FEC are corrected errors on the line. A large number results from a lot of noise on your line. DSL is very distance sensitive, and the sensitivity increases as the throughput goes up.

Your SNR is marginal. You don't have a ton of uncorrected errors on your line now, but this could be an issue going forward, especially when the weather gets bad in the winter. You may need to reduce the line profile (read: slow things down) to achieve a stable connection.

Note that your current attainable throughput is less than the maximum rate supported by the DSLAM. This may mean that if you can clean things up you can get even more speed, but that would be up to your ISP. It's worrying that your current rate is identical to your max attainable -- 100% occupancy leaves you with nowhere to go in the event of signal degradation.

Alternatively you might attempt to clean up the wiring. Your attenuation doesn't indicate an excessively long loop, so it's probable that either your internal wiring or the drop is sub-par. I don't know how things work over there for this -- in Canada, the phone company is responsible for everything up to the point of demarcation, while the subscriber is responsible for all wiring inside the home. Things might be different where you are though, as it would be subject to local regulations.

If you can, connect your DSL modem directly to the demarc and repeat the test. This will help to narrow down where the source of the trouble is.
