Module: ADSL2-LINE-MIB
OID (symbolic): ADSL2-LINE-MIB::adsl2LConfProfRfiBandsDs
OID (numeric): 1.3.6.1.2.1.10.238.1.5.1.2.1.4
Node type: OBJECT-TYPE
Type: Adsl2RfiDs
Access: read-create
Description: The subset of downstream PSD mask breakpoints that shall be used to notch an RFI band. The specific interpolation around these points is defined in G.992.5. It is a bitmap of 512 bits that allows referring to 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 part of a notch filter, and if set to '0', the respective sub-carrier is not part of a notch filter. This information complements the specification provided by adsl2LConfProfPsdMaskDs. Note that if NSCds < 512, all bits i (NSCds<i<512) should be set to '0'.
What is adsl2LConfProfRfiBandsDs?
This OID stores a 512-bit bitmap identifying which downstream sub-carriers participate in RFI (Radio Frequency Interference) notch filtering. Engineers use this to reduce interference from radio transmissions by applying specialized filtering to affected frequencies. For example, setting bits 200-250 to 1 creates a notch filter across that frequency range to suppress radio interference.
