程控交换(Stored Program-Controlled Switching System)与机电式的交换系统相比具有很大的优越性。它能适应各种复杂的通信网,可以方便地与各种不同制式、不同型号交换机连通;它本身可以提供多种新业务,实现交换系统以至通信网的维护、管理集中化与自动化,程控交换机具有很高的可靠性;随着微电子技术的发展,程控交换机的体积、耗电以及机房面积日益减少;特别是程控交换系统可以很好地适应新技术的发展,如对光纤通信技
Program-controlled switching (Stored Program-Controlled Switching System) compared with the electromechanical switching system has great advantages. It can adapt to a variety of complex communications network, you can easily with a variety of different models, different models of switches connected; itself can provide a variety of new services, to achieve the exchange system and communications network maintenance, management of centralized and automated, program-controlled switches With high reliability; with the development of microelectronics technology, program-controlled switches, volume, power consumption and the engine room area is decreasing; especially the program-controlled switching system can adapt well to the development of new technologies, such as optical fiber communication technology
