Description

The present invention relates to a control method of a telephone terminal in an electronic exchange.

[Conventional technology]

Conventionally, the control of a telephone terminal connected to an electronic exchange and operated is performed by a fixed program stored in the memory of the central control unit (CPU) of the electronic exchange.
This fixed program is configured so that it cannot be changed.

[Problems to be solved by the invention]

As described above, in the conventional control of the telephone terminal, the control program is the read-only memory (RO
It is stored in M) and always performs the set processing according to the conditions. In other words, it is impossible to change the program according to various states. Therefore, there is a problem that the buttons and lamps provided on the telephone terminal can always be used for a predetermined purpose, and the meaning of the buttons and lamps cannot be optimized according to the state of call processing.

[Means for solving problems]

The control system according to the present invention is connected to an electronic exchange, and in a telephone terminal provided with a CPU and a memory, a memory stores a plurality of terminal processing programs in addition to a terminal control program. Phone terminal CPU
Selects and loads one of multiple terminal processing programs as a selection program for the CPU of the electronic exchange,
On the other hand, the CPU of the electronic exchange has a random access memory (RAM) area for storing this selection program, and the central control unit of the electronic exchange controls the telephone terminal based on the selection program stored in the RAM area. It is characterized by doing so.

〔Example〕

 Next, the present invention will be described with reference to examples.

Referring to FIG. 1, a plurality of telephone terminals 1 are connected to the electronic exchange 2. The telephone terminal 1 includes a handset 11, an operation unit 12, a central control unit (CPU) 13, a main storage unit 14 and an interface 15, while the electronic exchange 2 has a switch 21, a central control unit 22 and a temporary storage unit 23. Is equipped with. The CPU 13 and the CPU 22 are connected via the bus line 3, while the switch 21 is connected to the interface 15.

As described above, the central control unit (CPU) 22 of the electronic exchange 2 is connected to the central control unit (CPU) 13 of the telephone terminal 1 in the bus type, and the CPU 3 communicates with each other by the bus line 3. . The CPU 13 of the telephone terminal 1 uploads the program read from the main storage device 14 to the temporary storage device (RAM) 23 via the CPU 22 of the electronic exchange 2. In addition to the normal terminal control program, the main storage device 14 stores a program group 14a uploaded according to the usage state of the telephone terminal 1. That is, in the main storage device 14, in addition to the terminal control program used when the central control device 13 controls the telephone terminal 1, the usage state of the telephone terminal 1 (for example, the button of the operation unit during call processing and A plurality of uploaded terminal processing programs are stored as a program group 14a according to the meaning of lamps and the like). In order to change the state of call processing (that is, the meaning of buttons and lamps on the operation unit), when the operation unit 12 including buttons, dial pad, switch, etc. is operated on the telephone terminal 1, the operation on the operation unit 12 is performed. Depending on the CP
U13 selects one terminal processing program (optimum terminal processing program) from the program group 14a as the selected terminal processing program, and the CP of the electronic exchange 2 via the bus line 3.
Send to U22. Then, the CPU 22 stores the received selected terminal processing program in the RAM 23. After that, the CPU of the electronic exchange 2
A selected terminal processing program 22 is stored in the RAM 23 and controls the corresponding telephone terminal 1. That is, the CPU 22 controls the telephone terminal 1 based on the selected terminal processing program when performing the call processing. As a result, the meanings of the buttons and lamps on the operation unit change.

〔The invention's effect〕

As described above, in the present invention, the electronic exchange is provided with the RAM area for storing programs, and the terminal processing program stored in the memory of the telephone terminal from the CPU of the telephone terminal is used as a selected terminal processing program as necessary. As appropriate
Since the CPU of the electronic exchange controls the telephone terminal based on this selected terminal processing program when it is loaded in the RAM area and the call processing is performed, the meaning of the buttons and lamps can be changed according to the call processing state. In addition, it is possible to provide unique operability for each telephone terminal.
