adslPortMonitorResultDsQuietLinePsdN
Module: ASKEY-ADSL-MIB
OID (symbolic): ASKEY-ADSL-MIB::adslPortMonitorResultDsQuietLinePsdN
OID (numeric): 1.3.6.1.4.1.3646.1300.2.2.1.14.7
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: This object provides an array of downstream quiet line noise PSD n. The n of subcarrier(i) is Octect(i), i=0~511. 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 adslPortMonitorResultDsQuietLinePsdN?
This read-only 512-octet array reports downstream noise per 512 tones measured during monitoring. Each byte encodes noise level; 255 indicates unmeasurable. Values optimize bit loading.
