Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a facsimile machine, and more particularly to a technique for switching a dial signal when a private branch exchange is used.
[0002]
[Prior art]
In a public line network, a function for setting pulse dial / push dial as a function of a terminal is usually required. Japanese Patent No. 2823165 shows a technique for making a call by switching the line type (pulse dial / push dial). However, there are countries overseas that do not allow users to switch between pulse dialing and push dialing. This is because the PSTN (public line network) is configured only by push dial.
[0003]
[Problems to be solved by the invention]
By the way, some private branch exchanges have older models that can only set pulse dialing. If the terminal is connected to a private branch exchange that can only set pulse dialing, the user cannot switch dialing settings. The service cost will increase.
[0004]
FIG. 4 is a diagram showing a relationship among a public line network, a private branch exchange, and a terminal. Between the column of circled number 1 terminal and private branch exchange, column circled number 2 shows between private branch exchange and the public network. Considering the problems in the relationship between the public line network, private branch exchange, and terminal based on FIG. 4, when pulse dialing is necessary for the public line network, switching between pulse dial / push dial is open to the user. Even if connected to the private branch exchange, there is no problem ( cases 1 and 3).
[0005]
On the other hand, when connected to the public line network by push dial, if the private branch exchange is compatible with push dial, the call from the private branch exchange has no problem with push dial (case 4). A problem arises when push dialing is used for the public network but only pulse dialing is possible for the private branch exchange (case 2).
[0006]
In the present invention, when the user does not set pulse dial / push dial on the public line network, the user can switch between pulse dial and push dial even when the exchange connected to the private branch exchange supports only pulse dial. An object of the present invention is to provide a facsimile apparatus that can be used.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 is an operation for performing an external line access number input display and switching display between a pulse dial and a push dial in a facsimile apparatus in which the network control means is connected to only one line. display means, when the external access number based on external access number input display is entered, it relates to a facsimile apparatus characterized by comprising a system controller for controlling the operation display unit so as to switch display .
[0011]
The invention of claim 2, wherein, in the facsimile apparatus network control unit is connected to two lines, and external access number input display, and an operation display unit for switching display of pulse dialing push dial outside line access number input The present invention relates to a facsimile apparatus comprising system control means for controlling operation display means to perform switching display when an outside line access number is input based on the display.
[0013]
The invention according to claim 3 is based on the external line access number input display, the operation display means for switching between the pulse dial and the push dial, and the external line access number input display in the facsimile apparatus having two sets of network control means. The present invention also relates to a facsimile apparatus comprising system control means for controlling operation display means to perform switching display when an outside line access number is input.
[0014]
In the present invention, when it is recognized that the private branch exchange is connected, a screen for selecting either the pulse dial or the push dial is displayed on the operation display means. The user sees this screen and selects pulse dialing or push dialing.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram of a facsimile apparatus according to the first embodiment.
This facsimile machine supports only one line. The system control unit 1 performs a control process for each unit and a facsimile transmission control procedure. The system memory 2 stores necessary data and is used as a work area when the system control unit 1 executes a program.
[0016]
The scanner 3 reads a document with a predetermined resolution. The plotter 4 prints images or list reports at a predetermined resolution. The read-only memory 5 has an area for storing programs and various tables. The writable nonvolatile memory 6 stores registration data obtained by parameters necessary for system control and user operations. The network control unit 7 is connected to a public telephone line network and has an automatic transmission function.
[0017]
The G3 FAX modem 8 implements a group 3 facsimile modem function. The image memory 9 stores transmission images and reception images as necessary. The encoding / decoding unit 10 compresses the raw image into a predetermined code or expands the encoded image into the original raw image. The operation display unit 11 performs communication operation, registration operation, and the like, and includes various keys and a display.
[0018]
Next, the operation will be described.
All software control is performed by the system control unit 1. The user places a document on the scanner 3, inputs the dial number of the other party on the operation display unit 11, and presses the start button. The original is scanned from the scanner 3 at a specified line density, and the data is compressed by the encoding / decoding unit 10 and stored in the image memory 9. When the accumulation of all data of the original is completed, the system control unit 1 then instructs a communication control unit (not shown) to start communication. First, a pulse dial / push dial is designated to the network control unit 7 to make a dial call.
[0019]
Here, the writable nonvolatile memory 6 is provided with a soft switch for setting a line to the private branch exchange. The system control unit 1 determines whether the facsimile apparatus is connected to the private branch exchange from the state of the soft switch, and displays the screen on the operation display unit 11. The user designates pulse dial / push dial on the operation display unit 11 while viewing this screen display. The information is stored in the writable nonvolatile memory 6.
[0020]
Thereafter, the protocol is advanced in response to the response of the partner machine, and when the image information phase (phase C) is entered, the image information is read from the image memory 9 and decoded by the encoding / decoding unit 10 and stored in the system memory 2 Once read, the sender information is embedded in the image information, the image information is compressed again by the encoding / decoding unit 10, and the image information is output on the line through the G3 FAX modem 8 and the network control unit 7.
[0021]
FIG. 2 is a block diagram of a facsimile apparatus according to the second embodiment.
If there is only one line, a call cannot be received from the public line network unless the private branch exchange (PABX) has a dial-in function. In order to connect to a PABX that does not have a dial-in function, in the facsimile apparatus of FIG. 2, one is equipped with an NCU 7 that is connected to the PABX and the other is connected to the PSTN. Basically, one of the two lines is connected to the private branch exchange, but both lines may be connected to the public line network.
[0022]
FIG. 3 is a block diagram of a facsimile apparatus according to the third embodiment.
The facsimile apparatus of FIG. 3 uses the network control unit 7-1 and the G3 FAX modem 8-1 as one line, and uses the network control unit 7-2 and the G3 FAX modem 8-2 as the other line. Thus, having a device for two lines can physically support two lines. Further, by alternately reading and sharing the image memory 9 and the encoding / decoding unit 10, two communications can be performed simultaneously. In addition, pulse dial / push dial can be set in both the network control unit 7-1 and the network control unit 7-2.
[0023]
Here, the pulse dial / push dial setting will be described.
The case where the setting should not be displayed is in the following two situations.
