Getting a lot of FEC errors now. Been connected for 25mins so far.
FEC errors are not counted by DLM as 'errors', but they are something to keep an eye on. I have found that FEC error rates can vary massively with no apparent change in line settings. I haven't proven this yet, but I have seen FEC errors improve after a modem reset vs a physical line disconnection.
In any case, there's plenty of time yet, see what DLM does over the next 10 days.
