Hot line

Ask your system administrator if you require this function.
Delayed Hot line
When the handset of the delayed Hot line phone is lifted, a Call
Duration 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.
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 your 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 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.
