FOREWORD

The Unified Facilities Criteria (UFC) system is prescribed by MIL-STD 3007 and provides planning, design, construction, sustainment, restoration, and modernization criteria, and applies to the Military Departments, the Defense Agencies, and the DoD Field Activities in accordance with USD (AT&L) Memorandum dated 29 May 2002. UFC will be used for all DoD projects and work for other customers where appropriate. All construction outside of the United States, its territories, and possessions is also governed by Status of Forces Agreements (SOFA), Host Nation Funded Construction Agreements (HNFA), and in some instances, Bilateral Infrastructure Agreements (BIA). Therefore, the acquisition team must ensure compliance with the most stringent of the UFC, the SOFA, the HNFA, and the BIA, as applicable.

UFC are living documents and will be periodically reviewed, updated, and made available to users as part of the Military Department’s responsibility for providing technical criteria for military construction. Headquarters, U.S. Army Corps of Engineers (HQUSACE), Naval Facilities Engineering Systems Command (NAVFAC), and Air Force Civil Engineer Center (AFCEC) are responsible for administration of the UFC system. Technical content of UFC is the responsibility of the cognizant DoD working group. Defense Agencies should contact the respective DoD Working Group for document interpretation and improvements. Recommended changes with supporting rationale may be sent to the respective DoD working group by submitting a Criteria Change Request (CCR) via the Internet site listed below.

UFC are effective upon issuance and are distributed only in electronic media from the following source:

• Whole Building Design Guide website https://www.wbdg.org/ffc/dod.

CHAPTER 1 INTRODUCTION

1-1 PURPOSE AND SCOPE.

This UFC provides design criteria for telecommunications spaces, pathways, cabling, and interconnecting components necessary to support the infrastructure for voice, data, video, smart buildings, and Internet of Things (IoT) systems. It does not address the design and specifics of the technologies that employ information communications technology infrastructure. “Video systems” includes the necessary infrastructure for closed circuit television (CCTV); community antenna television (CATV), commonly referred to as cable TV; video teleconferencing (VTC); and video walls.

1-2 REISSUES AND CANCELS.

This UFC reissues and cancels UFC 3-580-01, 1 June 2016; MIL-HDBK-1012/3, dated 31 May 1996; and Army publications Installation Information Infrastructure Architecture (I3A),” dated February 2010, “Installation Information Infrastructure Architecture (I3A) for Outside Plant Only,” dated November 2017, “Outside Plant Design and Performance Requirements (OSPDPR),” dated February 2009, “OSPDPR Addendum 1 – Core and Distribution Fiber Sizing Criteria for Installation Campus Area Network Design and Implementation,” dated September 2014.

1-3 APPLICABILITY.

This UFC applies to planning, design, construction, sustainment, restoration, and modernization of DoD-owned facilities. It applies to all methods of project delivery and levels of construction as defined by UFC 1-200-01, Section 1-3.

1-4 GENERAL BUILDING REQUIREMENTS.

Comply with UFC 1-200-01. UFC 1-200-01 provides applicable model building codes and government-unique criteria for typical design disciplines and building systems, as well as accessibility, antiterrorism, security, high performance and sustainability, and safety requirements. Use this UFC in addition to UFC 1-200-01 and the UFCs and government criteria referenced within.

1-5 CYBERSECURITY.

All facility-related control systems (including systems separate from a utility monitoring and control system) must be planned, designed, acquired, executed, and maintained in accordance with UFC 4-010-06, and as required by individual Service implementation policy.

1-6 Governing Criteria for Electrical Systems.

UFC 3-501-01 provides the criteria for electrical systems, delineates among electrical-related UFCs, and refers to UFC 3-520-01 for interior electrical system requirements.

1-7 Modernization Within Existing Facilities.

Modernization of information communications technology systems within existing facilities solely for the purpose of meeting design criteria in this UFC is not required.

1-8 Activity Specific Telecommunications Managers.

Throughout this UFC, the term “Telecommunications Manager” refers to:

• Army – the Network Enterprise Center (NEC) or the Information Officer (G6, S6, J6)

• Navy – a group of individuals with responsibilities as shown in Figure 6-1.

• Marine Corps – G6.

• Air Force – A6.

1-9 GLOSSARY.

Appendix B contains acronyms, abbreviations, and terms.

1-10 References.

Appendix C contains a list of references used in this UFC. Publication dates are not included; the most recent issuances apply unless otherwise specified.

CHAPTER 2 DESIGN REQUIREMENTS

2-1 General Guidance.

Design information communications technology infrastructure to meet the needs of the activity and supporting facilities in accordance with this UFC. Final drawings and specifications for design-bid-build and design-build projects must be stamped by a Building Industry Consulting Service, International (BICSI), Inc., Registered Communications Distribution Designer (RCDD).

Because construction phases may be concurrent with design in design-build projects, and because multiple phases of construction may be approved, the final documents for each construction phase must be stamped when approved.

2-1.1 U.S. Government- (USG-) Designed Projects.

On USG-designed projects (in-house design), the USG designer must:

• Obtain the approval of the Service-appointed information communications technology agent at the beginning of design in accordance with regulations, policies, memorandums, and guidance.

• Ensure that the bid documents require an RCDD stamp on the contractor’s telecommunications shop drawings submitted for approval.

• Ensure final drawings and specifications for design-bid-build and design-build projects have been reviewed and approved by a BICSI RCDD.

2-1.2 Small Scale Projects.

Small scale projects limited to adding work area outlets from existing telecommunica-tions rooms do not require an RCDD stamp, provided the work is being accomplished under the technical authority of an RCDD or the USG Information Communications Technology Manager.

2-1.3 Design Elements.

The complexity of Information and Communications Technology (ICT) design requires that the Designer of Record (DOR) engage early to achieve successful outcomes.

Tables 2-1 and 2-2 list expected submissions and when they are due in the process.

These timeframes may be adjusted for fast-tracked or other delivery mechanisms to align with design processes.

2-2 SECURE SPACE INFRASTRUCTURE.

Secure spaces include classified networks such as Secret Internet Protocol Router Network (SIPRNet), Joint Worldwide Intelligence Communications System (JWICS), or National Security Agency Intranet (NSANet). These networks process National Security Information (NSI) and have unique requirements.

2-2.1 RED/BLACK Telecommunications Systems.

All equipment, wirelines, components, and systems that process NSI are considered RED. Equipment, wirelines, components, and systems that process encrypted NSI and non-NSI are considered BLACK. BLACK lines and other electrically conductive materials that egress the inspectable space are potential carriers of compromising emanations (CE) that can inadvertently couple to the RED lines. Various signal line isolation techniques such as separation and filtering are used to protect the signal line, the distribution system, or other fortuitous conductors from conducting compromising signals beyond secure areas.

Apply fundamental RED/BLACK separation in accordance with Committee on National Security Systems Advisory Memorandum (CNSSAM) 1-13 to prevent inadvertent transmission of classified data over telephone lines, power lines, signal lines, and electrical components, circuits, and communication media. Application of RED/BLACK separation establishes areas where equipment that processes classified information (RED) is isolated from areas where equipment processing unclassified (BLACK) is located.

2-2.2 Telecommunications Space.

Account for the space required for equipment rooms and telecommunications rooms and ensure it is adequate to meet separation requirements before floor plans are locked

in. The minimum sizing in this UFC is presented with a single black network and does not account for RED networks and the separations between the racks or cabinets in the space. A telecommunications space that contains equipment for multiple networks such as SIPRNet, JWICS, and NIPRNet all requiring RED/BLACK separation is considered as substantial information technology (IT) electronics which would require use of an equipment room.

2-2.3 Telecommunication Cabling System.

Cabling, patch panels, connector blocks, work area outlets, and cable connectors must be color-coded to distinguish their classification level. If color-coding is not possible, cabling must be clearly marked to indicate classification level. Provide detail sufficient for the security officer to submit and obtain approval from the certified TEMPEST technical authority. Design submittals must document RED/BLACK and checklist items from Intelligence Community Directive (ICD) Tech Spec, including the TEMPEST checklist items specific to telecommunications systems.

2-2.4 Protected Distribution Systems.

Use a protected signal distribution system (PDS) to protect unencrypted NSI that enters an area of lower classification, unclassified area, or uncontrolled (public) area. The PDS must comply with Committee on National Security Systems Instruction (CNSSI) No. 7003. Mount standard PDSs 1 inch (25 millimeters) from walls and other objects.

To prevent obfuscating repairs made to the raceway, paint must not be field-applied.

With prior approval from the Telecommunications Manager, galvanized rigid steel conduit (GRC) or electrical metallic tubing (EMT) may be used in addition to other approved surface mount raceways. Compression-type fittings are required with black epoxy glue applied to prevent tampering and as an aid to visual inspection. GRC compression or threaded fittings may be used with epoxy.

Due to inspection requirements, avoid using PDS whenever possible. To avoid PDS, keep cabling that transmits unencrypted NSI within the protected perimeter.

2-2.5 Alarmed Carrier.

An alarmed carrier may be used as an alternative to a physical PDS. Refer to CNSSI 7003.

2-2.6 Sensitive Compartmented Information Facility (SCIF) and Special Access Program Facility (SAPF).

Refer to UFC 4-010-05 and CNSSAM 1-13 RED/BLACK installation guidance.

2-2.7 Stand Alone SIPRNet Terminal Space.

Paragraphs 2-2.7.1 through 2-2.7.3 describe where a SIPRNet workstation outlet is required in a facility that lacks secure telecommunications spaces.

2-2.7.1 Pathways.

Provide PDS between the telecommunications enclosure and the lockable workstation outlet. Maintain a 6-inch (150-millimeter) separation between the workstation outlet and any other workstation outlet.

2-2.7.2 Telecommunication Equipment Enclosure.

When secure telecommunications spaces in a facility build-out are not equipped, specify a GSA-approved information processing system (IPS) container to house electronics that will permit a black-to-red transition. The container door must be specified and equipped with a Federal Specification FF-L-2740 lock.

2-2.7.3 Workstation Outlet Enclosure.

Enclosures must not have knockouts and must be metallic 16 gauge or greater. Hinges must be continuous and non-removable. Enclosures must not be field-painted, but may have factory-baked enamel or be galvanized. Enclosures must be continuously sealed with epoxy or welding of all joints except the hinged opening. Non-removable hasps must be equipped that will accept a lock meeting FF-P-110-J. Enclosures for workstation outlets must be GSA-approved.

2-3 SYSTEM DESIGN REQUIREMENTS.

Provide a complete, standards-based, flexible information communications technology design, including telecommunications spaces, pathways, outlets, connectors, cabling, grounding, bonding, and static protection in accordance with paragraphs 2-3.1 through 2-4.

2-3.1 Telecommunications Spaces.

Provide telecommunications spaces in accordance with Telecommunications Industry Association (TIA)-569. Refer to Figure 2-1.

Note: This UFC uses commercial terminology for spaces in accordance with the TIA-569-E errata sheet (e.g., telecommunications room, equipment room versus distributor room A and B, and telecommunications enclosure versus distributor enclosure).

2-3.1.1 Types of Telecommunications Spaces.

a. Telecommunications Entrance Facility. An entrance facility (EF) is the space housing the point of entrance of the information communications technology service. The EF is also the space where the inter-building backbone and intra-building backbone facilities join. Telecommunication-related antenna entrances and electronic equipment may be located in the EF. The demarcation point between the outside plant (OSP) cabling and the inside plant distribution cabling is the protected entrance terminal (PET). See Chapters 2 and 3 for PET requirements.

The DOR should coordinate with the Telecommunications Manager for additional physical security requirements inside the EF including, but not limited to, colocation cabinet(s) if required for commercial or other carriers.

b. Telecommunications Room. A telecommunications room (TR) is an architectural space designed to contain information communications technology equipment, cable terminations, and cross-connect cabling. It contains the information communications technology equipment for connecting the horizontal cabling with the backbone cabling system. The TR may also function as the telecommunications EF.

c. Equipment Room. An equipment room (ER) is an environmentally-controlled, centralized space for information communications technology equipment that typically houses a main or intermediate cross-connect. Any or all the functions of a TR or EF may be provided by an equipment room.

d. Telecommunications Enclosure. A telecommunications enclosure (TE) is a case or housing for telecommunications equipment, cable terminations, and cross-connect cabling.

Although TEs serve much like TRs, a TE must not replace a TR. TEs may be considered for buildings with fewer than 10 occupants when approved by the COR for contract designs or the Government design lead for in-house designs. The TE is referred to as a distributor enclosure in TIA-569. TEs must meet TIA-569’s requirements for distributor enclosures.

Figure 2-1 Telecommunications Spaces and Cabling

2-3.1.2 Architectural Considerations.

2-3.1.2.1 Location and Access.

Locate telecommunications spaces so that the maximum cable length from the patch panel through the structured cabling system to the furthest outlet does not exceed 295 feet (90 meters). Telecommunications spaces must be dedicated spaces not shared with other non-information communications technology functions (electrical rooms, mechanical rooms, plumbing). Avoid locations that are restricted by building components that may limit expansion, such as elevators, outside walls, or other fixed building walls. Spaces must be capable of expanding on no less than two sides.

Evaluate locations for risk to critical infrastructure (water, dust, electromagnetic impulse (EMI) influence). Locate the telecommunications space away from sources of electromagnetic interference or design the space to mitigate the effects of this interference. Give special attention to electrical power supply transformers, motors and generators, x-ray equipment, and radio or radar transmitters. Locate spaces in an accessible area of the building (e.g., common hallway), but limit access to personnel having an information communications technology requirement or mission. The space must be accessible for delivery of equipment such as network switches, equipment racks, and cabinets.

In renovation projects, avoid rooms containing transformers, air handling units, and similar equipment. If shared facilities cannot be avoided, comply with TIA-569.

2-3.1.2.2 Telecommunication Spaces Sizing and Quantity.

a. Space for working clearances is critical to allow maintenance activities including moves and changes.

b. Size each TR in accordance with ANSI/TIA-568, with the exception that the minimum TR size for DoD buildings is 10 feet, 6 inches by 9 feet (3.2 meters by 2.7 meters) in buildings larger than 5,000 square feet (464.5 square meters) (Figure 2-2).

This will allow a minimum of one spare rack for telecommunication spaces that can be served by one rack to comply with paragraph 2-3.1.5.3 and allows space for equipment mounted on walls.

Adjust the dimensions if vertical cable management for cable longer than shown in Figure 2-2 is required.

Figure 2-2 Minimum Telecommunications Spaces Sizing

c. As best practice, size TRs to approximately 1.1 percent of the area it serves. For example, a 10,000 square foot (929 square meter) area should be served by a minimum of one 10 foot-by-11 foot (3 meter-by-3.4 meter) TR. Divide large floor areas into “serving areas” with TRs for each serving area. Serving area must be no larger than 10,000 square feet (929 square meters) and must not serve more than 20,000 square feet (1,858 square meters). When a TR is designed to serve spaces larger than 10,000 square feet, verify the size of the TR is adequate. Allow for code-required clearances in space allocations.

d. Heating, ventilation, and air conditioning (HVAC) requirements may be substantially affected if additional systems are required in the TR. Consult with the architectural designer or facilities engineer when additional systems requirements (audio visual systems, servers, disk storage arrays) are integrated into the TR.

e. Consider using an ER for areas that exceed 10,000 square feet or for buildings that house substantial IT electronics.

Note: One TR may be adequate for multi-story buildings or in unique facilities. Refer to paragraph 2-3.1.2.5.

f. Ensure adequate space in TRs to accommodate tenant-owned data and information communications technology systems, including FRCS. Support equipment requirements in tenant-installed freestanding cabinets or racks. Total TR space as a percentage of the building’s area must be scaled upward to reflect any increase in horizontal drops to each workspace in buildings with more than the standard number.

Examples may include command and control facilities or health care facilities.

2-3.1.2.3 Floors, Walls, and Ceilings.

For floors, walls, and ceilings in telecommunications spaces, meet the requirements in TIA-569. Do not install suspended ceilings in telecommunications spaces.

2-3.1.2.4 Doors and Windows.

Exterior and interior doors must satisfy fire rating requirements for TRs in TIA-569 and National Fire Protection Association (NFPA) 101®. For security reasons, exterior windows or architectural window equivalents are not permitted

2-3.1.2.5 Multi-Story Buildings and Unique Facilities.

Provide a minimum of one TR per floor. Provide additional rooms when the floor area is greater than 20,000 square feet and/or the total cable distance to the outlet is over 295 feet (90 meters). Serve all information communications technology outlets from the TR located on that floor. Vertically align TRs on successive floors to allow the risers to align on the same walls. In the case of small and unique facilities, a single TR may be adequate for the entire facility. These facilities include, but are not limited to, air traffic control towers, warehouses, firing ranges, and range and weapons towers.

2-3.1.3 Utility Considerations.

2-3.1.3.1 Lighting.

Design lighting for telecommunications spaces in accordance with UFC 3-530-01.

Illumination over aisles should coordinate with overhead runway systems.

2-3.1.3.2 Power.

Provide a dedicated electrical branch circuit panel board for each TR meeting the following minimum requirements: 120/208 volt (V), 3-phase or 120/240V, 1-phase, 24- (or 20- for 1-phase) space panel with a minimum 100 ampere (A) bus rated capacity.

Feed loads within the TR from this dedicated TR panel. Loads must include, but are not limited to, convenience receptacles, dedicated rack or cabinet receptacles, and HVAC systems (including exterior units for split systems). Provide 125V, 20A duplex convenience receptacles at 6-foot (1.8-meter) intervals on-center around perimeter walls.

Unless otherwise specified by the Telecommunications Manager, provide a minimum of one receptacle at each rack. To minimize accidental shutoff, equip power strips with indicator lights, but no integral on/off switch. Provide matching (National Electrical

Manufacturers Association (NEMA) configured) twist-lock type receptacles fed from dedicated circuits in the TR panel or from a busway to power each power strip. Install twist-lock receptacles above the rack or cabinet mounted to an information communica-tions technology cable tray. As some rack- or cabinet-mounted equipment may require more power, consult with the local information communications technology group having jurisdiction to determine exact electrical power requirements for each TR.

2-3.1.3.3 Heating, Ventilation, and Air Conditioning.

Design telecommunications spaces to meet HVAC requirements of TIA-569, including the Class B requirements for temperature and humidity as outlined in American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) Thermal Guidelines for Data Processing Environments. Class B space includes only temperature control. When the IT equipment (ITE) load includes enterprise servers, volume servers, storage products, and other computing environment, the space may be categorized as A4 or A3. TRs will be Class B. ERs may be Class B or Class A4, depending upon the user’s equipment load. Work with the system owner to understand the environmental needs and coordinate them with the full design team.

2-3.1.3.4 Room Climate Control.

a. Provide each TR with its own independent thermostat for climate control, capable of supporting year-round ambient temperature control (24 hours per day, 365 days per year) to protect all installed electronic equipment as defined in TIA-569. The mechanical system designer of record must determine the type of system required to meet the environmental condition requirements for all telecommunications spaces.

Data centers may require a narrower environmental envelope to safeguard equipment function. Do not include heating and cooling systems within TRs on building time clocks or other temperature setback mechanisms. Provide rooms with positive atmospheric pressure to minimize dust when required by system owners or equipment manufacturers.

b. Design cabinets and rows to avoid recirculation of exhaust air into equipment intakes. Specify blanking panels and baffles as needed to mitigate intra-cabinet circulation. Equipment should be arranged into hot and cold aisles when more advanced schemes of cooling are not used.

c. Do not use electrical name plate data for cooling requirement calculations.

Manufacturer heat load data by equipment is best for use in calculating cooling requirements but is not always available. The mechanical designer must determine the amount of cooling required, but will need to collaborate with the telecom designer to understand requirements.

d. Design cooling load capacity to include growth capabilities for IT refresh planning in accordance with ASHRAE 90454. For calculated loads less than one ton (12,000 British thermal units per hour (BTU/hr)), provide a single air conditioning (A/C) unit with space and power capacity to install another identical unit for future load growth.

For loads greater than one ton, install two identical units sized for 50% to 60% of the load each, and provide space and power capacity for an additional identically-sized unit for future load growth. For loads greater than 10 tons (120,000 BTU/hr), and where redundant uninterruptable power systems (UPS) have been installed in the telecommunications space, provide more than two A/C units to meet the N+1 redundancy criteria, where N is the number of A/C units required to meet the load (not less than 2), and 1 is the identically-sized redundant spare. In addition to the one redundant spare A/C unit, provide space and power capacity for one additional identically-sized A/C unit for future load growth. Other redundancy requirements may be required by the mission. Ensure IT, power, and mechanical cooling requirements are aligned with the mission.

e. Utility piping serving telecommunications spaces must not be routed over communications racks or cabinets or electrical panels. Where routing over sensitive areas cannot be avoided, provide all wet and drainage piping with special protection, such as double-wall containment piping or drip pans with leak detection to protect the space below from leakage and/or condensation.

2-3.1.4 Room Contaminants.

Do not install information systems equipment in spaces where moisture, liquid or gaseous spillage, or other contaminants may be present, as defined in TIA-569. Do not design spaces that will have a wet wall that can provide ingress of liquids or potentially require maintenance from inside of the telecommunications space for unrelated utilities.

2-3.1.5 Space Components.

For all ICT components, use manufacturer’s standard catalog products that conform to the latest published industry and technical society standards at the date of contract award. Do not use shop- or field-fabricated components that are not manufacturer's standard catalog products or that do not conform to the industry and technical society standards.

2-3.1.5.1 Plywood Backboards.

Provide backboards in accordance with TIA-569. Fire retardant treated wood must comply with International Building Code, Section 2303.2. Backboards must be fire-retardant-treated wood, bearing the manufacturer’s stamp. Backboards are not required to be painted unless requested by the Information Communications Technology Manager for illumination reflectance. They must display at least one fire-rated stamp after wall-mounted equipment is installed and they are painted. Cover a minimum of two adjacent walls with backboards. Allow 1 foot (305 millimeters) of depth space for wall-mounted equipment when calculating room sizes. If equipment with a known depth greater than 1 foot will be used, also allow for that space and required clearance. When renovating an existing TR that does not have adequate space, size the backboard as large as possible to accommodate wall-mounted equipment.

2-3.1.5.2 Protected Entrance Terminals.

TIA-758 identifies two types of building entrance terminals (BET) -- protected and non-protected. Provide protected entrance terminals (PET) in accordance with TIA-758.

Equip PETs with modules to protect the inside plant cabling and equipment from power surges. Furnish solid state or gas tube modules adequate for all used pairs plus 25%, but not to exceed the total pair count. Provide 110-type insulation displacement connector (IDC) terminal blocks or cable stubs. See paragraph 2-4 for grounding requirements. Refer to Chapter 3 for OSP requirements.

2-3.1.5.3 Equipment Racks.

Provide 19-inch (475-millimeter) floor-mounted equipment racks. A minimum of 36 inches’ (900 millimeters’) space, both in front and behind the rack measured from the equipment, and a minimum side clearance of 36 inches on at least one end of the rack or row of adjacent racks is required. Allow a front-to rear-space of 42 inches (1067 millimeters) to accommodate equipment. Coordinate with the Information Communica-tions Technology Manager to determine the space and weight requirements for the USG-provided active equipment. A four-post rack may be required to support equipment due to weight or mounting requirements. Provide 25% spare rack unit capacity within each rack used. Provide one spare rack for every four used racks, with a minimum of one spare rack per telecommunication space.

In existing facilities with narrow or crowded telecommunication spaces, equipment racks may be wall-mounted with the approval of the Information Communications Technology Manager. Workspace around the cabinet/rack is still required even if the cabinet is mounted 6.5 feet (2 meters) off the floor. Refer to Figure 2-3.

2-3.1.5.4 Equipment Cabinets.

Provide equipment cabinets in lieu of racks where:

• identified by Service-specific chapters in this UFC.

• required by the Information Communications Technology Manager.

• physical security is required, such as to mount secure or mission critical equipment.

• separately controlled access is desired (when multiple systems are collocated within the room).

a. Provide a minimum 24 inch- (600 millimeter-) wide cabinets with cooling fans (when required) and internal rails to support 19-inch (475-millimeter) equipment.

Locate cabinets in rows with front and rear clearance. A minimum space of 36 inches (900 millimeters), both in front and behind the cabinet, and a minimum side clearance of 24 inches (600 millimeters) on at least one end of the cabinet or row of adjacent cabinets is required. When an aisle is against a wall, cabinets should not exceed eight in a row.

b. Design cabinets with 63% mesh doors with blanks and baffling to ensure front-to-rear air flow and avoid intra-cabinet air circulation, unless another cooling method is designed. In instances where other air flow is needed, use manufacturer-approved penetrations and sealing to maintain airflow. For hot and cold aisles, use an airflow scheme engineered for the solution.

Figure 2-3 Wall Mounted or Floor Mounted Cabinet Clearance

c. Coordinate with the Information Communications Technology Manager to determine space requirements for the USG-provided active equipment. Provide 25% spare capacity within each cabinet used. Provide one spare cabinet for every four cabinets used, with a minimum of one spare cabinet per telecommunication space.

d. In existing facilities with narrow or crowded telecommunication spaces, equipment cabinets may be wall-mounted with the approval of the Information Communications Technology Manager. FRCS may require wall-mounted cabinets.

Where space is limited and clearances are affected, use swing-out cabinets. See Figure 2-3.

2-3.1.6 Horizontal and Vertical Cable Management.

Provide horizontal cable management panels above and below each patch panel. The required ratio of horizontal cable management to patch panels is 1:1. Provide vertical cable management between racks and at the end of racks when required to protect, manage, and organize cables. Vertical cable management panels must be a minimum of 6 inches (150 millimeters) wide, and sized based on total anticipated cable plus 50%.

Allow space against the wall for operation of vertical management covers.

2-3.1.7 Ladder and Wire Cable Tray.

Use ladder-type cable trays in telecommunication spaces to provide distribution between the plywood backboard, equipment racks, backbone conduits, and the distribution cable tray. Bond all metallic cable tray sections and bond the cable tray system to the primary bonding busbar (PBB) or secondary bonding busbar (SBB).

2-3.1.8 Copper Pair Patch Panels.

For patch panels, use 8-position, 8-contact (8P8C) modular jacks with rear-mounted 110-type IDC terminations, category rated for the copper cabling being installed, and arrange in rows or columns on 19-inch (475-millimeter) rack-mounted panels. For small projects (fewer than ten users), 19-inch TIA category-qualified wall mounted block or backboard patch panels may be used. Provide T568A jack pin/pair configuration per ANSI/TIA-568. T568B jack pin/pair configuration may be used only if required to maintain uniformity in an existing facility. Provide modular jacks that conform to the requirements of ANSI/TIA-568, rated for use with the installed cable plant. Install unshielded twisted pair (UTP) patch panels in the same rack or in the rack immediately adjacent to the local area network (LAN) equipment to minimize patch cord lengths. Provide a minimum spare capacity of 25 percent.

2-3.1.9 Fiber Optic Patch Panels.

Use patch panel connectors and couplers of the same type and configuration as used elsewhere in the system. Unless otherwise directed, use duplex lucent connectors (LC) or keyed LC connectors on 19-inch rack-mounted panels to support legacy installations.

Provide a 3-foot (0.9-meter) slack loop of fiber within each panel and include strain relief for cables within the panel. Provide proper termination, splice storage, routing, radius limiting, cable fastening, strand storage, and cross-connection in all patch panels.

Install fiber optic patch panels in the same rack or in the rack immediately adjacent to the LAN equipment to minimize patch cord lengths. Provide a minimum spare capacity of 25 percent.

Consider multi-fiber termination push-on (MTP®) factory-terminated fiber optic systems using cassettes to break out fibers. This has many advantages, including factory testing, shorter installation times, future-proofing connection types, and tap port options.

In existing facilities, other connector types may be used to match the current infrastructure with the approval of the Information Communications Technology Manager.

2-3.2 Telecommunications Pathways.

A pathway is a facility for placement of information communications technology cable.

2-3.2.1 Backbone Pathways.

Backbone pathways are structures that conceal, protect, support, and provide access to cables between telecommunications spaces. Examples of backbone pathways include conduit, sleeves, slots, cable trays, telecommunication spaces, and miscellaneous support facilities.

For intra-building backbone distribution, use a minimum of two 4-inch (100-millimeter) conduits between TRs located on the same floor, or a pathway that provides equivalent capacity (e.g., cable tray installed to support backbone and horizontal distribution).

In multistory buildings, use a minimum of three 4-inch conduits, sleeves, or an equivalently-sized slot between stacked TRs on successive floors in accordance with TIA-569. Design at least N+1 raceways to support moves, adds, and changes (MAC).

Nationally Recognized Testing Laboratory (NRTL)-rated fire assembly is required for penetrations through telecommunication space walls.

2-3.2.2 Horizontal Pathways.

Horizontal pathways are structures that conceal, protect, support, and provide access to cables between the telecommunications spaces and the work area outlet. Examples of horizontal pathways include conduit, cable trays, ceiling distribution, access floors, and non-continuous cable supports (J-hooks).

There are many methods to distribute cable from the telecommunication space to the work area, and many buildings may require a combination of two or more types of pathway systems to meet all distribution needs. The DoD-required horizontal pathway is a ceiling distribution system employing a centralized cable tray system originating in the telecommunication space and continuing out into the serving areas. Use cable trays for horizontal distribution to the maximum extent possible (maximum horizontal distance: 50 feet (15,240 millimeters) in open face hangers). The remaining pathway to the work area outlet may be implemented in a variety of ways combining conduit, non-continuous cable supports, and stub-ups/outs.

2-3.2.2.1 Open Office Wiring.

Open office wiring refers to work space divided by modular furniture and partitions rather than fixed walls. The electrical designer, the architect, and the interior designer must coordinate layout of all furniture with electrical and information communications technology outlets during the design process. Typically, furniture is selected and ordered when construction is nearing completion; without proper coordination early in the design process, field interface problems will occur.

a. Systems Furniture. Use architectural columns and perimeter walls to the maximum extent possible for information communications technology distribution to systems furniture workstations. Where permitted, use utility columns in the absence of architectural columns or when systems furniture is located away from perimeter walls.

Only if no other alternative exists, use under-floor conduits designed and installed in accordance with TIA-569. Include a spare conduit to under-floor outlet boxes for future expansion. Design systems furniture wiring connections in accordance with ANSI/TIA-568 and TIA-569.

Due to the uncertainty of final furniture type and layout, design wiring length for furniture outlets to the farthest point of each furniture group, plus 10 feet of extra wiring.
