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.
