The Master Time Center controls clocks, synchronizes computers to exact time, serves as a time reference on the LAN, switches time controlled electrical loads, supplies time information in various formats and supervises the mains frequency. The MTC has been optimized to offer the best possible reliability and flexibility, in order to produce specific and flexible system-solutions for time distribution, in industries, airports, railways, radio-TV stations, hospitals, power stations and scientific laboratories. The reliable, internal bus system (2-wire), the intelligent function modules, the centralized operation by means of user friendly menus, the comprehensive software for system management as well as many other outstanding features distinguish the MTC system from conventional time centers.
