Abstract

PURPOSE:To improve the effect of practical use by displaying an extension state of an extension group stored in an automatic exchange main body onto a display dial button. CONSTITUTION:A dial section 110 dials an extension group number, a control section 112 detects the number and sends a dial data to a main body control section 105, which rewrites the content of a designation extension group number storage section 107 for an extension telephone set into a sent extension group number. The content of a number 101 of an extension state storage section 104 is sent to a control section 112 of an extension telephone set 108 together with a display number 102 and the state of an extension state display dial button 109 corresponding to the display number is displayed. Thus, the button 109 representing an idle state is depressed to send a data of a display number to a control section 115 by the control section 112. The extension group designated by the designated extension group number storage section 107 is referenced to reference the extension state storage section 104 based on the number 101 and the display number 102. A busy tone is sent when the telephone set is in use and when idle, dialing is implemented to a registered extension. Thus, the effect is improved.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic private branch exchange equipped with a switching function, which is used within the premises of a business office or the like.

0002

2. Description of the Related Art In recent years, private branch exchanges have become increasingly automated and various functions have been added to them. A conventional private automatic branch exchange will be explained below based on the drawings.

FIG. 4 is a block diagram of a conventional private automatic branch exchange and an extension telephone. In the private automatic branch exchange main body 200, 201 is an extension number storage unit of an extension telephone; 202 is an extension status storage unit that stores the extension status corresponding to the extension number storage unit;
04 is an extension circuit unit that communicates with each extension telephone, and 203 is a control unit that controls them. 205 and 210 are extension telephones, 206 is a dial section, 208 is a handset section, 209 is a communication circuit section that communicates with the private automatic branch exchange main body 200, and 207 is a control section that controls each section of the extension telephone 205.

[0004] Consisting of the above-mentioned components, the operation thereof will be explained below. Information on changes in the state of the extension telephones 205 and 210 (when in use, the handset section 208 is raised; when idle, the handset section 208 is set down); is transmitted from the control unit 207 of each extension telephone to the communication circuit unit 209, the extension circuit unit 204 of the private automatic branch exchange main body 200, and then to the control unit 203.
sent to. Thereby, the control unit 203 searches the extension number storage unit 201 for the number of the corresponding extension, and stores the received status in the corresponding extension status storage unit 202.

On the other hand, when an extension user wishes to make a call to an extension telephone in a certain department, he dials the number of one of the plurality of telephones in the department. The control unit 203 that received the dial stores the number in the extension number storage unit 201.
The extension status storage unit 20 searches from the number of
Check the information in 2. If the status is free, call the extension of that number. If the status is in use, a busy tone is sent to the extension telephone that made the call. The extension user who hears the busy tone makes a call to the next telephone within the department. If the busy tone is heard again, the call is made to the next phone. This operation will be repeated several times until you find a free phone.

[0006]

[Problem to be Solved by the Invention] As mentioned above, in conventional private automatic branch exchanges, if the called party is busy,
You have to change numbers and make repeated calls until you find a free phone, which is a huge waste of time and effort. To solve this problem, if the caller can make a call after knowing the status of the extension telephone in the department, they will not have to repeat the call operation over and over again.

The present invention solves the above conventional problems and provides a private automatic branch exchange that can know the status of the other party's telephone and can make a call to another telephone in the same department if the other party is busy. The purpose is to

[0008]

[Means for Solving the Problems] In order to achieve the above object, the present invention treats a plurality of extension telephones belonging to one department as one extension group, assigns a number to this extension group, and The telephone is provided with an extension number storage section and an extension status storage section for managing telephone numbers and their status in the order of display numbers on the extension telephone, and a designated extension group storage section for storing extension groups that can be specified for each extension telephone. The extension telephone is equipped with an extension status display call button that displays the status of the telephone belonging to the extension group to be called and enables a call to be made based on the status.

[0009]

[Operation] In the above configuration, the present invention specifies an extension group using the dial section from the extension telephone, and displays the extension status of the extension telephone of the designated extension group stored in the private automatic branch exchange main body. Displayed on the call button, the extension telephone user can make a call after knowing which telephones are available in the desired extension group.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A private automatic branch exchange according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a configuration diagram of a private automatic branch exchange main body, an extension telephone, and an extension group in one embodiment of the present invention. 2 and 3 are flowcharts showing the processing of the control section of the private automatic branch exchange main body and the extension telephone according to the present invention, respectively. In the private automatic branch exchange main body 100, 101 is an extension group number indicating the data area of the extension group, 102 is a display number indicating the order in which the status is displayed on the extension telephone, and 103 is the extension telephone number belonging to the extension group and corresponding to the display number. 104 is an extension status storage unit that stores the status of the extension phone corresponding to the displayed number; 106 is an extension circuit unit that communicates data and voice with the extension phone; 107 is each extension phone unit; A designated extension group number storage unit 105 stores the extension group number designated by the designated extension group number when there is a call in that group, and 105 is a control unit that controls each of these units. In the extension telephone 108, reference numeral 109 indicates the status of the telephones in the extension group, and by pressing the button, a call can be made to the corresponding extension telephone. Reference numeral 110 indicates a dial section for specifying the extension group. , 111 is a communication circuit unit that performs data and voice communication with the extension circuit unit 106 of the private automatic branch exchange main body 100;
Reference numeral 113 is a handset section for performing on/off hooking and making a telephone call, and reference numeral 112 is a control section for controlling each of these sections. Reference numeral 114 indicates an extension group, which includes a plurality of extension telephones similar to 108.

Handset section 113 of extension telephone 108
