One modem modem access board (230: TDLB) currently used has eight modem functions. One modem function consists of one modem and two flash ROMs to provide two-channel pulse code modulation (PCM) data. I'm going to handle Therefore, 16 flash ROMs are used for one subscriber modem access board 230 (TDLB), 8 subscriber modem access boards 230 (TDLB) are used for one telephone network matching device 10: TNAS, and one large capacity is used. Since 10 telephone network matching devices 10 (TNAS) are used in the communication processing system 100, a total of 1280 flash ROMs are used.

Therefore, when there is a need to replace the contents of the flash ROM of the subscriber modem access board 230 (TDLB), for each of the flash ROMs, the process of disconnecting from the socket and writing new software, and again Since it was necessary to repeat the process of inserting into the flash ROM socket, updating the contents of the flash ROM is time-consuming and cumbersome.

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

3 is a block diagram of a subscriber modem access board (TDLB), in which eight modem function units 310 are used for one subscriber modem access board 230 (TDLB), and one modem function unit 310 is one. The modem 413 and two flash ROMs 411 and 412 are configured to process two channels of pulse code modulation (PCM) data. Therefore, 16 flash ROMs are used in one subscriber modem access board 230 (TDLB).

In this case, the control logic unit 330 controls the modem function unit 310 to perform a function of converting serial data of two channels and pulse code modulation (PCM) data of two channels.

The microprocessor 320 is also connected to the processor matching board 220 (TPIB) and the signal processing board 250 (TSPB) via an interprocessor communication (IPC) link 103 and has its own address bus for all flash ROMs. And access via a data bus and access to the flash ROM via an address bus and a data bus.

4 is a flow chart according to the method of the present invention.

First, the operator inputs an access code of the mass communication processing system 100 using an arbitrary terminal 13 (PC) connected to the mass communication processing system 100 through the public telephone network 11 (S410). ).

At this time, the terminal 13 should be provided with a modem, and the operator connects with the mass communication processing system 100 by inputting a predetermined access code such as "1410" after starting a predetermined communication program.

When the access code input by the operator in step S410 is transmitted to the signal processing board 250 (TSPB) of the telephone network matching device 10 of the mass communication processing system 100, the signal processing board 250 (TSPB) is the terminal 13 It transmits a predetermined initial screen to the (S420).

That is, with the access code input in step S410, the operator's terminal 13 is connected to the corresponding mass communication processing system 100 through its own modem, the connection state of the signal processing board (10) of the telephone network matching device (10). 250: TSPB). Then, the signal processing board 250 (TSPB) transmits a predetermined communication initial screen to the terminal 13 of the operator. This is a process for confirming that the operator is connected with the mass communication processing system 100.

The operator who receives the initial screen from step S420 transmits an update command of the flash ROM using the terminal 13 (S430).

At this time, the flash ROM update command to use a special code, not the command codes generally used in PC communication, the flash ROM update command input by the operator through the modem of the terminal 13, the corresponding mass communication processing system 100 Is transmitted to the signal processing board 250 (TSPB).

Now, the signal processing board 250 (TSPB) receiving the update command of the flash ROM authenticates whether the operator is an allowed operator (S440).

That is, since the flash ROM update is to change the performance and structure of the mass communication processing system 100 and should not be accessible to the general public, the signal processing board 250 (TSPB) having received the flash ROM update command is returned to the operator. It is a process to check whether the operator is allowed access by querying password.

When the operator correctly inputs a predetermined password, the signal processing board 250 (TSPB) confirms the authentication state by sending a predetermined message indicating that authentication has been made to the operator terminal 13 again.

When the authentication is completed in step S440, the operator transmits the update data of the flash ROM through the terminal 13 (S450). That is, the flash ROM update data is transmitted from the operator's terminal 13, and the operator stores the flash ROM update data in a data storage medium such as a diskette, and moves to the terminal of the subscriber of the nearby public telephone network 11, Flash ROM update can be performed from.

The signal processing board 250 (TSPB), which has received the flash ROM update data from the operator in step S450, transmits the update data again through the high speed switching device 70 and the LOMS matching device 60: ONAS. ), And the network operation management device 80 (LOMS) again transmits a flash ROM update command and update data to all signal processing boards (TSPB) managed by the network operation management device 80 (LOS).

That is, since the plurality of telephone network matching devices 10 may be used in the mass communication processing system 100, only the flash ROM of the telephone network matching device 10 to which the operator is currently connected should not be updated. Therefore, once the flash ROM update data is sent to the network operation management device 80, the network operation management device 80 transmits the flash ROM update data to all the telephone network matching devices (TNAS). Flash ROM update data is transmitted to the signal processing board (TSPB).

Each signal processing board (TSPB) receiving the flash ROM update data in step S460 transmits a flash ROM update command and update data to the corresponding subscriber modem access board (TDLB) through an interprocessor communication link 103 (IPC link) (S470). ).

The microprocessor 320 of the TDLB receiving the flash ROM update data updates the corresponding flash ROM by using the received flash ROM update data (S480).

In more detail, the microprocessor 320 of the TDLB receiving the flash ROM update command through the IPC link 103 has each flash ROM commonly connected to its own address bus. Outputs the flash ROM selection address. At this time, all the flash ROMs can have the same selection address as their own, and at the same time, the update operation can be performed in all the flash ROMs.

In addition, the microprocessor 320 of the subscriber modem access board (TDLB) outputs the update data of the flash ROM through its data bus, thereby providing the update data to the flash ROM.

In other words, the entire batch of flash ROM updating is performed automatically without the need for the cumbersome procedure of removing the flash ROM, inputting data, and remounting.

Of course, after the update of the flash ROM is finished, the microprocessor 320 of the subscriber modem access board (TDLB) reactivates the corresponding subscriber modem access board (TDLB), so that it can be newly operated by the updated data.

As described above, when the present invention is used, the operator can collectively update all flash ROMs used in the subscriber modem access board (TDLB) by using any terminal subscribed to the public telephone network 11, The time required for updating the flash ROM is saved, and there is an effect that it is possible to provide a better service quickly.
