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

4 is a view showing the main functional block of the electronic switchboard having a caller information display service function according to a preferred embodiment of the present invention, reference numerals for performing the same functions as in FIG. Omit.

Reference numeral 40 shown in Figure 4 is stored in the subscriber number and the subscriber information corresponding to each subscriber number corresponding to the subscriber number transmitted from the destination exchange (B) when a particular subscriber information call from the destination exchange (B) A name DB system for providing subscriber name information, wherein the destination exchange B and the name DB system 40 communicate using the NO.7 signaling method and the INAP protocol.

On the other hand, the LSI-N (2 ') block performing the function of transmitting and detecting various tones for call connection in the ASS-S (10) to assume the present invention performs a function for providing caller information to the called party The CSI-N (Caller Identity Delivery Service Interface-New) function is implemented. In order to realize the function, the LSI-N is placed on the second shelf S1 of the subscriber control rack ASICR-N as shown in FIG. 5. A FSKA-N (Frequency Shift Keying generation board assembly-New) board having both a function and a CSI-N function and performing the LSI-N function and the CSI-N function properly under the control of the TLSP-N (7 ') is provided. Two sheets (FSKA-N0,1) are mounted.

Meanwhile, the backboard USBB-N corresponding to the second shelf S1 has two FSKA-N (0,1) boards and a USTA-N board for performing LSI-N functions as shown in FIG. 6. 2 pieces are mounted.

The FSKA-N board performs a function of generating frequency shifted modulation data, that is, frequency shift keying (FSK) data, and implements 16 channel capacity per board.

In addition, the FSKA-N board generates an FSK signal for a caller's telephone number or caller's name corresponding to caller information under the control of the TLSP-N (7 '), and sends the FSK signal to the TSL-N (3) in the form of a PCM signal. And a maintenance test function for the FSK generation function.

Referring to Figure 4 will be described in detail the operation of the electronic switchboard having a caller information display service function according to an embodiment of the present invention configured as described above.

Information on the calling subscriber using the R2 signaling method or the NO.7 signaling method in a state in which a call path between the caller accommodated in the originating exchange A and the called party accommodated in the called exchange B is formed. For example, if the calling party / calling party has transmitted whether or not the calling party information protection function is activated, the calling party information is transferred to the ASP-N through ASS-T (30) → INS (20) → TSL-N (3). (8 ').

Accordingly, the ASP-N 8 'determines whether the called party is a subscriber registered in the caller information display service function, and if the called party is determined to be a subscriber registered in the caller information display service function, information required by the called subscriber. For example, an originating number or a reason why the originating number cannot be transmitted is properly encoded and transmitted to the TLSP-N 7 '.

In this state, the TLSP-N 7 'transmits the data to the FSKA-N board mounted on the back board of the CSI-N block, and the FSKA-N generates the FSK signal corresponding to the data to generate the PCM. After conversion into a signal, the signal is transmitted to the ASI-N 1 through the channel of the TSL-N 3 occupied by the TLSP-N 7 '.

Here, the FSK signal converted into the PCM form is transmitted to the terminal display apparatus on the called party side via the TSL-N 3 and the ASI-N 1, and the terminal display apparatus processes the corresponding FSK signal. After detecting the calling party number included in the FSK signal, the calling party information, for example, the calling party number is displayed on the display means of the terminal display apparatus.

On the other hand, if the called party is registered up to the caller name display service of the caller information display service, the ASP-N (8 ') of the destination exchange A is TSL-N using the NO.7 signaling method and INAP protocol (3) Send the calling party number to the name DB system 40 via INS 20 → ASS-T 30 and call the calling party name information corresponding to that calling party number.

Thus, the name DB system 40 sends the caller name information corresponding to the calling party number to the ASP-N 8 'via ASS-T 30 → INS 20 → TSL-N 3. send.

The ASP-N (8 ') receiving the caller name information transmits the caller name information to the FSKA-N board of the CSI-N (2') block, and the FSKA-N board is connected to the caller name information. Generates a corresponding FSK signal, converts it to a PCM signal, and transmits it to the ASI-N (1) through the TSL-N (3), and corresponds to the caller name information restored to the FSK signal by the ASI-N (1). The FSK signal is reproduced through a terminal installed on the called party's side and output through the display means of the terminal as a character corresponding to the caller's name.

Through the above process, the called party registered in the calling party information display service can conveniently check the calling party number as well as the calling party's telephone number.

According to the present invention as described above, not only can the caller information display function be provided while minimizing the design change of the existing electronic switchboard, but also means for performing the caller information display function on the USTA-N board. There is also an advantage in maintenance by implementing and integrating the electronic exchanger.

On the other hand, the present invention is not limited to the above-described embodiment, but can be modified and modified within the scope not departing from the gist of the present invention, such modifications and changes should be regarded as belonging to the following claims. will be.
