TCTS Service

The Computer Time Service (TCTS) system in Taiwan was developed by utilizing industrial Personal Computer (IPC) to protect it against corrosion, moisture, dust, and to make maintenance simply. An embedded PC bus level time code generator, which is synchronized to Inter-Range Instrumentation Group (IRIG) B code, is used to provide both a source of time data and time maker for measuring the path delay. The "European Telephone Code" is modified into TCTS time format to match our needs such as Lunar Calendar especially. Two modes, One-way and Loop-back, are operated. The propagation delay was measured precisely and compensated for one-way mode, thus the measured time correlation between TL and Tai-Chung (about 200km away to TL) is better than 2 ms after the compensation. Now, we have launched 2 TCTS systems with 8 lines, 5 speeds via the telephone line for public.
