Thanks for the suggestions. So the link to the DSL checker is for ADSL only as far as I can tell. And yes the profile is higher via the Swisscom checker. And there has already been a case filed with Swisscom due to the dial tone outage, which they fixed (and that is when the line quality significantly improved in terms of dB margin and attenuation). I guess I have no choice but to wait until the next automated test to be performed. Anyway, thanks for the suggestions.
