efmCuPmeLineAtn
Module: EFM-CU-MIB
OID (symbolic): EFM-CU-MIB::efmCuPmeLineAtn
OID (numeric): 1.3.6.1.2.1.167.1.2.3.1.7
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The current Line Attenuation in dB as perceived by the local PME.
The value of 65535 is returned when the PME is Down or Initializing.
If a Clause 45 MDIO Interface is present, then this object maps to the Line Attenuation register.
What is efmCuPmeLineAtn?
This read-only value (in dB) reports the current line attenuation as measured locally on this PME's copper pair, returning 65535 when the link is down or initializing. Rising attenuation over time is a classic sign of a degrading or lengthening copper loop, useful for capacity-planning or fault troubleshooting.
