Communication Division Specifications
1. Background/Overview
1.1. To minimize the long-term cost of the infrastructure, ensure interoperability and interface capability, these local standards are established and may only be changed when approved in writing by the Communications-Computer Systems Officer (CSO). These standards are intended to promote common skills among maintenance personnel throughout the base and to minimize the necessity for excessive spare parts and variations in telecommunications equipment. Revisions to this document will be prepared and distributed by the 377 Communications Division (377 MSG/SC) when higher headquarters guidance, United States Air Force (USAF) communications standards, or other contributing agency standards warrant changes. Additionally, 377 MSG/SC recognizes the inherent need to maintain close interaction with Base Civil Engineering and the Army Corp of Engineers on all project issues and invite comments or recommendations for changes to this document.
2. General Purpose
2.1. The purpose of this instruction is to provide design criteria for planning telecommunications cabling and distribution systems in building construction and renovation efforts. Pre-wiring shall be included in all Military Construction (MILCON) projects to include renovations accomplished in accordance with Air Force ETL 02-12 Communications and Information System. All pre- wiring must comply with the ETL 02-12, UFC 3-580-01, and this instruction. Compliance with these instructions will improve maintenance by establishing a standard for communications systems facility. Department of Defense (DOD) publications direct the use of commercial standards whenever they meet DOD needs. The commercial standards referenced in ETL 02-12 and UFC 3-580-01 shall be followed along with this instruction.
2.1.1. This guidance is for all MILCON, Cabling Infrastructure and Building Renovation projects with Kirtland AFB boundaries, whether managed/funded by Base Civil Engineering or Base Communications.

14 Telecom Outlets
14.1 In general office areas, use a quad modular telecommunications outlet, with four 8pin/8 position CAT 6 or better modular Uniform Service Order Code RJ-45 type jacks mounted in a single face plate (two for voice/two for data) in a factory made assembly. All wall outlet components shall have a removable outer bezel with molded labeling to identify the outlet usage (see Figure 1). Communication jacks installed in or under the floor will have dust covers installed on the individual jacks. Enclosure covers with seals will be used to prevent moisture and debris from entering the enclosure. All inside wire used for telecommunications outlets shall be four pair, 24 American Wire Gauge (AWG), solid copper conductor, CAT 6, Underwriters Laboratories (UL) tested and certified with a green outer shell.
14.2 Each cable shall be dedicated to one device or outlet only.
14.3 Only plenum rated cable may be used whenever cable is installed and exposed within air circulation areas.
14.3.2 Telecommunication outlets shall be mounted 18" above the finished floor, to the centerline of the cover plate, unless noted otherwise.
14.3.3 Place phone/data/Local Area Network (LAN) outlet jacks along every wall or one every 8 feet apart or for every 40 square feet; whichever provides a higher outlet density. All other locations will be provided with an outlet density as determined and approved by 377 MSG/SCXP.
14.3.4 Outlet Jacks will be labeled in accordance with Figure 1 to provide critical information for maintenance actions.

15 Other Considerations
15.1 Security
15.1.2 A controlled and secured access cypher keypad lock on the TR is required to allow 24-hour uninterrupted access by authorized technicians. This cypher lock also provides keyed entry for facility managers. Only authorized personnel by 377 MSG/SC will possess room combination.
15.1.3 For TRs storing inspectable SIPRNET, an exterior door look meeting STIG V-31267 (Version: IS-02.01.01) shall be installed.
15.1.4 Classified requirements may vary and shall be taken on a case-by-case basis.
15.2 Operational Environment
15.2.2 Temperature/Humidity. A temperature controlled environment is required IAW Air Force AF ETL 02-12, Para. 8.3.3.2.3 in all TRs. Provide heating, cooling, and fresh air appropriate for the equipment housed. Maintain a positive pressure inside the room to reduce the entry of dust. Normal operating ranges should be as locally established for employee comfort (typically between 65°F to 78°F. There are no special relative humidity requirements. However, in order to minimize static discharge and condensation it is recommended that the relative humidity be between 20% and 60%.
15.2.3 Lighting: Sufficient lighting will be provided in all TR areas to promote a safe and acceptable work area. Switched lighting will be provided in all TR areas, adequate to promote work with small fiber items and miniature lettering devices. Maintain a minimum of 12" clearance between fluorescent “ballasted” light fixtures and all cable runs and cable devices. Provide a minimum of 538 lux (50 foot-candles) of illumination measured 1 meter (39 inches) above the finished floor.
15.3 Geospatial Mapping / Surveying
15.3.2 Geospatial Mapping / Surveying data is required to be submitted for all work outside the bounds of footprints of buildings. This includes all outside plant infrastructure features and communications pathways that are installed / modified.
15.3.3 Example of Outside Plant features include manholes, vaults, pedestals, underground cables, marked direct buried splices, terminals etc.
15.3.4 Examples of Communications pathways include duct routes, direct-buried cable, and communication pathway entry points on building exterior walls that lead to interior building entry terminals, etc.
15.3.5 Geospatial Mapping / Surveying shall be accomplished in accordance with Appendix B - GUIDANCE FOR GEOSPATIAL DATA
15.4 Classified Systems (Secure Internet Protocol Router Network (SIPRNET) and Defense Red Switch Network (DRSN)).
15.4.2 Customers must identify classified message traffic or telephone requirements, and coordinate all requirements with the 377 MSG/SC Plans and the Information Assurance Flights to ensure proper compliance measures are attained.
15.5 Modular Furniture.
15.5.2 Telephone and LAN wiring systems in areas with pre-wired workstations, furniture systems or modular walls must have sufficient flexibility and connectivity to enable rearrangement without modification to the permanent communications wiring in the facility. This is facilitated with modular furniture by including supporting faceplates for standard CAT6 jacks. These jacks will be label under the same standard as wall jacks (See Figure 1). Permanent connections involving modular equipment/furniture are prohibited; there should only be one CAT 6 jack between the TR and the customer’s equipment.
Suitable patch cords and connectors must be provided. Patch cords will be permanently labeled with the corresponding outlet number and will be included in installation.
15.6 Periodic, Final Inspections, Testing and Documentation.
15.6.2 All telecommunications cable will be certified and tested utilizing test equipment in accordance with EIA/TIA standards with written test result to be provided to the 377 MSG/SC. Where deficiencies of any type are discovered upon testing, the contractor will make all necessary repairs, including replacement if necessary, at no cost to the government.
15.6.3 Two groups of acceptable digital records must be provided to 377 MSG/SC prior to final acceptance: (1) cable certification records (2) Revised drawings which reflect the actual “as built” conditions (preference to Visio files)
15.6.4 All communications drawings will be geospatial referenced and include the conduit, innerduct, cable types, cable count, cable size, and length. All manholes and pull boxes will have complete butterfly details to include geospatial referenced location, entry points, grounding, bonding, racks/ladders, or other equipment installed. See Appendix B for more information on GPS survey requirements.
15.6.5 377 MSG/SC personnel will conduct in-progress inspections during construction. The general contractor performing the work is solely responsible for scheduling inspections and providing response to the government for inspection findings. These inspections will be scheduled with 377 MSG/SC before backfill or installation of walls. Trenches may be inspected to verify conduit size, quantity, cable type, earth cover compliance, and updated "red line" cable record or contract drawings.
15.6.6 All installed cables will be tested by the installer, and may be in the presence of 377 MSG/SC personnel or its representatives. Baseline test records will be provided to the 377 MSG/SC in printed and digital format.
