Abstract

PURPOSE:To allow an operator to recognize an incoming call during a local error by providing a function storing a request destination number in an incoming call as the presence of the incoming call to an event rejecting the incoming call while it is in the state unable of automatic reception (automatic arrival of call). CONSTITUTION:When it is discriminated that no automatic reception is enabled, an I/O controller A 25 is controlled to display a message signifying 'incoming call during local error' from a display device 29, a caller number included in a received SETUP message and an information element of a call destination subaddress are extracted and registered in a prescribed area in a RAM 24. Then the interruption processing is applied to make the operation complete. Thus, even when the operator is not in the equipment installation position, when the operator comes to the installed location, the operator confirms the display of 'incoming call during local error' on the display device 29 and recognizes that the automatic incoming call is disabled.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile device connected to a communication system in which a plurality of terminals are connected to at least one line.

[Prior Art] Conventionally, as this type of communication system, for example, rSD
N (Integrated 5 service Ne
(work) system is known. In this l5DN, one line has two data channels (B channel)
It has three communication channels consisting of one control channel (D channel) and one control channel (D channel), and up to eight terminals can be connected to this line.

Processing such as call connection processing on this line is performed using a control channel (D channel).

[Problems to be Solved by the Invention] However, in the conventional example, when a local error occurs such as when the facsimile machine is out of paper or when the memory is full, incoming calls to the facsimile machine are Even if there is, the data sent cannot be received. Therefore, in such a case, the incoming call addressed to the device itself is rejected.

Even if the operator subsequently intervened, the operator could not find out who had requested the incoming call (the calling party) while the facsimile machine was experiencing a local error, and could not take appropriate action later.

[Means for Solving the Problems] The present invention has been made for the purpose of solving the above-mentioned problems, and includes the following configuration as an embodiment for solving the above-mentioned problems.

That is, a facsimile device connected to a communication system in which a plurality of terminals are connected to at least one line,
an incoming call detection means for detecting an incoming call from a connection line; a determining means for determining whether or not the own device can automatically receive facsimile information sent after the incoming call is detected by the incoming call detecting means; a storage means for detecting and storing the number of the incoming call requesting party when the means determines that automatic reception is not possible; and notifying means for notifying the destination of the stored call request.

[Operation] In the above configuration, in the event that an incoming call is rejected when a local error etc. has occurred in the own device and automatic reception (automatic call reception) is not possible, the incoming call is notified. By providing a function to memorize the call request destination number (caller number, caller subaddress, etc.), the operator can know that a call has been received while the facsimile machine is in a local error state, and You can see where the incoming call is coming from.

[Example 1] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

The following description of this embodiment will be made using a digital facsimile device connected to ISDN as an example.

FIG. 1 is a diagram showing the configuration of an 15DN system to which a digital facsimile device according to an embodiment of the present invention is connected.

In FIG. 1, l is a network termination device (NT), 2 is a bus line connecting one network termination device l and a plurality of terminal devices (4 to 6), 4 is a digital facsimile device of this embodiment, and 5 is a teletex device, and 6 is a digital telephone.

25 is an I10 controller A that controls the keypad 28 and display device 29; 26 is an I10 controller B that controls the scanner 210 and printer 211; 27 is a line control unit; and 28 is an I10 controller for this device. Keypad for performing various operation instructions in six directions, 2
Reference numeral 9 denotes a display device, 210 a scanner for reading a transmitted original, etc., and 211 a printer for printing out received data and the like.

The control of this embodiment having the above configuration will be explained below with reference to FIGS. 3 to 5.

FIG. 3 is a flowchart showing the incoming call processing in this embodiment, FIG. 4 is a flowchart showing the destination number display processing for an incoming call during a local error occurrence in this embodiment, and FIG. 5 is a flowchart showing the call processing on the ISDN line in this embodiment. FIG. 3 is a diagram showing a control sequence.

First, the incoming call processing of this embodiment will be explained with reference to FIGS. 3 and 5. Note that the following explanation will be given for the case where a call request is output from terminal A to terminal B in FIG.

In the digital facsimile apparatus 4 of this embodiment, in the case of an incoming call process, the process shifts to the process shown in FIG.

First, in step S2, a 5ETUP message (reference numeral 51 in FIG. 5) sent from the calling device (terminal A) is received via the line control section 27. In the following step S3, the consistency of the received 5ETUP message is checked, and if consistency is not found, the process proceeds to step S7, instructing the line control unit 27 to execute call disconnection processing, and the process ends. This cutting process is performed, for example, by DI 5C56~ in FIG.
This is done by, for example, executing the RELCOM58 sequence.

On the other hand, if the 5ETUP message is consistent in step S3, the process proceeds to step S4, where the information elements included in the 5ETUP message are recognized, and the 5ETUP message is
Can you receive P-messages (can they be automatically received)?
to decide. If automatic reception is possible, step S
Automatic reception processing is performed at step 9.

In this case, ALERT52 to B-CH communication 5 in FIG.
5, the facsimile data is received and stored in the RAM or printed out from the printer 211. Since this automatic reception process is well known, detailed explanation will be omitted.

After the process is completed, the process proceeds to step S7, instructs the line control unit 27 to execute the disconnection process, and ends the operation. This cutting process is performed, for example, from DISC (56) to REL CO in FIG.
The sequence shown in M (58) is used.

If it is determined in step S4 that automatic reception cannot be performed (when a local error occurs such as when the blink 211 is out of paper or when the received data storage area of the RAM 24 is full memory), the process proceeds to step S5, and the I10 controller A2
5 to cause the display device 29 to display a message meaning "incoming call during local error". Then, in the following step S6, the 5ETU previously received in step S2 is
The information elements of the calling number and the called subaddress contained in the P message are extracted and registered in a predetermined area in the RAM 24. Then, the process advances to step S7, where a cutting process is performed and the operation ends.

Incoming calls from the other party's device are processed as described above, and if automatic reception is enabled, facsimile information from the other party's device is automatically received and printed out from the printer 211 or stored in the RAM 24. . If automatic reception is not possible, a message to that effect is displayed on the display device 29, and the calling number and calling subaddress are stored in the RAM 24.
registered in a predetermined area.

In this way, if the automatic reception is not possible when the call arrives, the display device 29 will display "Call received during local error". Therefore, even if the operator is not at the installation location of this receiving facsimile terminal (terminal B), when he comes to the installation location (returns), the message displayed on the display device 29 will be displayed. You can confirm that the call could not be automatically received by checking the "Call received during local error" display.

Next, the process to be performed when the operator recognizes that automatic reception was not possible will be described below with reference to FIG.

In this case, check the display for "Incoming call with local error" and check the calling source and take some action for this "Incoming call with local error", or take no action at all. You will have to decide whether or not to do it. If no processing is to be performed, press rCL on the keypad 28.
To process, press the "R (Clear)" key.
Enter the "Display" key.

For this reason, after executing the disconnection process in step S7 described above, the process proceeds to step SIO, and the human power applied to the keys on the keypad 28 is monitored. If the "display" key is input, the process advances from step S10 to step Sll, where the "calling number" and "destination sub-address" registered in the RAM 24 in step S6 and which could not be automatically received are displayed. Read out.

Then, in the subsequent step S12, the "calling number" and "calling destination subaddress" read out are displayed on the display device 29.

This allows you to know which parties you could not receive automatically. Therefore, the operator can specify the other party based on the "calling number" and contact the specified other party by telephone or the like to have the desired facsimile data retransmitted.

In this case, along with the display from the display device 29,
Alternatively, the registration data may be printed out from the printer 211 instead of being displayed and controlled to be notified.

On the other hand, even if automatic reception is not possible, if it is determined that no processing is necessary, the "clear" key on the keypad 28 is input. In this case, the process advances from step S10 to step S13, where the display of "incoming call during local error" displayed on the display device 29 is deactivated, and in the following step S14, the automatic call that was previously registered in the RAM 24 in step S6 is turned off. Delete the "calling number" and "calling subaddress" that could not be received. Then, the process ends.

In this way, according to this embodiment, even if facsimile data cannot be received from an important party, it is possible to know with certainty that the facsimile data could not be received and the origin of the call. . Then, appropriate measures can be taken from now on.

In addition, even if no processing is required, the display can be cleared and the registered data can be deleted without unnecessary printouts, which has a great effect on resource conservation. can get.

[Other Examples] In the above explanation, the process when there are multiple incoming calls with a local error occurring has not been clearly explained, but in the case where there are multiple incoming calls with a local error occurring, Also, every time there is an incoming call, the process shown in Figure 3 is carried out, and all the "calling number" and "calling subaddress" for the incoming calls during this period are registered in a predetermined area in the RAM 24. It is also possible to output the information as a report according to an operator's instructions.

In addition, in the above explanation, when there is an incoming call with a local error occurring, the display device 29 displays "Incoming call with a local error"; It may be a good way to let them know.

As explained above, when a digital facsimile device, etc., receives a call when it is unable to receive calls automatically due to a local error such as a paper out memory being full, the system will display an incoming call message. At the same time, the "source number" and "source subaddress" can be stored. Therefore, when the operator returns to the equipment,
It is possible to know where the incoming call came from when a local error has occurred, and appropriate measures can be taken, improving operability.

[Effects of the Invention] As explained above, according to the present invention, in the event that an incoming call is rejected when a local error or the like has occurred in the own device and the incoming call cannot be received automatically, the incoming call is rejected. By providing a function that stores the requested destination number (caller number, caller subaddress, etc.) for the incoming call, the operator can confirm that the call was received while the facsimile machine was in a local error state. It is possible to know where the incoming call originated from. Appropriate responses can then be taken.
