Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a button telephone device comprising a plurality of key telephones and a main device for controlling connections between the key telephones and central office lines. The present invention relates to a setting method for a button telephone device, in which operational data is read and operation settings of the button telephone device are made based on this data.

Operational data in a button telephone device is, for example, (1
) Data indicating which key telephone the incoming call will be made to when there is an incoming call from the central office line @ 121
(3) data indicating that calling from a central office line is prohibited from a 1 yen fixed key telephone; (3) data indicating prohibition of making a specific dialing signal sent from a button telephone; This is the data used for this purpose. This operation data setting is normally performed by turning on or off each switch of an operation data setting switch circuit (hereinafter referred to as a setting switch circuit) in the main device, such as a dip switch.

Now, assuming that the control means of the main device reads the operational data set in the setting switch circuit in this way and performs operation settings for providing various services of the button telephone device based on this operational data, the following conventional methods are used. There is a method for setting up a button telephone device.

First, in the initialization operation when the key telephone device is powered on, the control means of the main device reads the set operational data into the memory of the control means, and based on this read operational data, all buttons are This is a method for setting the button telephone device and □′□ position for setting the operation of the telephone device. However, with this setting method, when resetting new operational data to the setting switch circuit, it is necessary to read the operational data into the memory in an initialization operation. In other words, when resetting new operational data, it is necessary to turn off the power to the key telephone device and then turn it on again, which may cause inconveniences such as disconnecting the call from the key telephone device that was in use. was there.

Second, each time the control means of the main device performs operation control corresponding to the operational data, the button telephone device is configured to read the operational data set each time and control the operation of the button telephone device based on this operational data. It's a method. however,
This read operational data is not stored in the memory within the control means.

In addition, the operational data set by a setting switch circuit, which is generally composed of dip switches, etc., is once converted into data (binary encoded data) that can be directly recognized by the control means, and then read into the control means. Therefore, it takes time to read the operational data. Therefore, in this setting method, the control means reads the operational data every time it is necessary, so even when the operating load of this control means is heavy, the operation of reading the operational data is repeated many times. Another disadvantage is that the operation processing time of the control means becomes long and efficient operation cannot be performed.

The present invention focuses on the above-mentioned circumstances, and makes it possible to change operational data without interrupting the operation of the key telephone device, and also makes it possible to reduce the operation processing time of the control means of the main device when the operation load of the control means is large. An object of the present invention is to provide a setting method for a button telephone device that can operate efficiently without causing problems.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

Here, the setting switch circuit (9) is set with operational data such that incoming calls are made only from a specific key telephone, and operational data that prohibits calling from a specific key telephone to a central office line. do.

The control circuit (8) of the control means (8) reads the operation data from the setting switch circuit (9) by, for example, converting the output PO (0) of the output interface circuit (80) into a logic "
The input PI(o) of the input interface circuit (70) is set to "L" level and PO(1) is set to the logic "H" level.
It is only necessary to judge whether this input bit is “H”
If the level is "L", the switch (51) is off, and if the level is "L", the switch (51) is on. In this way, the control circuit ω determines the switch state of each switch Gυ (54). Then, the operation data set by the setting switch circuit (9) is read, and this data is converted into binary encoded data and stored in the memory CJ11.At this time, such operation data reading operation of the control circuit , is performed periodically based on a signal outputted every predetermined time from a timer circuit aO that counts a predetermined time.

Now, the operation of this button telephone device shown in FIG. 1 will be explained.

First, consider incoming calls from the central office line. For example, the central line α
When there is an incoming call from υ, the central office line interface circuit (6
) detects that there is an incoming call from the central office line αυ, and sends a data signal indicating this to the control circuit (to). The control circuit CIl receives this data signal and operates the button telephone (
A data signal is sent out via an LEDK receiving circuit (3), (41, etc., not shown) for displaying the station line in use, which corresponds to the station line 0υ such as 1), 121, etc.

Also, based on the operational data stored in the memory Q1), the control circuit (2) determines which key telephone is to be called, and sends out a data signal so that the key telephone makes a ringing tone. In a button telephone device, generally any button telephone can answer a call from a central office line, so here it is assumed that the button telephone (2) is used to answer the call. When you respond to a call from the central office line Qυ by performing a prescribed operation on the button telephone (2), a data signal indicating this is sent to the terminal interface circuit (4).
is sent to the control circuit (to) via. The control circuit circle is
Based on this signal, the office line interface circuit (6) connects the office line aυ, operates the cross point 15), and connects the button telephone (
2) and the central office line αυ. Meanwhile, each terminal interface circuit (3).

(4) The control circuit is controlled through each button telephone (■).

(A data signal is sent to the LED for displaying the used station line (not shown) corresponding to the station iIQυ such as No. 2 to indicate that a call is in progress.

Second, consider central office line transmission. For example, when a key telephone (1) makes a call to the central office line Q3, a data signal indicating this is sent to the terminal interface circuit (3).
is sent to the control circuit (to) via. The control circuit ■ is
When this signal is received, it is determined from the operational data stored in the memory 1) Qυ whether or not calling from the central office line from the key telephone 1k(1) is prohibited. Here, the key phone (1)
Assuming that calling from the office line is not prohibited, the control circuit (2) connects the line to the office line (13) by the office line interface circuit (71), and further connects the line to the office line (13) via the office line interface circuit (71).
1 through the terminal interface circuit (3).
The button telephone (1) and the office line 112 are connected for a call.

On the other hand, the control circuit (to) each terminal interface circuit (31, (41, etc.) is connected to each button telephone (1),
(A data signal is sent to an LED (not shown) for displaying a used office line corresponding to office line 0, such as 21, to indicate that a call is in progress.

Third, think about the ending. For example, a button telephone (
When terminal 1) ends a call using the central office line ALL and performs an on-hook operation, a data signal indicating this operation is sent to control circuit 2 via terminal interface circuit (3). The control circuit (2) receives this signal and first disconnects the line connection with the station @all at the station line interface circuit (6) and disconnects the connection at the cross point (5).

On the other hand, the control circuit ■ is for each button telephone (1), <2
), etc. The call display of the LBD for indicating the station line in use, which is not designed, corresponding to the station line aυ, etc.
A data signal for turning off the RD is sent out via each terminal interface circuit (3), (4, etc.).

Next, the operation of the control circuit (to) of the control means (8) will be explained. FIG. 3 is an example of an operation flowchart regarding reading of operational data of the control circuit.

First, after the button telephone device is powered on and an initialization operation is performed, if there is a control request input from the button telephone or central office line, the input operation, that is, reading the control request input signal from the button telephone or central office line. An action is taken. Here, the control request input signal is, for example, a selection signal input via a central office line, a call termination request signal input from a key telephone, or the like. Next, it is determined whether or not there is a signal output from the timer circuit CLI at predetermined time intervals, and if there is an output signal, the operational data set in the setting switch circuit (9) is binary encoded as described above and stored in the memory Q11. Store in. Then, the result of the previous input operation is checked, and if there is an input, call processing, that is, incoming call processing, etc. is performed, and if there is no input, the input operation is repeated again. Therefore, the operational data set each time is updated and read based on the output signal of the timer circuit Q□, so even if the operational data setting of the setting switch circuit (9) is changed while the button telephone device is operating, the operation will continue. There is no problem.

FIG. 4 is another example of an operation flowchart relating to the reading of operational data of the control circuit (2).

In this example, the key telephone device is first powered on, an initialization operation is performed, and then an input operation is performed. Next, the result of this input operation is checked, and if there is an input, call processing is performed, and the input operation is repeated. Check the input operation results, and if there is no input, the timer circuit (1
Based on the output signal of the memory C! After storing it in υ, repeat the input operation again. 'Gatatsu [,
As described above, even if the setting of the operational data of the setting switch circuit (9) is changed while the button telephone device is in operation, there is no problem with the operation. Furthermore, in this way, if there is an input operation,
In other words, when there is an operating load on the key telephone device, updating and reading of operational data is in a waiting state, so that more efficient operation can be performed.

As explained above, according to the present invention, the operational data set in the setting switch circuit is periodically updated and read in addition to the initialization operation, so that the operational data settings can be changed even while the key telephone device is operating. Does not interfere with operation. In addition, the present invention eliminates the need to read operational data required for each call processing from the setting switch circuit, so that efficient operation can be achieved even when there are many inputs from key telephones and central office lines and the operating load on the control means is large. can be done.
