xdsl2LineBandStatusLnAtten
Module: VDSL2-LINE-MIB
OID (symbolic): VDSL2-LINE-MIB::xdsl2LineBandStatusLnAtten
OID (numeric): 1.3.6.1.2.1.10.251.1.1.2.1.2
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: Line Attenuation. When referring to a band in the downstream direction, it is the measured difference in the total power transmitted by the xTU-C and the total power received by the xTU-R over all subcarriers of that band during initialization.
When referring to a band in the upstream direction, it is the measured difference in the total power transmitted by the xTU-R and the total power received by the xTU-C over all subcarriers of that band during initialization.
Values range from 0 to 1270 in units of 0.1 dB (physical values are 0 to 127 dB). A special value of 0x7FFFFFFF (2147483647) indicates the line attenuation is out of range to be represented. A special value of 0x7FFFFFFE (2147483646) indicates the line attenuation measurement is unavailable.
What is xdsl2LineBandStatusLnAtten?
Reports line attenuation for one frequency band, measured during initialization as the power difference between what was transmitted and what was received across that band's subcarriers, in units of 0.1 dB (0 to 127 dB); 2147483647 means out of range and 2147483646 means unavailable. An admin uses this per-band breakdown (rather than the whole-line figure) to spot frequency-selective loop problems such as bridged taps.
