Abstract: With the renewal of railway transmission system equipment and the expansion of network scale, problems such as unstable internal communication between network elements and inefficient network management O&M have become increasingly prominent. This paper studies the transmission system ECC principles and optimization rules. Based on the ECC current status analysis of the Wuhan-Guangzhou high-speed railway transmission system, the ECC optimization scheme is formulated and implemented. The scheme effectively improves the stability and the network management O&M efficiency of the transmission system.

Key words: ECC, transmission system, network management
