card is used then the timeout does not apply when the call forwarding is ISDN to ISDN. This is
because the ISDN Network ensures a correct disconnection of the call.
The external call diversion number is also accessible to incoming callers through the DISA service by
dialling ‘400’ at the answer tone/message, this is useful to allow callers access to an emergency out-
of-hours telephone number when the office is closed.
The external call diversion number also works in conjunction with the door phone to route door
phone calls to the external call diversion telephone number when the office is closed. If door phone
divert is enabled then door phone callers will be diverted to the external divert number. The external
caller can operate the door latch relay by dialling ‘#9’ at any time before the warning tone.
See also: ‘Divert all calls to an external number’ for diverting extension calls on page 11.
Note: this setting will override both Automatic Answering and Courtesy service on an
exchange line.
Note: Door phone diversion can be activated by closing alarm contact 1, if an external
diversion number is programmed and alarm feature is not programmed and used.

Fax Call Handling
If a fax machine is fitted to the system then the extension must be programmed as a fax extension. If
a Fax/Voice Card is fitted then automatic fax detection and transfer to the fax extension can operate.
This can allow a line to be shared with voice calls.
For telephone networks that provide a unique ringing cadence for fax calls the system will transfer
the call to the fax extension automatically before the call has been answered.
As only one fax detector is fitted, it is recommended that fax tone detection is set up on one
exchange line only. This will prevent problems where a fax on two simultaneous incoming calls may
not be detected.
There are three automatic fax-switching modes.
Fax ring detection
The system can examine the ringing pattern on a single exchange line and look for the fax ringing
cadence provided by the network operator, the call will be transferred to the fax extension
