Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key telephone system, and more particularly to a key telephone system in which shortened data stored in a key telephone terminal is managed by a main control unit of a master control device.

[0002]

2. Description of the Related Art Generally, in a key telephone system, abbreviated data of a speed dial signal is set from a key telephone terminal to a main control unit of a master unit, and the shortened data is set at the time of this shortening operation. The data is read to make an internal or external call.

However, according to this setting method, when the key telephone terminal is moved or the user changes seats, the speed dial operation cannot be performed unless the speed dial setting is performed again from the destination button telephone terminal. was there.

Therefore, in order to solve this problem, there is also a method of directly setting the shortened data of the shortened dial signal in the key telephone terminal.

However, this method has a problem that the specification cannot be changed because the shortened sequence of the key telephone terminal is determined by the mask ROM or the like.

In order to solve the above problem, the present invention provides a key telephone system in which the shortening sequence can be changed and the key telephone terminal does not need to be reset even if the key telephone terminal is moved.

[0007]

According to the present invention, in a button telephone system connected to a master control device and provided with a plurality of button telephone terminals and an outside line, the shortened data is written and read in the button telephone terminals. A key telephone system provided with a storage unit and a main control unit which is provided in the master control device and manages writing and reading of shortened data stored in the storage unit.

[0008]

The shortened data of the shortened dial signal is sent from the key telephone terminal to the main control unit of the main unit, and this shortened data is sent again to the storage unit of the key telephone terminal to perform storage setting.

At the time of operating the speed dial, the shortcut data is sent from the key telephone terminal to the main control unit of the main device. Based on this shortened data, the main control unit performs management such as reading the shortened data set in the storage unit of the key telephone terminal and performs a speed dial operation for an extension call and an outside call.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the button telephone system of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a block diagram showing an outline of the key telephone system of the present invention. The key telephone system is provided with a main unit 10. This main unit 10 has a CP
Main control unit 11 having U, ROM, RAM, etc., time switch 12 for connection control, plural terminal cards 1
, 13n, a plurality of outside line cards 14a, ..., 14
n is provided, and these are switched to the bus 15 and controlled to perform extension call control and outside call control.

, 16n are respectively connected to the plurality of terminal cards 13a, ..., 13n, and outer lines 17a, ..., 17n are connected to the plurality of outside line cards 14a ,. , Extension calls,
An outside line call is made.

, 16n, for example, the key telephone terminal 16a, is provided with a transmission section 18a connected to the terminal card 13a, and transmits and receives a call signal and a control signal. A speech network 19a, a data control unit 20a and a storage control unit 21a are connected to the transmission unit 18a.

The speech network 19a is provided with a handset 22a for transmitting / receiving a call signal, and the data control unit 20a is connected to a decoder unit 23a and a key scanning unit 24a for transmitting / receiving a control signal. A non-volatile storage unit 25a is connected to the storage control unit 21a to write or read shortened data or the like.

The LED driver 26 is provided in the decoder section 22a.
The LED 27a is connected via a, and the call status and the like are displayed. A keypad 28a and a function key 29a are connected to the key scanning unit 24a so as to receive a key signal.

In such a key telephone system,
First, the case of setting the shortened data of the shortened dial signal in the key telephone terminal 16a will be described.

Keypad 28 of the button telephone terminal 16a
a and the function key 29a are pressed, and shortened data of the setting signal, the address signal, the shortened data signal, and the registered signal are sent to the main unit via the key scan unit 24a, the data control unit 20a, and the transmission unit 18a as shown in FIG. Sent to 10.

In the main unit 10, the terminal card 13a, the bus 1
It is sent to the RAM of the main control unit 11 via 5 and is temporarily stored.

This abbreviated data is the key telephone terminal 16a.
When the shortening operation is completed, the shortened data such as the write command signal, the address signal, the length signal, the shortened data signal, and the end command signal are stored in the temporarily stored RAM of the bus 15, the terminal card 13a, and the key telephone terminal 16a. It is transferred to the storage controller 21a via the transmitter 17a.

The transferred control unit 2 stores the transferred shortened data.
When the 1a is received, as shown in FIG. 5, the write setting is performed at a predetermined position of the storage unit 25a.

In order to perform a speed dial operation using the speed data thus written, the speed dial operation is performed as shown in FIG.

The keypad 28 of the button telephone terminal 16a
When a and the function key 29a are pressed, a shortened address signal is sent to the main device 10 via the key scan unit 24a, the data control unit 20a, and the transmission unit 18a.

When the main unit 10 receives this shortened address signal, it is sent to the main control unit 11 via the terminal card 13a and the bus 15. The main control unit 11 has a CPU,
A read data signal such as a command signal, an address signal, or a length signal is sent to the key telephone terminal 16a by arithmetic control of the ROM or the like.

This read data signal is transmitted to the transmission section 18a,
Shortened data such as a read command signal, an address signal, a length signal, a shortened data signal, an end command signal, etc., is sent to the storage unit 25a via the storage control unit 21a.

The shortened data is called from the storage control unit 21a and the transmission unit 18a to the extension line and the extension line via the terminal card 13a, the time switch 12 and the like, and the extension call and the extension call are performed.

As described above, according to the key telephone system of the present invention, even if the key telephone terminal is moved, the abbreviated data is directly read and managed from the key telephone terminal to which the key telephone terminal is transferred, and it is not necessary to change the setting of the speed dial.
