详细说明： This Generic Requirements document (GR) presents minimum spatial and environmental criteria for all new telecommunications equipment used in Central Offices (COs) and other environmentally controlled telecommunications equipment spaces. These criteria were developed jointly by Telcordia and industry representatives. They are applicable to switching and transport systems, associated cable distribution systems, distributing and interconnecting frames, power nequipment, operations support systems, and cable entrance facilities. Com pliance with these requirements may increase network robustness, simplify equipment installation, and promote the economical planning and engineering of equipment spaces. Telecommunications equipment, by nature of its physical installation in a building, may be exposed to environmental stresses. The generic criteria presented in the following sections are intended to help avoid equipment damage and malfunction caused by such things as temperature and humidity, vibrations, airborne contaminants, minimize fire ignitions and fire spread, as well as provide for improved space planning and simplified equipment installation. This document provides only those requirements related to the physical aspects of equipment-building interfaces, including physical dimensions and environmental performance criteria. Additional design requirements, including functional, electrical, and reliability requirements, may be found in other requirements documents. ...展开收缩
