[Means for Solving the Problems] The present invention uses the incoming call mode of the outside line by driving the outside line lamp of the extension phone and causing the extension phone to display a display based on the incoming call mode corresponding to the outside line lamp. It is made so that people can know it.

[0005]

[Embodiment] Fig. 1 is a block diagram showing the configuration of a key telephone system embodying the present invention, in which 1 is a main unit having a switching function, 2 is a dedicated telephone (extension telephone), and 3 is a public network or private branch exchange. This is an external line consisting of an internal line. 4 is a CPU (central processing unit) that controls each part, 5 is CPU4
A ROM (read only memory) 6 stores various information including the incoming call mode set for each outside line and the status of each outside line, and a RAM (6) that stores a work area for calculations by the CPU 4. random access memory). 7 is a communication path unit that controls call exchange, 8 is an external line I/F (interface), and 9 is an extension i
/F, 10 is a voice response circuit that implements voice response, which is one of the outside line call reception modes.

[0006] Below, 11 and 12 are the constituent elements of the dedicated telephone 2, and 11 is a C that controls each part of the dedicated telephone 2.
PU, 12 is RO where the program of CPU 11 is stored
M, 13 stores various information of the CPU 11 and serves as a CPU
This is a RAM that provides a work area for the calculation of U11. 14 is an I/F unit for communicating with the main device 1;
9 is a keyboard, 20 is an outside line button, 21 is an outside line LED (light emitting diode) that displays the status of outside calls, such as making and receiving calls, and 22 is an outside line LED (light emitting diode) that displays various operations from the dedicated telephone, as well as when the dedicated telephone is idle. This is a liquid crystal display that performs a call receiving mode for outside lines set to a call receiving mode other than the normal call receiving mode.

The operation of this embodiment will be explained below according to the flowchart shown in FIG. In this embodiment, the number of external lines accommodated is n, and the CPU 11 and I/F unit 14 of the dedicated telephone determine whether the dedicated telephone 2 having the liquid crystal display 22 is in an idle state.
, the CPU 4 of the main device determines via the extension i/F9 (
S301). If the device is not in the idle state, the step S301 is repeated until the device is in the idle state. In the case of an idle state, i=0 (S302), then it is determined whether i=n (S303), and if i=n, the process ends there. If i≠n, i is incremented to i=i+1 (S304). Then, the CPU 4 determines whether the receiving mode of the external line i is the normal receiving mode by reading the setting data of the receiving mode of the external line in the RAM 6 (S3
05), if the outside line i is set to the normal incoming call mode, the process returns to S303. On the other hand, if an incoming call mode other than the normal incoming call mode is set, the CPU 4 lights up the outside line LED corresponding to outside line i, and displays the incoming call mode (voice response mode, transfer mode, etc.) for outside line i on the liquid crystal display. 22 via the extension i/F9 and the CPU 11 (S306), and the process returns to S303.

[0008] In this embodiment, when multiple outside lines are set to a call receiving mode other than the normal call receiving mode, the CPU
4 causes the outside line LEDs of the plurality of outside lines to blink, and causes the liquid crystal indicator 22 to display the incoming call mode of the outside line with the lowest outside line number (i).

[0009] In another embodiment, in such a case, the CP
U4 lights up the outside line LED 21 corresponding to one outside line to which a call receiving mode other than the normal call receiving mode is set, and causes the liquid crystal display 22 to display the call receiving mode of that outside line. Then, the external line LED 2 corresponding to the other external line
1 is lit and the incoming call mode of that outside line is displayed. For example, if external lines "2" and "4" are set to voice response mode and forwarding mode, respectively,
After turning on the outside line LED for ``4'', turning off the other outside line LEDs, and displaying the LCD for 1 second, the outside line ``4'' turns on.
” lights up the outside line LED, turns off the other outside line LEDs, displays the Tensou LCD for 1 second, and repeats this operation.

[0010]Also, the normal incoming call mode may be displayed as ``Ready''.

If an incoming call is received on the outside line while the incoming call mode is being displayed, the LED corresponding to that outside line is displayed as an incoming call (flashing), and the outside line mode display on the liquid crystal display 22 is interrupted.

As explained above, by displaying on the liquid crystal display an indication that the incoming call mode is set for an external line that is set to an incoming call mode other than the normal incoming call mode, you can see at a glance which one If you know which incoming mode the external line is in, and forget to return the external line to normal incoming mode after setting it to an incoming mode other than normal incoming mode, you can use the display on the LCD to discover the forgetting, or This has the great effect of preventing forgetting to put it back and contributing to the effective use of outside lines.

[0013] In yet another embodiment of the present invention, a dedicated telephone assigned to a master telephone that is permitted to perform system settings for the button telephone device is set to a receiving mode other than the normal receiving mode. When the outside line is not in use, the outside line LED of the relevant outside line button is lit in red. The outside line LED is a two-color LED of red and green, and in a dedicated telephone used to make an outside line or during a call, the corresponding outside line LED lights up in green, and in other dedicated telephones, the relevant outside line LED lights up in red. In addition, if an outside line is put on hold, the outside line LED on the dedicated telephone that made the hold
blinks green in the first cycle, and causes the outside line LED of the other dedicated telephone to blink red in the first cycle. When an incoming call is received on an outside line set to the normal incoming call mode, the outside line LEDs of all dedicated telephones are made to blink red in a second cycle. On the other hand, the display on the liquid crystal display 22 is performed in the same manner as in the above embodiment.

[0014] Therefore, if an outside line set to a call receiving mode other than the normal call receiving mode is not in use, the corresponding outside line LED of the dedicated telephone assigned to the master telephone
The LEDs on the other dedicated telephones are turned off, indicating that the external line is set to a call receiving mode other than the normal call receiving mode.

In this way, in addition to the liquid crystal display, the outside line L
By displaying this on the ED, it becomes clearer which external line is set to a call receiving mode other than the normal call receiving mode. Also, if you can display which external line is set to a receiving mode other than the normal receiving mode on the external line LED, you can simply display which receiving mode is set on the LCD display. This has the effect of reducing the display load on the .

Furthermore, the method of displaying the outside line LED is not limited to the above-mentioned method, but may alternately light up green and red.

[0017]

Effects of the Invention As explained above, by driving the outside line lamp of an extension telephone and causing the extension telephone to display a display based on the incoming call mode corresponding to the outside line lamp, it is possible to switch to an incoming call mode other than the normal incoming call mode. If you forget to return the set external line to normal call receiving mode, the LCD display will help you discover that you forgot to return it, or prevent such forgetting to occur, contributing to the effective use of the external line. be able to.
