But you can get similar functionality and more from EOAM regardless of

Does EOAM detect errors on a link with very little traffic?
Anyhow, on for instance ASR9k we get this:
Configuration Mode: WAN Mode
SECTION
LOF = 13, LOS = 7, BIP(B1) = 8980
LINE
AIS = 0, RDI = 25, FEBE = 1241369229, BIP(B2) = 43028956
PATH
AIS = 0, RDI = 0, FEBE = 45308, BIP(B3) = 2558
LOP = 0, NEWPTR = 0, PSE = 0, NSE = 0
WIS ALARMS
SER = 13, FELCDP = 0, FEAISP = 30
WLOS = 7, PLCD = 0
LFEBIP = 1241369229, PBEC = 2558
So using this, you get bit error counters (counting all bits, not just
when there is a packet being sent), and you can also see FEBE (Far End Bit
Error), ie you can see both sides from one end.
If there was the possibility of running G.709 FEC on all interfaces as
well, I'd gladly do that. Anything that detects (and corrects) bit errors
on the link is good.
