The present invention relates to a method for registering an extension subscriber number used in an automatic attendant of a private exchange, and more particularly, to a method of registering a large number of subscribers with a minimum of memory.

In general, an auto attendant is an additional terminal device that automatically responds to an incoming call from an outside and transfers the incoming call to an extension subscriber who wants to make a call. It is also used in connection with a simple branch exchange (also known as a kitellipon system).

1 shows a connection configuration diagram of a private switching system to which an automatic repeater is connected. Here, reference numeral 12 denotes a subscriber circuit having a matching function with a trunk card performing a matching function with a central office line 14 and an extension 16 or another extension 18. It refers to a general private exchange (PABX) capable of performing a call service (or vice versa) by connecting a call of the trunk line 14 to an internal station 16 or 18 including a line circuit. 20 is an automatic repeater which is an additional terminal device of an exchange, and 22 is a normal telephone.

In FIG. 1, each of the extensions 16 and 18 is assigned a unique extension number (premises subscriber number) from the private exchange (actually, hardware connected to the subscriber port corresponding to the extension number). The automatic repeater 20 includes a central processing unit for processing various signals and a memory for storing and outputting various data. In the telephone exchange system connected as shown in FIG. 1, the call is programmed to be automatically connected to the extension 18 to which the auto attendant 20 is automatically connected when the telephone line is received.

The feature of this additional terminal device is that the telephone automatically answers the incoming call and transmits a preset auto answer message to the trunk line 14. That is, when a call is received from the CO line 14, the incoming call is automatically connected to the extension 18 by the program of the private exchange 14. At this time, the automatic repeater 20, which is the additional terminal device, automatically responds to the incoming call, transmits a preset automatic response message, is inputted to the trunk line 14, and is received through a call path in the private exchange 12 ( DTMF: Dual tone multi-freqency. At this time, the auto-answer message is a response message containing the information to press the extension number (also called subscriber number or premises phone number) that you want to call.

When the other party who listens to the auto-answer message enters the extension number as DTMF, it is input to the auto attendant 20. The auto attendant 20 outputs a call transfer signal to a private automatic branch exchange or a simple exchange so that the incoming call can be transferred in the same manner as the existing operator switches the phone to the corresponding station.

Therefore, the automatic repeater 20 as described above should accurately recognize whether the extension number transmitted from the outside is an extension number not used or an extension number used. That is, if the call transfer signal (extension number selected by the other party's telephone subscriber as DTMF) of an incoming call is an unused extension number, a message of an extension number not used immediately should be transmitted to the outside. For this operation, it is necessary to accurately register all the telephone numbers of the respective stations which are connected to the private switchboard 12 and receive the service service in the automatic repeater 20.

2 is a control flowchart of a subscriber number registration method of a conventional automatic repeater.

3 is a memory map table registered by the conventional registration method, which is a memory located in the automatic relay station 20. As shown in FIG.

Hereinafter, a method for registering an extension number in the conventional automatic repeater 20 will be described with reference to FIGS. 2 and 3.

Now, the extension number registration method of the automatic repeater 20 shown in FIG. 1 uses the subscriber number of the extension 18 to which the automatic repeater 18 is connected to the ordinary telephone 22 connected to the extension 16. FIG. Begin by dialing. When the auto attendant 20 is called by the telephone 22 of the extension 16 shown in FIG. 1, the auto attendant 20 automatically transmits a voice message indicating that a connection is made in response to an incoming call of the extension. It sends out to the telephone 22 of 16).

If the automatic repeater 20 does not have a function to send an auto-response message, it transmits a connection tone indicating that a connection is established. When the user who listens to the connection message or the beeping signal as described above inputs a password and a registration code using the keypads of the telephone 22, the automatic repeater 20 performs the routine of the registration mode as shown in FIG.

The automatic repeater 20 transitioning to the registration mode as shown in FIG. 2 initializes the registration address of the memory for registering the extension number, and searches whether the extension number is received from the telephone 22 in which the call path is formed. Here, initializing the registration address means selecting the initial address of the registration memory configured as shown in FIG. 3 as a place to first write.

When the user (or operator) inputs the extension number using the keypad of the telephone 22 in which the call path is formed in the state of performing the above initialization, the automatic repeater 20 inputs the registration number to the registered address of the corresponding memory. The extension number to be registered is recorded (recorded), and the registration completion code is searched for. Here, the registration completion code is a code for stopping the registration operation of the automatic repeater 20, for example, a code of the form # 68.

If it is not a registration code in the search process, the automatic repeater 20 increases the registration address of the registration memory configured as shown in FIG. 3 to set the next registration address. However, if the registration completion code is entered in the search process, the automatic relay pod 20 releases the registration mode and ends the registration mode. Therefore, when the extension number stored in the private switch 12 is registered in the automatic repeater 20 by the control procedure as shown in FIG. 2, one extension number is registered in one address area in the extension number registration memory. It can be seen that together.

However, in the conventional automatic repeater extension number registration method, there is a problem that a large amount of memory must be secured in order to register the extension number. The reason for this has been to increase the price by registering all the extension numbers accommodated in the private exchange 12 one by one and having a huge size registration memory in the case of a large number of used players. For example, if the extension subscriber accommodated in the private exchange 12 is 200 subscribers and the extension number is 200 to 399, the memory for registering 200 extension numbers requires 200 × 3 digits. Able to know. In this case, if the data bit representing one digit is 4 bits, a total of 300 bytes of storage capacity is required to register a total of 600 digits of the extension number, and it takes a long time to search for the registered extension number. There was also this very much trouble. In addition, the registration method is also very inconvenient to register the extension number in the automatic repeater 20 by manually inputting the extension number 200 to 399.

Accordingly, it is an object of the present invention to provide a method for registering an extension number stored in a private exchange as a minimum size memory in an automatic relay station.

Another object of the present invention is to provide a registration method that can be quickly registered by designating the extension numbers accommodated in the private exchange as a group.

The present invention for achieving the above object is connected to an incoming call from a trunk line to a preset incoming station, the switching unit for switching the incoming call in response to a call transfer signal from the incoming station, and connected to the incoming station A method for registering an extension number of an auto attendant with an auto attendant for transmitting a preset message in response to an incoming call, searching for an extension number input from an extension number registration memory, and transmitting a call transfer signal to the exchange. Initializing the address and displaying the code signal input from the outside, and storing the input extension number and the attribute code in the temporary buffer in response to the case where the input code is the extension number and the attribute code. A temporary storage process of data, and a response if the input code is an address change code An address change process of changing the address into an address area of a destination; and in response to the input code being a registration completion code, the temporarily stored extension number and attribute code are stored in a storage location and an attribute code storage location in an actual extension number table. It is characterized by consisting of a registration process of registration.

Hereinafter, with reference to the accompanying drawings, the operation of a preferred embodiment of the present invention will be described in detail.

4 is a control flowchart of a method for registering a subscriber number of an automatic relay station according to the present invention, which shows an operation control procedure of the automatic relay station 20 shown in FIG.

5A and 5B are memory map tables according to the present invention, which are maps of the extension number registration memory of the automatic repeater 20 shown in FIG. The structure of this memory map includes an extension number storage area (12-bit area) DTN in which data corresponding to three digits (three numbers) is stored for every address ADD, and an attribute code area (in which an attribute code is stored) SUR). In this case, the extension number is an example of three numbers, and the attribute code has a length of 4 bits as data of one number or character (symbol).

The attribute codes of the attribute code area SUR in FIGS. 5A and 5B are distinguished by numerals and character symbols. Here, the number is a code for determining how many extension numbers are automatically registered in succession from the extension number storage area DTN of the current address ADD. For example, if 400 is stored in the extension number area DTN of the current address ADD and the number 7 is stored in the attribute code area SUR, the extension number 400 stored in the extension number area DTN is stored. It means that the extension number continues from the number 407 to the number 407. In other words, it actually registers four digits and automatically registers eight extension subscriber numbers. If the code stored in the attribute code area SUR is registered with the symbol *, the extension number is stored from the extension number storage area DTN of the current address to the extension number stored in the extension number storage area DTN of the next address. It means that it is continuous. For example, 200 extension numbers are stored in the extension number area DTN of address 00H in FIG. 5A, and an extension code area of the next address 01H is stored in the attribute code area SUR. If the extension number 399 is stored in the file name), it means that the extension number 200 to 399 is continuously registered.

6 shows an example of the display in the registration mode according to the present invention, which is an example displayed on the automatic repeater 20 in the registration mode. In Fig. 6, the preceding two display states are for displaying addresses, the four display states at the next position are for extension numbers, and the last display state is for displaying attribute codes.

Hereinafter, a method of automatically registering an extension number of the automatic repeater 20 according to the present invention, and a relationship of searching for an extension number registered by such a method and transmitting a call transfer signal to the private switch 12 will be described.

Now, if an operator registers an extension number by the method according to the present invention in the extension number registration memory located inside the automatic repeater 20 shown in Fig. 1, the operator is connected to the extension 16 as described above. After calling the automatic repeater 20 using a general telephone (22) to connect the call path must enter a password and registration code. When the operation is executed as described above, the automatic repeater 20 performs the routine of the registration mode as shown in FIG.

The automatic repeater 20 which performs the routine of the registration mode as shown in FIG. 4 initializes the registration address of the extension number registration memory configured as shown in FIG. 5A in step 42 of FIG. 4 and displays the display format as shown in FIG. . Initialized registration addresses are displayed in the first position of the display format as shown in FIG. Initializing the registration address here designates an initial address of the extension number registration memory having the memory map as shown in FIG. 5A.

In step 42 of FIG. 4, the automatic repeater 20 which initializes the registration address and displays the display format as shown in FIG. 6 in order to input data, in FIG. 44 and 46, ext. Search for change code input. If it is determined that the corresponding code is not input in steps 44 and 46, the automatic repeater 20 detects the input state of the registration completion code in step 60, and determines that the registration completion code is not entered. In step 62, it is determined whether a predetermined time has elapsed. When no code is input such that a predetermined time elapses in the searching process, the automatic repeater 20 cancels the registration mode.

If the operator who sees the message as shown in FIG. 6 in the code input search process as described above inputs the extension number and the attribute code to DTMF using the telephone 22, the call path of the private exchange 12 is entered. The automatic repeater 20 is input to the automatic repeater 20, and the automatic repeater 20 determines that the extension number and the attribute code are input in the process of FIG. The automatic repeater 20 determines that the extension number and the attribute code are input, and stores the input extension number and the attribute code temporarily set in the RAM area therein. Then, the input state of the continuously input code is searched through the search of steps 44, 46, 60, 62 and the like. Here, the attribute code means a code that is continuously received after receiving the extension number, and is also received as a DTMF signal. For example, if the number of digits (digit number) is 3 digits, the number or letter symbol (*, for example) received after the 3 digits is recognized as an attribute code.

In the present invention, the attribute code is set as a number or a letter symbol, and the attribute code of the number is automatically registered up to the extension number added by the number of the attribute code to the value of the extension number stored in the extension number storage area DTN of the current address. The attribute code of the character code is registered continuously from the value of the extension number stored in the extension number storage area DTN of the current address to the value of the extension number stored in the extension number storage area DTN of the next address. Information to indicate.

If it is determined by the above-mentioned step 60 that the registration code (for example # 70) is input by the above search, the automatic repeater 20 determines whether the input of the extension number and the attribute code has been completed in step 56 of FIG. Search. That is, it is searched whether 3 digit extension number and 1 digit attribute code have been input. The automatic repeater 20 that has completed the input of the extension number and the attribute code by the searching process as described above registers the registered address initialized to the extension number and the attribute code stored in the temporary buffer by the steps 44 and 50 mentioned in step 58. Stores in the extension number area DTN and the attribute code area SUR indicated by and cancels the registration mode. However, when the input of the extension number and the attribute code is not completed while the registration completion code is input, the automatic repeater 20 cancels the registration mode.

When the registration completion code is input while the three-digit extension number and the one-digit attribute code are continuously input by the above operation, the automatic repeater 20 displays the extension number area DTN indicated by the initialized registration address. At the same time, the three-digit extension number is stored and the one-digit attribute code is automatically stored in the attribute code area SUR of the current address. For example, when the user enters 200 extension numbers in the extension number area DTN of the registered address 00H and inputs an attribute code of *, the auto attendant 20 automatically registers the registered address 00H. A 200 is recorded in the extension number area DTN at the same time, and an attribute code of * is recorded in the property code area SUR, and the extension number is continued up to the extension number 399 stored in the extension number area DTN of the current address (00H). It will be recognized. However, if the registration completion code is entered in the state in which the extension number 400 stored in the temporary buffer is 400 and the attribute code is 5 by the above-described steps 44 and 50 in the state where the registration address is 02H, the automatic repeater 20 In step 58, automatically records 400 in the extension area DIN of the current address (02H) and automatically stores 5 in the property code area (SUR), thereby recognizing that the extension number 400 has been registered up to extension 405. .

If the extension number and the attribute code are not input in step 44 of FIG. 4 and the address change code is input in step 46, the automatic repeater 20 is displayed as shown in FIG. 6 in step 48 of FIG. Change the extension number to the currently entered extension number. For example, if the address changed by the address change code is 03H while the current address is 01H, the registration position is changed to the address of 03H.

By the above operation, the state registered in the extension number registration memory is as shown in Fig. 5A. 5A is an example of registering a total of 219 extension numbers. That is, 200 extension subscribers of extension numbers 200 to 399, 6 extension subscribers of extension numbers 400 to 405, 8 extension subscribers of extension numbers 410 to 407, and extension number 420 A memory map showing an example of registering a single extension subscriber and four extension subscribers of extension numbers 430 to 433.

Referring to FIG. 5A, an example of registering 200 extension subscribers from the extension numbers 200 to 399 with the size of 4 bytes in the two buffer areas of the address 00H and the address 01H. The attribute code * stored in the attribute code area SUR of the address 001H is the extension number area of the next address 01H from the extension number 200 stored in the extension number area DTN of the address 00H as described above. It means that the serial number up to extension 399 stored in the DTN) is continuously registered.

As described above, the present invention can register the extension number accommodated in the private branch exchange 12 as the minimum size when registering the automatic repeater 20.

In the following process, the automatic repeater 20 having registered the extension number searches for the extension number in response to an incoming call and transmits a call transfer signal to the private switch 12 to convert an external call to an extension subscriber. Explain.

Now, when an incoming call is input from the trunk line 14, the private exchange 12 sends the incoming call to the trunk line 14 to the extension 18 to which the automatic repeater 20 is connected. At this time, the auto attendant 20 automatically responds to an incoming call and transmits a preset auto-response message through the private exchange 12 to analyze the input signal DTMF. Here, thank you as an example of an answering machine. This is 000 Corporation. Please enter the extension number you want to call and you will be connected immediately.

When an external caller who listens to the auto-answer message inputs an extension number desired for a call as a DTMF signal using the keypad of the MFC telephone, it is immediately transmitted to the auto attendant 20. At this time, the automatic repeater 20 analyzes the received DTMF signal (converts it into digital data using a DTMF receiver and recognizes it as a call extension number), and searches whether the received extension number is registered in the extension number registration memory. do.

At this time, a process of searching whether the received extension number is registered in the extension number registration memory is as follows. When the extension number transmitted and received from the other party is 404, the auto attendant 20 searches for the contents of the extension number stored in all addresses of the internal extension number registration memory, and the highest digit, that is, the hundreds digit, is registered as 4XX. Find out if there is anything. If there is an extension number registered with four hundred digits, search the property code by reading the property code of the corresponding address. If the attribute code is *, the value of the extension number registered in the next address is read to see if it is equal to or greater than the value of 404. If it is determined that the value of the extension number registered in the next address is greater than or equal to the received extension number 404, the auto attendant 20 recognizes that the extension number is registered in the private exchange 12 and the call transfer code is private. Transfer to the exchange 12.

If the search result of the attribute code as described above is not the code, the automatic repeater 20 is connected to the attribute code stored in the attribute code area SUR at the number 400 stored in the extension number storage area DTN of the address 02H. A value is added and it is searched whether the received extension number 404 exists between the added value 405 and the registration number 400. As a result of such a search, if it is determined that the received extension number exists in the extension number stored in the extension number area of the corresponding address and the attribute code added to the extension number, the auto attendant 20 transmits to the private switch 12. It recognizes the registered extension number and transmits the transfer code to the private exchange 12. Here, the call transfer code means a hook flash signal and an extension number or a digit and extension number for call transfer.

The private exchange 12 which inputs the transfer code from the auto attendant 20 transmits the call path of the trunk line 14 to the transfer code in response to the transfer code transmitted from the auto attendant 20. The call forwards to the included extension. Therefore, it can be seen that the incoming call from the CO line 14 is automatically relayed.

As described above, the present invention efficiently stores the memory by inputting the registration of the extension number used in the private exchange in the minimum information unit into the auto attendant connected to the extension of the private exchange and automatically relaying an external incoming call. It can be used, it is also possible to quickly search for the extension number when the incoming call is input, there is an advantage that can be quickly connected to the call.
