Harm of Y2K to Programmable Electronic Switching System(ESS) and Countermeasures for Solving this Problem Y2K问题对程控交换机系统的危害及解决对策
In recent years owing to the development of microprocessor technology, the small size SPC ( Stored Program Control ) electronic switching system has been widely used. 近期,由于微处理机技术的发展,使小型程控交换机得到了广泛的应用。
Photon switching technology is a fundamental solution to the speed unmatch between optical fibre system with high transmission speed and electronic switching system with slow switching speed. 光子交换技术是解决高速的光纤传输系统和低速的电子交换系统(ESS)之间速度失配的根本措施。
