Door Functions
A door terminal connected with the interface of the PBX enables the following functions. Calls to the door can be made from any telephone (intercom). 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 executed on the system telephone without initiating a door call.
