PARALLEL DUAL-BUS OPERATION METHOD AND SYSTEM FOR MAINTENANCE AND ADMINISTRATION IN EXCHANGE SYSTEM

摘要

PURPOSE: A method for operating a maintenance-use dual-parallel bus in an exchange system and a system thereof are provided to enable the maintenance part to efficiently manage the status of each part, and correctly to detect the chip with error as well as to provide the system with a simplified signaling structure among a number of parts. CONSTITUTION: In a maintenance system of an exchange system consisting of a maintenance part(100) and the 1 to 12 chip blocks(CHIP0-CHIP11), the maintenance part(100) and the first chip block(CHIP0) are connected through the first bi-directional transmission-use bus(MA-BUS). The maintenance part(100) and the twelfth chip block(CHIP11) are connected through the second bi-directional transmission-use bus(MS-BUS). The first through twelfth chip blocks(CHIP0-CHIP11) are connected in series, entirely through the loop.
