Hi Anvey88
I guess it would be nice to extend the external line from master box (Before connecting to slave cables) directly to Comfort TEL-IN and from TEL-OUT back to the master socket to feed the slaves according to Hookup Diagram. the slave cables should only be connected to the cable which comes from TEL-OUT.
It would be 2 telephone cables between Comfort panel and master socket.
Also see Quick Installation Guide page 5. It would be different if you have an ADSL modem connected to phone line.
