音频、数据和视频服务正对网络可靠性提出更关键的需求,特别在今天高竞争的通信市场中。20多年前,电源不断地迁移,电源由无备用转变为有备用,当时主要传输的为视频信息,这样,这种备用电源提供了可靠性和顾客满意度的改善。20年前,备用的和无备用的电源受模拟电路的控制,几乎任何的通信线路均增加了成本和复杂性。一个现代的宽带电源采用了数字逻辑和微处理控制器,使增设通信功能(包括自助实用程序、诊断和智能警报)更便于实现。此外,现 Audio, data and video services are posing more critical needs for network reliability, particularly in today’s highly competitive communications market. More than 20 years ago, power was constantly migrating and power was switched from standbys to standbys. At the time, the primary transmission was video information, so that backup power provided reliability and customer satisfaction improvements. Twenty years ago, spare and spare power was controlled by analog circuits, adding cost and complexity to almost any communication line. A modern broadband power supply employs digital logic and microprocessor controllers that make it easy to implement additional communication features, including self-service utilities, diagnostics, and smart alerts. In addition, now
