Remote Flash ROM Update of Subscriber Modem Access Board in High Capacity Communication System

摘要

The present invention relates to a flash ROM remote update method of a subscriber modem access board in a large capacity communication processing system, wherein a flash ROM used for a subscriber modem access board (TDLB), which is a function board of a telephone network matching device of a large capacity communication processing system, is remotely accessed. It is to update.;In the present invention, the operator inputs an access code of the corresponding mass communication processing system using a terminal, and when the access code is transmitted to the signal processing board (TSPB) of the telephone network matching device, the signal processing board provides a predetermined initial screen to the terminal. The transmitting step, the operator transmits the update command of the flash ROM using the terminal, the signal processing board (TSPB) receiving the update command of the flash ROM communicates with the terminal to authenticate whether the operator is permitted access, authentication When this is completed, the operator transmits the update data of the flash ROM through the terminal to the signal processing board, and the update data is transmitted to the network operation management device (LOMS), and the network operation management device again processes all signals managed by the user. Transmitting update data to the board, each signal processing board being connected via a predetermined IPC link. Sending the updated data to the party modem connection board, and;The microprocessor of the subscriber modem access board is configured to update the corresponding flash ROM by using the received flash ROM update data.
