Glossary
Terminology and Functions
E
Do-not-disturb
The do-not-disturb function offers the option of blocking internal and external calls as well as
blocking group calls on a specific telephone. A caller hears only a busy signal. An internal
subscriber can reach a telephone with call protection in an emergency using a priority call.
The do-not-disturb function has no influence on outbound calls, callbacks, alarm calls,
scheduled calls, wake-up calls or InterCom calls.
Door Functions
A door terminal system connected with the interface FTZ 123 D12-0 (PBX requires extension
module) 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.
E
Exchange Line Transfer
A suitably authorised telephone, for example, the telephone exchange, can transfer the
exchange line access required for an outgoing call to another internal telephone for a short
period of time. This is meaningful, for example, when this telephone is located in a publicly
accessible room and is only occasionally used for external calls by an employee.
F
Firmware
Firmware is the operating software on the telephone or PBX that is stored in the device itself.
The device cannot function without firmware.
