Abstract

PURPOSE:To decrease the load of an exchange by providing a key operation supervising means in terminal equipment, and ignoring a key operation when the key operation is executed and it has no validity. CONSTITUTION:When a response key 17 is operated, whether or not an incoming call is arriving is decided, when it is decided that the incoming call is arriving, an operating signal is sent to a private exchange 2, and further, a key confirming sound is generated. Consequently, when the operating signal of the response key 17 arrives, the private exchange 2 decides whether or not is valid, when it is decided to be invalid, an ignoring processing is not executed. Thus, the burden of the private exchange 2 is reduced, and since the key confirming sound is not generated in a period other than that of the incoming call in an attendant board 5, and inconvenience to cause a mistake to an operator as if the operation of the response key 17 is valid can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a terminal device such as a relay stand used in an electronic switching system.

(Prior Art) In recent years, electronic private branch exchange systems have been widely used in offices and business establishments. This type of system includes, for example, a private branch exchange (PBX) 2 connected to a central office exchange (not shown) via a central office line 1, as shown in FIG. It consists of a telephone 4 and a relay stand 5. When an incoming call occurs via the central office line 1, the private branch exchange 2 detects this and sends an incoming call signal to the relay console 5, which causes the relay console 5 to generate a ring tone and receive the call to the relay operator. Notify that this has occurred. In this state, when the relay operator responds by pressing the response key, a response key operation signal is sent from the relay console 5 to the private branch exchange 2 to inform that the call has been answered, and in response, the private branch exchange 2 confirms that the call is being received. After confirming whether this is the case, a call start signal is sent to the relay stand 5, and a communication path is formed between the office line 1 and the relay stand 5. The relay operator is then able to communicate with the calling party.

Then, when the relay operator operates the dial keys to send extension number information to the private branch exchange 2, the corresponding extension telephone 4 is called by the private branch exchange 2, and the caller answers the call by going off-hook, and the relay operator When the on-hook operation is performed, a communication path is formed between the central office line 1 and the extension telephone 4 via the private branch exchange 2, and a conversation between the calling party and the person speaking on the extension telephone 4 is possible thereafter. .

(Problem to be Solved by the Invention) However, the relay console 5 of this type of conventional system constantly performs response key operation processing as shown in FIG. 4, and the response key operation is detected in step 4a. Each time, an operation signal is sent to the private branch exchange 2 in step 4b, and a key confirmation sound is generated in step 4c.

Therefore, even if the relay operator accidentally presses the answer key when no incoming call has occurred, the operation signal is sent from the relay console 5 to the private branch exchange 2, and as a result, the private branch exchange 2 presses the answer key each time. It is necessary to check whether the operation of the key is valid, and if it is not valid, to ignore the operation of the response key, which causes a problem of increased load.

The present invention focuses on this point and aims to provide a terminal device for an electronic switching system that eliminates the need for processing for meaningless key operations on the terminal side of the switching device, thereby reducing the load on the switching device. .

[Configuration of the Invention (Means for Solving the Problems) The present invention includes an exchange device and a terminal device connected to the exchange device, and when a key operation is performed on the terminal device, a key operation corresponding to the operation is provided. In a terminal device of an electronic switching system that transmits a signal to the switching device to execute a predetermined control, the terminal device is provided with a key operation monitoring control means, and when a key operation is performed, a signal corresponding to the key operation is detected. The above-mentioned key operation is accepted only when there is validity, and the above-mentioned key operation is ignored when there is no validity.

(Function) As a result, even if a meaningless key operation is performed, this key operation is determined to be invalid by the key operation monitoring control means and is ignored. Therefore, meaningless key operation signals are no longer sent from the terminal device to the exchange device, and the exchange device no longer needs to perform processing to ignore key operations, reducing the processing load accordingly. becomes possible.

(Example) Next, the details of the terminal device of the present invention will be explained using a relay stand as an example. FIG. 1 shows the configuration of this relay stand. This relay stand includes a control unit 10 equipped with a microcomputer, and this control unit 10 is connected to the extension 3 via an interface 11 for the relay stand. The control unit 10 also includes, for example, an LED drive circuit 12 that turns on or blinks a light emitting diode (LED) 16 when an incoming call occurs, an operation monitoring circuit 13, and a circuit that detects whether or not the connector 18 of the headset 19 is connected. A connection detection circuit 14 and a speaker drive circuit 15 that generates an incoming ring tone etc. from the speaker 20.
are connected to each other. Of these, operation monitoring circuit 1
3 detects when the response key 17 is pressed and notifies the control unit 10 of this.

By the way, the control section 10 includes an operation monitoring control means 1 in addition to a control section main body 10a that performs various controls related to relay control.
0b. The operation monitoring control means 10b determines whether or not the operation is valid when the response key is operated, and causes the control section main body 10a to execute the response key operation processing only when the operation is valid.

With this configuration, in the standby state, the control unit 10 of the relay stand repeatedly monitors the arrival of incoming calls and the operation of the response key 17 as shown in FIG. 2. When an incoming call signal arrives from a private branch exchange (not shown) in this state, the control section 10 of the relay stand outputs a drive signal to the speaker drive circuit 15, thereby causing the speaker 20 to generate an incoming call tone. Then, when the operator confirms this ring tone and presses the response key 17,
The control unit 10 detects this in step 2a as shown in FIG. 2, and then determines in step 2b whether or not an incoming ringing tone is being generated.

If the incoming ring tone is currently being generated as described above, the control unit 10 determines that the operation of the response key 17 is appropriate,
After stopping the generation of the incoming ring tone, the process moves to step 2C, where an operation signal of the response key 17 is sent to the private branch exchange, and further, in step 2d, a key confirmation tone is generated from a sounder (not shown). That is, normal processing in response to the operation of the response key 17 is performed. On the other hand, when the private branch exchange detects the arrival of the response key 17, it immediately executes an immediate response process, and in this process sends a call start signal to the relay console and creates a communication path between the central office line and the relay console. to enable communication.

On the other hand, in the standby state, the operator accidentally pressed the response key 1.
7, the controller 10 presses the answer key 1 based on the determination in step 2b as to whether or not an incoming call is in progress.
7 is judged to be invalid and meaningless. Then, as shown in FIG. 2, the control returns to the standby state of various monitoring controls without transmitting the operation signal or generating the key confirmation sound. Therefore, in this case, no signal is sent from the relay stand to the private branch exchange, and as a result, the private branch exchange does not have to perform any processing to ignore the operation of the response key.

In this embodiment, when the response key 17 is operated, it is determined whether or not an incoming call is in progress, and only when it is determined that an incoming call is in progress, an operation signal is sent to the private branch exchange, and the key is further confirmed. Since the sound is generated, the private branch exchange does not have to judge whether or not the response key operation signal is valid when it arrives, and ignore it if it is not valid. The burden on the switching equipment can be reduced. Furthermore, since the key confirmation sound is not generated at the relay stand except when an incoming call is received, it is possible to prevent the operator from having the illusion that the operation of the response key 17 is valid.

Note that the present invention is not limited to the above embodiments. For example, in the above embodiment, the operation of the response key 17 is monitored even during periods other than when an incoming call is generated, but operation of the response key 17 may not be monitored during a period other than during an incoming call. Furthermore, in the above embodiment, a case has been described in which operation and monitoring control is executed for the response key on the attendant console, but it can also be applied to other keys on the attendant console and various keys on telephones, facsimile machines, data terminal devices, etc. other than the attendant console. It's okay. In addition, the control procedures and control contents of the operation monitoring control means can be modified in various ways without departing from the gist of the present invention.

[Effects of the Invention] As described in detail above, according to the present invention, the terminal device is provided with a key operation monitoring control means, and when a key operation is performed,
By accepting the above key operation only when the key operation is valid, and ignoring the above key operation when it is not valid, the process for meaningless key operations on the terminal side of the exchange device is improved. It is possible to provide a terminal device for an electronic switching system that can be made unnecessary, thereby reducing the load on the switching device.
