Sounds about right! My line is estimated at being 900 m long - reported attenuation of around 26.6 dB.

I'm at 20 dB line attenuation and at 6 dB SNRM target I can sync at 56Mbps / 13Mbps approximately.

It sounds like your line is banded then...

Mine too.

24.8dB attenuation and sync at 14.9 Mbps with 5.9dB SNRM. Openreach say my line is about 1.2km long so it sort of shows that with fibre using the attenuation isn't the best way to estimate line length.
