Description

How to check the phone that performed the final MC in the key phone system

The present invention relates to a key phone system, and more particularly, to a method for identifying a key phone telephone that has performed a final MMC (MMC).

In general, the key phone system is a private exchange system consisting of the components as shown in Figure 1 performing a variety of functions required for the exchange. The function of each component will be described with reference to FIG. 1, and the controller 111 controls the call switching and controls the overall operation to provide various services to the user. The ROM 112 stores basic calls and programs and initial service data of the control unit 111 for performing various functions. The RAM 113 temporarily stores data generated during program execution under the control of the controller 111.

The switching circuit 114 switches various tones and voice data under the control of the controller 111. The subscriber circuit 115 supplies a call current to an extension subscriber (not shown) under the control of the control unit 111 and interfaces a signal between the extension subscriber and the switching circuit 114. Here, the extension refers to a line connecting the switching system and the subscriber telephone. The ring generator 116 generates a ring signal and supplies it to the subscriber line. The trunk line circuit 117 forms a trunk line call loop under the control of the control unit 111 to form a trunk line call loop, and interfaces a signal between the trunk line and the switching circuit 114. Here, the trunk line refers to a line that connects the trunk line circuit 117 and the national exchange.

The tone generator 118 generates various tone signals under the control of the controller 111 and outputs them to the switching circuit 114. The DTMF receiver 119 analyzes the DTMF signal input from the switching circuit 114, converts the DTMF signal into digital data, and outputs the digital data to the controller 111. The DTMF signal input to the DTMF receiver 119 through the switching circuit 114 may be a telephone number generated by the trunk line subscriber or a telephone number generated by an extension subscriber. The DTMF transmitter 120 converts the digital data output from the control unit 111 into a DTMF signal and outputs the DTMF signal to the switching circuit 114. Here, the DTMF signal output from the DTMF transmitter 120 becomes the telephone number of the trunk line subscriber generated when the station side calls the trunk line side.

The key phone system having such a configuration uses the MMC as a means of controlling the system. In general, the key phone system allows the MMC to be used by any key phone telephone, and is managed by a password to restrict access to the system.

However, when the password is known and someone controls the system with the MMC as needed, the conventional key phone system was unable to track the use where the MMC was performed. If someone accesses the system and changes the system configuration arbitrarily or performs the wrong MMC, if the problem occurs because the user did not know the user who performed the MMC, he or she must find and confirm the user who finally performed the MMC to recover the system. As a result, it took a long time to recover the system or even failed to recover the system.

Accordingly, an object of the present invention is to provide a method for easily identifying a place where MMC is performed in a key phone system.

In order to achieve the above object, the present invention provides a method for verifying a telephone that performs a final MMC in a keyphone system capable of MMC, and stores a keyphone telephone number for performing the MMC every time the MMC is performed, and if necessary, the final MMC. When the confirmation code is entered, the final MMC key phone telephone number is displayed, and the user is notified of the user who performed the final MMC.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention, such as specific processing flows. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. Detailed descriptions of well-known functions and configurations that are determined to unnecessarily obscure the subject matter of the present invention will be omitted. The configuration of the key phone system according to the present invention is the same as that of FIG. 1, and it should be noted that the same reference numerals as the components of FIG. 1 are used when describing the present invention.

In order to install and use the key phone system according to the usage environment, the key phone system is controlled through the MMC. The memory according to the present invention includes the ROM 112 and the RAM 113, which are backed up to protect the contents of the MMC even when the power is turned off. UP) consists of a key-phone system that backs up the RAM 113 with a battery. Hereinafter, a preferred embodiment of the present invention will be described in detail. First, an operation of storing a key phone telephone number for performing MC according to the present invention will be described with reference to the flowchart of FIG. 2.

In step 201, the control unit 111 receives an MMC start key through a keypad of a key phone (not shown) capable of performing an MMC connected to the subscriber circuit 115. Then, in step 202, the control unit 111 receives the MMC password for performing the MMC through the keypad of the key phone. Then, in step 203, the control unit 111 determines whether the MMC password inputted from the key-phone telephone through the subscriber circuit 115 is compared with the previously registered MMC password. If the MMC password is incorrect, the control unit 111 proceeds to step 204 and outputs an error for notifying an error to the key phone user currently performing the MMC. In this case, the password input process may be repeated several times in the case of the password mismatch according to the user setting. If the MMC password input by the key-phone telephone user and the registered MMC password match, the control unit 111 operates the MMC control mode in step 205 to control the MMC execution mode according to the request of the key-phone telephone user. Thereafter, in step 206, the control unit 111 checks whether the MMC end key is input from the key phone user. If the MMC end key is input, the process proceeds to step 208. If the MMC end key is not input, the process proceeds to step 207 to determine whether the set time has elapsed. The set time elapsed inspection is mostly programmed to force MMC mode to be forcibly terminated by the keypad system when a certain time elapses without any key input from the user in MMC. Refers to the action to check. If the set time has elapsed and the set time has elapsed, the process proceeds to step 208. If the set time has not elapsed, the process returns to step 206 and waits for input of an end key. In step 208, the control unit 111 stores the key phone number (ID) on which the MMC is performed in the designated backup memory (RAM) 113, and then terminates the MMC. Whether the MMC is performed in the key phone telephone connected to the key phone system, the control unit 111 stores the key phone telephone number performing the MMC. When storing the key phone telephone number, all the key phone telephone numbers performing the MMC may be stored by date and time, or only the key phone telephone numbers performing the final MMC may be stored.

In this way, the phone phone number that used to perform the MMC is stored in the backup memory (RAM) 113 of the key phone system, and the system administrator or another user of the key phone system changes the system configuration, discovers the wrong MMC, or finally performs the MMC when necessary. Referring to FIG. 3, a system manager or another user of a key phone system inputs an MMC start key through a key phone phone capable of performing MMC in step 301, and the control unit 111 receives the input through the subscriber circuit 115. . After that, the control unit 111 receives the MMC password in step 302, and in step 303, determines whether it matches the pre-registered MMC password, and if it matches, proceeds to step 305, and if it does not match, proceeds to step 304 to output an error to the MMC. Inform the user about the password mismatch error. Only when the passwords match, the control unit 111 proceeds to step 305 and stores the key phone phone number currently performing MMC in the designated backup memory (RAM) 113 and proceeds to step 306. In step 306, the control unit 111 displays that the MMC control mode is being performed on the display unit (not shown, for example, LCD) of the user's key phone. Then, in step 307, the control unit 111 detects this when the user inputs the final MMC key phone confirmation code in order to confirm the key phone phone that performed the final MMC and proceeds to step 308. In step 308, the control unit 111 reads out the final MMC performing key phone telephone number from the designated storage area of the backup memory (RAM) 113 storing the key phone telephone number on which the MMC is performed, displays it on the user's key phone telephone display, and then ends. By performing the above operation, the system administrator or another user who wants to know the user who performed the final MMC may know the user where the final MMC is used.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention enables the administrator of the key phone system to quickly identify which phone performs the MMC control of the system in order to efficiently recover the system, thereby enabling more efficient system recovery and management. .
