1.2 SYSTEM DESCRIPTION

NOTE: Ensure that the design provides for adequate communications pathways and spaces using EIA ANSI/TIA/EIA-569-C as a minimum requirement. Coordinate electrical, grounding, and HVAC requirements with the associated disciplines. Network type, size and configuration must be coordinated with the user's representative, if known. The same cable pathways and spaces shall be used for both telephone and data (including local area network) systems. However, Secure and classified areas should meet requirements of NACSIM 5203 AND DIAM 50-3 for cable distribution and wiring.

The premises distribution system shall consist of inside-plant horizontal, riser, and backbone cables and connecting hardware to transport telephone and data (including LAN) signals between equipment items in a building.

3.5 ADMINISTRATION AND LABELING

3.5.1 Labeling

3.5.1.1 Labels

All labels shall be in accordance with EIA ANSI/TIA/EIA-606-B.

3.5.1.2 Cable

All cables will be labeled using color labels on both ends with encoded identifiers per EIA ANSI/TIA/EIA-606-B.

3.5.1.3 Termination Hardware

All workstation outlets and patch panel connections will be labeled using color coded labels with encoded identifiers per EIA ANSI/TIA/EIA-606-B.

3.6 TESTING

Materials and documentation to be furnished under this specification are subject to inspections and tests. All components shall be terminated prior to testing. Equipment and systems will not be accepted until the required inspections and tests have been made, demonstrating that the signal distribution system conforms to the specified requirements, and that the required equipment, systems, and documentation have been provided. To support this initiative, an appointed 62d Communications Squadron Quality Control (QC) representative shall observe operational tests, and analyze both observed and annotated test results provided by the contractor. Any system, equipment, or hardware that does not meet Department of Defense (DOD), manufacturers, or ANSI EIA/TIA standards shall not be accepted. All discrepancies must be re-tested/re-inspected and the results certified correct in writing by the 62d Communications Squadron QC representative prior to any final acceptance.

3.6.1 Unshielded Twisted Pair Tests

All metallic cable pairs shall be tested for proper identification and continuity. All opens, shorts, crosses, grounds, and reversals shall be corrected. Correct color coding and termination of each pair shall be verified in the communications closet and at the outlet. Horizontal wiring shall be tested from and including the termination device in the communications closet to and including the modular jack in each room. Backbone wiring shall be tested end-to-end, including termination devices, from terminal block to terminal block, in the respective communications closets. These tests shall be completed and all errors corrected before any other tests are started.

3.6.2 Category 6 Circuits

Twenty five percent of the “voice” installed category 6 circuits, selected on a random basis and all “data” category 6 circuits shall be tested using a test set that meets the Class II accuracy requirements of ANSI/TIA/EIA-568-C-2 standard. Testing shall use the Basic Link Test procedure of ANSI/TIA/EIA-568-C-2. If more than 5 percent of the “voice” category 6 circuits tested fail, then all “voice” category 6 circuits shall be tested. Cables which contain failed circuits shall be replaced and re-tested to verify the standard is met.

3.6.3 Shielded Twisted Pair

Note: During design phases of contract, consult local communications

Agency representative to determine validity of shielded

Twisted pair cable installation requirements for proposed
