Config TR-064 binding

I need help configuring the TR-064 binding under Openhab 3.3. After the installation of the Lan thing, 8 MAC online channels are currently made available to me from there (4 switches or strings each). I already use 2 of them for mobile phones, of which the switch channels can already be used for presence detection. I identified them via the Fritzbox. How can I find out what the other channels are about?
Another problem arises with the creation of a PHONEBOOK profile, I use the standard phone book.
Most of what I’ve done so far is text based. However, I have a problem understanding the text-based part in the documentation at the bottom. Does anyone of you have a working *.Things or *.items (text-based) that I can use as an example?
