In the case of polling communication, as shown in FIG. 5, first, from the called side, CED (callee identification), NSF (C) (non-standard device identification / RTI code), NSF (S) (non-standard device identification).・ Standard), CSI
(Called terminal identification) and DIS (digital identification signal) are transmitted to the calling side. Next, from the calling side, NSC (C) (polling operation mode setting command / RTI code), NSC
(S) (Polling mode setting command / standard) is transmitted to the called side. Upon receiving this, the called side returns NSS (C) (non-standard function setting / RTI code) and NSS (S) (non-standard function setting / standard) to the calling side, and the TCF
Send (training check) to the calling party. When the caller receiving this message receives the message normally, it receives the CFR.
Returns (receipt preparation confirmation) to the called party. As a result, the called side transmits PIX (image information transmission command) indicating the image information frame and image information to the calling side.

NSS for polling from calling side to called side
When (S) is transmitted, the frame content is configured as shown in FIG. As shown in the left side of the figure, the contents of the conventional polling NSS frame are AF (start field), CF (check field), FCF (facsimile control field), CCITT code, maker code, NSC (polling mode operation setting). order),
It is configured in the order of polling ID and frame information. On the other hand, the frame contents of the polling NSC (S) according to the present invention, as shown on the right side of the figure, uses the conventional contents as they are, and further, the digit number of the personal polling ID and the personal polling ID itself. It will be added. It should be noted that it is possible to set a parameter indicating the new form before the number of digits of the personal polling ID. The parameter may be a predetermined multi-bit symbol. If the called side finds that it is a new form of personal polling ID, it recognizes that the next data of the frame information is the number of digits of the personal polling ID, and then uses it as the personal polling ID from the next data. take in.

The flow of NSC (S) frame creation is as follows:
As shown in FIG. 7, first, frame information below AF is set in a frame (step 202), and the number of digits of the personal polling ID is checked (step 203). Then, the processing ends. If the number is 5 or more, the number of digits of the personal polling ID is set (step 204), and the personal polling ID is set (for the number of digits) (step 205). As described above, in the present invention, the personal ID may be any combination using not only numbers but also letters and symbols, and the number of digits may be four digits or more, and it is possible to create completely freely. Therefore, it is possible to set symbols and numbers that are easy to remember. Furthermore, when used for transmitting a confidential file or a polling file, the protection property is also improved, which is extremely useful.

[0015]

As described above, according to the present invention,
The personal ID used for the confidential file and the polling file can be created not only with numbers but also with a combination of alphabets and symbols and with an arbitrary number of digits, so that an easy-to-remember ID can be used and protection can be improved. Also,
Since a confidential file and a polling file with a conventional ID (4 digits only) can be handled, it is possible to communicate with a conventional device.
