Hot line
Ask your system administrator if you require this function.
Delayed hot line
When the handset of the delayed hot-line telephone 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
telephone works as an ordinary telephone.
Note: This function is only available in newer versions of the
telephone exchange.
Direct hot line
The same function as described above, but no delay. Only hot line
calls can be placed from this line. To be used e.g. as alarm phone,
door phone etc.
Alarm extension
An extension can be programmed by system administrator as an
alarm extension. A call to an alarm extension obtains automatic
intrusion if the extension is busy. Up to seven calling parties may be
connected at the same time.
Emergency state
In the event of an emergency the operator can switch the
exchange into emergency state, during which only pre-
programmed extensions are permitted to make calls.
