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.

Data communication

Your telephone can be used together with a PC as an integrated voice and data terminal. Contact your system administrator if you require this function.
