Abstract

PURPOSE:To allow a telephone set terminal to interrupt a data terminal equipment when the connection is not desired by the telephone set terminal by devising the system such that it is informed to the telephone set terminal in voice that the destination of communication of the telephone set terminal is the data terminal equipment before the connection of the telephone set terminal and the data terminal equipment. CONSTITUTION:A telephone set terminal 10, a data terminal equipment 20, and announcement equipment 30 or the like and a central controller 50 are communicated via a common bus 70 and a communication control channel of a channel equipment 40. Moreover, the information or the like stored in a main storage memory 60 is read from the central controller 50 via the common bus 70. When a call comes from the telephone set terminal 10 to the data terminal equipment 20 or vice versa, before the connection of the telephone set terminal 10 and the data terminal equipment 20, it is informed to the telephone set terminal 10 in voice that the destination of communication of the telephone set terminal 10 is the data terminal equipment 20. Thus, when the telephone set terminal 10 keeps the communication mode, it is automatically connected to the data terminal equipment 20, and when the connection is not desired by the telephone set terminal 10, the telephone set terminal 10 interrupts the line.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a terminal connection method for a storage program controlled electronic exchange that accommodates a plurality of telephone terminals and data terminals. (Prior art) Regarding the method of connecting data terminals and facsimile terminals to electronic exchanges using telephone exchange lines, see PBX and Data Communication in the rISDN Era, by Shin-bu Fujishima, Link Telecom Co., Ltd., pp. 132- 135". The method of connecting terminals using this telephone exchange line, which is widely used because it is easy to connect a data terminal or facsimile terminal instead of a subscriber's telephone, is ( 1) use an acoustic coupler after setting up a line, (2) use a changeover switch to switch to a data terminal after calling the other party using the telephone, and (3) a telephone with a built-in modem and network control device. When connecting an ordinary telephone or facsimile terminal, if the terminal is in a state where it is possible to make a call regardless of the attributes of the terminal, an outgoing call request,
Dial reception, call, response, call and connection transition. In such conventional terminal connection systems, if a call is made from a normal telephone and an incorrect dial number is dialed, even if the call arrives at the data terminal, the connection will be successful. Furthermore, even if a call arrives from a data terminal to a telephone terminal, as in the case described above, if the call is answered, the connection will be established normally. Also, the electronic exchange does not allow connection between the above terminals. For example, even if you return a busy tone to the calling party, you will know that a connection cannot be established using this method, but you will not know the reason.

[Problem to be solved by the invention]

With the terminal connection method described above, it is possible, for example, to receive a call from a telephone to a data terminal without intending to perform data communication, and when the receiving data terminal answers, the data terminal automatically sends an audible signal tone to the calling telephone. I end up sending it out. As a result, the caller suddenly hears an audible signal tone,
The reason for this is difficult to understand, and it is difficult to say that it is user-friendly. Conversely, if a call is made from a data terminal and the call is mistakenly received by a regular telephone, even if the receiving party's telephone answers, the call will remain in a no-call state because the calling party is a data terminal. will occur. The main purpose of the present invention is that when connecting terminals with different terminal attributes, before connecting the terminals, one of the terminals is notified by voice, and the connection service of the electronic exchange is activated. The objective is to provide a terminal connection method that improves the performance of the device.

[Means for Solving the Problems] In a storage program controlled electronic switching system having a main memory storing a subscriber database in which attribute information of terminals is registered, a central control unit, an announcement device, and a channel device, a calling terminal Data information for specifying the announcement device to be connected is provided in the main memory based on the combination of terminal attributes of the calling terminal and the receiving terminal, and the central control unit stores data information in the subscriber database based on the dialed numbers of the calling terminal and the receiving terminal. The extracted terminal attributes are used to determine the desired announcement device to be connected from the aforementioned data end axis. If the calling party is a terminal with a telephone function and the called party is a data terminal, the central control unit sends a message via a communication path device between the calling terminal and the specified announcement device before calling the called terminal. By establishing a time connection, the announcement device sends a voice message to the calling terminal indicating that the called terminal is a data terminal, then releases the communication path, and sends a ring tone to the calling terminal.1 called terminal send a call signal to the other party. In addition, if the calling party is a data terminal and the receiving party is a terminal with a telephone function, if the receiving terminal responds, an announcement is made by connecting the communication path between the receiving terminal and the specified announcement device for a certain period of time. After the device sends a voice to the receiving terminal to the effect that the calling terminal is a data terminal, the communication path is released and the calling terminal and the receiving terminal are connected in a state where they can talk. By sending the dial number included in the activation signal to the announcement device, the announce device converts the dial number into a voice signal, making it possible to easily identify the calling terminal and the receiving terminal. Furthermore, by providing the announcement device with a time limit monitoring function, there is no need for time limit monitoring on the electronic exchange main body side. However, the communication path between the announcer and the terminal is released by sending a communication path release request signal from the announcer to the main body of the electronic exchange. [Operation] According to the terminal connection method of the present invention, when a call is received from a telephone terminal to a data terminal, or when a call is received from a data terminal to a telephone terminal, the telephone terminal can be notified by voice that the other party of the call is a data terminal. As a result, if the telephone terminal maintains this state, it can automatically connect to the data terminal, and if it does not wish to connect with the data terminal, it can simply disconnect from the telephone terminal. As a result, it is possible to solve the conventional problem of hearing an audible signal immediately after receiving a call from a data terminal and answering it, or remaining silent after answering an incoming call from a data terminal. It is possible to provide an easy-to-use user interface that allows easy control of connections. Further, since the time limit monitoring function can be shared between the electronic exchange main body or the announcement device, it is possible to respond flexibly depending on the performance of the electronic exchange system and the division of functions. [Example] Hereinafter, an example of the present invention will be described using the drawings. 1st

FIG. 2 is an example showing the structure of data that specifies the announcement device 30 from a combination of terminal attributes. The terminal attributes are specified from the subscriber database stored in the main memory 60 using the housing location of the terminal, dial number, etc. as keys, and the above-mentioned data is used. The announcement device 30 is identified from the terminal attributes of the calling side and the terminal attributes of the called side. An example of the signal sequence and processing between the central control unit and the terminals according to the present invention will be explained using FIG. Here, it is assumed that a call is made from the telephone terminal 10 and received at the data terminal 20, and the central control unit 50 performs time-limited monitoring. First, a call request from the telephone terminal 10 is sent to the central control unit 50 via the call route block [40] and the common path 70, and then the dialed digits of the data terminal from the telephone terminal 10 are transmitted to the central control unit 50 in the same way as the call request signal. It is sent to the control device 50. The central control unit 50 reads out the subscriber database in the main memory 60 via the common bus 70, identifies the originating terminal attribute, for example, that it is a telephone, from the housing position of the originating terminal, and identifies the originating terminal attribute from the dial number of the terminating terminal.

Then, the central control device 50 controls the communication path device 40 via the common bus 70 so that the announcement device 3 identified as the calling side telephone terminal 10
A call path is set so that a call can be made to 0, and an activation signal containing the dial number of the destination data terminal 20 and instructing to start an announcement is sent to the announcement device 30. At the same time, the central control unit M50 starts a timed monitoring function using a timer. The announcement device 30 converts the received dial digits of the destination data terminal into an audio signal, and announces to the calling side that the destination terminal is a data terminal. When a certain period of time has elapsed due to the time-limited monitoring function, the central controller 50 releases the call path between the telephone terminal 10 and the announcement device 30, sends a ringback tone to the telephone terminal 10 on the calling side, and sends a ringback tone to the data terminal 20 on the called side. Sends a call signal to. Thereafter, a normal call connection sequence proceeds. Next, with reference to FIG. 4, a signal sequence between the central controller and the terminal will be described for an embodiment in which a call is sent from a data terminal, received at a telephone terminal, and the central controller performs time-limited monitoring. A call request from the data terminal 20 is sent to the central control unit W50 via the communication path W40 and the common bus 70, and the dialed digits of the telephone terminal are sent from the data terminal 20 to the central control unit 50 in the same manner as the call request signal. sent to. The central control unit 250 also reads out the subscriber database from the main memory 6 via the common bus 70, identifies the originating terminal attribute from the accommodation position of the originating terminal 1, identifies the terminating terminal attribute from the dial number of the terminating terminal, and then Using the data shown in Figure 2,
The announcement device [130] is identified from the combination of terminal attributes. The central controller 50 then sends data to the data terminal 20 on the sending side.
Sends a ring pack tone. A calling signal is sent to the telephone terminal 10 on the receiving side. Upon receiving the response signal from the telephone terminal 10, the central control unit 50 controls the communication path device 40 via the common bus 70, thereby calling the announcement device 3 identified as the data terminal 20 on the receiving side.
0, and sends to the announcement device 30 an activation signal that includes the dial number of the data terminal 2O obtained from the accommodation position of the calling terminal and instructs to start the announcement. At the same time, the central controller 50 starts a timed monitoring function using a timer. The announcement device 30 converts the received dialed digits of the calling terminal into a voice signal and announces to the called party that the calling terminal is a data terminal. When a certain period of time has elapsed due to the time monitoring function, the central control device 50 controls the communication path device 40 to release the communication path between the telephone terminal 10 and the announcement device 30. A path connection is established between the data terminal 20 and the telephone terminal 10 so that they can talk over the phone. Thereafter, a normal call connection sequence proceeds. In FIG. 5, the time-limited monitoring function is not provided by the central controller 50;
An example provided in the announcement device 30 will be described. This is a case where a call is originated from the telephone terminal 10 and received at the data terminal 20. In this case, the process from the call request from the telephone terminal 10 to the connection between the telephone terminal 10 and the announcement device 30 is performed in the same way as in the case of FIG. Then, the central control device 50 sends to the announcement device 30 an activation signal that includes the dial number of the destination data terminal 20 and instructs to start the announcement. The announcement device i30 converts the received dial digits of the destination data terminal into a voice signal, and announces to the calling side that the destination terminal is a data terminal. When a certain period of time has elapsed due to the time monitoring function, the announcement device 30 sends a path release request signal to the central control unit [50] requesting release of the communication path. Upon receiving the path release request signal, the central control unit 50 releases the path between the telephone terminal 10 and the announcement device 30, sends a ringback tone to the telephone terminal 10 on the calling side, and sends a paging signal to the data terminal 20 on the called side. Send. Thereafter, a normal call connection sequence proceeds. Next, with reference to FIG. 6, an example of a signal sequence and processing between the central control unit and the terminal will be described for an embodiment in which a call is originated from a data terminal, received at a telephone terminal, and an announcer performs time-limited monitoring. The process from the transmission request from the data terminal 20 to the sending of the activation signal to the announcement device 30 is performed in the same manner as in the case of FIG. Then, the announcement device 30 converts the received dialed digits of the calling terminal into an audio signal, and announces to the called party that the calling terminal is a data terminal. When a certain period of time has elapsed due to the time monitoring function, the announcement device 30 sends a path release request signal to the central control device 50 requesting release of the call path. Upon receiving the path release request signal, the central control unit 50 releases the path between the telephone terminal 10 and the announcement device 30, and sets up a communication path between the data terminal 20 and the telephone terminal 10. In the explanation of FIGS. 3 to 6 so far, the telephone terminal 10
The explanation has been made on the premise that the data terminal 20, the announcement device 30, etc., and the central control device 50 can communicate via the common bus 70 and the communication control channel of the communication channel device 40, but it is shown in FIG. Needless to say, the telephone terminal 10, the data terminal 20, the announcement device 30, etc., and the central control device 50 may be directly connected to each other via the common bus 70 so that they can communicate with each other. [Effects of the Invention] According to the terminal connection method of the present invention, when a call is received from a telephone terminal to a data terminal, or from a data terminal to a telephone terminal, the telephone terminal is connected before connecting the telephone terminal and the data terminal. Since the terminal side can be notified by voice that the other party of the call is a data terminal, if the telephone terminal side maintains this state, it can automatically connect to the data terminal. Also, if you do not wish to connect to a data terminal. It becomes possible to disconnect from the telephone terminal side. This solves the problem of hearing an audible signal immediately after receiving a call from a data terminal and answering it, or remaining silent after answering an incoming call from a data terminal. It is possible to provide an easy-to-use user interface that allows easy control.
