areas, and standardization of common user requirements. Select the most practical
cable/wire distribution system, consistent with facility size and function, current and
projected communications and information systems requirements, the Comprehensive
Interior Design (CID) concept, and the need for flexibility to accommodate f uture
additions or rearrangement. The selection should consider not only the
communications and information systems wiring systems, but also wiring to
accommodate electrical convenience outlets. Consideration will be given to overhead
and in-floor systems including infinite access/raised floors. On-floor (under -carpet)
systems can be considered only in facility alteration projects and will not be used in new
facility construction.
Note: Cabling carrying classified data through an uncontrolled access area is usually
required to be visible unless some other protection method, such as encryption, is used.
G-3.2.2 Communications Systems. The building communications systems must
support the user's current and future voice, data and video requirements. The
communications and information end equipment will include local area networks, secure
voice and data systems, network management and control, packet and circuit switching,
and premise and sensor equipment, desktop instruments and workstations, as well as
communications cabling duct, and equipment rooms and closets which must be sized
and engineered to support this equipment. Cables can be optical fiber, coaxial, or
twisted-pair, and are considered part of the building assets. In administrative areas,
provide numbered outlet jacks for voice and data service, using category 5 wire or
better. Provide outlets as required, except in administrative areas exceeding 93 square
meters (1,000 square feet) of contiguous net office area (usable office space exclud ing
administrative support area). In such areas, provide an outlet with two jacks, one for
telephone and one for data service, for every 4.5 square meters (48 square feet) of net
floor area (usable office space including administrative support space). Consider
providing dual ports, one for voice and one for data, for every category 5 drop. The
Wing can approve requirements for additional outlets and jacks (such as secure voice,
or non-administrative data). Jacks and connector terminations must be consistent with
the wiring. Ensure adequate equipment grounds. Cable television (CATV) needs
should be addressed as part of prewiring in accordance with AFI 64-101, Cable
Television on Air Force Bases.
G-3.2.3 Communications Equipment Rooms (CER) and Telecommunications
Closets (TC):
G-3.2.3.1 Each building [>465 square meters (5,000 square feet) of gross floor area]
should have a CER. Ground floors greater than 1,022 square meters (11,000 square
feet) of net floor area (NFA) should also have a TC per 929 square meters (10,000
square feet). Each floor greater than 929 square meters (10,000 square feet) should
have a TC. Large floors should have a TC for every 929 square meters (10,000 square
feet).
G-3.2.3.2 ANSI/ TIA/EIA -569 requires one telecommunications closet/intermediate
distribution field per floor for up to 1,022 square meters (11,000 square feet). TIA/EIA -
