HOT LINE
Definition
Immediate hot line
Immediate hot line means that an extension is
programmed so that when the user lifts the handset or
presses the On/Off-key a call will be initiated
automatically to a predetermined party.
Delayed hot line
Delayed hot line means that when someone lifts the
handset or presses the On/Off-key there will be a
programmable delay before the call is sent to the
predetermined party. This gives the user an
opportunity to dial any destination number.
Use
Hot line can be used among other things for:
• Alarm telephones
• Lift telephones
• Taxi telephones
• Hotel foyers
• Entry phones
• Modems
Calls can be initiated both to internal and external
parties.
For external parties the use of a common abbreviated
number is mandatory.
Operation
All telephones
Outgoing calls
An outgoing call is initiated either by lifting the handset
or pressing the On/Off-key.
From a system telephone it is possible to call any
extension by dialling the relevant extension number
directly or by pressing an optional traffic function key.
Incoming calls
An incoming call to the extension is announced and
answered as from a normal extension.
Capacity
Each extension can be programmed for the hot line
function.
The programmable number comprises a maximum of
four digits.
Limitations
In order to access an external number, the
programmed number must be a common abbreviated
number.
An analogue extension telephone programmed for im-
mediate hot-line, cannot be used for other outgoing
calls.
