Description

[Detailed description of the invention] [Technical field to which the invention pertains] The present invention provides a button telephone device that can accommodate both a telephone office subscriber line (office line) and a private branch exchange subscriber line (PBX extension line). Regarding. In particular, the present invention relates to a button telephone device that enables automatic dialing when making a speed dial call, regardless of whether the line to be called is a central office line or a PBX extension line.

[Description of prior art]

In a button telephone device with a built-in speed dial function, when the speed dial button is operated, the contents stored in the memory in advance are read out.
It is configured to be sent as a dial signal to the line. When such a device accommodates only a central office line or a PBX extension line, dialing signals for speed dialing can be uniformly set, but in recent years,
With the spread of dial-in services, it has become common for a single button telephone device to accommodate both a central office line and a PBX extension line.

In such cases, if you set the speed dial dial signal in the form of a PBX extension,
When dialing an outside line, the first digit always includes an outside line dialing code (for example, "0"). Therefore, when a central office line is selected and a call is made from this speed dial, an outside line call code is issued even though it is not required in the first place, resulting in an erroneous connection. For this reason, with conventional devices, it is necessary to determine in advance whether the speed dial is a central office line or a PBX extension, and this has the drawback of requiring users to be aware of this each time they make a call.

[Purpose of the invention]

The present invention improves this and
A button that allows you to make a speed dial call with the same operation, regardless of whether the selected subscriber line is a central office line or a PBX extension, when both PBX extensions are accommodated. The purpose is to provide telephone equipment.

[Features of the invention]

In the present invention, the device automatically determines whether the telephone line to be automatically dialed by speed dialing is a central office line or a PBX extension, and if it is a central office line, the subscriber's telephone number is obtained by removing the first digit PBX outside line dialing code. The feature is that it has a function to send out only as an automatic dialing signal.

That is, the present invention has a speed dial function,
Line type setting for setting whether each accommodated line is a central office line or a PBX internal line in an electronic button telephone device that accommodates both a central office line and a PBX extension line and can arbitrarily select and dial either line from the button telephone of the terminal. a speed dial memory which is equipped with a circuit and can further store a PBX outside call code in the first digit of the speed dial, and a control unit which controls the line type setting circuit, the speed dial memory and each part of the device;
Determine whether the telephone line to make the speed dial call is a central office line or a PBX extension, and if it is a central office line, enter the first digit.
The present invention is characterized in that it includes means for removing the PBX outside call code and dialing only the stored subscriber telephone number.

[Explanation based on examples]

Next, embodiments of the present invention will be described with reference to the drawings.

The figure is a block diagram of an apparatus according to an embodiment of the present invention.

In the figure, the device of the present invention has a speed dial memory 1
and a line type setting circuit 2, which are connected to a control section 3 including a microprocessor. On the other hand, the office line and PBX extension line are connected to the office line interface 4, and the telephone of this button telephone device is connected to the telephone interface 5.
The office line interface 4 and the telephone interface 5 are configured so that they can be exchanged and connected using a known communication path switch matrix 6, and this communication path switch matrix 6 is controlled by the control section 3.

Here, the central office line interface 4 includes the central office line and
Both PBX extensions are accommodated. The speed dial memory 1 also includes subscriber numbers selected from the central office line, assuming that the call is made from the PBX extension.
Add the PBX outside line call code "0" to the first digit and store it.

One of the features of the device of the present invention is the line type setting circuit 2, which determines whether the accommodated line of the central office line interface 4 is a central office line according to its terminal number.
Set in advance whether it is a PBX extension using the strap line.

Furthermore, when making a speed dial call, the program in the control unit 3 identifies whether the selected line is a central office line or a PBX extension line based on the contents of the line type setting circuit 2, and if the PBX If it is an extension line, read the contents of memory 1 and send it to the line as is; if it is a central office line, read the contents of memory 1, omit the first digit, and send it to the line from the second digit. It is composed of

Therefore, to explain the operation when making a speed dial call, firstly, when the operator of the button telephone performs a line capture operation, the control unit 3 immediately checks the line type setting circuit 2 and selects the line type selected at that time. Determine whether the line is a central office line or a PBX extension line. Next, when a speed dial origination operation is performed, the control unit 3 determines the line as described above, and if the selected line is a central office line, the first one in the speed dial memory 1 is
The central office line interface 4 is controlled so as to omit the PBX outside line calling code in the digit and send the subscriber's telephone number in the second and subsequent digits to the central office line.

Also, if the above line discrimination result is a PBX extension, it is stored in speed dial memory 1.
The central office line interface 4 is controlled so as to send the PBX outside line calling code and the subscriber's telephone number over all digits to the line.

[Explanation of effects]

As explained above, according to the present invention, whether a central office line or a PBX extension line is selected,
A device is obtained in which the operator can uniformly perform speed dial operations. This allows you to effectively use the speed dial function, and
Misconnections can be eliminated.

Claims (1)

[Scope of Claims] 1. A central office line and a PBX extension line are configured to be accommodated as a line, and include a memory for storing dial signals, and a memory for reading the stored contents of the memory and transmitting it to the line by speed dial operation. The button telephone device is equipped with a line type setting circuit for setting whether the accommodated line is a central office line or a PBX extension line, and the control unit Is the line you received a central office line?
means for identifying whether it is a PBX extension by comparing it with the line type setting circuit; and when it is determined by this means that a central office line has been selected, the first digit of the dial signal read from the memory; and a means for transmitting data to the line without using the telephone line.
