Method for referencing LAN port state operating connection management of main function unit in WB-DCS

摘要

PURPOSE: A method for referring LAN port state information when managing connection of a main function unit in a wide-band digital cross-connection system is provided to allot state information reference of a LAN port to a shared memory area, thereby letting a communication module be fully responsible for data transmitting and receiving function. CONSTITUTION: MFU(Main Function Unit) LAN port state information is loaded on a system shared memory(S531). An upper process transmits data to a CMFU(Central Main Function Unit) communication module and waits for receiving the process result(S510,S511). If the upper process confirms receiving of the data, the CMFU communication module reads the system shared memory for deciding a LAN port of an active state for connecting with an MFU to process the data of the upper process(S520,S521). The CMFU communication module is connected with the MFU through the decided LAN port for transmitting the data of the upper process and receiving the process result to be reported to the upper process(S522-S524).
