INTRODUCTION:

This document provides direction to facilitate proper planning on the installation standards required for all Outside Plant (OSP) cabling and Inside Plant (ISP) cabling projects installed at Little Rock Air Force Base, AR.

The intent of this document is to ensure all OSP and ISP cabling projects installed on Little Rock AFB as part of any MILCON, Renovation, SABER, etc., meets commercial industry and 19 CS standards for its intended use. In the event direction for a unique installation is not addressed in this document, please coordinate with 19 CS/SCXP for guidance prior to commencing work. Under special circumstances, 19 CS guidance may deviate from industry standard, upon this occurrence, 19 CS direction will supersede the commercial industry standard for the request. For items not addressed in this document, please refer to Telecommunications Guides listed under the Reference Heading.

2.0 GENERAL:

2.1 The communications distribution system shall consist of inside-plant horizontal and outside-plant cables and connecting hardware to transport telephone and data (including LAN) signals between equipment in dispersed buildings as well as equipment within a building.

2.2 All work shall be accomplished in accordance with applicable government and commercial standards. Pre-wiring designs will consider present and future planned requirements while adhering to a flexible design layout that compliments ease of installation and management of cable routing and connections.

3.0 MATERIALS AND EQUIPMENT:

5.2 Location, Sizing, and Details: The TR will be located on the first floor along an exterior wall. It must be a dedicated space not shared with other functions (i.e. building electrical or mechanical utilities). As a minimum, the TR should have 19-millimeter (0.75-inch) plywood telephone terminal backboard (TTB) (19 CS reserves the right to request additional TTB’s if necessary).

Floors, walls, and ceilings must be treated to eliminate dust. Finishes must be light in color to enhance room lighting. Do not locate the TR near other building utility rooms or generators that may cause electromagnetic interference with TR equipment or where moisture, gases, dust, or other contaminants may enter. The TR size for DoD buildings is 10 feet x 8 feet (3m x 2.4m). Generally, the TR should be sized to approximately

1.1 percent of the area it serves. For more specific design guidance refer to UFC 3-58-01, para 2-4.2.2.
