs?
This OID stores a 512-bit bitmap that masks (disables) specific downstream sub-carriers in ADSL2. Engineers use sub-carrier masking to avoid frequency bands with interference or poor signal quality. For example, setting bit 75 to 1 disables downstream sub-carrier 75 to avoid interference in that frequency range.
