The present invention relates to a communication technology by a key phone main device, and when the key phone main devices separated locally are connected by a dedicated line, a key phone which automatically transmits a corresponding dedicated line call code when calling an extension of another key phone main device. The present invention relates to a method for automatically transmitting a dedicated line call code of a host device.

In general, when a business of one company is divided into several regions, in order to make a call easily inside the company, a dedicated line board is attached to a key phone main unit installed in each business and connected to each other through each dedicated line board. At this time, basically one dedicated line board is to control up to six dedicated lines.

As described above, for example, the principle of connecting a plurality of key phone main apparatuses to each other through a dedicated line board mounted on each of them may be represented as a first diagram.

That is, the dedicated line board having six dedicated lines is mounted in the key phone main unit installed in each region, and these dedicated lines are connected to the dedicated line board of each key phone main unit. Here, when one key phone main unit has six dedicated lines and is connected to several other key phone main units, the number of dedicated lines to be connected is divided according to the call volume. That is, when the call volume is the most between the key phone main device A and the key phone main device B, it is possible to set more than the number of dedicated lines connected to other key phone main devices. In addition, the dedicated line board may be expanded according to the number of key phone main devices connected thereto.

To describe in more detail, reference is made to FIG. 2 showing a connection state between the dedicated line board mounted in the key phone main device and the key phone main device.

The key phone main unit 10 includes a central control unit 11, a main memory unit 12, a switching circuit unit 13, a switching memory unit 14 and a tone signal circuit unit 15, and is connected to the key phone main unit 10. The internal terminals 20A and 20N are composed of control sections 21A and 21B, switching circuit sections 22A and 22B, and speaker circuit sections 23A and 23B. In addition, the dedicated line board 30 for connecting each key phone main unit with a dedicated line includes a control unit 31, a switching circuit unit 32, and a control memory unit 33. Here, the key phone main unit 10 and the internal terminal 20A, 20N are connected through the main unit connection unit 24A, 24B of the internal terminal 16 and the internal terminal 20A, 20B of the key phone main unit 10, respectively. The key phone main unit 10 and the dedicated line board 30 are connected to the key line main unit 10 of the key line main unit 10 and the main unit connecting unit 34 of the dedicated line board 30 to exchange data with each other.

The central control unit 11 of the key phone main unit 10 stores / retrieves necessary data in the main memory unit 12, and issues a command to the switching circuit unit 13 to establish a call path. Then, the switching circuit unit 13 stores / searches the voice switch information corresponding to the switching memory unit 14 so that the actual call is made. At this time, the main memory unit 12 includes a transmission dial memory so as to store the numbers pressed to be transmitted by the key phone main apparatus for a while and then transmit them through the tone transmission circuit unit 15. In addition, when dialing at an extension terminal 20A or 20B to communicate with an extension connected to another key phone main device through a dedicated line, the switching circuit unit 13 transmits the dialing data designated by the tone transmission circuit unit 15 to the dedicated line connection unit 17. Transfer to the dedicated line board (30) through. The dedicated line board 30 determines which keyphone main device is connected to the called number and sends a signal thereto. At this time, in order for the extension of the keyphone main unit to make a call through each dedicated line, the extension lines of the keyphone main unit must be set to each dedicated line in order for the extension of the keyphone main unit to make a call through each dedicated line. do. That is, if there are 10 CO lines connected to one key phone main device, 5 of them are used for general call, and the remaining 5 lines are dedicated CO lines. For example, the call with the extension terminal of the key phone main unit connected to the dedicated line 1 and 2 is to be made through the CO line 2, and the call through the dedicated line 3 to the CO line 3. Thus, when making an extension call through a leased line, it is necessary to know the leased line call code (call code of the key phone main unit connected to the leased line), the CO line group number occupied by the leased line, and the extension number of the extension terminal to be called. .

That is, dialing should be dialed as shown in FIG. 3, which is a dialing operation when the extension 100 of the keyphone main device B is to be called from the extension 100 of the keyphone main device A.

First, the handset is off-hook in order to call the extension 200 of the keyphone main device B from the extension 100 of the keyphone main device A (step S1). Then, the main line designated to the dedicated line connected to the key phone main device B is occupied (step S2). When the leased line call code, for example, the leased line call code of the key phone main device B is '887', '887' is dialed sequentially (steps S3 to S5). Then, the extension number '200' is dialed (steps S6 to S8). The key phone main device B receives the dial data and applies a ring to the station 200 (step S9).

As described above, each time a dedicated line is used, the leased line must be occupied, and a dedicated line call code must be dialed in advance of the actual extension number, and the procedure is complicated. In particular, when several key phone main units are connected by a dedicated line. The inconvenience of having to memorize the dedicated line call code of each key phone main device one by one.

The present invention is to solve this problem, it is an object of the present invention to provide a method for automatically occupying the leased line and leased line call code when using the leased line in the key phone main unit connected by a leased line.

Automatic line call code transmission method in the present invention key phone main unit for achieving the above object is stored in the main memory unit of the key phone main unit, in the system programmable key phone telephone connected to the key phone main unit, by pressing the dedicated line call code setting mode button mode Converting the state to a dedicated line call code mode state; A second step of setting a record to store a dedicated line call code; A third step of selecting an extension start number of a counterpart key phone host device connected by a dedicated line; A fourth step of storing the extension start number by pressing a shortcut button; A fifth step of pressing the call code of the other party's key phone host device; A sixth step of pressing the shortcut button to store the call code; A seventh step of pressing a CO line group number to be used as a dedicated line; Including the eighth step of storing the CO line group number by pressing the shortcut button to repeat the eighth step in the second step.

In this way, when only the other party's extension start number stored in the fourth step is dialed, the station number designated as the dedicated line, the dedicated line call code, and the extension start number are automatically dialed, and the user is called by pressing only the next number of the extension start number.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

4 is a flowchart illustrating an operation of programming a dedicated line call code automatic transmission method in the present invention.

In general, a key phone telephone whose extension number starts first among the extension terminals connected to the key phone main device among the extension terminals connected to the key phone main device is capable of system programming.

In other words, if you press a button on the system programmable key phone, the program will be memorized in the main memory of the key phone main device.

In the system-programmable key-phone telephone, the procedure for programming the key-phone host to automatically transmit the dedicated line call code is to first press the corresponding mode button to change to the dedicated line call code setting mode (step T1). Set a record to store the call code (step T2), and press the extension start number of the other party's key phone main unit connected by a dedicated line (step T3). Then, the designated shortcut button is pressed in order to save and end the sound recording step T3 (step T4). At this time, the key-phone main apparatus stores the start number of the six-extension extension in the record specified in step T2. Then, the call code number of the other party's key phone main device is pressed in turn (step T5), and this button is also pressed to save while ending (step T6). After the step T6, press the CO line group number to use the dedicated line (step T7), and press the shortcut button to save and end (step T8). At this time, if another call code is to be stored in the next record number, the above steps (T2 to T8) may be repeated.

For example, the above operations will be described.

Here, the shortcut button used for storing and terminating the data is referred to as '*', for example.

If you change the mode status to the call code setting mode in the key phone for system programming, and you want to store in record 1 for the key phone main device whose extension number starts with '2', call key '887', first record Press '1' to set, then press '2'. Press '*' to store '2' in Record 1 and press call code '887'. Accordingly, press '*' to save. Then, select the CO line group number '3' used as a dedicated line and store it as '*'.

As a result, the button pressed by the user for programming is '1-2-*-887-*-3- *'.

However, when actually performed in the key phone main device it operates in the order of '3-887-2'. That is, after occupying the trunk line, the private line call code and the extension start number are transmitted. At this time, in order for the user to operate the key phone main device as the program through a dedicated line, the user only needs to input '2' stored as the extension start number.

The execution operation such as the sound will be described in more detail with reference to FIG.

The telephone receiver is off-hook in order to call the extension 200 of the keyphone main device B at the extension 100 of the keyphone main device A (step P1). Then, dial '2' is pressed (step P2). At this time. In the key-phone main device A, it is determined whether or not the currently input number is the dedicated line extension number start code (step P3) or otherwise, it is processed by referring to the internal code table (step P4). If it is corrected in step P3, it occupies the trunk line used as the dedicated line stored in memory, and stores and sends the dedicated line call code '887' and the user input code '2' to the transmission dial memory (step P5). That is, '8872' is stored in the delivery dial memory. Then, the user presses in sequence from the second digit to the last digit of the extension to be called (step P6) (step P7). At this time, the numbers stored in the transmission dial memory are '88720' and '887200'. The call numbers stored in the transmission dial memory are transmitted to the keyphone main device B in turn through the tone transmission circuit of the keyphone main device A (8-8-7-2-0-0), and the dials in the dial memory in the When the transmission of the information is completed, the keypad main unit B applies a ring to its extension 200 to make a call (step P8).

As long as you know the extension number system and the dedicated line call code of each key phone main device connected by a dedicated line as described above, the user can program it directly. The main device shall automatically transmit the occupation and call code of the leased line.

As described above, according to the present invention, a solution of a complicated procedure of dialing a dedicated line call code prior to occupying the leased line and the actual extension number every time the leased line is used, as well as a case where several key phone main units are connected by a leased line It is very convenient to use only the extension number when calling the extension of the other key phone main unit if the input is input to the system program when the key phone main unit is installed without having to remember the dedicated line call code of each key phone main unit.
