EOAM are sent periodically regardless of traffic levels. So it'll detect
erroring regardless of traffic levels. However, it'll take longer to detect
it, the smaller it is. While in WAN PHY you'll detect it comparatively
fast.
But EOAM is more tunable, you can define what is too much errors, you can
tune rates, it can informatively give you how the frames are being errored.
In WAN PHY you're using standard defined limit of when to signal REI, some
people might want to signal REI on smaller error rates.
In JNPR the counters look like this:

BIP-B1 3 16
SEF 0 0 OK
LOS 1 1 OK
LOF 0 0 OK
ES-S 4
SES-S 1
SEFS-S 0
