Abstract

PURPOSE:To process transit of an internal data to output processing smoothly by not releasing a facsimile equipment when an output of an internal data is interrupted and an external call is received and the arrived call is given up before the facsimile equipment transits to the talking state and taking a procedure of outputting the internal data again. CONSTITUTION:When an internal data output processing in a facsimile equipment 10 is interrupted and the arrival of a call to the facsimile equipment 10 is selected, and when the caller gives up the call and the incoming call is lost before the facsimile equipment 10 transits to the communication state, the output of the internal data is started again without releasing the facsimile equipment 10 going to take the reception of the call. Thus, the internal data output by the facsimile equipment 10 is smoothly restarted without useless call ringing.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone switching system that outputs predetermined internal data within the system to an extension facsimile machine.

Here, internal data refers to data that is held and processed independently by the telephone exchange system, such as billing data, setting data, and messages.

[Prior art] Traditionally, facsimile machines connected to extension lines,
If an incoming call from outside is detected while outputting internal data such as billing data, the system stops sending the internal data to the facsimile machine, releases the facsimile machine, and connects to the incoming call. It had become.

If the incoming call stops while calling the facsimile device for this connection, the call to the facsimile device is stopped and released again, and the facsimile device is called again to output internal data, and the facsimile device is When the device responded, it resumed outputting internal data that had been interrupted.

[Problem to be Solved by the Invention] Therefore, in such a case, the ringtone will sound again immediately after it is temporarily interrupted, which may be annoying to the user, or the output of internal data may be delayed accordingly. This was an inconvenience for users who were in a hurry.

Furthermore, for the system creator, since the facsimile machine is released once and then the ring tone is played again, the number of management states increases and the program steps become larger, so it is not a good system.

SUMMARY OF THE INVENTION An object of the present invention is to provide a telephone switching system that can appropriately handle an incoming call while internal data is being output as a facsimile.

[Means for Solving the Problems] The present invention is capable of accommodating a facsimile device in an extension line,
output control means for outputting predetermined internal data in the system to the extension facsimile machine; first detection means for detecting that the incoming call is an incoming call to the extension facsimile machine; The second to detect
In a telephone exchange system having a detection means and an output interruption control means for interrupting the data output operation of the facsimile device by the output control means, the output control means causes the facsimile device to output the internal data while the facsimile device is outputting the internal data.
When the first detection means detects an incoming call to the facsimile machine, the output interruption control means interrupts the output of the internal data and switches to the incoming call to the extension facsimile machine, and the switching control means If the calling party abandons the call and stops receiving the call while switching to an incoming call using The present invention is characterized by comprising an output restart control means for starting output of internal data again without releasing the facsimile machine that was about to be switched.

[Operation] In the present invention, when interrupting internal data output in a facsimile machine and switching to receiving a call to the facsimile machine, the calling party abandons the call before the calling terminal and the facsimile machine change to a communicating state. By doing this, when the incoming call stops, the facsimile machine starts outputting internal data again without releasing the facsimile machine that was trying to switch to the incoming call, so the facsimile machine's internal data output can be performed without unnecessary ringtones. can be restarted, and internal data can be output efficiently.

[Embodiment] FIG. 1 is a circuit diagram showing the configuration of an embodiment of the present invention.

Furthermore, FIG. 3 shows an example of internal data output according to this embodiment, where (a) is the output when the process ends normally, and (b) is when the process is interrupted due to an incoming call to the facsimile machine that is outputting the internal data. This is the output when

First, the processing during normal processing will be explained.

When an internal data output request occurs (S2) while the facsimile device 10 is in the standby state (s i), the extension facsimile device 10 set for internal data output
(S3), and if a response is detected here (S4)
, connect the communication path between the internal data output facsimile device 10 and the FAX data output interface 8 S5
), issues an internal data output start command to the FAX data output interface 8 (S6), thereby causing internal data to be output (S7).

When the output of the internal data is completed (S13), the internal data output completion message "-End-" shown in FIG. 3(a) will be outputted.S14), FAX
The data output interface 8 is instructed to end the output of internal data (S15), and the output of the internal data is ended (S16).

In this state, when on-hook of the facsimile machine M10 is detected (S29), the communication path connected in S5 is disconnected (S30), and the system returns to the standby state (Sl).

The above is normal internal data output processing.

Further, if an incoming call from an outside line to the facsimile machine 10 is detected (58) while the internal data is being output (S7), the third

10), Transition to suspended state (S11),
In this state, the carrier continues to be output from the extension line and the output of internal data is stopped, thereby maintaining the state in which the output of internal data is interrupted without opening one line.

When on-hook of the facsimile machine 10 is detected in this state (S17), the facsimile machine 10 is called again (S18), and when the facsimile machine 10 responds (S22), the communication path with the caller's facsimile machine is established. 523), responds to the incoming call, and transitions to an internal data outputting communication state (S24).

When on-hook of the facsimile device 10 is detected (326), the communication path is disconnected (527), and the process returns to S3 to call the internal data output facsimile device 10 again and start outputting the internal data from the beginning again.

Further, in the suspended state (S11), if the incoming call is abandoned (S20) before on-hook of the facsimile machine 10 is detected, the on-hook of the facsimile machine 10 is waited, and when this on-hook is detected ( S2
