This section explains how to perform F-code communication operatio ns. F-code communication is possible with
machines of other manufacturers that also support F-code communicati on.

F-CODE COMMUNICATION

Exchange of confidential documents (confidential communicat ion), retrieval (polling) and distribution (polling memory ) of
information, distribution of information to multiple destinations (relay br oadcast transmission) are possible with other
machines that support F-code communication.
An F-code* is specified in each communication, enabling a hig her level of security.
* F-code is a commun ication function based on the G3 standard of the ITU-T.

HOW F-CODES WORK

A fax that is transmitted with an F-code is received to the memory box in the receiving ma chine specified by the F-code
(sub-address and passcode). If the F-code sent by the transmitting machi ne does not match the F-code in the receiving
machine, reception will not take place.
The products of other manufacturers may use different terms for "sub-address" and "passcode". If you need to contact the
operator of another machine regarding sub-addresses and passcodes, refer to the terms used by the ITU-T in the table below.
PERFORMING F-CODE COMMUNICATION
The ITU-T is a United Nations organization that establishes communications standards. It is a department of the International
Telecommunication Union (ITU), which coordinates global telecommunications networks and services.
