DEFINITIONS OF COMMUNICATIONS EQUIPMENT SITES CHAPTER 3: COMMUNICATION SITE BUILDING DESIGN AND INSTALLATION
TABLE 3-1 STANDARD DEFINITIONS OF COMMUNICATIONS EQUIPMENT SITES (CONTINUED)
Site Type Description Notes
Vault An enclosure that houses communications equipment and
ancillary systems only and is fully or partially buried in soil.
The vault supports personnel only on a limited basis for
installation and maintenance functions.
Example: Similar to a cabinet/enclosure, except the
enclosure is buried below ground level.
Rack A standard equipment rack used for supporting
communications equipment to be installed in an existing
Building or Shelter.
Example: (See Figure 3-3) A radio rack installed in an
existing building or shelter to provide an added function to
the existing site. A standard rack is intended for indoor
installation only in buildings or shelters.
Pre-fab shelters, cabinets, and vaults may have
equipment fully or partially installed prior to
building shipment, requiring additional building
specifications to allow lifting with equipment
installed. Weight and size must be considered if the
site has limited access. For shipping, these structures
must meet strict dimensional requirements,
including protrusions such as HVAC, RF entry
assemblies, or AC entrances. In the US, state
certification may be required if pre-fab buildings are
manufactured in a different state than deployed.
(Similar requirements regarding out-of-state or
province manufacture may also apply in nondomestic
situations.)
