And a third step of searching whether the personal call number is found in the personal call number table, and when the personal call number is not found in the search of the third step, giving a ring tone and finding the port stored in the personal call number area. The fourth step is to delete the number to save null data and give a deletion confirmation tone.

An operation example of the present invention will be described in detail with reference to the block diagram of FIG. 1 and the second, third, fourth, and fifth embodiments. First, the process of registering an individual number by a certain person of certain premises with irregularities will be described. When a specific person in the premises hooks a port number of 33 and the subscriber's telephone number of the extension telephone number 201 (hereinafter referred to as an extension) (STN.A) to register a personal call number, The hook-off state of the subscriber station STN.A is sensed by the MPU 10 which scans the subscriber circuit 40 at regular intervals. At this time, the MPU 10 transmits a switching control signal and a dial tone control signal to the digital switching circuit 50 and the digital tone supply circuit 60 by the operation system (OS) program data read from the memory unit 20. Respectively outputs the channel of the subscriber subscriber station STN A of the subscriber circuit, and supplies a tone to the receiving channel of the subscriber subscriber station STN A.

When a specific person of the subscriber (STN A) who listens to the dial tone by the above operation dials the registration code "*" for registration of the personal call number, the dialing digit generated by the subscriber (STN A) is a tone receiver ( DTMF Receiver (70), whereby the dialing digit of the subscriber (STN A) is converted into digital data by the operation of the receiver 70 is input to the MPU (10) through the interface.

The MPU 10 which inputs the dialing digit digital data of the subscriber subscriber STN A analyzed by the tone receiver 70 analyzes it and checks whether it is a general function code in step 3a. If not, check if the registration code is correct in 3b.

If it is not a registration code in the search process of 3b, the MPU 10 outputs the tone sound control signal to the tone supply circuit 60 in order to hear a Not Use Tone, and if the registration code is correct, 3c. In the process, a transfer tone control signal is output to the tone supply circuit 60.

Therefore, the specific person who hooks up the subscriber station STN A and dials the registration code "*", receives the switching channel and the subscriber of the time switch 50 from the supply circuit 60 under the control of the MPU 10. The circuit 40 listens to the handset.

When a specific person of the subscriber (STN A) who has received the switching sound as described above dials his personal call number, for example, "123", it is converted into digital data by the tone receiver 70 as described above and is interfaced. Input to the MPU 10 via the (30).

At this time, the (10) detects whether the personal call number dialing is completed, and cuts the switching sound by controlling the tone supply circuit 60 in step 3e when the personal call number is input.

In step 3e, the MPU 10, which cuts off the switching sound, accesses the personal call number table of FIG. 2 located in the memory 20, searches the address area of the dialed personal call number, and searches whether the number exists in the number table. Search in the process. If the private call number " 123 " is not in the address area in the 3f retrieval process, the digital tone supply circuit 60 is controlled to supply a Not Use Tone to the reception channel. If the personal call number (PCN1) is "123" in the table of FIG. 2, the MPU 10 saves the port number "33" of the current subscriber (STN A) in the PCN1 area to the PCN1 area in step 3g. In step 3h, the digital tone supply circuit 60 controls the digital tone supply circuit 60 to supply the receiver of the specific person of the confirmation tone subscriber (STN A) and terminates the registration of the personal call number.

As described above, when the subscriber STN B hooks off to find a specific person who has a personal call number of "123" while the personal call number of the specific person whose residence is not fixed is registered, the dial tone is dialed as described above. Will receive. When the subscriber (STN B) dials the call code # in the state of receiving the dial tone as described above, it is converted into digital data by the above-described path and input to the MPU 10.

The MPU 10 that inputs the dialing data searches for whether the dialed digit is the data of the general code in step 4A, and if it is determined that the code is a general code, performs the general call processing. Search for. Step 4b is a process of searching as an option. If the call is granted in step 4b, the input dialing digit searches for call code authorization in step 4c, and if the search result is not a call code, the tone supply circuit 60 is controlled to transmit a Not Use Tone to the subscriber. Supply to the receiving channel of B).

If the input dial digit is a call code in step 4c, the digital tone supply circuit 60 is controlled in step 4d to supply a switching sound to the receiving channel of the subscriber station STN B, and the call number of " 123 " If the call number of the specific person having a multi-input MPU 10 controls the tone supply circuit 60 in 4f to cut the transmission of the switching sound.

In step 4f, the MPU 10, which cuts off the switching sound, searches whether the address of the personal call number " 123 " entered in the personal call number table in the memory unit 20 is found in step 4i. If the address is out of range, the tone is sent.

When the private call number field is found in step 4i, the port number "33" stored in the corresponding private call area PCN1 ("123") is accessed in step 4i.

In step 4j, the MPU 10 accessing the port number “33” in which the specific person having the private call number “123” is located, performs a 4k process of the subscriber (STN A) having the extension number “201” corresponding to the port number. After finding in, the extension ring (Ring) is sent to the extension subscriber (STN A) to form a currency path. If it is determined in step 4b that the current system state is not a call code assignment state, the MPU 10 determines whether the first digit of the input dial digit is the first digit "1" (1st Number) of the personal call number. Analyze at

If the analysis result of the 4g process is the first digit of the input dialing digit is the same as the first digit of the personal call number, it is determined that the call code and wait until the personal call number dialing is completed to perform the above-described process 4i at completion, the personal call number A currency path is formed with the registration specific person of "123".

On the other hand, a specific person who has registered the private call number "123" in the port of the subscriber (STN A) cancels the call and deletes the call from any subscriber port while listening to a dialing tone. Dialing, this also causes the MPU 10 to analyze the input of the dialing digit as described above.

At this time, the MPU 10 performs a general call processing even when the input digit is a deletion code in step 5A of FIG. 5A, and outputs a switching sound control signal to the digital tone supply circuit 60 when the deletion digit is detected. Is given to the subscriber who is currently dialed in step 5b.

When a particular person holding an arbitrary extension telephone receiving a switching tone dials the personal call number registration code " * " and the personal call number " 123 " consecutively, the MPU 10 enters the dialing digit code in step 5c to enter 5d. In step 5e, it is determined that it is a registration code.

When the personal call number "123" is input in step 5e, the MPU 10 controls the digital tone supply circuit 60 in step 5f to cut the switching sound and input the personal call number "123" in step 5g. It is searched whether or not it exists in the address area of the private call number table located in this memory unit 20. FIG.

If the personal call number "123" currently input in step 5g exists in the table, FFH which is null data indicating that the port number "33" saved in the personal call number "123" area PCN1 is in an initial state. Change to and delete in 5h process.

The MPU 10 deleting the personal call number outputs a confirmation tone control signal to the tone supply circuit 60 to give a confirmation tone to a specific person in step 5f. Therefore, any station subscriber can easily call a specific person with a personal call number by using the station subscriber's telephone number to record the subscriber's port number in his / her personal call number area. Find and talk.

As described above, the present invention can perform a function of registering, calling, and deleting a personal call at an arbitrary subscriber location, and can make a call with a desired person immediately when necessary through such a personal number registration and calling function. In addition, it is possible to immediately connect calls from external subscribers to anyone at any place in the premises, providing a further enhanced service that combines convenience and speed with the convenience of using a private automatic branch exchange. There is an advantage to ensure the reliability of the system.
