DSL Stats - Errored seconds, how many are acceptable?

I have LEDE Reboot 17.01.1 on a homehub5a and I seem to have a lot of errors and severely errored seconds in my dsl status data.

here's my stats - Is this normal? (apparently my line is a bit noisy due to the poor wires in my area) - Are these stats bad? and if so what should they be and what could be causing them? - thanks in advance
