Module: DOCS-PNM-MIB
OID (symbolic): DOCS-PNM-MIB::docsPnmCmDsOfdmMerMarThrshldOffset
OID (numeric): 1.3.6.1.4.1.4491.2.1.27.1.2.6.1.2
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: This attribute represents the number of dB below the RequiredDsOfdmQamMer value which is likely to cause uncorrectable errors. Measurements of Subcarrier MER that are this number of dB or more below the RequiredDsOfdmQamMer for the Subcarrier for the profile being tested, will cause the CM to increment the count of the 'docsPnmCmDsOfdmMerMarNumSubCarBelowThrshld' attribute.
This value can only be changed while a test is not in progress. An attempt to set this value while the value of 'docsPnmCmDsOfdmMerMarMeasStatus' is 'busy' will return 'inconsistentValue'.
What is docsPnmCmDsOfdmMerMarThrshldOffset?
The number of dB below the RequiredDsOfdmQamMer value, in quarter-dB units, at which a subcarrier's measured MER counts toward docsPnmCmDsOfdmMerMarNumSubCarBelowThrshld. A smaller offset flags more marginal subcarriers as 'below threshold', giving an admin a tunable sensitivity for spotting profile risk.
