Focus on network reliability: Power and infrastructure

To ensure the reliable operation of a telecommunications network, power and building systems must be in place, engineered correctly, and well maintained. The Power Quality Resource System (PQRS) supports power systems and other elements of the network infrastructure vital to network reliability programs of the AT&T Network Services Division (NSD). Using best current methods and tools, PQRS delivers a product of “world-class” standards, as evidenced by its absence of defects. This paper describes how PQRS was developed and applied to make AT&T's power and infrastructure provide the most reliable telecommunications network in the world.
