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 switch with a caller information display service function according to an embodiment of the present invention, the reference numeral for performing the same function as in FIG. Omit.

Reference numeral 40 shown in FIG. 4 denotes a subscriber name and subscriber information corresponding to the subscriber number transmitted from the destination exchange B when particular subscriber information is called from the destination exchange B by storing subscriber number and subscriber information corresponding to the subscriber number. As a name DB system for providing information, the destination exchange B and the name DB system 40 communicate using NO.7 signaling and INAP protocol.

Meanwhile, a Caller Identity Delivery Service Interface (CSI) block is additionally configured in the LSI 2 'that performs the function of transmitting and detecting various tones for call connection in the ASS-S 10. The CSI block is illustrated in FIG. As shown in FIG. 3, the third shelf S2 of the subscriber control rack ASICR is configured.

Here, the back board USBB corresponding to the third shelf S2 has two PBU boards, which are boards for supplying power as shown in FIG. 6, mounted on both sides, and a USTA board for performing the LSI function. 10 sheets of 5 sheets (USTA0-4) are mounted for redundancy, and 2 PPHA (PPHA0,1) boards for redundancy are mounted to perform the LSP function. Two FSKA (Frequency Shift Keying generation board assembly) boards are mounted (FSKA0,0).

The FSKA board performs a function of generating frequency shifted modulation data, that is, frequency shift keying (FSK) data, and is implemented with 16 channels per board.

The FSKA board converts an FSK signal into a PCM signal under the control of an LSP corresponding to the PPHA board, and sends it to the TSW 3 to implement 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 caller ID / caller sends a call, whether the caller ID protection is activated or not, the caller information is ASS-T (30) → INS (20) → LDL (4) → TSW (3) → TSP. It is passed to the ASP 8 through 7.

Accordingly, the ASP 8 'determines whether the called party is a subscriber registered in the caller information display service function, and if it is determined that the called party is a subscriber registered in the caller information display service function, information required by the called party, for example, Send the LSP (6 ') by encoding the calling number or the reason why the calling number cannot be sent.

In this state, the LSP 6 'transmits the data to the FSKA block corresponding to the CSI block. The FSKA generates an FSK signal corresponding to the data and converts it into a PCM signal. It occupies the channel of and is transmitted to the TSW 3.

The PCM signal corresponding to the FSK signal is restored to the analog signal corresponding to the FSK signal via the TSW 3 and the ASI 1 and then transmitted to the terminal display apparatus on the called party's side. Caller information indicated by the FSK signal, for example, caller ID is displayed.

On the other hand, if the called party is registered up to the caller name display service among the caller information display service, the ASP 8 'of the called exchange A uses TSW (3) → using the NO.7 signaling method and INAP protocol. The sender number is transmitted to the name DB system 40 via LDL (4) → INS (20) → ASS-T (30) and calls the caller name information corresponding to the caller number.

Thus, the name DB system 40 transmits the caller name information corresponding to the caller number to the ASP 8 'via ASS-T 30 → INS 20 → TSW 3.

The ASP (8 ') receiving the caller name information transmits the caller name information to the FSKA block of the LSI (2'), and the FSKA block generates an FSK signal corresponding to the caller name information to generate a PCM signal. Is converted to the ASI 1 through the TSW 3, and the FSK signal corresponding to the caller name information restored to the FSK signal by the ASI 1 is reproduced through the terminal installed on the called party's side. And output through the display means.

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 the means for performing the caller information display function can be implemented on the USTA board. There is an advantage in maintenance as well by integrating with the electric alternator.

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.
