DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal adapter, a telephone, a facsimile, a video telephone, and the like.
The present invention relates to an ISDN communication processing device that can be connected to an SDN line.

[0002]

2. Description of the Related Art In a general ISDN communication processing device, as a method of detecting the end of dial input, a method of inputting a "call" key or a "#" key at the end of dial input,
Dialing interval is measured by using a timer (hereinafter referred to as "inter-digit timer"), and it is determined that dialing is completed by a timeout. Processing is in progress.

Hereinafter, a conventional ISDN communication processing device will be described with reference to FIGS. 4 and 5. FIG. FIG. 4 is a functional block diagram of a conventional ISDN communication processing device. In addition, conventional ISD
The N communication processing unit comprises 21 to 25 described later, 21 is a network interface unit for transmitting / receiving to / from an ISDN line, 22 is a call control unit for managing outgoing / incoming calls and disconnection, and 23 is an interdigit timer. A timer control unit for starting and stopping the dialing; a dial control unit for storing and managing dial information input by a user;
Is a terminal interface section for directly transmitting and receiving information to and from a non-ISDN terminal (telephone or the like) described later. 26 is non-I
The SDN terminal 27 is an ISDN line unit.

[0004] The operation of the ISDN communication processing apparatus configured as described above will be described below. When making a call, the user inputs the communication partner number from the non-ISDN terminal 26. The input dial information is sequentially stored in the dial control unit 24 via the terminal interface unit 25. When the first dial (first digit) is input, the timer control unit 23 starts an inter-digit timer set to a predetermined time in advance, and when the next dial (second digit) is input, the first digit (second digit) is input. Stops the inter-digit timer started when dialing. This operation is sequentially repeated, and if the next dial is not input during the activation of the interdigit timer after the last dial input, it is regarded that dial input has been terminated due to the timeout of the interdigit timer, and is stored in the dial control unit 24. The dial information is sent to the ISDN line unit 27 via the call control unit 22 and the network interface unit 21.

FIG. 5 is a diagram showing a dial input when a seven-digit dial is input using a one-touch dial of a non-ISDN terminal 26 connected to a conventional ISDN communication processing apparatus, and an inter-digit timer started at that time. It is a figure showing a relation.

In FIG. 5, when a seven-digit dial is input by a one-touch dial, the dial is input at a constant interval in a considerably short time. When the first digit dialed is input timer control unit 23 operates the interdigit timer set to a time T _D, and the second digit of the dial is input is operated during the dialing of the first digit digit The inter-digit timer is cut off and the inter-digit timer is activated again. These dial input, operation and disconnection of the interdigit timer is automatically performed after the last 7 digit dialed is entered, if T _D time after inter-digit timer is cut dialed controller 2
4 sets a call to the call control unit 22.

Incidentally, as a conventional example different from the above, when the user inputs a "call" key (not shown) provided on the ISDN communication processing device or the non-ISDN terminal 26, the dialing is regarded as being completed, and the dialing is terminated. A method of sending dial information stored in the control unit 24 to the ISDN line unit 27 via the call control unit 22 and the network interface unit 21 has also been adopted.

[0008]

However, the conventional configuration has the following problems. In other words, in the method in which the user inputs the end of the dialing by using the "call" key or the "#" key, the "
In some cases, the user forgets to input the "Call" key or the "#" key, etc. Further, some telephones cannot have the "Call" key or cannot send information such as the "#" key as a substitute ( For example, there is a rotary dial type telephone (hereinafter, referred to as "DP type telephone"), so it may not be adopted in some cases.

In the method of judging the end of dial input by using the interdigit timer, if the interval setting of the interdigit timer is constant, if an excessively large interval is set during dial input, the interdigit timer is activated and again. In some cases, the user has to re-enter the number, or if each digit is entered at short intervals, the user has to wait for a while after the dialing is completed until the terminal is connected to the ISDN line.

Further, even if the ISDN communication processing device has a function of detecting the end of the dial input by a combination of the two methods of the "transmission" key and the inter-digit timer, the connected terminal moves away from the ISDN communication processing device. If the connection terminal is a DP-type telephone in a location where it is located, there is no other way than detecting the end of dialing using only the inter-digit timer. Therefore, even if the one-touch dial function of the DP telephone is used, the inter-digit timer is not used. There is a problem that the advantage of the one-touch dial function cannot be utilized because the call is not transmitted until the timeout occurs.

An object of the present invention is to provide an ISDN communication processing device in which the value of an inter-digit timer changes according to the speed at which a user inputs a dial.

[0012]

In order to achieve the above object, the present invention comprises an inter-digit timer value setting unit which determines a value of an inter-digit timer in accordance with a speed at which a user inputs a dial. It is.

[0013]

According to the present invention, n digits (n is a natural number) are provided by the above configuration.
When the dial must be input, the input time from the first digit to the k-th digit (k = 2, 3,..., N) is measured and processed, and the processed time is input to the k-th digit. By setting the interdigit timer setting time from the time, the interdigit timer setting value is changed according to the speed at which the user inputs a dial.

[0014]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a functional block diagram of an ISDN communication processing device according to an embodiment of the present invention.
Through 6.

In FIG. 1, reference numeral 1 denotes a network interface unit for transmitting / receiving to / from an ISDN, 2 a call control unit for managing outgoing / incoming calls and disconnection, etc., and 3 a user of a set value of an interdigit timer. The interdigit timer value setting section, which is determined in accordance with the speed at which the dial is input, a timer control section 4 for starting and stopping the interdigit timer, etc., and 5 stores and manages dial information inputted by the user. Dial control unit,
Reference numeral 6 denotes a terminal interface unit for directly transmitting and receiving information to and from a non-ISDN terminal (telephone or the like) described later. 7 is non-I

The dialer of the communication partner is input from the SDN terminal 7. Non-I
Dial information input from the SDN terminal 7 is sequentially stored in the dial control unit 5 via the terminal interface unit 6.

FIG. 2 is a diagram showing the relationship between the input dial and the set value of the inter-digit timer. In the figure, when a user attempts to input an n-digit dial from a non-ISDN terminal 7 such as a DP telephone, when the first digit is input, the inter-digit timer value setting unit 3 switches to a timer control unit. 4
Two orders of magnitude between the timer value T _D is notified, inter-digit timer is started. The timer value T _D between digits at this time is a preset default value.

At the same time as dialing of the second digit is

When the dial after the k-th digit is input, the inter-digit timer value setting unit 3 notifies the timer control unit 4 of the inter-digit timer value T, and the timer control unit 4 operates based on the information. Start the timer. The input dial information is stored in the dial control unit 5. If the user enters the last digit and there is no new dial input by the time T, the dial input is considered to be completed, and the dial information is transmitted from the dial control unit 5 via the call control unit 2 and the network interface unit 1. To the ISDN line section 8 for transmission.

Next, the operation when n = 7, k = 5, and m = 1 using a one-touch dial in this embodiment will be described in detail with reference to FIG. FIG. 3 shows a dial input when a 7-digit communication partner number is dialed using a one-touch dial of the non-ISDN terminal 7 connected to the ISDN communication processing device, and an inter-digit timer activated at that time. FIG. 6 is a diagram showing the relationship, and when a user inputs a first digit dial, a predetermined time T _D
During this period, the timer control unit 4 operates the inter-digit timer. At the same time the interdigit timer value setting unit 3 measures the time T ₁ of the column 1 of the input to the second digit of the input, and stores.

Further, when the dial of the second digit is input within the time T _D , the timer control unit 4 cuts off the inter-digit timer and activates the new inter-digit timer T _D. At the same time, from the input of the second digit,
Measuring the time T ₂ until the digit of input, and stores. Thereafter, the same operation is performed until the fifth digit is input.

When the fifth digit is input, the
The inter-digit timer that was activated when the digit was dialed is cut off, and the inter-digit timer value setting unit 3 calculates the new inter-digit timer operation time from the equation T = (T ₁ + T ₂ + T ₃ + T ₄ ) × 1. And sends it to the timer control unit 4. The timer control unit 4 activates the inter-digit timer for the time T at the same time that the value of T is calculated by inputting the fifth digit dial.

When the dial of the sixth digit is input within the time T, the interdigit timer operated when the dial of the fifth digit is input is cut off, and the interdigit timer is newly activated for the time T.

Finally, when the dial of the seventh digit is input within the time T, the interdigit timer that was operated when the dial of the sixth digit was input is cut off, and the interdigit timer is newly activated for the time T. Let it.

After that, if there is no new dial input, the dial control unit 5 sends the dial information via the call control unit 2 and the network interface unit 1 at the same time as the time T elapses.
It transmits to the line section 8.

As described above, when the fifth digit is quickly input, the inter-digit timer value T from the input of the fifth digit is normally T
_It becomes smaller than _{D, and the time} from the user inputting the last digit to making a call is faster, and a quick call can be made. Conversely, if the fifth digit is slowly input, the inter-digit timer value T from the input of the fifth digit is larger than the normal T _D , and
The dial after the first digit can be input slowly, and there is no need to confirm the dial in the middle of the input and the time-out occurs and the user must input again.

[0027]

As described above, according to the present invention, the set value of the inter-digit timer can be determined according to the speed at which the user inputs a dial, so that an appropriate length is set every time the user dials. The ISDN communication processing device capable of starting the interdigit timer and enabling simple and quick transmission can be provided.
