Telcordia GR-487

Telcordia is a telecommunications research and development company that defines and documents telecommunication standards. Telcordia GR-487-CORE standard specifies a suitable environment to house electronic and passive equipment in cabinets or enclosures in an Outside Plant environment. Most enclosures for wireline and wireless applications will require GR-487-CORE. GR-487 covers cabinets and enclosures deployed in the Outside Plant (OSP) environment. The range of enclosures include; wireline electronic equipment cabinets (DSLAM, DLC, cross-connect), wireless cabinets (backhaul switches, battery backup, base station transceiver, E-911 Location Measurement Unit, power amplifiers), field retrofit & adjunct cabinets, and power pedestals (housing for AC commercial power, battery backup).


NEMA Ratings

The NEMA standard on outdoor enclosures and cabinets provides general information on the definitions of NEMA Enclosure Types to architects, engineers, installers, inspectors and other interested parties. Purcell Systems manufactures outdoor enclosures and cabinets to meet both NEMA 3 and NEMA 3R ratings. Although the NEMA standard supports a range of NEMA ratings from 1 through 12, most enclosures for wireline, wireless, and energy applications require NEMA 3 or NEMA 3R ratings. Most general industrial applications will require NEMA 3 or NEMA 4 variants.


ETSI EN 300 019 - Environmental Engineering (EE)

The European Telecommunications Standards Institute (ETSI) produces globally-applicable standards for Information and Communications Technologies (ICT), including fixed, mobile, radio, converged, broadcast and internet technologies. ETS 300 019 is concerned with environmental conditions and environmental tests for telecommunications equipment.



EIA 310 D Standard

EIA-310 is a specification for what is often called the “standard rack”. This specification standardizes several important features of 19″ racks, such as the Rack Unit (RU or U), vertical hole spacing, horizontal hole spacing, rack opening and front panel width. The specification also sets tolerances on each of these dimensions.

The EIA-310 specification has been the 19″ racks standard for equipment for 50 years. Despite this, RackSolutions believes that the items that the specification does not cover is the real reason for the industry wide incompatibility we now face. Rack features such as hole type, rack mounting depth, front and rear space, and obstructions between front and rear rails are the cause of real rack headaches.


UL 60950-1 Standard
