adslLoopDiagResultUsQuietLinePsdN
Module: ASKEY-ADSL-MIB
OID (symbolic): ASKEY-ADSL-MIB::adslLoopDiagResultUsQuietLinePsdN
OID (numeric): 1.3.6.1.4.1.3646.1300.2.2.1.4.19
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: This object provides an array of upstream quiet line noise PSD n. The n of subcarrier(i) is Octect(i), i=0~63. To get real value of QLN(f), it is caculated as (-23-n(i)/2). A special value 255 indicates that no measurement could be done for the subcarrier because it is out of the passband or that the noise PSD is out of range to be represented.
What is adslLoopDiagResultUsQuietLinePsdN?
This read-only 64-octet array reports upstream noise per 64 subcarriers. Each byte encodes PSD; 255 indicates out-of-band or unmeasurable. Values inform CPE modulation settings.
