Turnkey Telecommunication systems are installed in railway projects. District transmission system is built along the railway. Transmission systems are collective networks of fiber optic cables and radio links. Main target of the system is to constitute a network between railway centers (stations, control centers, technical buildings, dispatcher phones, dispatcher panels etc.).
SDH and DWDM technology is used on data and voice conduction equipment in transmission systems. This technology contains internationally well-accepted structure. Transmission networks, depending on being closed or open, are met EN 50159-1 or EN 50159-2 railway safety standards.
GSM-R system is built especially on ERTMS applications. GSM_R network, installed along the railway route, provides data and voice communication. On-board system’s integration has vital effects in Level 2 signalization systems.
