Abstract

PURPOSE:To select it for each trunk line based on the set contents of a state identification memory when a call is incoming to the trunk line whether the call is made incoming to an individual incoming call extension or connected to a voice guide device by providing a means to set a state to either connection to the individual incoming call extension or connection to the voice guide device by the dial operation of an extension. CONSTITUTION:An extension telephone set 2 is connected to a call originating register 6 by the off-hook of the extension telephone set 2. A central control unit 4 sets data to a state identification memory 8 in a main memory 5 for discriminating and deciding whether the call is connected to the extension telephone set or to a voice guide device 7. After that, when there is the incoming call to a central office line 3, a memory corresponding to a call incoming trunk is read from the state identification memory 8 in the main memory 5 by the central control unit 4 and it is selected whether the call is connected to the extension telephone set or to the voice guide device 7.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an individual call termination connection system that connects to an individual call termination extension line when a call is received from a central office line.

[Prior art] The conventional individual incoming call connection method has the function of connecting to an individual incoming extension when a call arrives at the central office line, but when the incoming individual extension is not available, it is possible to connect to another extension or a relay stand. It was like that.

[Problems to be Solved by the Invention] However, in the conventional individual terminating Ml system described above, when an individual terminating extension is absent, when connecting to another extension or relay stand, the call is handled as a transfer destination extension or relay stand. This method has the disadvantage that it is complicated because it is necessary to contact the person in advance.

[Means for Solving the Problems] The technical means of the present invention for solving the above-mentioned drawbacks is to provide an audio system capable of recording and transmitting messages from extensions in a private branch exchange having a function of connecting to individual incoming extensions. In addition to providing a guidance device, a setting means is provided for setting the state identification memory provided for each central office line trunk to either connection to an individual incoming extension or connection to a voice guidance device by dialing the extension. This is an individual call connection connection system which is provided with a selection means for selecting for each office line whether the call is to be received on the individual call extension or to be connected to the voice guidance device based on the setting contents of the status identification memory when a call is received from the office line.

[Embodiment] An individual incoming call connection system according to an embodiment of the present invention will be described below based on the accompanying drawings. FIG. 1 is a block diagram showing a circuit configuration of an individual incoming call connection system according to an embodiment. In the figure, 1 is the main sketch (SW), 2 is the extension telephone (STA)
, 3 is the central office line trunk (TRK), and 4 is the central control unit (C
C), 5 is a main memory (MEM), 6 is an outgoing register (ORT), and 7 is a voice guidance device (TKT). The main sketch 1 has a function of switching connections between the extension telephone 29, the office line trunk 3, the call register 6, and the voice guidance device 7 based on commands from the central control device 4. Further, the voice guidance device 7 is configured to include, for example, a recording tape or the like capable of recording and transmitting messages from an extension. As shown in FIG. 3, the main storage device 5 includes a state identification memory 8 provided for each central office line trunk 3 (0, 1, . . . n). In this state [li separate memory 8,
In the main sketch I, either the connection to the individual incoming call extension or the connection to the voice guidance device is set, or the data thereof is written. Further, the central control device 4 sets data in the state identification memory 8 to either the state of connection to the individual incoming extension or the connection to the voice guidance device 7 by dialing a special number from the extension telephone 2. It functions as a means. In addition, when a call arrives on a central office line, the central @fI control device 4 selects for each office line whether the call is to be received on an individual incoming extension or to be connected to the voice guidance device 7 based on the settings in the status identification memory 8. It has a function as a means and also has a function of driving the main sketch 1 according to this selection.

Therefore, according to the individual incoming call connection system according to this embodiment, as shown in FIG. Dial the special number from telephone 2. As a result, the central control device 4 sets data in the state identification memory 8 in the main storage device 5 so that it can be determined whether the telephone is an extension telephone or whether it is connected to the voice guidance device 7.

After that, if there is an incoming call to central office trunk 3,
The central control device 4 reads out the memory corresponding to the incoming trunk from the state identification memory 8 in the main storage device 5,
Select whether to connect to the extension telephone or the voice guidance device 7. If the connection is to the voice guidance device, as shown in FIG. The connection is made to the main sketch, and the recorded message is sent to the office line trunk 3.

That is, by dialing the extension for individual incoming calls, data is set in the status identification memory 8 provided in the main storage 5 to indicate whether to connect to the extension or to the voice guidance device 7, and when connecting to the individual incoming calls, Since the status identification memory 8 selects whether to connect to an extension or to connect to the voice guidance device 7, the voice guidance device 7 can be used when the user is absent.

[Effects of the Invention] As explained above, according to the individual incoming call connection system of the present invention, when the individual incoming call extension is unavailable, any message can be sent to the incoming call by dialing a predetermined number. What happens if it is possible to send it? Therefore, it is possible to send an appropriate message in response to an incoming call, and there is no need to use other call receiving methods such as connecting to another extension, which eliminates the complexity of answering incoming calls to the Ikeuchi line. There is an effect that it can be done.

[Brief explanation of the drawing]

Fig. 1 is a block diagram showing the circuit configuration of an individual incoming call connection system according to an embodiment of the present invention together with one connection state thereof, Fig. 2 is a diagram equivalent to Fig. 1 showing another connection state, and Fig. 3 is an embodiment. FIG. 1: Main sketch (SW) 2: Extension telephone (STA) 3: Office line trunk (TRK) 4: Central control unit (CC) 5: Main memory (MEM) 6: Outgoing call register (ORT) 7: Voice guidance device (TXT) 8: Status identification memory

Claims (1)

[Claims] A private branch exchange that has the function of connecting to an individual incoming extension is equipped with a voice guidance device that can record and send messages from the extension, and a status identification memory provided for each central office line trunk that allows individual calls to be sent by dialing the extension. A setting means is provided that can set the state to either connection to the incoming extension or connection to the voice guidance device, and when a call is received from the central office line, the call can be set to the individual incoming extension or the voice guidance device. An individual incoming call connection method characterized by providing a selection means for selecting whether to connect to each office line.
