Opener Intercom

Hello, I would like to install a Nuki Opener and our internal intercom is not listed. Which isn’t the problem. My problem are the names that I can not assign.

Assigned terminals have the designation:

L L CFP CFP

I think it’ is a Bus system and I would need the intercom cable and the bus+ cable - but I don’t know which one is the right.

It is a Comelit 2408W/A.

thank you for you help
