Abstract

PURPOSE:To prevent the set and cancel of extension incoming refusal from being forgot with a key telephone set operator in advance by automatically setting and canceling the extension incoming refusal according to a time set in advance with the machine key telephone set operator. CONSTITUTION:A time control part(TCL) 14 periodically retrieves time data in an RAM15 such as the setting time and canceling time of the extension incoming refusal. When there are the time data to coincide with a present time controlled by the TCL14, the extension incoming refusing information of a said key telephone system 3 are informed a CPU12. The CPU12 starts a main control part interruption processing by the information from the TCL14 and in order to execute the set or cancel of the extension incoming refusal of the said key telephone system 3, the status of the key telephone set 3 in the RAM15 is updated to an extension incoming refusing condition or a canceling condition. After that, the CPU12 returns back to a normal main control part main processing. In the main control part main processing, processing control is automatically executed to refuse or cancel an incoming from an extension concerning the key telephone set 3 from a designated time.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an extension call rejection method for a key telephone device,
In particular, the present invention relates to an extension call rejection method for a key telephone device that rejects extension calls at a set time.

[Conventional technology]

Conventionally, the extension call rejection method of this type of key telephone device was
Rejection of extension calls is set or canceled only by pressing the extension rejection button on the button telephone operation panel.

[Problem that the invention seeks to solve]

The extension call rejection method of the conventional key telephone device described above is as follows:
Since extension call rejection is set or canceled only by special operations on the button telephone operation panel by the key telephone operator, for example, if a key telephone operator sets extension call rejection with the intention of indicating his or her "absence," If you forget to operate it at the desired time, you can make a call from another key telephone and cannot indicate the presence of the spring, and the extension call rejection cannot be canceled by the key telephone operator. If you forget the operation, extension call rejection will continue to be set, so there is a drawback that incoming calls from other key telephones will not be accepted at all even if the key telephone operator is not "absent".

[Means for Solving the Problems] The extension call rejection system of the button telephone device of the present invention provides a button telephone comprising a plurality of button telephones and a key telephone main device that accommodates the plurality of button telephones via a line. In the apparatus, the key telephone main device includes a first storage means for storing control setting data specifying a control method and current status data corresponding to each of the plurality of key telephones, and a first storage means for storing current status data for each of the plurality of key telephones. a second storage means for storing time information of an extension call rejection setting time and an extension call rejection release time, which are one of the specifications of the control method, in response to the above, and a case where the extension call rejection setting time is canceled midway; a third storage means for registering a preset PIN number used for the application; a first storage means for detecting a coincident time with the key telephone main unit and sending an interrupt signal; Read control setting data for setting or canceling the extension call rejection and number information of the setting button telephone set by this control setting data, and an area in the first storage means corresponding to the number information of the setting button telephone. a second control means for controlling the setting button telephone to set the extension call rejection setting or release the extension call rejection by storing data of the status of the content call rejection setting or the extension call rejection release according to the content of the control setting data; It has

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a functional diagram showing an embodiment of the present invention, and FIG. 2 is a flowchart showing an example of extension call rejection processing according to the embodiment shown in FIG.

In FIG. 1, the extension call rejection system of the key telephone device of this embodiment is configured by having a main device 1 and a plurality of key telephones 2 and 3 connected to the main device 1 via a line 5. .

The main device 1 includes a ROM 16 that stores programs, a RAM 15 that stores time data, service information, status information, and passwords for each of the plurality of key telephones 2 and 3, and a built-in clock circuit to manage time. A time control unit (hereinafter referred to as TCL) 14 that performs control, a telephone interface unit (hereinafter referred to as INF) 13 that interfaces with a plurality of button telephones 2.3, and the entire main device 1 are sequence controlled by a program built in ROM 13. The main control unit (hereinafter referred to as CPU) 12 is configured to perform the following steps.

Next, the operation of this embodiment will be explained.

First, for example, button telephone 3 in button telephone 2.3.
We will explain the case where you request extension call rejection settings.

The operator of the button telephone 3 presses a specific button (not shown) on the operation panel of the button telephone 3 to input the time data of the extension call rejection information of the extension call rejection setting time and cancellation time at a predetermined time. This extension call rejection information is sent to the CPU 12 via line 5 and INF 13.
sent to.

The CPU 12 stores time data such as the setting time and cancellation time of the extension call rejection in the extension call rejection area in the RAM 15.

Next, the processing procedure for executing the extension call rejection information input into the RAM 15 will be described with reference to FIGS. 1 and 2.

As shown in FIG. 2, the TCL 14 periodically retrieves time data such as the extension call rejection setting time and cancellation time in the RAM 15 through time control unit processing.
14, if there is time data that matches the current time controlled by T.
Upon notification of information from the CL 14, the main control unit enters interrupt processing, and the corresponding button telephone 3 in the RAM 15 is set or canceled to reject extension calls for the corresponding button telephone 3.
After updating the status of the extension call to the extension call rejection state or release state (step 23), the process returns to the normal main control unit main processing.

In the main control section main processing, processing control is automatically performed to reject incoming calls from extensions from a specified time on the key telephone 3 that has been set to reject incoming calls from extensions by the above-mentioned interrupt processing.

Further, regarding cancellation of extension call rejection for the key telephone set 3 to which extension call rejection has been set, similar interrupt processing control automatically cancels the extension call rejection at a designated time.

For example, if the operator of the button telephone 3 wants to cancel the extension call rejection after setting the extension call rejection time, the operator enters a preset password and a code number for canceling the extension call midway. By inputting from the operation board of the button telephone 3 according to a predetermined procedure, the extension call rejection is canceled midway.

〔Effect of the invention〕

As explained above, the present invention automatically sets and cancels extension call rejection according to the time set in advance by the key telephone operator, thereby determining whether or not calls can be made from other key telephones. Since the setting is automatically set according to the time desired by the key telephone operator, it is possible to prevent the key telephone operator from forgetting to set or release extension call rejection.
