Just for the record I am between 2,100 and 2,200 feet from VRAD, I am pretty happy with my stats. however when the power tier was installed a few weeks ago I noticed the first day, line 1 which was syncing at a slightly slower speed than line 2 and showed over 50,000 FEC's in the first few hours and line 2 showed less than 1,000. I thought something may be wrong with that line, so I let it run for the first week and this pattern continued. I decided to switch the pairs around at my DMARC I swapped line 1 to line 2 and factory reset the gateway. I expected the errors to move with the line, but they did not right from the switch, I noticed the higher error rates again on line 1 and not line 2 as was expected.
I had an I&M tech come out and check both lines and they said they were both good. they swapped my pairs around at the Cross box and I changed out all the parts in the DMARC to make sure there was no problem there. from the DMARC I replaced the 6 foot Cat 6 cable running through the wall directly into my NVG589 to eliminate any issues there, same thing high FEC errors on line 1, I swapped them back at the DMARC again to put the weaker line on line back on line 2 again and still the higher FEC's stayed on line 1.
After all this testing and replacing wires and swapping out the gateway with another one and doing factory resets, changing pairs, etc I still see the same error rates on line 1 vs line 2. I was told by someone at AT&T looking at my line traffic, that traffic was fairly evenly split on both pairs so it doesn't appear to be related to the amount of data flowing on that pair, so now I wonder if either the gateway is reporting FEC's that are not really there, or is the gateway itself the cause of the FEC's on line 1? Maybe something wrong in the firmware?
