Railway Multi-service Communication Backbone Network Solution
Traditional railway communication backbone networks adopt SONET/SDH or pure Ethernet to carry various data services including PIS/PA, BAS, FAS, CCTV, IT, ISCS and video conference services, while separate signal networks transmit signal control information such as CBTC and CTCS. With technological advancement, the convergence of signal services and data services has become a mainstream application trend.
