I'm seeing an awful lot of FEC on my line. I've seen the FEC count go way over 50+ million. I've had a BT engineer here last thursday testing my line and he said it was perfect. So I'm not sure if its interference or what?
In terms of INP and interleaving my line is similar to yours, though your attainables are less than mine. Your FEC counts aren't far off what I get though, although your ES is way higher than mine for a connection that's only been up for more than 3 hours. At best I usually have 2 to 3 ES an hour. I'm not entirely sure if FEC is accurate, mine is also similar, though as far as I'm aware my line is also performing good as well (when tested some months ago after an engineer fixed a HR fault). Interesting.
INP and sync speed are closely related to the 'D' value is I've noted, so I personally just observe what the INP and delay are. Another interesting bit of info for everyone, my INP changed from 3.0 to 3.5 this morning. I wasn't aware DLM had a profile which set 3.5, just seems like an odd level to use. I'd expect something like 3.0, 4.0, 5.0, 6.0. Oh well, the mysteries of DLM
