Hot Line
This feature is programmed by your system administrator.
Delayed Hot Line
When the handset of the delayed Hot Line phone is lifted or when
the Line key is pressed, a timer is started. If no digit is pressed
before time out, a call is automatically generated to a specific
extension or external line. If a digit is pressed before time out the
phone works as an ordinary phone.
Direct Hot Line
The same feature as described above, but without a delay. Only
Hot Line calls can be placed from this line. To be used e.g. as
alarm phone, door phone etc.
Emergency mode
In the event of an emergency the operator can set the exchange
into Emergency mode, during which only preprogrammed
extensions are permitted to make calls. If your extension is not
assigned with this category and you try to make a call, you will not
receive a dial tone.
