Many thanks for all the hints and knowledge you are sharing. That's exactly why I love open source projects. =0)
@janh : I guess the ubus call dsl metrics should be called when I try to connect. I will try to find some time when I can take down internet here at home for a while.

I will also try another firmware file as suggested by @pythonic.
Using a different firmware also did not bring up the DSL line.

The state went from Handshake to Exception to Idle request ...
Will also try to get VDSL configuration from the ISP.
