ＩＤＳ—２０００综合数字通信系统借鉴了现有的光纤环路系统、程控交换系统和ＳＤＨ的优点（包括光纤环路系统的光纤远端放号功能、程控交换机的本地交换功能及ＳＤＨ的自愈组网、一步复用和网管开销丰富等优点），并弥补了这些系统现阶段在电力通信专网中应用的不足。文中就该系统与ＳＤＨ在电力通信各级专网中的实用性、组网（尤其是光纤自愈环网）问题以及组网方式等方面进行了分析、比较。
The IDS-2000 integrated digital communication system draws on the advantages of the existing optical loop system, program-controlled switching system and SDH (including the optical fiber remote end numbering function of the optical fiber loop system, the local switching function of the program controlled switch, and the self-healing group of SDH Network, one-step multiplexing and network management overhead and other advantages), and make up for the lack of application of these systems in the power communication network at this stage. The paper analyzes and compares the practicality of the system and SDH in the private network at all levels of power communication, the networking (especially the fiber self-healing ring network) and the networking mode.
