Abstract

PURPOSE:To improve the service of an exchange by providing two kinds of short and long pose monitoring devices to monitor the pose between dial digits. CONSTITUTION:When the handset of a telephone set 1 is hooked off, a central control device 3 detects this, starts the dial monitoring, and simultaneously, the monitoring is indicated to a long period and short period inter-digit pose monitoring devices 4 and 5. After the dial from the telephone set 1 is detected, the device 3 decides whether the dial is settled or not, and when it is settled, the telephone set of an opposite party is called, and when the response is detected, a call device 2 is controlled and two telephone sets are connected. When the dial is not settled, the monitoring timer of the devices 4 and 5 is reset. When the device 4 detects an inter-digit pose, the device 3 decides the erronious dial and a busy tone, etc., are sent to the telephone set 1.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a dial determination device used in, for example, a key telephone device or an exchange.

2. Description of the Related Art A conventional dial determination device for an electronic exchange will be explained with reference to FIG. 2. Reference numeral 101 represents a telephone set, and 102 represents a communication path.

A central control unit 103 monitors the status of the telephones 101, controls the communication path 102, and executes connection control between the telephones 101. 104 is an interdigit pause monitoring device that measures the time between dialed digits on the telephone 101 according to instructions from the central controller 103, and if there is no dialing for a certain period of time or more,
The central control device 103 is notified.

Next, the operation of the above conventional example will be explained. Telephone 101
When the handset is picked up, the central controller 103 detects this and starts dial monitoring.

At the same time, a monitoring instruction is given to the inter-digit pause monitoring device 104. After detecting a dial from the telephone 101, the central control unit 103 determines whether the dial has been confirmed, and if confirmed, calls the other party's telephone, and when a response is detected, controls the communication path 102 to call the two telephones. Connecting. If the dial is not determined, the interdigit pause monitoring device 10
Reset the monitoring timer in step 4. Inter-digit pause monitoring device 10
4 detects an interdigit pause, it notifies the central controller 103. If the dial is not confirmed when the inter-digit pause is detected, the central control unit 103 determines that the dial is an incorrect dial and sends a busy tone or the like to the telephone 101. If the dialing is confirmed by inter-digit Bose detection (for example, when there are extension numbers "2" and "211", dialing "2"
''), the telephone 101 of the determined party is called, and a call is established by the party's response.

Problems to be Solved by the Invention However, in the above conventional example, the extension number is "2".
In order to realize a dial plan that has the same dial at the beginning, such as R2111J and R2111J, the only way to judge the dial is to wait until the inter-digit pause is detected, so if the inter-digit pause time is increased, the dial judgment There is a problem in that it takes time to establish a connection, and conversely, if the pause time between digits is shortened, incorrect dialing will be detected too quickly during normal dialing, and if dialing a little slowly, incorrect dialing will occur. There was a problem with being judged.

Therefore, the present invention is intended to eliminate the drawbacks of the above-mentioned conventional example, and it is possible to quickly realize the dial determination between an extension number with a short number of digits and an extension number 2 function number having the same dial as the extension number at the beginning. Not only is this possible, but in the case of simple dials, even if the dial is turned slowly, it will not be judged as a false dial, and connection control will be faster, which will improve the serviceability of the exchange. The purpose of this invention is to provide a dial determination device that uses the following methods.

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems includes a communication path for forming calls between a plurality of telephones, and a communication path for forming calls between a plurality of telephones, and monitoring the status of the telephones. The pause monitoring device with long monitoring time is used to detect incorrect dialing, and the pause monitoring device with long monitoring time is used to detect incorrect dialing, and the pause monitoring device with short monitoring time is used to detect incorrect dialing. The pause monitoring device is configured to be used to distinguish two extension numbers and function numbers having the same dial number but different numbers of digits.

Operation According to the above-described configuration, when the handset of the telephone is picked up, the central control unit detects this and starts dial monitoring. At the same time, a monitoring instruction is given to the long and short interdigit pause monitoring device. When a dial from a telephone is detected, the central control device determines whether the dial has been confirmed, and if confirmed, calls the other party's telephone, and when a response is detected, controls the communication path and connects the two telephones. If the dial is not determined, reset the monitoring timer of the long/short interdigit pause monitoring device. When the long-term inter-digit pause monitoring device detects an inter-digit Bose, the central controller is notified. The central control unit determines that it is an incorrect dial and sends a busy tone etc. to the telephone. When the short-term inter-digit pause monitoring device detects an inter-digit Bose, it notifies the central controller. The central controller determines whether the dialing is confirmed by interdigit Bose, and if confirmed, calls the other party's telephone and waits for timeout notifications from the two call volumes in response. In this way, a pause monitoring device with a short monitoring time is used only for determining fast dialing, and a pause monitoring device with a long monitoring time is used only for determining incorrect dialing, thereby making it possible to quickly determine complex dialing plans. In addition, in the case of a simple dialing plan, even if a slow dial is made, it will not be judged as an incorrect dial, and efficient dialing judgment can be realized corresponding to various dialing plans.

EXAMPLE An example of the present invention will be described in detail below with reference to the drawings. In FIG. 1, 1 is a telephone, and 2 is a communication path for forming a call between the telephones 1 and 1. In FIG. Reference numeral 3 denotes a central control unit that monitors the status of the telephones 1, controls the communication path 2, and executes connection control between the telephones 1.

4 is a long-time inter-digit Bose monitoring device, and 5 is a short-time inter-digit pause monitoring device. The long-time inter-digit Bose monitoring device 4 is used to detect incorrect dialing, and the short-time inter-digit pause 5 is used for dial determination based on inter-digit Bose. That is, it is used to distinguish between extension numbers and function numbers that have the same dial number but different numbers of digits.

Next, the operation of the above embodiment will be explained. When the handset of the telephone 1 is picked up, the central control unit 3 detects this and starts dial monitoring. At the same time, interdigit pause monitoring device 4,
Instruct 5 to monitor. After detecting a dial from telephone 1, central control unit 3 determines whether the dial has been confirmed, and if confirmed, calls the other party's telephone, and if a response is detected, controls call path 2 to connect the two telephones. do. If the dial is not determined, the monitoring timers of the inter-digit pause monitoring devices 4 and 5 are reset. When the long-term inter-digit pause monitoring device 4 detects an inter-digit pause, it notifies the central control device 3. As a result, the central control device 3 determines that the dial is an incorrect dial, and sends a busy tone or the like to the telephone 1. When the short-time inter-digit pause monitoring device 5 detects an inter-digit pause, it notifies the central control device 3. As a result, the central controller 3 determines whether or not the dialing is confirmed during the pause between digits, and if confirmed, calls the other party's telephone 1, and when a response is detected, controls the communication path 2 to connect the two telephones. . If the dial is not determined, nothing is done and the system waits for the next dial or a timeout notification from the long-duration inter-digit pause monitoring device 4.

Effects of the Invention As is clear from the above description, the present invention provides an inter-digit pause monitoring device with a long monitoring time for determining incorrect dials, and an inter-digit pause monitoring device with a short monitoring time for quick dial determination. This not only makes it possible to quickly make complex dial judgments, but also prevents simple dials from being judged as incorrect dials even if the dial is rotated slowly. Accordingly, efficient dial judgment can be realized. Furthermore, since connection control becomes faster, the serviceability of the exchange can be improved. Furthermore, the inter-digit pause monitoring device is economical because it can be configured as desired by a program by providing only a basic timer.
