| Description | Desired SNR margin threshold for the 2B/10P PME.
This object configures the SNR margin alarm threshold.
When the current value of SNR margin reaches or exceeds this
threshold, an efmCuPmeSnrMgnCrossing notification MAY be
generated, if enabled by efmCuPmeSnrMgnCrossingEnable.
This object is writable for the CO subtype PMEs
(2BaseTL-O/10PassTS-O). It is read-only for the CPE subtype
(2BaseTL-R/10PassTS-R).
Changing of the SNR margin threshold MUST be performed when
the link is Down. Attempts to change this object MUST be
rejected (in case of SNMP with the error inconsistentValue),
if the link is Up or Initializing.
If a Clause 45 MDIO Interface to the PME is present, then this
object maps to the SNR margin threshold bits in the 2B PMD
line quality thresholds register. |
