2. REQUIREMENTS.

2.1. Appendix B contains the recommended equipment to maintain a standardized configuration on Charleston AFB.

2.2. Cabling

2.2.1. Data/Voice. All installations will consist of Category 6 Plenum-rated, Purple Unshielded Twisted Pair (UTP) cables with RJ45 connectors. Telephone House cable will be terminated from the Building Entrance Terminal (BET) to a S110 19 inch rack mount panel. If Shielded Twisted Pair (STP) is installed, both connector ends must be grounded to prevent electromagnetic interference.

2.2.2. Wiring Pattern. Charleston uses the T568B wiring pattern. See Appendix A for the actual wiring diagram. All connectors will be securely attached to the cable for added strength and prevention of signal loss.

2.2.3. Fiber Optic. Fiber optic cables on Charleston use the duplex SC-type connectors. Any new Single mode fiber will be 8.1/125-micron cable.

2.2.4. Coaxial Cable. Any coaxial installations will use a 75-ohm plenum broadband cable rated for the correct distance requirements. The table below, took from the USAFE Premise Wiring Standard, lists the cable type with corresponding distance limitations:

Cable Type Maximum Distance

RG-6 <=250 Feet RG-11 <=400 Feet RG-59 <=150 Feet

2.2.5. Patch Cables. NIPRNET patch cables will be provided at appropriate lengths to provide for cable routing and management, they will be less than 3m (9ft) from the switch to the patch panel and less than 6m (18ft) from the workstation to the wall jack. Cables colors will be coordinated with building customers and the 628 CS/SCOI. SIPRNET cable length will depend on the location but must be STP, conform to the overall distance requirements, and be red in color to denote its classified nature.

2.2.5.1 Phone patch cables will have an RJ45 connector on one end and S110 1 or 2 pair connector on the apposing end.

2.3. Telecommunications Rooms (TRs), Hallways, and Office Installations

2.3.1. Cabinets/Racks. All cabinets will be properly bolted to the floor and grounded to a 6mm x 103mm solid copper grounding buss bar with insulated standoffs. This bar must be connected to the central building ground by a 6 AWG insulated copper cable. If a rack is used instead of a cabinet, it must also be securely mounted to the ceiling or wall to prevent possible bending.

Although discouraged for use, wall cabinets follow the same grounding requirements as racks and full cabinets. Additionally, the cabinet/rack will contain a duplex 20A, 110VAC outlet for equipment use.

2.3.2. Cable Supports. Cable ladders (or trays) are the preferred distribution system throughout the facility when possible. If ring or hook supports are used, cable sags must be minimized to reduce stress and avoid interference with the ceiling tiles.

2.3.3. Electromagnetic Interference (EMI). Care must be taken to ensure EMI sources do not interfere with installed cabling. Ensure that all telecommunications cabling cross lighting and power cables at right angles only. Per the EIA/TIA 569, minimum distances from EMI sources are:

a) 1.3 m (4 feet) from large motors or transformers

b) 27cm (1 foot) from electrical power cables

c) 129mm (5 inches) from fluorescent lighting

2.3.4. Patch Panels. All patch panels will contain vertical and horizontal cable management systems.

Route all cabling through these and the switch cable management. Large amounts of cables traversing equipment racks should use a reusable tie strap (i.e. Velcro straps) to facilitate changes, present a professional appearance, and aid in troubleshooting.

2.3.5. Power. Every TR must contain a minimum of two (2) 15A, 110VAC outlets on the wall closest to the cabinet/rack. Furthermore, Uninterruptible Power Supplies (UPS) will be installed in every TR for backup power. These UPS must supply 110V single-phase power to all equipment for 15 minutes after commercial power loss.

2.3.6. Heating, Ventilation, and Air Conditioning (HVAC). Per the AMC Premise Wiring Standard, the TR will be environmentally controlled at 64 – 75 degrees Fahrenheit and 30% - 55% humidity 24 hours/day, 365 days/year.

2.3.7. Panduit. Ensure a uniform and professional appearance is maintained throughout the facility.

Install wall boxes at same height as electrical outlets, place caps over all joints, and ensure raceways are level.

2.4. Telecommunications Systems Administration and Labeling

2.4.1. Jacks are numbered numerically clockwise around the room starting at the door.

2.4.2. All fiber optic patch cabling labels will show the From/To Building number – Patch Panel port number – switch port number

Example: Fr 203 to 214 – 5 – 8/1

2.4.3. Provide layout cut sheets to the 628 CS/SCX offices upon installation completion.

2.4.4 Numbering and Testing Communication Outlets: All jacks must be numbered, mapped, distance of the run determined, and tested to meet current EIA/TIA 568A standards. Identify each jack as to circuit number on face of wall jack and patch panel. Three copies of the building floor plan showing the location of the jack numbers and run distance and a test report shall be given to the Contracting Officer upon completion of all testing. Contact the 628th Communications Squadron Plans Flight (843) 963-3982 at least 24 hours prior to performing tests. Any system, equipment, or hardware that does not meet Department of Defense (DOD) manufacturers or requirement standards shall not be accepted. All discrepancies must be re-tested/re-inspected and the results certified correct in writing by the 628th Communications Squadron. All copper twisted pair cable must include tests for the following: Opens, Shorts, Grounds, Continuity, Polarity,. Provide a copy of the circuit test printout. The circuit shall be tested for proper pinout, dB loss, Near-End Cross Talk (NEXT), cable length, and overall category rating.

Any circuit that has improper pinout, dB loss, NEXT, cable length, or does not meet the Category 6 rating shall be re-installed until it passes all tests.

2.4.5 The contractor shall provide at least one on-site supervisor who has a minimum of 2 years experience in wiring, terminating, and testing telephone and data transmission systems. Proof of qualification will be provided upon request of the government contracting office. The Telephone and Local Area Network (LAN) cabling/wiring systems shall be complete and functional.
