Some error counters are cumulative and some are per hour or other time period.
I have a question: With my browser I go to my router's configuration page and then to the XDSL information and there is a 30 Minute Near End FEC Interleave and a 30 Minute Far End FEC Interleave section. My 30 Minute Far End FEC Interleave is (0), but my 30 Minute Near End FEC Interleave will start obviously at (0, but over a 5-6 hour period will keep going higher sometimes as high as 4000-5000 30 minute errors. My question is, why does the FEC error rate keep increasing over time and why does it not stay at a constant level?
