Description

How to provide text information from a PABX

The present invention relates to a private branch exchange, and more particularly, to a method for providing preset character information to a plurality of terminals subscribed to the private branch exchange and having a character display device in a private branch exchange.

Conventionally, a private branch exchange is used in a place such as a general office, and performs a function of connecting a trunk line and a station line by a telephone line (usually called a trunk line) between a trunk line switching facility and a transitional handling section belonging to the trunk line. In the case of a private branch exchange equipped with a CTI matching circuit, there are a public telephone set and a digital key telephone set, and the terminals connected to the public switched telephone network are called collectively referred to as an extension telephone. Computers can also be included. That is, a computer is subscribed to a private branch exchange to perform various operations such as performing data processing. In particular, the digital key telephone is operated by a user to perform various functions for performing a call processing operation of the PABX, and at the same time, a character display device is provided so that various functions are performed, Simple information that is routinely needed is displayed. In addition, information such as the name of the subscriber of the digital key telephone, his / her phone number, etc. is displayed.

However, most of the displayed information is not important to actual users. In addition, when the user does not make a call through the digital key telephone, even the simple information to be displayed is not seen, and therefore, the displayed information is also made of low importance information. Considering the fact that a private branch exchanger is installed in a real company or work space of a private branch exchange and most of the employees have a terminal to which it is subscribed, Or for the convenience of the user, the function of providing the text information in the PBX is not properly implemented.

.

Accordingly, it is an object of the present invention to provide a method for providing character information to a plurality of terminals subscribed to the PBX, the PBX having a character display device.

In addition, a method for setting a character information providing function, such as inputting and storing character information to be provided, is performed through the terminals.

In addition, in a private switchboard having a CTI matching circuit, character information is inputted or stored through a computer connected to the CTI matching circuit, or a function to be provided is implemented.

In order to achieve the above-mentioned objects, the present invention provides a method for receiving a message, comprising the steps of: receiving and storing a predetermined message displayed on a terminal when providing character information from an arbitrary terminal subscribed to a private branch exchange; A step of detecting the terminals on which the character display device subscribed to the private branch exchange is implemented and successively providing the stored predetermined messages to the detected terminals and displaying the provided message on the character display device of the terminals Lee suggests a method for providing character information.

Hereinafter, the present invention will be described in detail.

1 is an example of a system block diagram of a private branch exchange in which the present invention is implemented.

Referring to FIG. 1, the central processing unit 100 processes a predetermined program to control a call switch, and controls various services and operations according to the present invention. A RAM (Random Access Memory) 110 has a program and volatile data processing area, and is composed of a plurality of various buffers and is used as a work memory of the central processing unit 100. The ROM 120 stores a control program and initial service data for performing calls and various functions. Under the control of the central processing unit 100, the switching circuit 130 switches various tone and voice data, connection between extension terminals, connection of a trunk line, and the like. The general subscriber circuit 140 performs interfacing between a general telephone set of a plurality of subscribers and the apparatus. The trunk line circuit 180 is connected to the external trunk line and implements the call in the above-mentioned exchange period with the trunk line. The ring generator 150 outputs a ring signal in the form of a square wave to the general subscriber circuit 140. The key phone subscriber circuit 160 performs interfacing between a plurality of key phone apparatuses and a device, and the key phone apparatus has a character display unit so that the subscriber can know the overall operating state of the system and the input phone number. In particular, the key phone subscriber circuit 160 includes a digital circuit unit, and it includes a digital line interface module (DLI). The DLI refers to a board for connecting a digital telephone to a system, and provides interfaces such as a system, a computer, a terminal, and a modem. The computer also performs the interfacing through the following CTI (Computer Telephony Interface) matching circuit 165. The tone generator 170 is controlled by the central processing unit 100 and forms a trunk loop by visualizing the trunk line. In addition, an incoming signal received through the CO is interfaced. The DTMF receiver 190 analyzes the DTMF signal generated from the subscriber of the general subscriber circuit 140. The subscriber's telephone number may be known by the operation of the DTMF receiver 190. On the other hand, the DTMF transmitter 200 outputs the DTMF signal to the switching circuit 130 under the control of the central processing unit 100. The clock circuit 105 serves as a timer for counting a predetermined time preset under the control of the central processing unit 100 or performs a reference clock operation of the private branch exchange. The CTI matching circuit 165 is subscribed to terminals that process digital data such as a computer. In view of the present invention, terminals such as the key telephone or the computer joined to the CTI matching circuit 165 are provided with a character display device for displaying character information. For reference, character display devices provided in terminals such as a key telephone and a computer are implemented as a liquid crystal display (LCD) or a computer monitor.

FIG. 2 is an area of the RAM 110 shown in FIG. 1, which is a memory table indicating an area where character information transferred to a subscriber station is stored according to an embodiment of the present invention. The RAM 110 stores L character information.

Referring to FIG. 2, the character information No. indicates the order occupied by the character information in the RAM 110 area, and the order can be changed by the user's operation. The setting authority is referred to when the user who is the subscriber of the PABX requests the character information setting. That is, the setting authority is previously selected and registered by the system administrator, and the corresponding character information can be set only for the registered subscriber. In FIG. 2, 'HIGH' and 'LOW' are distinguished. A character information area corresponding to 'HIGH' is an area set by a subscriber having a high authority, and a character information corresponding to 'LOW' This is an area that can be set by a subscriber having authority. The character information name indicates the type of the corresponding character information. The system administrator must also set the character information type in advance and allocate the storage area, which does not have the right to modify by the subscriber. The character information content is the content of a predetermined message to be provided as character information. This allows the corresponding subscriber to modify and input according to the setting authority.

3 is a flowchart illustrating a process of storing character information input from a subscriber station according to the present invention in the same format as the memory table shown in FIG.

The description of FIG. 3, which will be described below, shows a process in which a subscriber who wishes to store a message corresponding to a caller, that is, a character information, inputs using the key telephone. That is, the central processing unit 100 processes the setting of the character information by using the key telephone as the caller has character information to be set.

First, in step 301, it is determined whether there is an input of a character information setting key from the key telephone. If there is an input, in step 302, it is determined whether the current PBX is in a character information setting mode. If it is determined in step 302 that the character information setting mode is in effect, the character information setting mode is canceled in step 314. That is, the character information setting key performs a toggle operation. If it is determined in step 302 that it is not in the character information setting mode, the character information setting mode is entered in step 303 and N = 1 is initialized. Here, initializing N to 1 means to use the character information memory table implemented in the RAM 110 from the beginning. After performing the initializing operation in step 303, the character information name of the Nth character information in the character information memory table is displayed on the character display device of the key telephone of the subscriber who is the caller. The caller checks the displayed character information name to see if it is the character information that the caller has set. Here, if the caller wants to set the character information, he / she will input the selection key, otherwise, enter the progress key to view the next character information name. That is, in step 305, it is determined whether the caller has input a selection key. If it is determined in step 305 that the selection key is not input, it is determined in step 306 whether a progress key is input. If it is determined in step 305 that a progress key has been input, in step 307, N is increased to N + 1 in preparation for the operation, and step 304 is repeatedly performed. In step 304, the N + 1th character information name is displayed. If it is determined in step 308 that there is no input of the progress key, step 305 is repeatedly performed. If it is determined in step 305 that the selection key is input, it is determined in step 308 whether the caller has the right to set the Nth character information. If it is determined that there is no setting right, an error message indicating that there is no setting right is displayed in step 313, and the step 304 is executed again. If it is determined in step 308 that the user has the setting authority, the caller is requested to input a message corresponding to the character information in step 309. Then, in step 310, a character information message is input from the caller. When the input is completed, the caller inputs the selection key. In step 311, the caller determines whether the selection key is input. If the selection key is not input in step 311, the operation of step 310 is performed again. If it is determined that the selection key is input in step 311, the input character information message is stored in the Nth memory table in step 312, and the character information setting mode is terminated in step 314, and the character information setting process is terminated.

3, the caller can advance the process of inputting character information by using the computer connected to the CTI matching circuit 165. In addition, the caller can access the Internet, the modem, the ISDN, The CTI matching circuit 165 receives the character information input through the data line, and the setting process can be automatically or manually performed.

4 is a flowchart illustrating an operation of providing character information set in the setting process of FIG. 3 to a terminal subscribed to the PABX through a character display device provided in the terminal according to the present invention.

Referring to FIG. 4, it is determined in step 401 whether T1 of the timer implemented in the clock circuit 105 has expired. The timer T1 is a reference time used by the CPU 100 to search the character information memory table at a predetermined time interval. If there is character information, the timer T1 provides the terminal with the timer T1. That is, the timer T1 performs an operation of informing the central processing unit 100 that the predetermined time has passed. Accordingly, when the timer T1 expires in step 401, it means that it is time to provide the character information, so that M is initialized to 1 in step 402. [ Herein, the initialization of the M is performed to check whether the subscriber is the first subscriber to the terminal having the character display device among the plurality of subscribers subscribed to the PABX. That is, it checks from the first terminal to select a terminal that can receive the character information. Therefore, it is determined in step 403 whether M is greater than L. [ Since L indicates the number of terminals subscribed to the PABX, if M is greater than L in step 403, it means that all terminals are checked. Therefore, in step 411, Lt; RTI ID = 0.0 > T1 < / RTI > If it is determined in step 403 that M is less than or equal to L, it is determined in step 404 whether the Mth terminal (extension subscriber) is a terminal equipped with a character display device. This means that a terminal that does not have a character display device has no meaning even if character information is provided, and therefore, it is an operation for checking whether there is a next terminal equipped with a character display device. Accordingly, if it is determined in step 404 that the M-th terminal (extension subscriber) does not have a character display device, M is incremented to M + 1 to check the next terminal in step 406, and step 403 is performed again . If it is determined in step 404 that the M-th terminal (subscriber) is a terminal equipped with a character display device, in step 405, the character information number N in the character information memory table is initialized to 1. That is, it is a measure for searching character information from the beginning. In step 407, the N is compared with the size K of the character information in the character information memory table. If it is determined that N is larger than K, it means that all the information in the character information memory table has been retrieved. Therefore, if it is determined in step 407 that N is larger than K, do. If it is determined in step 407 that N is less than or equal to K, it means that there is a character information memory table that has not yet been retrieved. Therefore, it is checked in step 408 if character information is stored in the Nth item of the character information memory table . If it is determined in step 408 that character information is not stored, N is increased to N + 1 in step 409 to check the next character information item. Then, the operation in step 407 is performed again. If it is determined in step 408 that the character information is stored in the Nth item of the character information memory table, the Mth terminal (extension subscriber) provides the character information of the Nth item of the character information memory table in step 410. The provided character information is displayed on the character display device provided in the terminal. Then, step 409 is executed again to retrieve character information of the next item in the character information memory table. Meanwhile, the manner in which the character information is provided to the terminal depends on the structure of the private branch exchange, and also depends on the type of the terminal.

On the other hand, when character information is provided to the terminal, the same character information may be provided to all subscribers for a predetermined time as described above. However, according to the needs of the caller, or by the request of the system administrator, a method of providing once or repeatedly for a predetermined period of time is also possible by the application of the operator. When the terminals are divided into groups, it is also possible to provide specific character information in a specific group.

Although the present invention has been described in detail with reference to specific embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the scope of the present invention. Therefore, it should be understood that the scope of the present invention should not be limited by the above-described embodiments, but should be defined by the appended claims rather than the following claims.

In the case where the present invention is implemented according to the above description, when the information to be shared by the subscribers is transmitted to the terminal subscribed to the private branch exchange, it is advantageous to use the character information providing function with low utilization rate more efficiently .

In addition, important meeting call or. It increases the efficiency and increases the convenience when performing work such as business communication and instruction.
