Swisscom was able to fix one issue and identify another issue that I need to fix.
The wires in the control room were either loose or disconnected (my french isn't good enough to understand the exact issue). The tech fixed that and the Internet was immediately working, but not the phone. There is an issue with the dsl/phone adapter that is causing the phone not to work. I'm off to interdiscount in a few minutes to get a replacement.
