Furthermore, other service functions can be realized by pressing another selection switch 53 corresponding to the function similarly shown on the display section 52.

Problems to be Solved by the Invention However, with the conventional display and selection switch, for example, if the interrupt function is selected from the additional service function display during communication, does it actually work even if the interrupt function is selected again? However, there was a problem in that the operator was unable to make a decision at a glance because the interruption display was still displayed.

In this case, it is not a very difficult decision as it is related to the simplest function and operation of interruption, but if the terminal has multiple states and multiple functions can be realized at the same time, the displayed function It has been difficult to determine at a glance which functions are actually effective.

The present invention solves these conventional problems,
It is an object of the present invention to provide an operation display device that allows the display of telephone functions and additional service functions in ISDN to be determined at a glance.

Means for Solving the Problems In order to achieve the above object, the present invention includes a display means, an event I/judgment means for determining the state of its own terminal, and a service function of the terminal that operates depending on the state of its own terminal. It is provided with a service determining means for determining whether or not the service is available, and a means for lighting an operation switch corresponding to the service displayed on the display means.

Effect of the Invention With the above configuration, the present invention can instantly determine whether various service functions that are displayed simultaneously in various operating states of the terminal can be operated by checking the lighting of the operation switch, thereby preventing erroneous operations. It is possible to improve sexual performance.

Perform with 0FF. Reference numeral 3 denotes a selection switch operation control unit consisting of a key scan control unit 3a and a physical switch unit 3b that determine which selection switch 2 has been pressed, and when a physical switch is pressed, a corresponding interrupt is generated. The event occurs and is notified to the event interrupt control unit 5. Reference numeral 4 denotes an MPU which, based on event interrupt information from the event interrupt control unit 5, notifies the event determination unit 6 of an event determination request and displays the determination result of the event determination unit 6 and the determination result of the service determination unit 7 on the display 1. and notifies the selection switch 2. The event interrupt control section 5 detects an event generated from the selection switch operation control section 3, the handset 10, and the monitor switch 11, and notifies the MPU 4 of the interrupt. The event determination unit 6 performs event determination based on instructions from the MPU 4 and notifies the service determination unit 7 of the determination information. The service determining unit 7 determines an effective service function based on the information from the event determining unit 6 and notifies the MPU 4 of the valid service function. The control bus 8 conveys control information for each section 1 to 7, and the communication circuit 9
0N10FF for transmitting and receiving calls on the handset 10
The communication path is controlled by 0N10FF of the monitor switch 11 which is in a hook and dial input state.

FIG. 2 is a block diagram showing the operation in one embodiment of the present invention. In FIG. 2, numeral 21 indicates event management information in an idle state, and indicates a handset OFF hook event, a monitor switch ON event, an incoming call notification event, and a system setting event. 22 indicates a state in which an OFF hook event has occurred, and when the OFF hook event 22 occurs, the event table management information 23 is referred to. As a result of the reference, event table management information 23
If the system does not shift to one of the two states, system settings, it is determined that the other state is dial input in progress, and the system shifts from the initial idle state to the dial input in progress display 24. . When this dial input state is entered, the next service function management information 25 is referred to to determine the service function in that state, and in this case, the dial notification function and subaddress notification function are determined and displayed. Next, the selection switch management information 26 is
Turning on and off of the selection switch is managed with reference to the setting service management information 27. In the setting service management information 27, "with dial notification" and "with subaddress notification" have already been set, so the selection switch management information 26 has two functions: "dial notification function" and "subaddress notification function". The selection switch corresponding to is enabled, the LED of the corresponding selection switch is turned on, and the selection switch lighting instruction 28 is issued.

In this manner, in the dual embodiment, an interrupt is notified to the event interrupt controller 5 via the control bus 8 by hooking the handset 10 shown in FIG.
An interrupt is generated in the MPU 4 to request the event determination section 6 to determine the event type. On the other hand, the event determination unit 6 determines the OFF hook state 22 based on the event management information 21 shown in FIG. Perform middle display 2/I. In addition, in order to determine the service function in the dialing in progress state, the event determining section 6 notifies the service determining section 7 of the information on the dialing in progress display 24 to request determination of the service function.

The service determination unit 7 refers to the service function management information 25 and displays the manually entered information on the display 1 as a service that can be provided in the dial input state, and also refers to the setting service management information 27 to Selection switch operation control unit 3 only for set service functions
A selection switch lighting display 28 is performed by lighting up the LED of the selection switch 2 corresponding to the service function displayed on the display 1.

Next, referring to FIG. 3 and FIG. 4, we will show the specific configuration of the display section of this embodiment, the event determination when the monitor switch is turned on, and the fact that the dial notification function is effective from the determination result.
