To end the communication, the user presses the disconnect button (depending on the device) on the keypad 4, and the same is done.

[Problem to be solved by the invention]

Since the conventional l5DN terminal adapter is configured as described above, some kind of user access control for the keypad 4 connected to the l5DN terminal adapter main body 1 is required each time to start and end communication. Generally speaking, access between the host combinator and terminal f2 in an office is often to a fixed destination, and the connection time period is also often fixed, but even in such cases, There was a problem in that the user had to operate the keypad 4 or the like each time to connect/disconnect a call.

This invention was made to solve the above-mentioned problems.
l5DN that can automatically connect and disconnect calls based on disconnection time, call connection destination, transmission ability, etc.
The purpose is to obtain a terminal adapter.

[Means to solve the problem]

The l5DN terminal adapter according to the present invention creates a time control table based on call connection/disconnection times, call connection destinations, and transmission capabilities input into the key input analysis section as key input information, and manages time. The system is equipped with a time control unit that performs call control based on a time control table.

[Effect]

The time control unit in this invention creates a time control table in advance based on key input information input by the user such as call connection/disconnection time, call connection destination, transmission ability, etc., and manages time. By performing call control based on the created time control table, an I5DN terminal adapter that can automatically connect and disconnect a call is realized.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, 1 is the l5DN terminal adapter body, 2 is the terminal device, 3 is the l5DN basic interface line,
4 is a keypad, 5 is a display device, 11 is a terminal interface section, 12 is a line interface section, 13 is a layer control section, 14 is a device management section, 15 is a key input analysis section, 1
6 is a channel selection section, 17 is a display control section, 21 is a layer 1 control section, 22 is a layer 2 control section, and 23 is a layer 3 control section, which are the same as the conventional ones with the same reference numerals in FIG. Otherwise, the detailed explanation will be omitted since it is a considerable part.

Further, 18 is the call connection/disconnection time input by the user into the key input analysis unit 15 by operating the keypad 4;
A time control table is created and saved in advance based on key input information such as the destination of the call connection and transmission capacity.
It is a time control unit that further manages time and executes call control using the created time control table. This time control section 18 is connected to the device management section 14 and the key input analysis section 15 in the I5DN terminal adapter main body 1.

Next, the operation will be explained. The user first starts up the I5DN terminal adapter main body 1, and then operates the keypad 4 to input call connection/disconnection time, call connection destination, and transmission capability as key input information. The input key input information is sent from the key input analysis section 15 to the v display control section 17 and displayed on the display device 5. The user inputs the key input information while checking the display on the display device 5. The key input information input in this way is analyzed by the key input analysis section 15 and passed to the time control section 18.

The time control unit 18 creates and stores a time control table based on the received key input information. In this time control table, the above-mentioned information is recorded for each destination to which an automatic call is desired.

FIG. 2 is an explanatory diagram showing an example of a time control table created and saved by this time control section 18. In the figure, 30 is this time control table, where the start time based on the call connection time of the 3Nd input key input information is recorded, and 32 is the area where the end time based on the call disconnection time is recorded. , 33 is an area in which a destination number based on the destination of the call connection is recorded, and 34 is an area in which, for example, bearer information, which is also based on transmission capability, is recorded.

Such a time control table 30 is created in advance, and the time control unit 1B that has saved it independently performs time management. As a result, if the start time recorded in any of the areas 31 of the time control table 30 matches the current time, the time control section 18 sends a call request to the device management section 14 . At that time, the time control unit 18
Furthermore, from the areas 32 and 34 corresponding to the area 31 from which the start time was read, the corresponding destination number and bearer information are also read out at the same time and passed to the device management section 14.

The subsequent signal flow is the same as in the conventional case.

That is, the device management section 14 that has received and received this information checks the availability of resources and sends a transmission request to the layer control section 13, and the layer control section 13 executes control of each layer. At this time, a protocol control signal is exchanged between the line interface unit 12 and the exchange, and a channel is selected.

The device management unit 14 sends the signal of the channel selected in this way to the channel selection unit 16.
further connects the channel to the terminal device 2.

Further, as a result of time management, if it is detected that the end time recorded in any of the areas 32 of the time control table 30 matches the current time, the time-side division external unit 18 sends a disconnection request to the device management unit 14. The same is done by sending. The signal path at this time is also the same as in the conventional case.

Note that in the above embodiment, the start time of the time control table,
Although we have shown a method that records only a simple time as the end time, it is possible to expand the concept of time to specify the year, month, day, repeat pattern (repeat the same pattern every day), and even , Saturday, Sunday, holiday, etc. may be specified, thereby further improving convenience.

Further, in the above embodiment, a case was explained in which the call is disconnected by specifying the end time, but it may also be specified by communication time (for example, ×X hours, etc.), and the same effect as in the above embodiment is achieved. .

〔Effect of the invention〕

As described above, according to the present invention, a time control table is created in advance based on key input information input by the user, time is managed, and call control is performed based on the created time control table. Now that I've configured it to run,
When access is often between a host computer and a terminal device in an office, and the connection time is often fixed, it is possible to eliminate the need for user actions each time a call is connected or disconnected. This has the effect of providing an I5DN terminal adapter that can automatically connect and disconnect calls based on the contents of a preset time control table.
