Every telecommunication line that is used for train operation and railroad management has been concentrated on the control center. The control center dispatches instructions to local slave and following their feedback data, the center could regulate the operation of trains and provide customer with various services. With the advent of 10Mbps Ethernet in 1980’s, data networks are introduced for control circuits that consists of metallic cable and MODEM. Moreover, recently introduced KTX system increases the frequency of train operation. To overcome the problems of transmitting large capacity of data such as Video or ERP through the limited conventional telecommunication lines, the introduction of the Ethernet service is essential that utilizes packet data when transmitting and receiving. This paper discusses on the quantitative analysis of the appropriate telecommunication channel quantity and bandwidth especially under IP network circumstances concentrating all telecommunication line on the control center.
