3-30 Communicating Using F-Codes (F-Code Based Communication) F-Code Based communication refers to communication in which data is sent and received with sub-addresses and passwords attached in conformance with the ITU-T (International Telecommunication Union) recommendations. F-Codes make it possible to communicate with thirdparty F-code-compliant machines using modes that were previously only available between our own machines. These modes include confidential communication and relay broadcast transmission. This fax uses an F-Code Box to transmit documents to, and receive documents from, another party's fax during an F-Code Based Communication. In this case, in order to designate the F-Code Box and password, special codes are used (in this fax they are called the 'subaddress' and 'F-Code password', respectively). In this way, this fax is able to perform F-Code Based Confidential Communications, as well as carry out and Relay Broadcasting, with facsimiles made by other manufacturers and, naturally, with our own models that have F-Code Based Communication capabilities. Note In order to perform an F-Code Based Communication, the other party's fax must have F-Code Based capabilities specific to the communication you are attempting. F-Code Based Communication can be used in combination with the other various types of fax communication available in this fax. In addition, if you register, in advance, the appropriate subaddress and F-Code password under a speed-dial key, you will not need to enter that information during the actual transmission or reception procedure. Refer to the procedures for each type of fax communication and for the related registration procedures for more detailed information. What F-Codes are used in this fax? In this fax there are two codes used for F-Code Based Communication: a 'subaddress' and an F-Code password. Subaddress This code must be entered by the transmitting party during an F-Code Based Confidential Transmission and F-Code Based Relay Broadcast Transmission. The subaddress is used to designate the desired box (equal to the F-Code Confidential Box or the F-Code Relay Box, as appropriate, in this fax) that is registered in the other party's fax. The acceptable length of the subaddress differs depending on model and maker of the fax machine and, if the entered numbers do not match within the parameters of the fax machine that has the shortest acceptable length, F-Code Based Communication will not be successful. Consult with the other party and compare the parameters of both faxes before actually attempting an F-Code Based Communication. In this fax, the subaddress can be up to 20 digits in length and can include any combination of the numerals 0 - 9 and the symbols * and #. When attempting an F-Code Based Confidential Communication or an F-Code Based Relay Broadcast Transmission with another fax of this same model, the last 4 digits of the subaddress that you enter must match the 4-digit subaddress that the other party has registered in their fax.
