Current/Last PME link Fault Status. This is a bitmap of possible conditions. The various bit positions are: lossOfFraming - Loss of Framing for 10P or Loss of Sync word for 2B PMD or Loss of 64/65-octet framing. snrMgnDefect - SNR margin dropped below the threshold. lineAtnDefect - Line Attenuation exceeds the threshold. deviceFault - Indicates a vendor-dependent diagnostic or self-test fault has been detected. configInitFailure - Configuration initialization failure, due to inability of the PME link to support the configuration profile, requested during initialization. protocolInitFailure - Protocol initialization failure, due to an incompatible protocol used by the peer PME during init (that could happen if a peer PMD is a regular G.SDHSL/VDSL modem instead of a 2BASE-TL/10PASS-TS PME). This object is intended to supplement ifOperStatus in IF-MIB. This object holds information about the last fault. efmCuPmeFltStatus is cleared by the device restart. In addition, lossOfFraming, configInitFailure, and protocolInitFailure are cleared by PME init; deviceFault is cleared by successful diagnostics/test; snrMgnDefect and lineAtnDefect are cleared by SNR margin and Line attenuation, respectively, returning to norm and by PME init. This object partially maps to the Clause 30 attribute aPMEStatus. If a Clause 45 MDIO Interface to the PME is present, then this object consolidates information from various PMA/PMD registers, namely: Fault bit in PMA/PMD status 1 register, 10P/2B PMA/PMD link loss register, 10P outgoing indicator bits status register, 10P incoming indicator bits status register, 2B state defects register.
