1. INTRODUCTION

1.1 Purpose

The purpose of this document is to provide technical guidance for engineering, interfacing, and implementing Federal, military, and commercial long-haul transmission systems for selected United States (U.S.) Army projects and installations. Also included are non-Power Projection Command, Control, Communications, and Computers Infrastructure (P2C4I) transmission systems at the installation level (trunked radio, cellular). The technical guidance in this document provides the basis to develop more detailed system design, engineering, and test plans for specific projects and installations. The underlying objective is to meet current information transfer requirements (voice, data, video) by providing long-haul and selected installation-level transmission systems and services sufficiently flexible to meet exponentially increasing communication requirements, be interoperable with installation-level information systems (sustaining base and tactical), and to accommodate new technology advancements.

1.2 Background

As stated in the Technical Architecture Framework for Information Management (TAFIM) a new technology paradigm based on the concept of open network computing is emerging. It is driven by advances in technology and a combination of growing interdependence and heightened competition among functional organizations. The design of an AIS is increasingly dependent upon data communication and system platform operations in a distributed processing environment to satisfy users' requirements during peace, transition to war, and wartime. Standards are "the glue" that enable users to interoperate seamlessly across applications, platforms, and organizations. The standards herein are drawn from widely accepted commercial standards when they meet Department of Defense (DoD) and Army requirements. Where necessary for interoperability, profiles of commercial standards are used. Military standards are mandated only when suitable commercial standards are not available. The DoD Joint Technical Architecture (JTA) makes use of the open-systems architecture used by the Internet and the Defense Information Systems Network (DISN). This architecture and set of standards provide for communication interoperability between end systems that are on different communication subnetworks. This document will provide guidance in the design, engineering, and implementation of long-haul transmission systems to support end-to-end communications interoperability. It will ensure that Federal, military, and commercial long-haul transmission systems are being utilized to provide an information infrastructure that is transparent to the warriors but accessible by them anywhere.

1.3 Goal

The Army developed this document to assist the engineer in the design and implementation of selected long-haul transmission systems to ensure they are scaleable, interoperable, secure, and in compliance with the Army Technical Architecture (JTA-A). The long-haul transmission infrastructure must support the ability to structure a force rapidly and efficiently to meet any future contingency.

1.4 Scope

This document identifies the standards, profiles, and practices for information transfer required for interoperability between and among Standard Army Management Information Systems (STAMIS) and Command, Control, Communications, Computers, and Intelligence (C4I) systems, supporting access for data, facsimile, video, imagery, voice, and multimedia systems. Also identified are the standards for internetworking between different long-haul networks and subnetworks. Transmission media standards for satellite and terrestrial radio, fiber optic and copper cable, Government and commercial services, and technical controls are covered. Finally, emerging technologies that should be monitored for future use are identified. This document is intended to be used as primary point of reference for the integration and synchronization of long-haul and selected installation transmission systems within the Army.
