It provides the latest criteria (2016) for analyzing Electronic Equipment Cabinets used in a variety of outside plant environments and applications, including wireless. It includes proposed functional design criteria, generic mechanical and environmental requirements, desired features, and performance tests. Issue 5 was developed with the input of more than a dozen national and international users, suppliers, manufacturers, and installers of Electronic Equipment Cabinets.
