Therefore, each data can be efficiently read.

FIG. 6 is a flow chart showing a control program for executing the simulation.

First, it is assumed that the HELP button 34 (FIG. 3) of any of the button telephone terminals 1-1 to 1-m is operated (for example, the button telephone terminal 1-1). HELP button 34 of the button telephone terminal 1-1
Button information is transferred to the main controller 10 as the first control information via the data channel 11-1. The input control unit 3 of the main controller 10 identifies the first control information from the data channel and outputs it to the main control circuit 4. As a result, the main control circuit 4 accepts the first control information (step S1), and in response thereto, the initial screen table 14 (FIG. 5) of the second storage section 52 (FIG. 4) of the storage circuit 5 is initialized. The screen data is read (step S2). The initial screen data is data for displaying multiple functions.
It is sent to the key telephone terminal 1-1 through the output control unit 6 and the data channel 12-1. The initial screen data is detected by the CPU 25 (FIG. 2), and its content is displayed on the LCD 29. At this time, the LCD 29 displays a plurality of functions for simulation all at once or in order. The function is displayed with a number for function selection. For example, the display content is “Select call 1, hold 2, transfer 3, speed dial 4, conference 5”. Instead of numbers for function selection,
The function selection button 33 may be displayed to be operated.

Now, for example, if the user operates the number button "1" in order to simulate a calling operation,
This is transmitted as second control information from the key telephone terminal 1-1 to the main control unit 10 via the data channel 11-1. As a result, the main control circuit 4 receives the second control information (step S3).

The main control circuit 4 reads the display data pointer 15-1 of the function menu table 15 of FIG. 5 in response to the second control information of the number button "1", and guides / displays the guidance display data by the pointer. It is read from the function display table 16-1. Information / function display table 16
In addition to the guidance display data, -1 stores an operation instruction pointer, so that it is also read out, and the effective button data of the effective operation table 17-1 is registered by the pointer in the register in the main control circuit. (Step S4). At this time, the valid button data is call button data.

The guidance display data read from the guidance / function display table 16-1 is data for guiding the operation of the first button. The guidance display data is notified to the CPU 25 of the key telephone terminal 1-1 via the output control unit 6 and the data channel 12-1. As a result, the content of the guidance display data, for example, "please press the call button" is displayed on the LCD 29. Although there is an end determination step after step S4, it does not end here yet.

When the user presses the call button of the function selection button 33 (FIG. 3) of the key telephone terminal 1-1 by the guide display, the pressed information is transferred to the main control unit 10 again as the second control information. To be done. Main control circuit 4
Receives the second control information via the data channel 11-1 and the input control unit 3 (step S5), and in response thereto, determines whether the second control information is valid button data, and at the same time, It is determined whether the HELP button 34 (FIG. 3) has been pressed (step S6). That is, the main control circuit 4 determines whether the second control information is the same as the second valid button data stored in the register, and HE
The LP button is used to determine whether to end the simulation.

If it is determined in step S6 that the buttons other than the send button and the HELP button are pressed, the main control circuit 4 generates error data and invalidates the pressing of the buttons (step S7).

When it is determined that the HELP button has been pressed, the main control circuit 4 forcibly ends the simulation (step S9).

On the other hand, if it is determined that the call button has been pressed, the main control circuit 4 proceeds to step S8.
In step S8, it is determined whether or not the process has ended. Since the process has not ended yet at this point, the process moves to step S4 again. In step S4, the main control circuit 4 displays the display simulation data and the next button operation from the storage area of the guidance / function display table 16-1 indicated by the guidance / function instruction pointer of the valid operation table 17-1 of the storage circuit 5. The guidance display data for guiding is read. In addition to the guidance display data, the guidance / function display table 16-1 stores an operation instruction pointer, which is also read out, and the valid button data in the valid operation table 17-1 is read by the pointer. It is stored in a register in the main control circuit. The valid button data stored in the register at this time is data of the number button operated next to the call button.

In step S4, the display simulation data read from the guide / function display table 16-1 of the storage circuit 5 is the transmission lamp 33d (FIG. 3) of the button telephone terminal 1-1 and one station line button. The lamp display data for displaying the station line lamp 35a corresponding to. The read display simulation data is detected by the CPU 25 of the button telephone terminal 1-1 via the output control unit 6 and the data channel 12-1, and the CPU 25
Turns on the transmission lamp 33d and the office line lamp 35a.
On the other hand, the guidance display data is also sent to the key telephone terminal 1-1, and when the CPU 25 detects it, the contents of the guidance display data are displayed on the LCD 29. At this time, the displayed content is “Please input the telephone number”. The guidance display and the lamp display are executed after the transmission button is pressed even when the transmission operation is actually performed. The station line lamp does not necessarily have to be turned on when making a call.

The user looks at the guidance display and inputs the telephone number. The telephone number entered at this time may be a single digit.
The simulation does not detect the number of digits in the phone number.
Therefore, when some number button is pressed, it is used as the second control information by the main control circuit 4 of the main controller 10.
Is accepted (step S5). Next, the main control circuit 4
Executes step S6. Here, if it is determined that the number button is pressed by comparison with the content stored in the register (data of the number button), as in the case of the operation of the above-described call button, step S8 is executed, and here, The end is detected and the simulation of transmission ends.
When the process is finished in step 8, the initial screen may be returned to.

The flowchart of FIG. 6 is the same for the simulation of hold, transfer, speed dial, and three-party conference. When the user of the button telephone terminal 1-1 executes the simulation, the simulation of each function will be described below. In addition, an initial screen displaying a plurality of functions is displayed on the LCD 29, and step S2 in FIG.
Has been completed.

1. The display contents of the hold initial screen is "Select call 1, hold 2, transfer 3, speed dial 4, conference 5".

In order to simulate the holding operation, when the user operates the number button "2", this is the second control information from the button telephone terminal 1-1 to the main control unit 10.
To the data channel 11-1. As a result, the main control circuit 4 receives the second control information (step S3), and the next step is executed.

The main control circuit 4 reads the display data pointer 15-2 of the function menu table 15 of FIG. 5 in response to the second control information of the number button "2", and the guide display data of the address indicated by the pointer. And display simulation data are read from the guide / function display table 16-2. Further, the operation instruction pointer is also read from the guidance / function display table 16-2, and the valid button data of the valid operation table 17-2 is stored in the register in the main control circuit by the pointer (step S4). The valid button data is data of the hold button.

The guidance display data read from the guidance / function display table 16-2 is data for guiding the operation of the first button. The guidance display data is notified to the CPU 25 of the key telephone terminal 1-1 via the output control unit 6 and the data channel 12-1. As a result, the content of the guidance display data, for example, "please press the hold button" is displayed on the LCD 29.

Further, the display simulation data read from the guide / function display table 16-2 is data for pseudoly informing that the key telephone device is in the process of acquiring the station line, and is one of the station line lamps. Is lamp display data for displaying. Since the actual hold is performed during the acquisition of the station line, this display is performed assuming the actual hold scene.

When the user presses the hold button of the function selection button 33 (FIG. 3) of the key telephone terminal 1-1 by the guidance display on the LCD 29, the pressed information is again used as the second control information by the main controller 10. Transferred to. The main control circuit 4 receives the second control information via the data channel 11-1 and the input control unit 3 (step S
5) At the same time as determining whether the second control information is valid button data, it is also determined whether the HELP button 34 (FIG. 3) has been pressed (step S6). That is, the main control circuit 4 uses the second control information in which the second control information is stored in the register.
Is the same as the valid button data of, and HELP
The button determines whether to end the simulation.

If it is determined in step S6 that the button other than the hold button and the HELP button has been pressed, the main control circuit 4 generates error data and invalidates the pressing of the button (step S7).

On the other hand, if it is determined that the hold button has been pressed, the main control circuit 4 proceeds to step S8. In step S8, it is determined whether or not the process has ended. Since the process has not yet ended at this point, the process moves to step S4. In step S4, the main control circuit 4 generates display simulation data and tone simulation data from the storage area of the guidance / function display table 16-2 indicated by the guidance / function instruction pointer of the valid operation table 17-2 of the storage circuit 5. The guidance display data for guiding the next button operation is read. In addition to the guidance display data, the guidance / function display table 16-2 stores an operation instruction pointer, so that it is also read out and the valid button data of the valid operation table 17-2 is read by the pointer. It is stored in a register in the main control circuit. At this time, the valid button data is data of a button (local line button) to be operated next to the hold button.

The display simulation data read from the guidance / function display table 16-2 of the storage circuit 5 in step S4 is the hold lamp 3 of the key telephone terminal 1-1.
3c (FIG. 3) is a lamp display data for executing lighting of the station line lamp 35a corresponding to one station line button. The read display simulation data is detected by the CPU 25 of the button telephone terminal 1-1 via the output control unit 6 and the data channel 12-1, and C
The PU 25 turns on the hold lamp 33c and turns on the office line lamp 35.
Flashes a. On the other hand, the main control circuit 4 controls the tone ROM 9 and the communication path switch circuit 7 by the tone simulation data read in step S4 to generate a second tone. The second tone is sent to the voice channel 12-1 via the speech path switch circuit 7. As a result, a second tone is heard from the handset 22 or the speaker 23 of the key telephone terminal 1-1.

On the other hand, the guidance display data is output by the output control unit 6,
When the data is sent to the key telephone terminal 1-1 via the data channel 11-1 and the CPU 25 detects it, L
The contents of the guidance display data are displayed on the CD 29. At this time, the display content is "holding is released by pressing the station line button during lamp display".

The guidance display, the lamp display, and the generation of the second tone are executed by pressing the hold button even when the hold operation is actually performed. However, the sending of the hold tone to the local line is not executed in this simulation.

When the user sees the guidance display and presses the station line button while the lamp is being displayed, the user executes the operation of canceling the hold.
When the station line button in the lamp display is pressed, the second line
The control information is received by the main control circuit 4 of the main controller 10 (step S5). Next, the main control circuit 4 executes step S6. Here, when it is determined that the local line button in the lamp display is pressed by comparing with the contents stored in the register (data of the number buttons) as in the operation of the hold button described above, step S8 is executed. However, since it has not ended here, the process proceeds to step S4. Here, the display simulation data is read from the guidance / function display table 16-2 shown in the valid operation table 17-2. This display simulation data is sent to the key telephone terminal 1-1 on the data channel 1
The station line lamp which is being transmitted through 2-1 and blinking is switched to lighting. Then, the process ends in step S10.

2. Transfer This transfer is performed by the main controller 10 during a call via the central office line.
Another button to connect to is a function to call a telephone terminal and transfer a call.

Initially, the display content of the initial screen is "Call 1,
Please select hold 2, transfer 3, speed dial 4, conference 5 ".

In order to simulate the transfer operation, when the user operates the number button "3", this serves as the second control information from the button telephone terminal 1-1 to the main controller 10.
To the data channel 11-1. As a result, the main control circuit 4 receives the second control information (step S3), and the next step is executed.

The main control circuit 4 reads the display data pointer 15-3 of the function menu table 15 of FIG. 5 in response to the second control information of the number button "3", and the guide display data of the address indicated by the pointer. And display simulation data are read from the guide / function display table 16-3. Further, the operation instruction pointer is also read from the guide / function display table 16-3, and the valid button data of the valid operation table 17-3 is stored in the register in the main control circuit by the pointer (step S4). The valid button data is data of the transfer button of the function selection button.
