This section explains how to perform F-code communication operations. F-code communication is possible with
machines of other manufacturers that also support F-code communication.
F-CODE COMMUNICATION
Exchange of confidential documents (confidential communication), retrieval (polling) and distribution (polling memory) of
information, and distribution of information to multiple destinations (relay broadcast transmission) are possible with other
machines that support F-code communication.
An F-code* is specified in each communication, enabling a higher level of security.
* F-code is a communication 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 machine specified by the F-code
(sub-address and passcode). If the F-code sent by the transmitting machine 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.
