通用访问平台的范围是定义一个机械外壳，为电气和机械部件提供物理支持，并为这些内部部件提供外部保护。间隙外壳规范旨在定义足够的机械和电气细节，以便外壳制造商可以类似地建造间隙外壳。本规范涵盖了足够用于机械安装、端口、环境细节、材料和热性能的外部细节。本规范还旨在涵盖足够的内部细节，以便内部模块可以构造成适合外壳内部。本规范旨在促进现有和未来的各种技术。本规范无意定义新技术的使用- 案例或重新定义现有技术，而是实现对这些技术的物理封装和保护。

The scope of the Generic Access Platform is to define a mechanical housing that provides physical support for electrical and mechanical components and protection from the outside world for those internal components. The GAP Enclosure specification is intended to define sufficient mechanical and electrical details such that it can be similarly constructed by housing manufacturers. The specification covers external details sufficient for mechanical mountings, ports, environmental details, materials, thermal capabilities. The specification is also intended to cover sufficient internal details such that internal modules can be constructed to fit inside the housing. The specification is intended to facilitate various existing and future technologies. The specification is not intended to define new technologies use-cases or to re-define existing technologies, but rather to enable the physical enclosure and protection of those technologies.
