The present invention relates to an ISDN telephone system applied to an integrated service digital network (ISDN), in particular, after storing a telephone number of a designated subscriber and automatically repeating a voice call with the stored telephone number to perform a call test. Then it relates to a method of testing the call to display the results.

In general, the general information communication network is a technology that transmits high speed (160Kbps) digital data through the existing analog line. It is weaker in the line noise than the analog phone, so it is often conducted a periodic and continuous call test for a certain group of subscribers. Occurs.

FIG. 1 is a block diagram of a general ISDN telephone, and includes a keypad 20 for inputting a telephone number, a test frequency, and other necessary variables, and a telephone number and test number data to be tested from the keypad 20. An MPU 10 for receiving a voice call and controlling a voice call test, and a voice codec unit 12 for a tester to use for a monitor or converting various necessary signals from an analog voice signal to a digital signal, or converting a digital voice signal and a signal sound into an analog signal 12. ), The display unit 22 for displaying the telephone number and the angle variable and the call progress state input by the control of the MPU 10 and the telephone number and call progress state that are being progressed by the control of the MPU 10. Data port connection unit 14 converts the result of the call progress and the like to be connected to an external printer, and various voice information and calls digitized by the control of the MPU 10. A line connection unit 16 for converting a signal so as to connect a processing signal to an ISDN switching network, a memory 18 for storing a program for voice call testing, and a MPU 10 by detecting a hook on / off state of an ISDN telephone. It consists of the hook switch 24 applied with the following operation | movement, and performs the following operations (refer also to FIG. 2a).

First, in step 101, the MPU 10 checks whether a key signal is input from the keypad 20, and if the key signal is input, proceeds to step 102.

In step 102, the MPU 10 checks whether a set up key is input, performs another function if the setup key is not input, and proceeds to step 103 if the setup key is input. In step 103, the MPU 10 performs a setup process and returns to step 101. However, if the key signal is not input in step 101, the process proceeds to step 104 and the hook switch 24 is checked to see if it is hooked off (hook off). In step 105, the MPU 10 checks whether the hook switch 24 is hooked on, and returns to step 101 when the hook switch 24 is not hooked on, and proceeds to step 106 when the hook switch 24 is hooked on. In step 106, the MPU 10 checks whether the telephone is in use and returns to step 101 if it is not in use, and proceeds to step 107 if it is in use, and cuts the telephone line. In addition, if the hook is off in step 104, the process proceeds to step 108. The MPU 10 checks whether the call is in progress and proceeds to step 103 if it is busy. If the call is not in step 108, the process proceeds to step 109 and the MPU 10 inputs a phone number from the keypad 20 to transmit a setup message, and proceeds to step 110. In step 110, the MPU 10 checks whether there is a message reception response from the counterpart, and if there is a message reception response, the MPU 10 proceeds to step 111.

In step 111, the MPU 10 checks whether the other party is empty. If the other party is empty, the MPU 10 proceeds to step 112 to connect the telephone line. However, if the other party's call is not empty in step 111, the process proceeds to step 113 to transmit a busy tone.

The ISDN telephone is controlled as described above, and when an interrupt occurs, the ISDN telephone is controlled as shown in FIG. 2B.

That is, when an interrupt occurs, the MPU 10 checks whether a voice call is received through the line connection unit 16 in step 201, and proceeds to step 202 when the voice call is received. In step 202, the MPU 10 checks whether voice call reception is possible, and if voice call reception is possible, proceeds to step 203 to connect and return a call. However, if no voice call is received in step 201, the process proceeds to step 204. The MPU 10 checks whether or not the data call request is returned, and if not, returns to the data call request. In step 205, the MPU 10 checks whether it is in use and returns if it is in use. If not, the MPU 10 proceeds to step 206. In step 206, the MPU 10 performs a data call processing and returns.

The conventional ISDN telephone as described above has a cumbersome problem of repeatedly inputting the same telephone number each time to perform a call test.

Accordingly, an object of the present invention is to provide a call test method for inputting a subscriber number and a test frequency to be tested in an ISDN telephone and automatically performing a plurality of call tests and displaying the results.

It is also an object of the present invention to provide a call test method that automatically displays the cause of the failure by automatically performing a call test in the ISDN telephone.

According to the present invention for achieving the above object, in the call test method of a general information communication network telephone, a test key is input after registering a phone number and a call progress number to be tested, and registering the phone number and a call progress number to be tested. If so, the process of transmitting a setup message corresponding to the registered phone number, and the process of transmitting the setup message, receiving a call progress success status message and transmitting to an external terminal.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The block diagram of the ISDN telephone apparatus according to the present invention is the same as that of FIG. 1, and the same reference numerals are used.

3 is a flow chart of a call test control according to the present invention. Keypad investigation, phone number input and storage, call number input and storage, switching to a stored phone number, receiving an outgoing call and related call processing signals, and determining OK / NOK BYSY, etc. To display.

A preferred embodiment of the present invention will be described with reference to FIGS. 1 and 3 described above.

The phone number entered by the operator is stored in the test phone number. When the input of N phone numbers to be tested is completed, the test button is pressed and the number of repetitions is designated. The call starts. The result of each call is connected to the outside through the display unit 22 and the data port connection unit 14. ) Is displayed.

Referring to the operation of displaying the result of the call test with reference to the flowchart of FIG. 3, first, in step 301, the MPU 10 checks whether a key signal is input from the keypad unit 20, and if the key signal is input, step 302 is performed. Proceed. In step 302, the MPU 10 checks whether a setup key is input and proceeds to step 303 when the setup key is input.

In step 303, the MPU 10 inputs a telephone number to be tested from the keypad 20, stores it in the memory 18, and proceeds to step 304. In step 304, the MPU 10 inputs the number of call progresses to be tested from the keypad unit 20, stores the result in the memory 18, and returns to step 301. However, if the setup key is not input in step 302, the process proceeds to step 305 and checks whether the test key signal is input from the keypad 20. If no test key is input, the process returns to step 301. Proceed. In step 306, the MPU 10 determines whether a test end key signal is input from the keypad 20, and if the test end key is not input, the MPU 10 proceeds to step 307. In step 307, the setup message corresponding to the telephone number stored in the memory 18 is transmitted, and the flow proceeds to step 308. In step 308, the MPU 10 checks whether there is a message reception response from the counterpart. If there is a message reception response, the MPU 10 proceeds to step 309. In step 309, the MPU 10 checks whether the other party is empty. If the other party is not empty, the MPU 10 proceeds to step 311 to send a busy tone or NO OK message and proceeds to step 312.

If the opponent call is empty in step 309, the process proceeds to step 310, and the MPU 10 sends an OK message and proceeds to step 312. In step 312, the MPU 10 controls the line connection unit 16 to turn off the telephone line and proceeds to step 313. In step 313, the MPU 10 transmits the telephone number and the call progress result message to which the setup message is transmitted through the data port connection unit 14, and displays the information on the display unit 22 until the call progress test is completed. Repeat this.

As described above, the present invention stores the phone number to be tested in the ISDN telephone and the number of call progresses to be tested in the memory, and then enters a test key, and sends a setup message corresponding to the telephone number to be tested. Since the result of the voice call progress is displayed correctly, the accurate cause of failure can be detected.
