Door Functions (System Telephone)
If a door terminal system is connected to the PBX's interface you can run the following functions. A call with the door (intercom) can be held from any telephone. During a call to the door, the door can be opened (open door) and a stairwell light controlled by switching a relay (switch on light).
These functions can be performed on the system telephone even without a pending door call.
